A Kalshi spokesperson says the platform won’t offer a market predicting whether the Supreme Court will hear a case regarding sports prediction markets or a market on the decision in that case.

The prediction market company has offered wagers tied to athlete health throughout 2026 and had leaned further into those markets until a U-turn.

Kalshi, the most popular prediction market in the U.S., allows users to place yes-or-no bets on future events.
