It also incentivizes leaks from insiders, sometimes endangering others. A soldier was charged for betting on a military operation. https://www.justice.gov/opa/pr/us-soldier-charged-using-clas...
And of course throwing pro sports, but that's been happening for ages. Sports has always been crooked: eg the Eupolus Scandal from 388 BCE.

It's bad enough when such systems fail due to whatever sort of issue, but the last thing aviation needs is people intentionally blowing holes into the swiss cheese security model -.-

It's easier to stop incentivizing people to ruin the commons, vs. trying to strengthen the commons against all possible adversarial behavior.
It's impossible. No matter how good of a job you do, there will _always_ be people out to watch it all burn.
Even foreign actors during war time wouldn’t go through the effort of messing with individual temperature sensors.
> You aren't allowed to set up a life insurance policy on someone else's life, or a fire insurance policy on someone else's home
This isn't really true. Lots of people take out life insurance on others as a hedge for many reasons, small business partner is one. Same fire insurance, we had a case where someone pledged a building as collateral and we took out separate fire insurance on the building so we'd get paid out immediately.
I'm not sure where this false premise started but alot of people believe it.
This is done because the insurance company wants you to prefer that the covered event doesn’t happen, which avoids some conflicts of interest.
These prediction market events don’t have the usual insurance interests involved.
> This is done because the insurance company wants you to prefer that the covered event doesn’t happen
But buying the insurance cancels exactly that. Insurance fraud is a thing.
You can get insurance without the above provisions, but it will cost a lot more. Once in a while someone manages to collect on a claim for loss of their expensive cigars after they smoke them - but this is rare and usually not worth the cost.
This may vary by country, it isn't a subject I'm particularly familiar with, but at least in the UK that isn't true - many, I think most, life insurance policies here do pay out for suicide. There's just a period of years between the start of the policy and when suicide starts to be covered, to prevent people who are planning on killing themselves from being able to take out insurance just before doing so.
if there is evidence that someone took out the policy with the intention of creating a claim then the insurer may treat it as fraud and decline it.
Yep, we're in full agreement here
Evil, but most everything in real estate is evil.
With an insurance this trick won't work, because the insurance company will notice what you are doing. Polymarket doesn't care.
This has worked well millions of times (and occasionally failed too with people ending in prison or with huge fines). Where I can agree however is that Polymarket makes that much easier.
You're not allowed to take out life insurance on someone you don't know or have a relationship (business or otherwise) with.
Life insurance on a business partner works. Life insurance on your spouse as well.
Life insurance on the leader of a random country? Unlikely
you dont take out cover on your business partner, the company itself does
It being the driving plot behind Double Indemnity probably started it. I always thought it was true until your comment, too.
If you wanted to correct a misconception, you should provide a better, more complete understanding, not just express frustration about a misconception that doesn't even exist outside of an uncharitable reading.
In this case, that means refining the point to the more accurate model, that you need an insurable interest -- i.e. reason you don't want the event to happen, even knowing you'd get a payout[1]. Your counterexamples only work as such because that exists![2] If you want to fix all the people who don't have your superior understanding, that would have been a great way to help them out.
>I'm not sure where this false premise started but alot of people believe it.
It exists because it's approximately true: you can't get insurance on 99.99999% of buildings in the world because you have no insurable interest in them. And any time someone could correct that false premise, they probably just complain rather than providing the complete understanding -- exactly the choice you just made here.
[1] IMO, this is the natural dividing line between gambling and insurance https://news.ycombinator.com/item?id=13916088
[2] Edit: And in your building collateral example, the policy would prevent you from double dipping -- getting both the building and the full payout.
To be clear they had explicitly written in the contract from the start that death didn't count. And they paid out the full amount - just not to the same betters they would have if he had left office alive.
You can sell your life insurance policy to somebody else. It's a way of getting money to sick people to use while thy are still alive.
Polymarket is facilitating bets between people, not bets with the house. Gambling and insurance are both bets with the house.
What jurisdiction are we painting with that broad brush? This is far from universally true, even in the US.
Yes, there are de minimis exceptions. Your office NCAA pool, for example, is often legal, but it has nothing to do with what we're talking about and is also irrelevant to a business facilitating it via 18 U.S.C. § 1955.
https://russpain.com/en/news-3/authorities-consider-legalizi...
>Rarely exceed 25 euros.
Maybe in Christmas, because the weekly play was just about low prizes.
