Is Kalshi legal in Rhode Island right now?

Yes, in the practical sense: Kalshi and Polymarket are both accessible in Rhode Island and no court has ordered either to stop. Unlike Massachusetts, Michigan, Nevada or Washington, there is no injunction in force. What exists instead is three sets of live litigation pointing in different directions, none of which has produced a ruling.

Did Rhode Island sue Polymarket as well as Kalshi?

Yes, and that is unusual. Most state actions have named Kalshi alone. Attorney General Peter Neronha's Superior Court complaint of 21 May 2026 named both operators, which makes Rhode Island one of the few places where Polymarket is a direct defendant in a state gambling case.

Why is the CFTC suing a state attorney general?

The Commodity Futures Trading Commission takes the position that the Commodity Exchange Act gives it exclusive jurisdiction over event contracts, and that a state enforcement threat against a federally registered exchange is preempted. It filed against the Rhode Island Attorney General on 28 May 2026, a week after the state's own suit.

How much does Rhode Island make from sports betting?

Under state law the split on online sports betting revenue is 51% to the state, 32% to the online operator and 17% to Bally's retail sportsbook. That 51% is the highest state share in the country, and it is the revenue line the Attorney General's complaint is defending.

When will this be decided?

There is no scheduled decision. All three cases were filed in May 2026 and none had produced a ruling as of 25 August 2026. Rhode Island is not among the states with an appellate decision pending, so it is likely to be shaped by rulings elsewhere before it is resolved on its own facts.

Is Kalshi legal in Rhode Island?

Explainer · Updated August 25, 2026 · 18+ · Not legal advice · By BetG8 Editorial · Prediction Markets

Short answer: yes, for now. Kalshi and Polymarket both operate in Rhode Island and no court has ordered either to stop. There is no injunction here, unlike Massachusetts, Michigan, Nevada or Washington. What Rhode Island has instead is three lawsuits filed within eight days of each other in May 2026 — the state against both operators, Kalshi against the state, and the federal regulator against the state’s Attorney General — and not one of them has produced a ruling.

The timeline

Date	What happened
2019	Rhode Island launches online sports betting through a single state-contracted platform, run as a lottery monopoly rather than an open commercial market.
May 8, 2026	The Rhode Island Lottery tentatively awards Bally’s a five-year deal to run the state’s second online sportsbook, ending the one-operator market. DraftKings and FanDuel did not apply.
May 21, 2026	Duelling filings on the same day. Kalshi sues Rhode Island pre-emptively in the U.S. District Court for the District of Rhode Island. Hours later Attorney General Peter Neronha sues Kalshi and Polymarket in Rhode Island Superior Court, alleging their sports event contracts are unlicensed gambling.
May 26, 2026	The Bally’s award is reported publicly, five days after the state sued the prediction markets it says are taking that market’s revenue.
May 28, 2026	The CFTC sues the Rhode Island Attorney General, arguing the Commodity Exchange Act gives it exclusive jurisdiction and that the state’s enforcement threat is preempted.
August 25, 2026	No ruling in any of the three cases. Both platforms remain available in the state.

Why Rhode Island is a different kind of case

Most states fighting prediction markets are protecting a commercial sportsbook industry that pays tax. Rhode Island is protecting something more direct: it is the operator’s partner. Under state law, online sports betting revenue splits 51% to the state, 32% to the online platform and 17% to Bally’s retail sportsbook in Lincoln. That 51% is the largest state share in the United States. When Rhode Island argues that event contracts erode its gambling revenue, it is not making an abstract policy point about consumer protection. It is describing its own budget line.

The Attorney General has been unusually blunt about the substance. In announcing the suit, Peter Neronha said there is no substantive difference between sports betting and event contracts in this context, and that both operators know it. That framing — function over form — is the same argument New York, Nevada and Washington have made, but Rhode Island paired it with a number: its complaint states that sports wagers in the state fell 8% from 2024 to 2025.

Rhode Island is also one of the few states to name Polymarket as a defendant alongside Kalshi. Most state actions have gone after Kalshi alone, largely because Kalshi is the CFTC-registered exchange with a US retail footprint to enjoin. Naming both widens the question from “is this exchange preempted” to “is this activity gambling”.

The awkward part of the state’s own position

Five days after suing over lost gambling revenue, Rhode Island confirmed it had picked Bally’s to run a second online sportsbook — a licence that DraftKings and FanDuel, the two largest operators in the country, declined to bid for. Industry analysis of the state’s terms had already flagged limited vendor interest because of the tax structure; DraftKings indicated the commercial terms would not have let it compete effectively.

That is a genuine tension in the record, and it is worth stating plainly rather than scoring a point off it. Rhode Island’s position is that prediction markets are draining a regulated market. The counter-observation is that the state set terms severe enough that the largest regulated operators walked away from them before Kalshi was a meaningful factor. Both things can be true at once, and neither settles the legal question, which is about preemption rather than pricing.

Where Rhode Island sits in the national picture

Rhode Island belongs to the group of states that have acted but not yet won anything. It has no injunction, no appellate ruling and no compliance deadline. Compare that with the states where something is actually in force:

State	Status	Detail
Rhode Island	Litigation, no order	Three suits filed May 2026, no ruling. Both platforms operating.
Washington	Order in force	Staged geofencing deadlines, with a daily penalty attached to the September date.
Utah	Final judgment	First final federal judgment that a state may apply its gambling laws. On appeal.
New Jersey	Enforcement blocked	Third Circuit held the federal statute likely preempts state law.
Minnesota	Ban enjoined	The only felony ban in the country was blocked before it took effect.

The practical consequence is that Rhode Island is unlikely to be decided on its own facts first. The preemption question it turns on is already before the Sixth, Ninth and Tenth Circuits. Whichever of those lands first will shape what the District of Rhode Island does with Kalshi’s case, and what weight the Superior Court gives the state’s.

What this means if you are in Rhode Island

Nothing has been switched off. Both platforms are reachable, positions can be opened and closed, and no court has told either operator to geofence the state. That is the factual position as of 25 August 2026 and it can change on any docket day, in either direction — a state win would bring an order, a Kalshi win would bring an injunction against the state.
