Summary

An Ohio federal judge denied Kalshi’s request for a preliminary injunction against state sports betting enforcement on March 11. Judge Sarah D. Morrison said there was no evidence Congress intended federal law to preempt state sports betting rules. The ruling adds to the legal dispute over whether prediction market platforms can operate outside state gambling restrictions. Kalshi said it will appeal the decision, a step that could prolong scrutiny of how U.S. courts and regulators treat platforms such as Polymarket.

Terms & Concepts
  • Prediction market: A platform where users trade contracts tied to the outcome of future events, with prices reflecting market-implied probabilities.
  • Preempt: In law, this means federal law overrides or displaces state law when Congress clearly intended that result.
  • Kalshi: A U.S. prediction market platform that offers event contracts and has been involved in legal disputes over the boundary between derivatives regulation and gambling laws.
