Wisconsin Takes on Prediction Market Giants in Lawsuit

Prediction market operators have long maintained that their products are legitimate financial instruments, not wagers. However, Wisconsin has filed a complaint against several major players, including Kalshi, Coinbase, Polymarket, Robinhood, and Crypto.com, arguing that their marketing materials reveal a different story. According to Wisconsin Attorney General Josh Kaul, 'disguising unlawful conduct as lawful does not make it so.' The lawsuit centers on the question of whether these platforms offer financial contracts or facilitate bets, a distinction that will determine whether they are subject to federal or state regulation. Wisconsin's complaints target three separate ecosystems, citing the companies' own advertising as evidence that they are operating as unlicensed gambling venues. The legal theory behind the complaints is that 'event contracts' are, in fact, wagers, with users paying to take a position on a real-world outcome and receiving a payout if they are correct. The state also points to the platforms' revenue models, which involve charging transaction fees, as 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 Commodity Futures Trading Commission's jurisdiction. However, state courts have consistently taken a different view, with Nevada and New York characterizing the contracts as indistinguishable from gambling. The Wisconsin lawsuit is the latest in a series of state challenges that may ultimately require the Supreme Court to decide whether labeling something a financial contract is enough to exempt it from being treated as a bet.
