Rhode Island moved from open to active federal litigation in May 2026 when AG Peter F. Neronha filed parallel state-court suits against Kalshi and Polymarket on May 26, Kalshi filed a federal preemption counter-suit the same day, and the CFTC filed its own federal complaint against Rhode Island on May 29. Rhode Island is now the sixth state in active CFTC vs state preemption litigation alongside Arizona, Illinois, Connecticut, New York, and Minnesota. All platforms remain accessible to Rhode Island residents while the cases proceed. The state's 5.99% top income tax applies to any pre-ruling gains as ordinary income.

The CFTC has now sued Rhode Island. Three federal-vs-state cases on the docket.

The original Wisconsin pattern (state AG sues platforms, platform counter-sues in federal court) escalated quickly here: Neronha's May 26 state suits drew Kalshi's federal preemption complaint the same day, and the CFTC filed its own federal complaint against Rhode Island on May 29 plus a motion to intervene in Kalshi's case. Chairman Michael Selig called the wave of state lawsuits an "onslaught" and a "power grab." Neronha is still seeking disgorgement of platform profits attributable to RI users plus a permanent injunction; sports-betting tax is Rhode Island's third-largest revenue stream. Kalshi's and the CFTC's federal complaints lead with the same Commodity Exchange Act preemption argument that produced a preliminary injunction in Arizona on May 5 before Judge Liburdi.

Which platforms work in Rhode Island?


Every platform is currently accessible. The Neronha suits target sports event contracts specifically, not the broader category of political, economic, or weather markets. If the state court rules against the platforms before the federal court grants Kalshi's preliminary injunction, sports contracts could be the first to be pulled from RI users. Non-sports markets are not directly at risk in this round of litigation.

What Neronha's suit actually demands


The state-court complaints ask for three findings in addition to the disgorgement and injunction remedies: that sports event contracts are "gambling" requiring a constitutional voter referendum, that they are "casino gaming" subject to RILOT operational control, and that they are "online sports wagering" subject to the same regulatory regime as licensed sportsbooks. Each finding is independently sufficient to take Kalshi and Polymarket sports contracts off the Rhode Island market. The constitutional-referendum angle is the most aggressive: it would mean the platforms cannot operate in RI even with a state license, only with a voter-approved amendment.

Kalshi's federal complaint counters with the standard preemption frame: the Commodity Exchange Act grants the CFTC exclusive jurisdiction over derivatives listed on a Designated Contract Market, and a state cannot prohibit conduct that federal law authorizes. The same argument won three independent grounds of preemption (field, conflict, impossibility) in Arizona on May 5. The District of Rhode Island sits in the First Circuit, which has historically taken a broad view of federal preemption in financial-regulation cases.

Our read: Kalshi's federal suit is well-positioned. The Liburdi reasoning is persuasive, the First Circuit is preemption-friendly, and the CFTC will almost certainly intervene or file a separate parallel complaint within weeks. The wrinkle is Neronha's disgorgement demand: if the state court reaches the merits before the federal court grants an injunction, even a partial state win could trigger a money-judgment exposure that the federal preemption ruling cannot fully unwind. Plan around the litigation pace, not the legal merits.
