Wisconsin Takes on Prediction Market Giants in Lawsuit

The prediction market industry has long maintained that its products are legitimate financial instruments, not simply bets. However, Wisconsin has taken a different stance, filing a lawsuit against several major players, including Kalshi, Coinbase, Polymarket, Robinhood, and Crypto.com. The state's complaint centers on the language used by these platforms, which Wisconsin argues is more akin to gambling than investing. According to Wisconsin Attorney General Josh Kaul, 'attempting to disguise unlawful activities does not make them lawful.' The lawsuit raises a fundamental question: are prediction market contracts financial instruments subject to federal regulation, or are they bets governed by state law? This distinction is crucial, as it determines whether the industry will be subject to a single federal regulatory framework or will be carved up into 50 separate state jurisdictions. The issue is likely to ultimately be decided by the Supreme Court. Wisconsin's complaints target three distinct ecosystems, naming Crypto.com, Polymarket, and Kalshi, along with its distribution partners Robinhood and Coinbase. The state argues that the 'event contracts' offered by these platforms are, in fact, wagers, where users pay to take a position on a real-world outcome and receive a fixed payout if they are correct. The complaints cite examples of traders buying contracts tied to NCAA tournament games, with winning positions paying out $1 and losing ones returning nothing. The state also points to the platforms' own marketing materials, 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.' Wisconsin argues that the structure of prediction markets falls squarely within its statutory definition of a bet, regardless of how the products are labeled or who takes the other side of the trade. The complaints also highlight the fact that platforms generate revenue by charging transaction fees on each contract, similar to a casino taking a cut of wagers placed on its floor. The industry's defense relies on federal preemption, with Kalshi arguing that its contracts are swaps listed on a regulated exchange and therefore fall under the exclusive jurisdiction of the Commodity Futures Trading Commission (CFTC). However, state courts have consistently taken a different position, with Nevada and New York both characterizing the contracts as indistinguishable from gambling. Wisconsin's lawsuit adds to the growing list of state challenges, building a record that could ultimately force the Supreme Court to decide whether calling something a financial contract is enough to keep it from being treated as a bet.
