Wisconsin Takes on Prediction Market Giants in Lawsuit

The prediction market industry has consistently maintained that its products are legitimate financial instruments, rather than mere bets. However, Wisconsin has taken a stance against this claim, filing a lawsuit against major players such as Kalshi, Coinbase, Polymarket, Robinhood, and Crypto.com. The state's complaint centers around the marketing language used by these platforms, which Wisconsin claims is indicative of unlicensed gambling operations. Attorney General Josh Kaul emphasized that 'disguising unlawful conduct does not make it lawful.' The lawsuit raises a fundamental question: do these contracts constitute financial instruments under the Commodity Futures Trading Commission (CFTC), or are they simply bets subject to state gambling laws? This distinction will determine whether the rapidly growing prediction market operates under a unified federal rulebook or is instead regulated by individual states. The issue is likely to 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 legal argument is that so-called 'event contracts' 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 state cites examples of traders buying contracts tied to NCAA tournament games, with winning positions paying out $1 and losing ones returning nothing. Wisconsin also points to the platforms' own advertising, such as Kalshi's claim of being 'The First Nationwide Legal Sports Betting Platform' and Polymarket's description as 'a platform where people can bet on the outcome of future events.' The state argues that the structure of prediction markets falls squarely within its definition of a bet, regardless of labeling or the counterparty to the trade. Furthermore, the complaints 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, thus falling under the CFTC's exclusive jurisdiction. However, state courts have consistently taken a different stance, with Nevada and New York characterizing the contracts as indistinguishable from gambling. The Wisconsin 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 sufficient to distinguish it from a bet.
