Wisconsin Takes on Prediction Market Platforms in Lawsuit Against Kalshi, Coinbase, and Others

The prediction market industry consistently maintains that its products are legitimate financial instruments, not mere bets. However, Wisconsin has filed a complaint against Kalshi, Coinbase, Polymarket, Robinhood, and Crypto.com, citing their own marketing materials as evidence that they are operating as unlicensed gambling venues. According to Wisconsin Attorney General Josh Kaul, 'merely disguising unlawful activities does not make them lawful.' The central issue at play is whether these platforms' contracts are financial instruments under the Commodity Futures Trading Commission (CFTC) or if they constitute bets under state gambling laws. This distinction determines whether the market will be regulated by a single federal rulebook or by individual states. The case is likely to be decided by the Supreme Court. Wisconsin's complaints target three separate ecosystems, including Crypto.com, Polymarket, and Kalshi, along with its partners Robinhood and Coinbase. The state argues that the 'event contracts' offered by these platforms are essentially wagers, where users pay to take a position on a real-world outcome and receive a payout if they are correct. The complaints also point to the platforms' revenue models, which involve charging transaction fees, similar to a casino taking a cut of wagers. The industry's defense relies on federal preemption, with Kalshi arguing that its contracts are regulated by the CFTC. However, state courts have consistently taken a different stance, with Nevada and New York characterizing these contracts as indistinguishable from gambling. Wisconsin's lawsuit adds to the growing list of state challenges, which may ultimately require the Supreme Court to decide whether labeling something as a financial contract is sufficient to distinguish it from a bet.
