Wisconsin Takes on Prediction Market Giants in Lawsuit

The prediction market industry has long maintained that its products are legitimate financial instruments, not mere bets. However, Wisconsin has taken a firm stance against this claim, filing a lawsuit against major players Kalshi, Coinbase, Polymarket, Robinhood, and Crypto.com. 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 classified as financial instruments under the Commodity Futures Trading Commission (CFTC) or as bets under state gambling laws. This distinction will determine whether the rapidly growing market will be subject to federal regulations or state-specific gaming laws. The case is likely to eventually be heard by the Supreme Court. Wisconsin's complaints, filed in Dane County, target three distinct ecosystems: one involving Crypto.com and its derivatives arm, another targeting Polymarket and affiliated entities, and a third involving Kalshi and its distribution partners Robinhood and Coinbase. The state argues 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 lawsuit cites 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 marketing materials, such as Kalshi's Instagram ads claiming 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 contends that the structure of prediction markets falls squarely within its definition of a bet, regardless of labeling or who takes the other side of the trade. The complaints also highlight that 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 CFTC's exclusive jurisdiction. However, state courts have consistently taken a different stance, 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 may ultimately force the Supreme Court to decide whether labeling something a financial contract is enough to exempt it from being treated as a bet.
