Wisconsin Takes on Prediction Market Giants in Lawsuit

The prediction market industry has long maintained that its products are legitimate financial tools, not mere bets. However, Wisconsin has taken a firm stance against this claim, filing a complaint against several major players, including Kalshi, Coinbase, Polymarket, Robinhood, and Crypto.com. The state's lawsuit argues that these companies are, in fact, operating unlicensed gambling venues, using language from their own marketing materials to support this assertion. According to Attorney General Josh Kaul, 'attempting to disguise unlawful activities does not make them lawful.' The core issue at hand is whether these contracts should be considered financial instruments, subject to federal regulation, or bets, which would fall under state gambling laws. This question has significant implications, as it could determine whether the prediction market industry operates under a single federal rulebook or is instead subject to the jurisdiction of local gaming regulators in each state. Wisconsin's complaints target three distinct ecosystems, naming Crypto.com, Polymarket, and Kalshi, along with its distribution partners Robinhood and Coinbase. The state's legal theory is that the 'event contracts' offered by these platforms are, in essence, 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. State prosecutors also point to the platforms' own advertising, such as 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 state argues that the structure of these prediction markets falls squarely within its definition of a bet, regardless of how the products are labeled or who takes the other side of the trade. Furthermore, the complaints emphasize that these 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 these contracts as indistinguishable from gambling. The Wisconsin lawsuit adds to the growing list of state challenges, building a record that could ultimately force the Supreme Court to decide whether labeling something a financial contract is enough to exempt it from being treated as a bet.
