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.
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?
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.

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.
No person in position to start a war and to influence economic policies would become a crypto scammer... erm wait...
Causing real world problems with prediction markets would probably be about ego and trolling.
I also find a clear political bias in the naming of some of the markets, but that could be simply because of the demography of the user base.