A bet is a bet, whether it's against the house or other people it's a bet.
Any bum defending these contracts is to me either a shill or way too dumb to understand the concept of incentives.
Oh and there was an Israeli journalist that got life threats because he reported that an Iranian missile struck some place in Israel, and apparently there was a huge bet on it on polymarket.
I would argue that the ratio between "power" and "money to be won" is too big (at least right now) for this to materially matter. No fortune 500 CEO is going to postpone a product launch so they can win $5,000 on polymarket. But some random guy will get his hair dryer to win a socially meaningless weather bet.
It's not discussed often, but the liquidity of these markets is often awful, and you can only win as much as people are willing to take the other side. Which is harder when people know it's easy for insiders (or the outcome decider themselves) to play the other side.
Basically the more socially consequential the outcome you control, the less likely you care about a betting market, and the less the betting market cares about you.
The real winners are people with little or no power to effect outcome, but with insider knowledge. And athletes.
No, but a low paid frontline worker with the ability to throw a last minute wrench into the gears absolutely would.
Usually though people's pay/power directly correlates with how badly they can screw the company if they go (legally) rogue.
But anyone can get a job at XYZ, buy puts, and go and set the factory on fire the next day. Betting markets don't change the fact that you'll be arrested, except that you'll be arrested for a few thousand dollars rather than whatever you can squeeze out of options.
You're basically arguing that there aren't enough fools to go around, when we're talking about gambling enterprises.
Welcome to the grift economy, take a number.
If I find out my friends placed bets on whether I'll say X tomorrow, I'm not obligated to act as if I didn't know.
you might need to take your imagination and critical thinking out for a spin if you can't see where this leads.
This isn't share price manipulation.
I'm pretty sure this is the same as match or race fixing to get the payout from bets made.
They would win a lot more than a trivial amount by taking adverse positions, no? Seems like you're making up your own hypothetical
Think of it like kids betting pennies what subject the teacher will open with the next day. The teacher doesn't care about winning $0.89, but the kids do.
Nobody's making millions betting on things like the weather.
So what's the point of polymarket, then? If at best we get "negligible" "insiderism", how is it that we are supposed to be benefitting from this as a society the way OP and others insist that revealing insider preferences "would"
An example would be the latest presidential election, where professional pollsters at them at almost 50/50, but the prediction markets had trump by a landslide. He went on to win even the popular vote.
The benefit comes to people who don't even participate, and just take notes.
Trump didn't win by a landslide and he barely won the popular vote...
>The benefit comes to people who don't even participate, and just take notes.
Praying someone has an example besides the election, to which it seems to have made absolutely no difference at all
As for the election, a Republican winning the popular vote by a couple million can't be called a landslide in nominal terms, but it is in terms of normal results. The DNC currently completely controls California and New York. After those 2 states alone Trump was down 7 million votes in 2020. The rest of the states tend to be either very small or relatively competitive. To make up the popular vote amongst them requires a very large edge. Polymarket had Trump as a 2:1 favorite the day before the election, and he would indeed go on to win every single swing state. The corporate media and their associated pollsters had Harris ahead.
I have a bot betting on a handful of what I consider (so far) markets that are impossible to cheat (bar UMA shenanigans): nobody has any control over the outcomes, previous knowledge is very limited. It makes some money, but looking at the depth, the volume, and my metrics, even being the fastest 100% of the time without worrying about bankroll, one of them would gimme roughly $1-2k a week.
Then there is also the fact that the power of the people determining the outcome is inversely proportional to their care about betting markets.
Put this together and you get "The larger the size of the market, the less the people who can single handily swing it care about doing so".
If you are someone who can command hundreds of thousands of people to bet millions for or against you, you almost certainly lose more than you would gain by gaming it.
Mind you the market also naturally prices in this risk of the one person going rogue and taking them winnings for themselves. You will never find a market for "WarmWash will post nothing for 3 days straight on HN" because no one will take the other side of it.
Single moms historically don't have tons of extra money, and Trump was ostensibly a billionaire.
There's plenty of people able to influence events to whom these barely liquid bets can still amount to huge pay offs.
That includes many CEOs whose compensation is tied to stock performance.
https://en.wikipedia.org/wiki/Borussia_Dortmund_team_bus_bom...
Its a small step from betting on ships sinking to making sure they go down.
This happens on the stock market on a scale 100x larger than Polymarket.
c.f. manipulated earnings reports, taco trades, strait of hummus nonsense
Polymarket is quite tame in comparison, in my opinion.
