In wake of the assassination of Ayatollah Ali Khamenei, Iranian Supreme Leader, prediction markets Kalshi and Polymarket saw millions of dollars in contracts traded on his leadership fate.
Kalshi paused a market on Khamenei's status, triggering backlash and accusations of mishandling trades.
Tarek Mansour, Kalshi's chief executive, acknowledged a "death carve-out" rule that affected payouts.
Lawmakers question ethics of betting on such events, with some proposing legislation to ban death contracts.

Polymarket Bets Surge

Polymarket, a prediction market platform, saw betting activity suggesting some bettors anticipated a U.S. and Israeli strike on Iran.
The day before the attack, more than 150 accounts placed bets totaling $855,000 that a U.S. strike would occur by the next day.
The unusually high-stakes betting raised suspicions of insider knowledge about the timing of the military action.
