Wisconsin Takes on Prediction Market Giants in Lawsuit

The prediction market industry has consistently maintained that its products are legitimate financial instruments, rather than bets. However, Wisconsin has taken a different stance, filing a lawsuit against several major players in the industry, including Kalshi, Coinbase, Polymarket, Robinhood, and Crypto.com. The state's complaint argues that the marketing language used by these platforms is more akin to gambling than investing. According to Wisconsin Attorney General Josh Kaul, 'disguising unlawful conduct as lawful does not make it so.' The lawsuit raises a fundamental question: are these contracts legitimate financial instruments under the jurisdiction of the Commodity Futures Trading Commission (CFTC), or are they simply bets that fall under state gambling laws? This question has significant implications, as it will determine whether the prediction market industry operates under a single federal regulatory framework or is subject to a patchwork of state laws. The issue is likely to ultimately be decided by the Supreme Court. Wisconsin's lawsuit targets three separate ecosystems, including Crypto.com and its derivatives arm, Polymarket and its affiliated entities, and Kalshi, which partners with Robinhood and Coinbase to offer prediction market contracts to state residents. The state's legal theory is that the 'event contracts' offered by these platforms are, in fact, wagers, in which users pay money to take a position on a real-world outcome and receive a fixed payout if they are correct. The lawsuit cites examples of contracts tied to NCAA tournament games, in which traders could buy contracts at prices that reflect implied probabilities, with winning positions paying out $1 and losing ones returning nothing. The state also points to the marketing language used by these platforms, including Kalshi's claim to be 'The First Nationwide Legal Sports Betting Platform' and Polymarket's description of itself as 'a platform where people can bet on the outcome of future events.' The lawsuit argues that the structure of prediction markets falls squarely within the state's definition of a bet, regardless of how the products are labeled or who takes the other side of the trade. The complaint also notes that the platforms generate revenue by charging transaction fees on each contract, which is similar to a casino taking a cut of wagers placed on its floor. The industry's defense is based on federal preemption, with Kalshi arguing that its contracts are swaps listed on a regulated exchange and therefore fall under the CFTC's exclusive jurisdiction. However, state courts have consistently taken a different position, with Nevada and New York both characterizing the contracts as indistinguishable from gambling. The Wisconsin lawsuit is the latest in a growing list of state challenges to the prediction market industry, and it is likely to contribute to a record that will ultimately be decided by the Supreme Court.