How does the same line of argument not also suggest that stock markets be prohibited?
Thanks, stranger!
Do you really think that there are no people, who have bet on the price of something in one direction or the other, who enact real world consequences on people or other entities in order to ensure their bet? This is par for the course.
I would replace them with https://manifold.markets/ or maybe heavily regulate them. they do have practical utility in forecasting
> Play money means it's much easier for anyone anywhere in the world to get started and try out forecasting without any risk. It also means there's more freedom to create and bet on any type of question.
Their investors/lawyers probably did not want to back the risk using real currency adds.
How do I cause someone to die using Kalshi or Polymarket, specifically, also without being caught? Didn't they catch someone that had pre-knowledge of the Venezuela campaign?
(I'm not asking because I want to do this, I'm asking because it's not clear to me how this is realistically possible.) Also, given that you can't just create a market on either platform, it's not like I can just say "XXX has 3 months to live".
If a criminal wants to make money on crime, they have better ways to do it than put 10k of their own money to make 50k by killing someone.
I just don't get this whole argument. If you're a contract killer, why put yourself and the contractee up in the feds sights?
Assuming you get away with the murder, guessing that's not the part you're asking about, a concrete example: https://polymarket.com/event/next-french-presidential-electi..., bunch of people on that list, surely many of them are like the typical European politician, mostly without assassination protection most of the time. Place a "No" bet on one of them, then hire someone to assassinate, and Polymarket indirectly drove someone to murder another person, as they could profit from it.
As a contract killer, I don't think you'd put yourself or your client more up in the fed sights than without Polymarket, it'd just look like another bet.
This is the same reason it is generally illegal to make public statements lamenting that someone hasn't killed a person.
https://en.wikipedia.org/wiki/Will_no_one_rid_me_of_this_tur...
I don't know if a contract is a good way, but it gives some deniability.
You can also follow people. Tax fraud is how a lot of criminals are caught - we don't know what you did but we can prove you didn't get the money legally and that is enough.
These markets decentralise that information asymmetry.
The astute observer might say "ah but what about crypto gambling sites like Stake?". This problem isn't as intractable as crypto bros might have you believe. You simply issue arrest warrants for people who allow your citizens to gamble in violation of your local laws and you threaten any bank, brokerage or financial institution that allows them to convert their crypto in fiat currency. This is fairly easily covered by KYC/AML regimes alreaqdy. It won't be perfect. It doesn't have to be. As soon as someone can't be an open billionaire by selling crypto gambling without fear of being extradited to the US if they travel internationally, the shine disappears real quick.
Sadly, from my point of view, you're right that right now going after the on/off crypto ramps would be enough to dissuade most people from using crypto gambling sites. I hope for a more educated populace that can bypass these laws and engage in whatever consensual activities they want to, as long as they're not directly harming anyone.
No. That's not how society works. Prediction markets have externalities that affect all of us.
If you want to gamble, you should be allow to do it in a small setting, on games that have no effect on the greater society.
Unregulated gambling has very obvious externalities. Don't insult our intelligence by suggesting it doesn't.
Because otherwise, I don't think this conversation is going to lead anywhere.
Let's not pretend that Spain of all places is caring about horribly destructive psuedo-gambling.
Banning "unregulated gambling" is just pressure to make sure that the Spanish gambling racket stays intact for the bookies already at the top.
Is this intended to imply that Spain has particularly high levels of sports betting, or issues with gambling? All the stats I can see suggest the opposite, and there's already plenty of tight restrictions on local gambling businesses (sports sponsorship ban, welcome bonus ban, almost no public advertising, etc). At a quick google, it looks like the 'Spanish gambling racket' for sports is tiny, gambling problem stats far lower than UK/France/Italy, and most gambling that does happen is the lotteries etc instead, which has its sins, but is a very different beast.
Is there something specific you're getting at?
Not a fan of lottery myself, but at least it's just some random numbers drawn from a drum. There is hardly any dark pattern or illegal incentive there. It is just you against Thomas Bayes.
La Quiniela, a lottery based on soccer matches' results. Every middle aged man filled some weekly forms (win for locals/draw/win for foreigners) as if it was a religion. If you matched 14 from 15 results (much better with 15), you could get a big prize. Also, Jai Alai matches on the North of Spain had huge bets on results too.
Younger millenials and Gen-Zers will just play on RETA which is kinda the same as La Quiniela but online.
