Wisconsin Takes on Prediction Market Giants in Lawsuit

The state of Wisconsin has filed a complaint against several prominent prediction market platforms, including Kalshi, Coinbase, Polymarket, Robinhood, and Crypto.com, alleging that they are operating as unlicensed gambling venues. According to the complaint, the platforms' marketing materials reveal that their products are essentially bets, rather than financial instruments. Wisconsin's Attorney General, Josh Kaul, stated that "disguising unlawful conduct does not make it lawful." The lawsuit centers on the question of whether the contracts offered by these platforms are financial instruments subject to federal regulation or bets governed by state gaming laws. This distinction will determine whether the prediction market industry will be subject to a single federal regulatory framework or will be regulated by individual states. The case is likely to ultimately be decided by the Supreme Court. Wisconsin's complaints target three separate ecosystems, including Crypto.com, Polymarket, and Kalshi, which partners with Robinhood and Coinbase to offer sports betting to state residents. The state argues that the so-called "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 payout if they are correct. The complaint cites 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." The platforms generate revenue by charging transaction fees on each contract, similar to a casino taking a cut of wagers. 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 characterizing the contracts as indistinguishable from gambling. The Wisconsin lawsuit adds to a growing list of state challenges, which may ultimately force the Supreme Court to decide whether labeling a product as a financial contract is sufficient to exempt it from being treated as a bet.
