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, federally overseen event contract venues operate under Commodity Futures Trading Commission oversight, but Ohio is one of the most active states contesting sports event contracts. The Ohio Casino Control Commission issued a cease and desist over those contracts in 2025, and an operator sued the commission and the state attorney general. A federal judge declined to block the state while the case proceeds on appeal. Treat Ohio as contested and confirm your own eligibility. This is general information, not legal advice.
Yes. The Ohio Casino Control Commission sent a cease and desist to a major prediction market operator in 2025 over sports event contracts and later moved to impose a civil penalty. The operator sued the commission and the Ohio attorney general in federal court. As of May 2026 a district judge had declined to grant the operator a preliminary injunction, and the dispute was before a federal appeals court. This is a dated snapshot.
For federally listed event contracts the relevant regulator is the Commodity Futures Trading Commission at the federal level. Ohio also maintains its own gambling framework, administered by the Ohio Casino Control Commission, which licenses casinos and regulated sports betting and has taken the lead in challenging sports event contracts in the state.
Their status in Ohio is actively contested and in litigation. The Ohio Casino Control Commission treats them as unlicensed sports betting, an operator disputes that and argues federal oversight preempts state law, and as of May 2026 a federal judge had sided with the state at the preliminary stage while the matter is on appeal. Treat sports event contract availability in Ohio as contested and confirm your eligibility. This is general information, not legal advice.
The position on offshore platforms that lack United States registration is contested and carries added risk, including around custody of funds and legal recourse. We mark it as contested rather than giving a definitive answer, and we do not link to such venues. Verify your own position before acting.
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.
