Wisconsin Takes on Prediction Market Giants in Lawsuit

The prediction market industry has long maintained that its products are legitimate financial tools, not mere bets. However, Wisconsin has taken a firm stance against this claim, filing a lawsuit against several major players, including Kalshi, Coinbase, Polymarket, Robinhood, and Crypto.com. The state's complaint centers on the language used by these platforms, which Wisconsin argues is more akin to gambling than investing. According to Attorney General Josh Kaul, "attempting to disguise unlawful activities as lawful ones does not make them so." The lawsuit raises a crucial question: are these contracts financial instruments subject to federal regulation, or are they simply bets governed by state law? This distinction will determine whether the industry operates under a unified federal framework or is subject to a patchwork of state regulations. The case is likely to ultimately be decided by the Supreme Court. Wisconsin's complaints target three main areas, naming Crypto.com, Polymarket, and Kalshi, along with its distribution partners Robinhood and Coinbase. The state argues that the so-called "event contracts" offered by these platforms are, in reality, 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. The state also points to the platforms' own marketing materials, which appear to acknowledge that they are, in fact, facilitating sports betting. For instance, Kalshi's Instagram ads claim that the platform is "The First Nationwide Legal Sports Betting Platform," while Polymarket's ads describe it as "a platform where people can bet on the outcome of future events." The state contends that the structure of these prediction markets falls squarely within its definition of a bet, regardless of how the products are labeled or who takes the other side of the trade. The complaints also highlight that the 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 the argument that federal law preempts state regulation. Kalshi, in particular, has argued that its contracts are swaps listed on a regulated exchange and therefore fall under the exclusive jurisdiction of the Commodity Futures Trading Commission (CFTC). This position received a boost when the Third Circuit sided with the company earlier this month. Nevertheless, state courts across the US have consistently taken a different stance, with Nevada and New York both characterizing the contracts as indistinguishable from gambling. Wisconsin's 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 exempt it from being treated as a bet.
