If the prediction market is for a non-trivial amount, it's likely someone is going to kill you in exchange for the money the prediction market offered them. The prediction market isn't acting as a prophet here, it's acting as a plausibly deniable murder for hire service and you are its victim.
The people "betting against" you dying just paid to have you killed.
This was discussed on polymarket with the Galve Goat burning bet and assume it's why
Essentially it's a big straw goat in Sweden that vandals sometime set on fire.
Right towards the end as the probability approaches zero there's a huge profit incentive, "done deals" usually go under well under 1¢ meaning 100-200x returns.
A US man once traveled to Sweden to set the goat on fire, he was caught, fined $20k(?) and then fled the country before paying the fine.
Risk reward in a situation like this absolutely creates a situation for prediction markets similar to the observer effect in physics, it's no longer predicting the future and instead altering it.
I think as this becomes a reality, in general people will stop trading so close near the deadline for so little gain.
As it gets closer to the deadline, the timeframe shortens, so the gain does increase. A 1% return which you're paid on tomorrow is a 3,778% annualized return.

Exactly, these markets exist in the real world, so as their size and use increases, the more likely the odds will influence real world events. Look at sports betting for a much smaller example. Match fixing is known. Electricity markets are gamed for individual profits at the detriment to everyone and the stability of the system, even with regulators trying to keep things stable. Enough "Market for all the things" already..
The type of people who have the power to change decide these type of events already are able to use that power to make money in a thousand different ways. These markets will change nothing.
> Enough "Market for all the things" already..
See, there are two major flavours of pro-market attitudes. The first one is "if we allow many independent individuals to try their own approaches to a problem and let the people with "better" approach to personally profit from it handsomely and make them compete against each other in an environment with objective-ish judgement of "what is better" instead of "impress the (inevitably corruptible) officials to be judged victorious and awarded the fortunes", and also manually guard and regulate against several universally known ways to sabotage such competition, then we'll be able to channel human ingenuity into solving difficult to solve technical problems while also rewarding those who are able to come up with (and implement) such solutions with low overseeing overhead". Of course, such an attitude isn't strictly speaking "pro-market", it's been around since ancient times; hell, the USSR of all places had this attitude in spades until about the 70s or so.
The second one is "Nah, we don't have to try and think about anything ourselves, just let people fend for themselves, they'll figure it out, and it won't have any unforeseen bad side effects, why would it; markets are magical like that!" Yeah, about that...
Right, a market is a small tool of larger systems. That’s fine, hard to get right but can make systems better. Type two just seems to be the cargo culted everywhere..

Yes, OOP might have chosen a suboptimal example here. But for general newsworthy events, people aren’t going to be in positions to manually make them happen. And no person in a position to start a war would do it to affect a Polymarket bet.
The prediction markets aren't yet at sufficient scale to purchase a war, you mean. People start wars for money all the time though. If they become of sufficient scale, people will purchase wars on them.
There's already lots of examples where they are of sufficient scale, like paying the press secretary to shut up after 64 minutes. Or paying someone to falsify ISWs map of the front line in Ukraine.
> But for general newsworthy events, people aren’t going to be in positions to manually make them happen.
Many newsworthy events (and even more events that actually reach prediction markets, many of which are at best marginally newsworthy) are actions ultimately pivot on a human decision, so the first part isn’t true.
> And no person in a position to start a war would do it to affect a Polymarket bet.
Are you saying “no one would start a war with personal financial gain being part of the motivation”, or “it is impossible for the payoff of a prediction market bet to be of sufficient magnitude to alter the calculus in even the tiniest iota in that case”?
Because the first seems extremely clearly false, and the second seems improbable in the case where the first is false.
> And no person in a position to start a war would do it to affect a Polymarket bet.
No person in position to start a war and to influence economic policies would become a crypto scammer... erm wait...
I can see someone in the Trump admin absolutely using a betting market when they can influence the outcome. At the least I'd also bet that someone in the T admin was the person who knew about Maduro being captured.
...but many people in positions where they can start a war or cause some other highly visible event of any sort probably will start turning to Polymarket to make money in the course of their work
Which makes the prediction market more accurate.