I feel like this might be a net negative from the pure speed and access in which you can lose money online vs real life, but idk.
Do you think regulation of all possible categories of people who could behave adversely to influence prediction markets would be preferable to just regulating the market itself?
"Prediction market" ads running constantly on both sports channels/websites like ESPN. Shortly followed by mainstream cable news like CNN featuring Polymarket stats as a routine part of their horserace polling coverage. Gambling is now an omnipresent temptation for anyone even casually interested in following sports/political news.
And now millions of young men who previously would have had to seek out niche illegal venues to gamble have several dozen different apps on their phone offering to light their disposable income on fire by clicking a couple buttons every paycheck.
Sports betting places on the other hand have multiplied like fungi in the last two decades, unfortunately.
You're probably talking about the big Vegas style entire-hotel casino that aren't so popular in Europe anyway outside a niche crowd. The average lower class Spanish person frequents these "sports bars" heavily
Allowing prediction markets to overlap with criminal incentives is a platform TOS and moderation problem; not a prediction market or betting exchange problem.
What in the fuck are you talking about? This is a public policy problem and has been literally for 3,000 years.
It's one of the oldest and most pervasive public policy problems that has spanned nearly every culture that's existed since there was culture.
In 2017 someone tried to bomb the bus of the BVB soccer club, after he bought puts options on the BVB stock.
https://en.wikipedia.org/wiki/Borussia_Dortmund_team_bus_bom...
What you describe (profiting from creating havoc by some "short" bet) is indeed problematic and is regulated.
This is also one more reason why trading should not be unconditionally anonymous. Another reason: proper trading venues have rules against "squeezing", namely that no entity may hold more than some threshold ratio of the open interest. That's obviously impossible to enforce with anonymous markets.
[1] Tradings allows individuals to time-shift consumption, it funds productive enterprises, it incentivises convergence of market price with fundamental value, which in turn is what enables efficient investment allocation, and it allows the emergence of an economy-wide equilibrium of savings and investments. Note though that all of these functions might well be fulfilled by having, say, one minute of trading a day.
The language is usually "This market will resolve to “Yes” if <politician> ceases to be <Prime Minister/President/whatever>".
Or for another example: https://polymarket.com/event/will-neymar-play-in-the-2026-fi.... Will Neymar play in the world cup? Not if he's dead. Any kind of "will celebrity appear in X in the future" can be reduced to an assassination market.
https://xcancel.com/mansourtarek_/status/2029996077554815268
Not sure if Polymarket does the same. Also not sure if I really trust these people to be the arbiter of morality and adhere to their own rules when it doesn't benefit them.
> A registered entity shall not list for trading or accept for clearing on or through the registered entity any of the following:
> (1) An agreement, contract, transaction, or swap based upon an excluded commodity, as defined in Section 1a(19)(iv) of the Act, that *involves*, relates to, or references terrorism, *assassination*, war, gaming, or an activity that is unlawful under any State or Federal law.
Polymarket doesn't seem to care too much.
Polymarket is now two separate entities. Last year they were banned from the US and stopped taking on new US customers and made their site withdrawal only for anyone based in the US. You could bypass it with a VPN, but they did enough to at least look like they were complying.
They've now created a separate company that I believe is called Polymarket US which has it's own version of the site/app which they are using to re-enter the US market. This switched from invite only beta to open sign ups a few months ago.
Polymarket US is mainly just sports betting with a small number of crypto, commodities, and political election based markets, although they have said they plan to expand their market options. Their US based site almost certainly doesn't violate those rules. The version that is used outside the US is the one that has markets that violate that, but since they're not in the US, there's not much that can be done.
In other words the money spent on bets that involve killing directly foments more killing.

It's not at all obvious that leaks of classified information are per se detrimental to _actual_ national security.
We experimented with extending this to non-esports topics during the election, which led to a bunch of Trump-based predicting. Then Jan 6 happen and the whole site went to hell. I pivoted the product because I just didn't want to deal with running a site like that.
Seeing what is happening with these sites makes me feel good about my choices. If I were in charge of a product that enabled this I wouldn't sleep at night.
Fortunately we have big beautiful crypto that separates us.
There are the people from the kill command who bet on what they are ordered to do.
There could even be a bet by someone with direct influence on the government who convinces them to do it to make some money.
There are several things about the "these are good because people can hedge" argument which bother me and I struggle to disentangle them, but one facet is this: These betting-markets may be an inferior form of hedging, especially for non-trivial scenarios that are intended to evoke sympathy. (Civilizations have a lot of prior art in risk-management.)
