Wisconsin Takes on Prediction Market Giants in Lawsuit

The prediction market industry has long maintained that its products are legitimate financial instruments, not mere betting mechanisms. However, Wisconsin has taken a firm stance against this claim, filing a lawsuit against major players Kalshi, Coinbase, Polymarket, Robinhood, and Crypto.com. The state's complaint centers around the marketing language used by these platforms, which Wisconsin alleges is tantamount to promoting unlicensed gambling. According to Attorney General Josh Kaul, 'masquerading as something lawful does not make it so.' The lawsuit raises a fundamental question: do these contracts constitute financial instruments under the purview of the Commodity Futures Trading Commission (CFTC), or are they, in fact, bets subject to state gaming regulations? This 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 state's legal argument is that the so-called '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 complaints cite examples of traders buying contracts tied to NCAA tournament games, with winning positions paying out $1 and losing ones returning nothing. Furthermore, state prosecutors point to Kalshi's Instagram ads, which describe the platform as 'The First Nationwide Legal Sports Betting Platform,' and Polymarket's ads, which refer to itself 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 statutory definition of a bet, regardless of labeling or who takes the other side of the trade. Additionally, the complaints highlight that platforms generate revenue by charging transaction fees on each contract, similar to a casino taking a cut of wagers placed on its floor. The industry's defense relies on federal preemption, with Kalshi arguing that its contracts are swaps listed on a regulated exchange, thereby falling under the CFTC's exclusive jurisdiction. This position was recently bolstered by a Third Circuit ruling, which treated the regulator's decision not to block the contracts as effectively settling the jurisdictional question. Nevertheless, state courts across the U.S. have consistently taken a different stance, with Nevada and New York both characterizing the contracts as indistinguishable from gambling. The Wisconsin lawsuit is the latest in a growing list of state challenges, each contributing to a record that may ultimately compel the Supreme Court to decide whether labeling something a financial contract is sufficient to distinguish it from a bet.
