The idea is that prediction markets show the “odds” of an event occurring (that’s why it’s percentages after all).

So if a war with Iran is going to happen, and so a general bets that it will, the odds will jump and go very high.

Now at least theoretically, people in the Middle East can see the high odds, and travel elsewhere.

After seeing how many people got trapped in the UAE, I might check these prediction markets in the future for similar things.
