Availability is indicative and can change, and individual states may restrict specific products such as sports-event contracts. Confirm the current position with the platform and a qualified professional before acting.
As of May 2026 the position is contested and actively litigated. Montana has asserted that event contracts are illegal gambling under state law and issued cease and desist notices to at least one major operator, which then sued the state in federal court to block enforcement on federal preemption grounds. No final ruling had settled the question. Sports contracts are the most disputed category. This is general information, not legal advice.
Montana, through its attorney general and Gambling Control Division, issued cease and desist notices stating that the activity is illegal gambling under Montana law. Rather than comply, the operator sued the state in federal court in 2026 seeking to block enforcement. The matter was unresolved as of May 2026, so treat the position as contested and confirm the current status before relying on it.
Montana takes the view that paying for a contract on a future event, especially a sports outcome, is functionally a wager that risks money on chance and so falls under state gambling law. The operators argue their contracts are federally regulated derivatives overseen by the Commodity Futures Trading Commission and that federal law preempts state gambling enforcement. That clash is what the courts are deciding. As of May 2026.
Access has rested on the federal preemption argument, which Montana is actively contesting in court, so it could change with little notice. Confirm your own eligibility and the platform current status before acting, and treat sports contracts as the most contested. This is general information, not legal advice, current as of May 2026.
That is the core dispute. Federally registered event contracts are overseen by the Commodity Futures Trading Commission, while Montana asserts its own gambling authority. A federal appeals court ruling in April 2026 leaned toward exclusive federal jurisdiction over sports event contracts, but the question is not finally settled and the Commodity Futures Trading Commission opened a rulemaking in June 2026. Unresolved as of May 2026.
The status above reflects the federal framework and the state position as we read them. These change, so verify the current rules before you act.
