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 this is actively contested. The Illinois Gaming Board sent cease and desist letters to several prediction market and event contract operators in 2025 and early 2026, asserting they were offering unlicensed sports wagering. The United States and the Commodity Futures Trading Commission then challenged Illinois in federal court, arguing federal law controls. The dispute is unresolved. This is general information, not legal advice.
Yes. The Illinois Gaming Board issued cease and desist letters to operators including a federally registered exchange, a brokerage offering event contracts, and a crypto platform in 2025, and to a further operator in early 2026, stating it had not licensed them for sports wagering. As of May 2026.
Illinois enacted what was reported as the nation first transaction tax on sports event contracts, an exchange wager tax, set to take effect on 1 July 2026. A tax does not by itself settle the separate question of whether the markets are lawful under state gambling law, which remains contested. This is general information, not tax or legal advice, current as of May 2026.
Availability is genuinely uncertain. Federally registered operators have continued to serve users while the federal challenge to Illinois enforcement proceeds, but the underlying legality is unresolved and could change with a ruling. Confirm your own eligibility and the platform current status before acting. This is general information, not legal advice, current as of May 2026.
That is the dispute. The Commodity Futures Trading Commission and the United States argue federal law preempts state gambling enforcement against registered event contract venues, while Illinois asserts its Sports Wagering Act and Criminal Code. Federal courts are deciding. As of May 2026 the question is unresolved.
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.
