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

The prediction market industry has long maintained that its products are legitimate financial instruments, not merely bets. However, Wisconsin has taken a firm stance against this claim, filing a complaint against Kalshi, Coinbase, Polymarket, Robinhood, and Crypto.com. According to Wisconsin's Attorney General Josh Kaul, 'disguising unlawful conduct as something lawful does not make it so.' The lawsuit centers on the question of whether these platforms offer financial instruments under the purview of the Commodity Futures Trading Commission (CFTC) or if they constitute bets under state gambling laws. This distinction is crucial, as it will determine whether the industry is regulated at the federal level or if it falls under the jurisdiction of individual states. The case is likely to be appealed to the Supreme Court. Wisconsin's complaint targets three distinct ecosystems, naming Crypto.com, Polymarket, and Kalshi, along with 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 payout if they are correct. The complaint cites examples of traders buying contracts tied to NCAA tournament games, which function similarly to traditional bets. Additionally, the state points to the platforms' own marketing materials, 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 contends that the structure of these prediction markets aligns with its definition of a bet, regardless of the label or the counterparty involved. The platforms' revenue model, which involves charging transaction fees on each contract, is also likened to a casino's practice of taking a cut of wagers. The industry's defense relies on federal preemption, with Kalshi arguing that its contracts are regulated swaps under the CFTC's jurisdiction. However, this position has been met with resistance from state courts, which have consistently ruled that such contracts are indistinguishable from gambling. The Wisconsin lawsuit is the latest in a series of state challenges, each contributing to a growing body of evidence that may ultimately compel the Supreme Court to weigh in on the matter.
