Rhode Island Attorney General Challenges Prediction Markets Over Sports Event Contracts

Attorney General Peter Neronha filed a lawsuit in Providence County Superior Court that names Kalshi and Polymarket as defendants, and the complaint centers on claims these platforms offer sports betting to Rhode Island residents through event contracts that fall outside the state's licensed system. The filing states that the platforms structure wagers on athletic outcomes as prediction contracts, which directs revenue away from the single state-sponsored sports betting operator that receives all regulated activity under current law.

State officials maintain that Rhode Island law requires sports betting to route through this designated platform so tax revenue and oversight remain centralized. The complaint argues that Kalshi and Polymarket's product design effectively replicates traditional sports wagering while avoiding those requirements, and it seeks injunctive relief plus civil penalties for each alleged violation.

Sequence of Court Actions

Kalshi initiated its own proceeding in federal court several hours before the state filing became public, and that complaint asks a judge to prevent Rhode Island from enforcing its gambling statutes against the platform. Kalshi's argument rests on the assertion that the Commodity Futures Trading Commission holds primary jurisdiction over event contracts, which places the matter under federal rather than state authority.

The timing of the two suits created an immediate jurisdictional question that both sides will litigate in the coming months. Observers note that similar disputes have arisen in other states where prediction platforms expanded into sports-related contracts, yet the Rhode Island case marks the first time a state attorney general has paired an enforcement action with a preemptive federal challenge from one of the named platforms.

Regulatory Framework at Issue

Rhode Island operates under statutes that grant exclusive rights for sports betting to a single operator, and that structure channels all wagers through a controlled system that collects taxes and maintains consumer protections. The attorney general's office contends that event contracts on athletic results constitute sports betting regardless of how the platforms label the products, and therefore they must comply with the same licensing and revenue-sharing rules.

Data from the state's regulated market shows consistent tax collections that support public programs, and any volume moving to unlicensed platforms reduces those receipts. The complaint references specific contracts offered on Kalshi and Polymarket that mirror common sports wagers such as game winners and point spreads, while the platforms classify them as binary outcome contracts tied to verifiable events.

Arguments Presented by Each Side

The state's position emphasizes consumer protection and revenue integrity, stating that residents who place sports wagers on the named platforms lack the safeguards built into the licensed system. Neronha's office further claims that the platforms actively market to Rhode Island users through mobile applications and websites, which establishes sufficient contacts for state enforcement.

Kalshi's federal filing counters that its contracts fall under CFTC oversight through existing no-action letters and regulatory guidance on event contracts, and it asserts that state-level interference would create conflicting regulatory regimes. The company seeks declaratory judgment that Rhode Island cannot apply its gambling laws to these products, and it argues that federal preemption principles shield the platform from the state lawsuit.

Polymarket has not yet filed a parallel federal action, though its platform offers comparable contracts on professional and college sports outcomes. Both companies maintain that their products differ from traditional sportsbooks because they settle based on objective data rather than bookmaker odds, yet the attorney general's complaint treats that distinction as irrelevant under Rhode Island statute.

Potential Next Steps in Litigation

The dual filings place the dispute on parallel tracks, with the state case proceeding in superior court while the federal matter addresses preemption and jurisdiction. Hearings on preliminary injunction requests could occur within weeks, and any ruling would likely address whether event contracts constitute gambling under state law or fall exclusively within federal derivatives regulation.

Legal analysts tracking similar cases note that courts have reached differing conclusions on the scope of CFTC authority versus state gambling enforcement, and the Rhode Island litigation adds another data point to that developing body of law. The attorney general's office indicated it will seek expedited discovery to document the volume of Rhode Island-based activity on both platforms.

Conclusion

The lawsuit and the preemptive federal action together highlight the ongoing tension between state-controlled sports betting markets and federally regulated prediction platforms that offer contracts on athletic events. Proceedings in both Providence County Superior Court and federal district court will determine whether Rhode Island can enforce its licensing requirements or whether federal oversight displaces those rules for the named products. Further filings are expected as the parties exchange motions and evidence in the weeks ahead.
