Prediction markets have value for people as a source of reliable information because they tend to be very accurate compared to any other human mechanism for creating forecasts.

Are you talking about the same thing everyone else is?
Imagine the conversation went like this:
A: "Maybe we shouldn't sacrifice 500 virgins to the Aztec God to predict the harvest next hear?"
B "Why not? Killing virgins to predict the harvest are well calibrated (ie accurate).."

I wouldn't be able to say this with a straight face after reading this article.

There is no evidence that people betting on whether Iran will strike Israel on March 15th has any benefit. Who would be the beneficiary of that?
Are you gonna tell me residents in Tel Aviv will be able to hedge their chances of surviving tomorrow?
Nor there's evidence that providing information about the fact that US will strike Venezuela does it either.
What value any of that has? None, especially considering the perverse incentives on the other side of acting on the outcome probability for financial gain which has already happened. US executive insiders have definitely bet on US attacking Venezuela on Polymarket.
You see this as "information discovery", I see it as the fact that I can lobby for dangerous events to happen just for financial gain.
Future markets have some value in some scenarios where you can hedge the outcome.
E.g. a farmer hedging crop prices can de risk his operations.
There is a hedging and the hedge works as insurance.
What's exactly the value of betting on elections or military strikes? What's being hedged?
How can you not see the financial incentives?
We have a long history of regulating both futures, derivatives and betting for very specific reasons.
But now we've relabeled it all as information gathering and price discovery.
How can you not see how the financial incentives here are speedrunning terrible events to happen?
I'm gonna rephrase it like that: would you like for a contract to exist on whether you'll be sent to hospital tomorrow in a crash accident?
Are you gonna tell me: "well, it's information discovery and it's valuable that I can wake up knowing the odds have increased!" while ignoring that there are now people out there financially motivated to make this happen?
