Kalshi

A court ruling is affecting Kalshi, the prediction market platform that lets users trade contracts on the outcomes of real-world events. The decision is expected to influence how event contracts are regulated and offered, with potential consequences for Kalshi's operations and the wider event-contracts industry. Observers are watching closely for how regulators and the company respond to the ruling.

A federal appeals court for the Sixth Circuit has ruled that Ohio can move ahead with regulating Kalshi's sports event contracts, a decision with implications for the fast-growing market in prediction and event-based trading. The ruling signals that state gambling regulators may have authority over such contracts, a outcome being watched closely by both prediction market platforms and state regulators nationwide.