For example, our statistical Iranian Dude may be much better-off using their bet-money for targeted purposes, like stocking up on useful imported durable goods that may become unavailable, ideally ones that would have resale value even if nothing bad happens.
The convenient online casino doesn't require any more than a vague sense of anxiety to bet, but that generality also limits how well you can use the money to protect yourself. If you're specifically worried about famine, better to arrange a future result of food, versus a payout of cash when nobody is selling food. If you're a factory that uses X as a manufacturing input and worried about a geopolitical blockade, you may be better off investing in alternate supplies or futures contracts for X.
Aside from the government, who is it that you prefer to do judgment and enforcement?
And yes, you can construct an argument to ban polymarket that does not rely on morality too. But don’t try to sell it to me with a “we will ban it because it’s eeeeevil”.
Ok, I'll bite. Why is it bad to deprive you of your possessions?
And given that the house always wins, is it not depriving the gamblers of their possessions?
This assertion also hinges on morality. Why is being deprived of your possessions bad. You ultimately have to reach for an ethical framework to justify it.
I'd say, because we as a group decide they are "bad".
Not sure how you can remove moral judgments from any discussion of banning
Which are valid arguments in your opinion?
Yes, of course CNN is evil. Is this still even a matter of debate?
Just naming things differently does not work in other countries.

Now they encourage users to bet as part of the commentary.
I see the percentage of advertising devoted to gambling to be a similar bellwether to the decline of my whole country. And it’s getting worse all the time. I can’t turn on the tv, look at billboards on the freeway, watch a sporting event, or even walk down a supermarket checkout without getting constantly reminded of how far we’ve fallen.
gambling happens, tax comes in, crime goes up, police get hired, politicians get the police vote
Kalshi and Polymarket require you to provide your SSN.
Spanish congress approved recently a way to stop such a thing.
Not really how it works in practice here, some Cloudflare IPs are unavailable for a few hours, everything mostly keeps working as it always is.

It's like calling the casino a probability market.
(Which of course doesn't make it any better or less of a casino, this is just to say that the word market didn't come from nowhere)
I don't think you'll find a simple/useful answer by slicing the problem on that axis.
You don't get anything outside of winnings or losses from your bets on a "prediction market".
That’s what I mean: Many things can be used in very different ways. These incentives usually matter more than the underlying things in finance.
I think you might be mistaken about how Polymarket works. They are indeed only a platform operator; all trades are directly between participants.
Complete shamelessness all around.
Prediction markets are also regulated by the CFTC as they're futures contracts technically.
It's important to remember that ~80% of activity Polymarket and ~90% of Kalshi, by volume, are sports. These are effectively sports betting websites with prediction markets on the side.
I mean Spain blocked these markets for now, to investigate how to deal with them, I don't think it's for sure they'll be classified as gambling and allowed, might very well be outlawed. Probably parent got confused you said "The whole world will eventually do the same" (about blocking/banning) but then seemingly you thought these were "classified as gambling" already.
It not until recently ISPs got asked to do blocks by IP, as Cloudflare wasn't responding to legal takedown requests, hence we currently seem to experience both types of blocking, but the IP-based blocking happens a few hours per week, the other ones are permanent.
They've got a license to stream LaLiga on Movistar Plus so they're particularly interested in blocking piracy.
Other countries such as USA work in a similar manner. Work permits such as green card, to name an example.
The people who complain about regulations and law either don't understand why they exist or how they work, or they have an interest in the abolishment of it because they benefit from that.
Then you get that BS about how USA is better off than EU. Well, if you're healthy, educated, and employed, sure. Otherwise? You can just use your eyes. Go drive through a rich and poor neighborhood in both. The poverty in USA is horrendous, and the effects are shown. We got poverty too, but not as severe. No need to go to that area between West and East coast. You can experience this right near the Bay Area. San Jose is supposedly a mess. I'd love to compare my visit to a Fry's in San Jose 2005 with today's.
Fry's closed in 2021.
This has nothing to do with US vs EU or any other trope you seek to my comment as being on a particular side of of a particular issue in order to get people of a certain bent to support whatever your side is (isn't team politics great).
Ask yourself this. If the license Spain is trying to enforce here had the exact same requirements but was granted by some 3rd party (industry consortium or whatever) and the government didn't care whether they held it would you still be acting like it's such a big deal for them to have it or not?
