Are Prediction Markets Legal? The Live State-vs-CFTC Scorecard
One question is being litigated in parallel across American courts: when the CFTC supervises an event-contract market, can a state still call it illegal gambling? Kalshi, Polymarket, Robinhood and Coinbase Financial Markets are all downstream of the answer. This page tracks the cases and what they mean for whether you can actually use these platforms, dated at every step.
Where the question stands
- 10 Jun 2026CFTC proposed rule on event contracts published
- late Jul 2026Federal comment period closed
- 20 Jul 2026Washington preliminary injunction against Kalshi
- late Jul 2026Kalshi appeal filed; stay motion pending
- 13 Aug 2026Washington stay DENIED at both levels; geofencing ordered
- 19 Aug 2026IP and residency-based geofence deadline, met by Kalshi
- 2 Sep 2026Multi-source geofence deadline ($120,000/day fines beyond it) ← current stage
- pending, no dateCFTC final rule
What this means for you, as of 25 August 2026
Nothing in any of these cases targets the individual user: every action so far runs against the platforms. If you hold positions on a platform that loses in your state, the practical risks are account restrictions, forced offboarding and position unwinding on the operator's timetable, not enforcement against you.
In Washington the provisional period is over: since 19 August, Kalshi has been blocking Washington users from sports, elections, politics, entertainment, culture, tech and science, and "mentions" markets under the 13 August geofencing order, and from 2 September the block must work from more than IP address alone. Commodities, climate, economics and finance markets remain available in the state. If you hold Washington positions in a blocked category, expect offboarding and position unwinding on Kalshi's timetable. Elsewhere, availability still differs platform by platform and state by state, and the federal split means neither side can claim the settled answer yet.
We have no commercial relationship with any platform named on this page. This is legal-status tracking, not a recommendation to use any of them.
The question being litigated
Kalshi operates a CFTC-designated exchange and argues that federal commodities oversight preempts state gambling law: if the CFTC supervises the market, a state cannot separately prosecute it as gambling. States reply that an event contract on sports or politics is a bet, whatever the venue registration says, and that gambling regulation has always been state police power. Washington's Judge McHale sided with the state at the preliminary stage; Minnesota's federal court leaned the other way a week later. Utah and Michigan have both since ruled for their states. A CFTC final rule, or an appellate decision, is what eventually collapses this split; until then the answer genuinely differs by courtroom.
Polymarket sits in the same storm at a different angle: its main exchange is offshore and claims to block US users, while a smaller CFTC-approved exchange it acquired serves the US, a dual structure now drawing its own CFTC compliance questions. Robinhood, DraftKings and FanDuel offer event contracts under existing brokerage or wagering frameworks, so a preemption answer reshapes their products too.
Active cases and rulings
| Court | Platform | Status | Leans |
|---|---|---|---|
| Washington (King County Superior Court) | Kalshi v. state enforcement | Preliminary injunction GRANTED against Kalshi on 20 July 2026: Judge John McHale found the platform likely ran an illegal gambling operation under state law, rejecting the CFTC-preemption defence. Kalshi then lost the stay at BOTH levels: a Court of Appeals commissioner denied the emergency stay and McHale declined to pause his own injunction. On 13 August McHale ordered Kalshi to geofence Washington users out of sports, elections, politics, entertainment, culture, tech and science, and "mentions" markets: an IP and residency-based geofence by 19 August (which Kalshi met) and a multi-source geofence by 2 September, on pain of $120,000 a day in fines. Commodities, climate, economics and finance markets remain available. The appeal itself continues. | against preemption |
| Minnesota (federal court) | Kalshi | Order of 27 July 2026 BLOCKED Minnesota from enforcing its prediction-market ban: the federal court leaned toward CFTC jurisdiction. | for preemption |
| Utah (federal court) | Kalshi | Ruling went AGAINST Kalshi: the court held the state can restrict the platform. | against preemption |
| Michigan (federal court) | Coinbase Financial Markets | Ruling of 7 August 2026 REJECTED Coinbase Financial Markets' bid to operate its own prediction market against state objection. | against preemption |
Wisconsin, New York and Illinois have also moved against event-contract platforms through regulators or litigation; those disputes are earlier-stage and join the table when a ruling or formal order is on the record.
Update log
The Washington stay ruling landed against Kalshi at both levels: a Court of Appeals commissioner denied the emergency stay and Judge McHale declined to pause his own injunction. On 13 August McHale ordered Kalshi to geofence Washington users out of sports, elections, politics, entertainment, culture, tech and science, and "mentions" markets, on two deadlines: an IP and residency-based geofence by 19 August, which Kalshi met (Washington users saw the restrictions take effect from 19 to 21 August), and a multi-source geofence by 2 September, carrying $120,000 a day in fines if missed. Commodities, climate, economics and finance markets stay available in the state. The underlying appeal continues, and Kalshi can still ask a full Court of Appeals panel or the Washington Supreme Court to revisit the stay.
Tracker opened. Kalshi remains live in Washington three weeks after the injunction, pending the stay ruling. Neal Katyal, former US Acting Solicitor General, is now lead national counsel for Kalshi across its state cases, a signal the company is positioning the preemption question for higher courts.
Michigan federal court rejected Coinbase Financial Markets. The federal-court split now runs at least three ways across Minnesota, Utah and Michigan.
Minnesota federal court blocked that state from enforcing its prediction-market ban, the strongest ruling so far for the preemption side.
Washington preliminary injunction granted against Kalshi (Attorney General Nick Brown). The core holding: federal commodities oversight does not, at this stage, override state gambling law.
CFTC published a proposed rule for event-contract markets with a 45-day comment period: most sports event contracts would be permissible, with bans on manipulation-prone and violence-linked contracts. A final rule would reshape every state case.
This tracker is updated as rulings land; entries are append-only and corrections are made as dated entries, never silent rewrites. Next scheduled review: 2 September 2026, the Washington multi-source geofence deadline, earlier if an appellate ruling arrives first.
