Synopsis: Coinbase sues Connecticut, Illinois, and Michigan over prediction market regulation, arguing federal CFTC jurisdiction trumps state gambling laws amid Kalshi partnership launch.
Coinbase has launched a bold legal battle against three US states. The crypto exchange filed federal lawsuits on December 19, 2025, targeting Connecticut, Illinois, and Michigan. These states attempted to regulate prediction markets under their gambling laws.
Chief Legal Officer Paul Grewal announced the lawsuits on X, stating the action aims to confirm federal jurisdiction. The move comes just one day after Coinbase revealed plans to integrate prediction markets through partner Kalshi.
Federal Authority Versus State Gaming Laws
Coinbase argues that prediction markets fall exclusively under the Commodity Futures Trading Commission’s jurisdiction. The company filed separate complaints in federal district courts across all three states. Each lawsuit seeks declaratory judgments and injunctive relief to prevent state interference. Grewal emphasized that prediction markets are regulated by the CFTC, not state gaming authorities.
The Illinois filing warns that state intervention could cause “immediate and irreparable” harm to Coinbase’s business operations. Coinbase wants to prevent states from applying gambling laws to federally regulated transactions. The company maintains that Congress excluded only specific items like onions from commodity definitions. Everything else, including event-based contracts, falls within the CFTC’s regulatory scope.
State regulators have taken aggressive actions against prediction market operators in recent weeks. Connecticut issued cease-and-desist orders earlier this month against Kalshi, Robinhood, and Crypto.com. Michigan and Illinois have threatened similar enforcement measures against platforms offering these services. However, states classify event contracts as unauthorized sports betting requiring state oversight.
How Prediction Markets Differ From Traditional Gambling
Grewal stressed that prediction markets function differently from casinos and sportsbooks. Traditional gambling establishments win only when customers lose, setting odds to maximize their profits. Prediction markets operate as neutral exchanges that match buyers with sellers. These platforms remain indifferent to price movements and outcomes.
Users speculate on future events by buying shares in contracts tied to potential results. Markets cover diverse topics including elections, sports matches, and economic indicators. Participants trade based on whether they believe an event will occur or not. Contract prices fluctuate according to market sentiment and collective predictions.
The exchange argues that these markets promote innovation and accurate forecasting. Allowing 50 states to impose different rules would create regulatory chaos. State efforts to control or block these markets stifle innovation and violate federal law. Moreover, Coinbase contends that the most restrictive state could dictate terms nationwide.
Coinbase’s Expansion Into Prediction Markets
The lawsuits arrive one day after Coinbase announced its partnership with Kalshi. This collaboration will bring CFTC-regulated prediction markets to Coinbase users starting January 2026. The initial rollout includes markets in Illinois, with broader US expansion planned afterward. Coinbase customers will access Kalshi’s contracts directly through the Coinbase platform.
Kalshi operates as a designated contract market under CFTC regulation. The platform won a landmark federal court case in 2024 permitting election contracts. Kalshi has faced similar state challenges in Nevada, Maryland, and New Jersey. A federal judge recently granted Kalshi temporary relief, halting Connecticut’s enforcement actions.
Other major players have also entered the prediction market space this year. Robinhood integrated Kalshi’s prediction markets through a non-exclusive partnership. Crypto.com and Gemini are pursuing their own prediction market initiatives. Industry-wide trading volume has surged past $2 billion weekly across major platforms.
Broader Implications For The Industry
This legal battle could establish crucial precedents for prediction market regulation nationwide. Success would clear the path for Coinbase’s Kalshi integration and wider market adoption. Failure might force compliance with 50 different state regulatory regimes, significantly raising operational costs. The outcome will determine whether prediction markets are financial instruments or gambling products.
Conflicting state court rulings could eventually escalate to the US Supreme Court. A Massachusetts decision on similar issues is expected in early 2026. Therefore, analysts view this as a critical test of federalism in emerging financial technology. The cases could influence innovation in decentralized finance and blockchain-based forecasting tools.
Coinbase describes this expansion as a diversification strategy beyond core cryptocurrency trading. The company aims to capitalize on growing demand for event-based speculation. As of December 19, no court dates have been scheduled for these federal cases. Grewal expressed confidence that the law and facts support Coinbase’s position.
