Prediction markets let people wager on anything from a basketball game to the outcome of a presidential election — and recently, even the fate of the U.S. and Israel’s war against Iran. Shortly ahead of a fragile ceasefire agreement earlier this week, a new group of accounts on prediction market platform Polymarket made highly specific, well-timed trades betting on a halt in fighting for April 7.
