On December 18, Coinbase filed lawsuits against Michigan, Illinois, and Connecticut, asserting that these states are overstepping their authority by attempting to regulate prediction markets, which Coinbase argues are under the jurisdiction of the Commodity Futures Trading Commission (CFTC) according to federal law. Coinbase’s Chief Legal Officer, Paul Grewal, made the details of the Illinois case public through social media, highlighting that the states have either taken action or threatened to act against operators without proper legal backing.
The lawsuits aim to establish a clear legal boundary, ensuring that state gaming boards do not interfere with exchanges that are federally registered. This legal maneuver by Coinbase coincides with its upcoming foray into the prediction market sector. The company has announced a partnership with Kalshi, a CFTC-regulated platform, to launch event-based contract trading for U.S. customers in January 2026, including in Illinois. Grewal emphasized the necessity of these lawsuits to resolve what Coinbase sees as a straightforward legal issue: prediction markets fall under the CFTC’s jurisdiction, not that of individual states. He further argued that state attempts to regulate these markets stifle innovation and contravene federal law.
In Illinois, Coinbase warned that state interference could cause “immediate and irreparable” damage to its business operations. The company is seeking both declaratory and injunctive relief to halt enforcement actions pending court decisions. At the heart of this dispute is the classification of prediction markets. Some states believe that contracts related to outcomes of events, such as sports, qualify as unlicensed betting, thus falling under state gambling laws. However, Coinbase and similar operators argue that these markets are neutral exchanges facilitating transactions between buyers and sellers, not sportsbooks setting odds for profit.
Grewal pointed to the Congressional definition of commodities, which specifically excludes only a limited set of items, thereby affirming that sports-related event contracts fall within the CFTC’s oversight. He articulated that excluding such contracts from CFTC oversight would defy the logic of the commodities definition laid out by Congress.
The legal conflict has now widened, involving ten states. Initially sparked by cease and desist orders from a handful of regulators, the dispute has expanded with Illinois and Michigan joining the fray following Coinbase’s latest legal actions. Connecticut is already engaged in litigation with Kalshi, and other states involved include Maryland, New Jersey, Ohio, Nevada, Massachusetts, and New York. The issue extends beyond state regulators as Native American tribes in California and Wisconsin have also initiated lawsuits against prediction market operators.
Coinbase cautions that if individual states are allowed to regulate these markets independently, it could result in a fragmented system that opposes Congress’s intent. The company argues that allowing states like Illinois to infringe on CFTC jurisdiction would undermine Congress’s objective of ensuring uniformity in the futures market nationwide.
Amidst this backdrop, experts in the industry are divided. Some argue that state regulation is necessary to protect consumers and ensure fair market practices. They contend that without state oversight, consumers could be exposed to unregulated risks. Others, however, agree with Coinbase’s position, suggesting that a cohesive federal regulatory framework is essential for fostering innovation and maintaining consistent market operations across the country.
As the legal battle unfolds, it highlights the broader tension between federal and state regulatory powers in the rapidly evolving landscape of prediction markets. The outcomes of these lawsuits could have significant implications for the future of online trading platforms and their regulation, potentially setting a precedent for how similar disputes are handled in the future.
While Coinbase remains determined to assert its position, the path forward is uncertain. The courts’ decisions will not only impact Coinbase’s business strategy but may also influence how other companies approach prediction markets and their regulatory environments. As the industry continues to grow and innovate, the resolution of this legal conflict could shape the future of prediction markets in the U.S., setting the stage for a new era in online trading.