Are you fucking kidding? Based just on current events, that is absolutely not a statement you can make without at least trying to prove it.
If you do try to prove that you will fail as the idea that people would start wars for profit is as old as wars.
Just evaluate the sentence you've just created. How many people exist who have the capability to start wars or influence the start of wars? It's a lot. What else do you know about these people and their motivations?
It isn’t just the people who can start a war. It’s also normal people who can.
Imagine if 10 million people bet on starting a war vs 5 million who say no war. Those net 5 million people are going on social media saying why the war is justified. They’ll vote in war mongers. They’ll support the military. The bet literally influences the result. It’s a self fulfilling prophecy.
It's not a bounty, though, right? It operates like other trading markets? So unless they have big money to wager, they don't have big money to gain. If it's hovering at, say, 10% odds, it's not like they can automatically 10x their money because other people have to take the opposite side. There would have to be a lot of liquidity in the market for their large bet not to move the odds, and as the odds move, they make less money.
> So unless they have big money to wager, they don't have big money to gain.
It requires that they put down collateral (the purchase of the the yes bets) that they lose if they don't meet the contract, so they do have to have starting capital.
> because other people have to take the opposite side.
That is to say that there must be people offering the bounty.
The size of the bounty isn't defined by the price of the contract, but the total upside available in the order book.
> and as the odds move, they make less money.
They have to put up more collateral for the remainder of the contract if they want that upside - but they make all the money that they already put up collateral for.
> The size of the bounty isn't defined by the price of the contract, but the total upside available in the order book.
But one person doesn't get the whole thing. ALL the people holding that side of the contract split the payout, in proportion to the size of their holdings in that side of the market.
I think if I use hypothetical numbers, it will help me explain how I think it works, and maybe this will help someone figure out where my error is.
Let's imagine the market is about whether I will die by the end of the day. So far, there are $500,000 in total bets in the market, and there are 5,000 shares in this market. Let's say it's currently sitting at only 10% odds that I'm going to die. I think that means 4,500 shares, or $450,000, is on the "No" side and 500 shares, or $50,000 is on the "Yes" side. Do I have that right so far?
If nothing changes about the market and I'm still alive at the end of the day, everyone who holds a "No" share splits the $500,000 pot, correct? There are 4,500 of them, so they each get $111.11 per share.
But suppose someone has a solid plan to kill me by the end of the day. They decide they want to dump $50,000 in on the "Yes" side. That's not going to buy them 500 shares, because they would need someone willing to sell 500 shares at the current price. They'll actually get well under 500 shares, and probably not even half that many, and they'll still be splitting the pot among the other people who already have the 500 shares on the "Yes" side. So they're still at not even half the "Yes" side of the market. They can probably double or triple their money, but we're talking about making another $50-100k on top of getting their own $50k back. It's not like they get the whole $500k.
That's what I mean when I say it's "not a bounty." A "bounty" makes it sound like, "If you're the one who kills smeej, you get $500k," but that's not what's happening here.
Lots of people might be willing to try to kill me for $500k. A heck of a lot fewer are going to be willing to try to kill me for 2-3x whatever capital they can come up with right before the hit.
Am I at least understanding this part of it correctly, how the payouts actually work? If I'm not, that would go a long way toward helping me figure out what I'm missing.

Why would the opposing side of that exact same bet allow themselves to be fleeced of all that money for free?
You're asking why someone hiring a hitman would be willing to part with their money?
Because that's what money is for, to purchase things, like hitmen (apparently).
OK so its much a shallower thought than I anticipated.
Why go through the "prediction market" at all then? The hitman still killed someone, payments are not anonymous in this market, and its certainly not clean. Further, you share the pot with however many are involved, proportional to the allotted bets on each side and presuming binary prediction. And if the winds change on the market for the bet proportional to the "hitman's" side, you lose out on dollars that would otherwise be paid to you (the hitman).
And it'd be so easy to stiff the hitman just by equalizing the positions by timing it.
All that risk for something that's far simpler to just pay directly?

The opposing side is getting paid, not getting fleeced.
Asymmetry of information. Fixed bets depend entirely on a small enough group with the ability to influence the outcome, keeping their mouths shut.
