So Polymarket would settle the bet based on reporting from a single source? That seems to be very open to manipulation. In fact, for something as inconsequential as this, I'd just bet heavily myself if I were the reporter.
If you can keep the public misinformed for long enough, you can gradually sell off your position instead of losing the whole bet.
And the people taking the other side of the bets. You have to kind of be a fool to take an anonymous bet with an outcome that can more or less be chosen.
There exists a sensible way to handle this. It is to require at least three independent news outlet reports of an event (as defined in the bet).
A related issue is that war news is heavily censored in Israel; it's difficult for news outlets to report it.
Not even that. It is settling a bet on voting. But you are taking a bet on voting on the right side of the outcome. This is independent on the actual bet - this is outcome voting. You make very little money if you vote on correct outcome, and lose a lot if you vote on wrong outcome. So there is an incentive on voting on correct outcome.
