According to the Economist recently [1], Israel recently caught a couple of men who bet on the timing of the Iran attacks last year :

"Last summer one “ricosuave666” won more than $150,000 on Polymarket, a betting platform. Their true identity was not clear, but the source of the winnings was: ricosuave666 had bet, with suspicious accuracy, on the precise timing of Israel’s attacks on Iran."

So, these people can be found. Overall however, the magazine does not think that these markets should have a blanket ban.
