Legal battles over U.S. prediction markets intensified as federally regulated exchange Kalshi filed suit in Minnesota and the U.S. Commodity Futures Trading Commission (CFTC) initiated litigation involving Rhode Island. The parallel cases underscore growing friction between federal derivatives oversight and state gambling laws, raising the prospect of appeals that could ultimately reach the U.S. Supreme Court.
State and federal actions escalate
Kalshi filed a lawsuit in Minnesota, challenging state-level actions that it says hinder the operation of federally regulated event contracts for residents. Separately, the CFTC initiated a case involving Rhode Island authorities, signaling that federal regulators may seek to clarify the extent of their jurisdiction over prediction markets when state rules conflict.
Details of the filings were not immediately disclosed. However, the dual actions reflect a broader trend of state agencies and federal regulators testing the boundaries of their respective powers as prediction markets gain traction in the U.S.
Regulatory backdrop: prediction markets in the U.S.
Prediction markets allow users to trade contracts tied to the outcomes of future events, such as elections, economic indicators, or policy decisions. Depending on design and jurisdiction, these products can fall under the CFTC’s authority as event-based derivatives, or be treated by states as gambling. That split has fueled years of disputes involving platforms including PredictIt, Kalshi, and decentralized or offshore services.
The CFTC oversees designated contract markets and swap execution facilities, and has previously scrutinized event contracts it deems to involve “gaming” or to be contrary to the public interest. States, meanwhile, enforce gambling statutes that can restrict or prohibit certain types of wagering, even when offered by federally regulated venues.
Why the outcome matters
How courts resolve the Minnesota and Rhode Island cases could set important precedent on the line between state gambling laws and federally regulated event contracts. A ruling that clarifies federal preemption or the scope of CFTC authority would shape market access for U.S. participants and determine how platforms structure contracts tied to political or economic outcomes.
The decisions may also influence enforcement approaches toward crypto-adjacent and on-chain prediction markets, which have faced prior CFTC actions and typically restrict U.S. users. Clearer rules could affect liquidity, compliance frameworks, and the viability of U.S.-focused offerings in this rapidly evolving segment.
What comes next
Both actions are likely to proceed through preliminary motions that could include requests for temporary restraining orders or injunctions. Given the jurisdictional stakes, appeals are plausible, and legal observers see a path where competing interpretations could bring the issue before the U.S. Supreme Court.
Until courts provide greater clarity, federally supervised event-contract markets and state regulators are expected to continue testing the limits of their respective authorities.
