The Trump administration has taken a decisive stance in a high-stakes legal confrontation, backing prediction market operators Kalshi and Polymarket as multiple states move to ban their platforms. This intervention by Michael Selig, the newly appointed chairman of the Commodity Futures Trading Commission (CFTC), could reshape the regulatory landscape for sports betting and prediction markets across the United States.
Federal Support in a Contentious Legal Battle
In a significant development, the Trump administration is throwing its weight behind Kalshi and Polymarket in a court fight over whether prediction markets constitute gambling. The CFTC, which currently regulates these markets under federal oversight, allows them to operate in all 50 states, including those where gambling is illegal. However, several states have sued the companies, alleging they run unlicensed casino or gambling operations in violation of state laws and have ordered shutdowns.
CFTC Chairman's Firm Stance
Michael Selig articulated the administration's position in an opinion piece for The Wall Street Journal, stating, "The CFTC will no longer sit idly by while overzealous state governments undermine the agency's exclusive jurisdiction over these markets by seeking to establish statewide prohibitions on these exciting products." This marks a shift from his earlier testimony during his confirmation hearing, where he suggested deferring to courts on the legal issues.
Prediction markets like Kalshi and Polymarket enable participants to buy and sell contracts tied to event outcomes, with customers wagering on diverse topics from weather in Los Angeles to NBA championships or geopolitical conflicts. Contracts are priced between one cent and 99 cents, reflecting the perceived probability of events. Notably, sports betting dominates their trading volumes, with Kalshi reporting over $1 billion in volume for the Superbowl and roughly 90% of its trades sports-related, while Polymarket sees about half tied to sports.
State Lawsuits and Regulatory Clash
The most prominent lawsuit originates from Nevada, where the Nevada Gaming Control Board (NGCB) has taken enforcement actions against Kalshi and Polymarket, accusing them of operating unlicensed sports betting. A federal judge sided with the NGCB, issuing a temporary restraining order against Kalshi in the state. In response, Kalshi has appealed to the U.S. Court of Appeals for the 9th Circuit, prompting the CFTC to weigh in through a "friend of the court" briefing.
Broader Implications for Gambling Regulation
This legal battle could erode states' ability to regulate gambling effectively if Kalshi and Polymarket prevail. States argue that despite offering bets on various future events, the majority of these companies' business is sports betting, and they allow customers as young as 18, unlike state gambling laws that restrict participation to those 21 and older. Selig counters that prediction markets function similarly to other futures contracts, such as those for hedging against weather or energy price changes, and do not involve betting against the house like traditional sportsbooks.
By intervening, the Trump administration is adopting an unusually broad definition of commodities and futures. The CFTC, historically overseeing markets like oil futures, agricultural products, and gold, has expanded its role in recent years, becoming a favored regulator for cryptocurrency firms and prediction market proponents. With about 700 employees, it is significantly smaller than the Securities and Exchange Commission but wields growing influence in financial markets.
Political and Financial Connections
Adding to the controversy, President Trump's son, Donald Trump Jr., has invested in Polymarket through his venture capital firm and served as a strategic advisor for Kalshi. This connection underscores the political dimensions of the dispute. In a video statement, Selig warned challengers, "To those who seek to challenge our authority in this space, let me be clear, we will see you in court," signaling a protracted legal fight ahead.
The outcome of this case could have enormous implications for the prediction market industry and sports betting regulation nationwide, potentially setting a precedent for how emerging financial technologies are governed in the face of state-level opposition.
