The federal-vs-state fight

Every entry in this fight turns on the same question: does a prediction-market platform's federal regulation by the CFTC preempt a state's gambling law, or does the state retain authority to restrict it? Courts around the country are answering that question differently — sometimes for the platform, sometimes for the state — and almost every ruling so far is preliminary and under appeal. Treat this page as a snapshot, not a final word.
