Kalshi Faces Class Action Lawsuit Over Khamenei Prediction Market Payout

Prediction markets platform Kalshi is embroiled in legal turmoil after traders disputed payouts tied to a contract on Iran's Supreme Leader Ayatollah Ali Khamenei. The class action lawsuit, filed in California, alleges the platform misled participants by applying a "death carveout" rule following unconfirmed reports of Khamenei's demise.

Plaintiffs claim Kalshi created expectations of full payouts for contracts predicting Khamenei's removal by March 1. When multiple outlets reported his death on February 28, traders expected $1 per "yes" share—the standard correct prediction payout. Instead, Kalshi invoked a clause voiding payouts if leadership changes resulted solely from death.

The case highlights growing pains in prediction markets as they navigate sensitive geopolitical events. Kalshi maintains the rule prevents profiting from mortality events, while traders argue it constitutes contract breach. This legal challenge may set precedents for how platforms structure markets involving high-profile figures.
