The Commodity Futures Trading Commission (CFTC) has filed for a preliminary injunction with the U.S. District Court for the District of Minnesota to block enforcement of the state's prediction market ban. According to Reason, this follows after Arizona, Connecticut, Illinois, New Jersey, Massachusetts, and Wisconsin pursued legal action against prediction markets, with the CFTC countersuing and arguing that the Commodity Exchange Act gives it 'exclusive jurisdiction' to regulate financial markets, including prediction markets. The CFTC has also filed amicus briefs in the U.S. Court of Appeals for the 9th Circuit and the Supreme Judicial Court of Massachusetts in support of prediction markets. CFTC Chairman Michael Selig states the law 'turns lawful operators and participants in prediction markets into felons overnight', as under the law's prohibition on promoting transactions, a Minnesota resident who 'advertises or markets' the use of prediction markets, even to non-Minnesota residents, could be charged with a felony. The law would also turn proprietors of legitimate businesses, such as age- and ID-verification sites, into felons for contracting with prediction markets.
On April 23, 2026, the U.S. Attorney's Office for the Southern District of New York and the Commodity Futures Trading Commission announced parallel criminal and civil enforcement actions against an active-duty U.S. Army servicemember in what appears to be the first insider trading case involving prediction markets. Gannon Ken Van Dyke is charged with using classified military information concerning a U.S. military operation to capture then–Venezuelan President Nicolás Maduro to place profitable trades on Polymarket, a prediction market platform. The case, United States v. Gannon Ken Van Dyke, represents the first application of insider trading principles to prediction markets and may provide guidance regarding the types of misappropriated information and trading activity that can support criminal and civil enforcement actions. According to Sidley, this litigation is likely to test the boundaries of the CEA's treatment of event contracts and the application of misappropriation-based fraud theories to prediction market trading.
Minnesota has become the first state in the nation to enact a law banning prediction market platforms, marking a significant escalation in the ongoing legal battle between federal and state regulators. Gov. Tim Walz (D) signed legislation that makes it a crime to host or advertise prediction market services in the state, directly targeting platforms such as Kalshi and Polymarket. Elisabeth Diana, head of communications at Kalshi, tells Reason that 'Minnesota's law is unconstitutional' and that instead of regulated platforms like Kalshi, Polymarket, and Robinhood, the state's law would force consumers to use 'unregulated offshore markets where there are no consumer protections'. A spokesperson for Polymarket also called into question Minnesota's standing to issue a ban, stating the state's action 'runs counter to the federal government's established framework for regulating prediction markets as evidenced by the lawsuit from the CFTC'. State Sen. John Marty (D–Roseville), the bill's author, might have given away the game when he cited dramatic cuts 'into the revenue of Minnesota's regulated gambling' as reasons for banning platforms like Kalshi and Polymarket. The law's definition is broad enough that it could potentially include participation in systems like the Iowa Electronic Markets model, an online futures market that pays out contracts on events banned under the law, such as political outcomes.
Under CFTC Chairman Michael Selig's leadership, the agency has released an advanced notice of proposed rulemaking to guide exchanges on listing prediction market contracts as part of its effort to establish itself as the primary regulator across the prediction markets industry. The May 21 NHL agreement represents the latest move by the CFTC to embed itself as the primary regulator across the prediction markets industry, with the agency moving quickly to establish direct formal relationships with professional sports organizations as event contract volumes continue to grow. Senior enforcement officials have signaled that insider trading laws apply equally to prediction markets and that civil and criminal enforcement authorities intend to pursue misconduct in that space aggressively. At a February 5 forum hosted by Securities Docket, U.S. Attorney for the SDNY Jay Clayton responded to an audience member's question about prediction market prosecutions by stating, 'Yes,' and gave an example of conspiring to fix a golf game through prediction markets, emphasizing 'That's a crime,' and 'Because it's a prediction market doesn't insulate you from fraud.' CFTC Enforcement Director David Miller has also made clear that the agency will pursue misconduct in the prediction market space, with the parallel enforcement actions against Van Dyke demonstrating this commitment.
Prediction markets have evolved into a multi-billion-dollar industry with billions in weekly trading volume, representing a fourfold growth from previous levels. These markets have demonstrated significant performance advantages in economic forecasting, with Kalshi's real-time data being called a 'rich benchmark' by the Federal Reserve for tracking economic expectations. Ford's internal prediction markets have reportedly outperformed expert forecasts with a 25% lower error rate in vehicle sales forecasting, according to Dylan Dewdney, CEO of Kuvi.ai. The performance gap highlights the practical value of prediction markets as operational risk management tools for major corporations, with Cathie Woods from Ark Invest noting that prediction markets are emerging as a powerful new layer of financial infrastructure enabling real-time price discovery around events, probabilities, and the evolving state of the world.
Polymarket has secured exclusive partnerships with major financial institutions including Nasdaq Private Market, New York Stock Exchange (NYSE), Yahoo Finance, and Google, allowing users to trade on pre-IPO firm outcomes such as valuation and IPO timelines. According to AMBCrypto, these institutional arrangements have cemented prediction markets as a new financial infrastructure layer beyond retail betting. Jeff Park from Bitwise emphasized that institutional participation through structured products is essential for improving prediction accuracy by boosting institutional liquidity flow, while Ivan Patriki from QuantMap noted that reliability as forecasting tools can only improve with better liquidity depth. Cathie Woods from Ark Invest made a similar framing after a recent funding round for Kalshi, stating that whoever wins institutional partnerships will cement a massive moat in the prediction market space.
Despite their growth, prediction markets face significant regulatory challenges as sports and politics dominate open interest by nearly $900 million, while economics and financials categories rank fifth and seventh respectively. Minnesota's new law defines prediction markets broadly as systems that allow consumers to place wagers on future outcomes, including sports contests, elections, live entertainment, 'someone's word choice' and world affairs. The law also targets supporting technologies such as virtual private networks that users could employ to evade geolocation restrictions, with violations exposing operators to felony charges. Kalshi spokeswoman Elisabeth Diana called Minnesota's law a 'blatant violation' of federal law and compared banning prediction markets to 'trying to ban the New York Stock Exchange.' The divergent court rulings across states create regulatory uncertainty that could fragment liquidity or potentially ban prediction markets entirely, threatening the institutional adoption that could accelerate mainstream adoption. According to the state's Sentencing Guidelines Commission, anyone found guilty of violating the ban on prediction markets could receive probation, up to a year in jail, or 'other non-jail sanctions', with the law failing to identify a victim as prediction markets do nothing more than facilitate transactions between willing consumers.