Does holding the license or not fundamentally change the nature of the business the license holder is in?
The government is essentially granting legitimacy to a bad thing here in exchange for some money being spent in the right directions and enough of it on "good things" that it's plausibly deniable.
I didn't expect you to agree either. I wanted to inform the reader and lurker, not convince you. Why you have to resort to 'you are exactly the kind of person' is beyond me.
Since you decided to edit your post, so have I:
Yes, a government can outsource/delegate such, if the quality is good, why not? For example, the audit has to be thorough and the outcome non-discriminatory.
As far as I am concerned it is a very sick platform because (well anything related to cryptocurrency is) some of the bets are about dark things, seemingly allowed. For example, imagine being able to bet when the next murder of the Zodiac is happening, and how it'd occur. Same with the missile example. Should we therefore ban or regulate it? I don't know what is wisdom. But I do know EU and Spain can decide on this for themselves. One thing of note: insider trading is illegal in EU, yet Trump's clan hobby (yes, in past presidency it occurred as well, but not as severe, nor as ridiculous).
"I really ought to throw this umbrella away. I know we're in a rainstorm, but I haven't gotten wet yet!"
The buyers and sellers are not the only ones there, there is also the companies injecting money into it via dividends and stock buy backs, I can be a winner on the stock market without there having to be a loser.
Spain is a hub between Atlantic and Mediterranean countries and South America and a good chunk of the US. Trade against Atlantic countries isn't something alien to us (just ask the Brits in the Industrial Revolution) and the Mediterranean, well, since Iberia, Carthago and Roma...
Spain sucks because the economy can't compete with North Italy? Well, it's miles ahead against South Italy, even the South of Spain hasn't a second world vibe like Italy down from Rome. We are more balanced at least and South with companies like Airbus are thriving.
That ^ is mostly true today.
If you have access to Polymarket or Kalshi, you have internet access. If you have internet access, you have access to more public knowledge than any previous generation.
Whether you use the internet to educate yourself or to gamble should be your choice. But starting today, it is no longer your choice in Spain.
That didn't happen. The internet didn't solve disability, it didn't solve education, it didn't solve misinformation, didn't stop scams. In fact, it has made some of these things worse.
Pretty shocking to see all the replies you got though. Over the last 10-20 years there seems to be a drastic increase of people who think government control is a good idea.
I haven't noticed an increase - roughly half the country tends to be in favor of this at any given time. Perhaps you've just widened your circles a little?
PS If we are going to talk about Spain, calling Americans fascists doesn't really work. They have actual Fascists there and their government policies are far (far far far far far far far) closer to the blue team. Anyone with even a passing familiarity with Spanish politics would know that.
Fire departments are good for the community at large as well so the fire at your house doesn't become the fire at my house.

I think that self fulfilling prophecy attempts by deep pockets trying to sway markets by bucking trends generally transfers money from more to less foolish bettors.
If anyone, including your surgeon, can take that life insurance policy based on your life, things can go bad pretty quickly (hint: what happens if a profit-maximizing surgeon would earn a lot more money from your policy than from his regular job?).
If it is someone else's? Bad, because I'll just take a life insurance on them and then promise the doctor half of the proceeds if they ensure that the outcome of the procedure leads to an insurance payout.
Why are the sports odds useful? Word mention market and sports market are the majority of bets after all. Seems like >90% of wagers are useless noise.
Name 7 recent useful ones you actioned based on, one for each day of the last week. I’m very curious what those may be that you use it daily.
When I looked a the site and checked out a few non sport/word wagers, the actual bets were pretty unhelpful because while their summary sounded potentially informative the actual fine print showed that a weirdly constrained timeline of a specific thing was the actual deciding factor, making them useless.
A better example is wagers on things like when the Iran war will end. That's actually useful 'wisdom of the crowds', and any insider trading is already illegal. Maybe someday those markets would get big enough to allow companies to hedge risks. That's an actual useful application of PMs.
One issue is that prediction markets provide financial incentives to perform actions in the real world. For example, if I want a head of state murdered, I can wager lots of money that they won't be murdered. If somebody wants to earn that money, they can simply bet against me and then murder them.
It's not an dispassionate wager like betting on roulette, it's a wager that directly influences the real world, at least a bit.
Of course you could directly hire an assassin, but that doesn't come with plausible deniability.
I would not be surprised if people are murdered at some point to reap the payout of some related bet.
