State Gambling Laws and Prediction Markets

Utah lawmakers have passed, and Gov. Spencer Cox says he will sign, a bill expanding the state’s long‑standing gambling ban to cover prediction markets such as Kalshi and Polymarket, setting up a direct confrontation with federal regulators and crypto‑style wagering platforms operating nationwide. The law is designed to block proposition-style betting, especially on sports events, by treating these markets as gambling rather than financial risk‑management tools, even as the Commodity Futures Trading Commission backs Kalshi’s effort to operate as a federally regulated exchange. Kalshi has already sued Utah, arguing its contracts are financial derivatives akin to binary options and futures long traded on exchanges like the Chicago Mercantile Exchange, while Utah officials frame the issue as a moral fight driven by the state’s Latter‑day Saint–inflected, anti‑gambling tradition and concerns about “a casino in the pocket of every single American.” The article notes that Kalshi and Polymarket are each estimated to be worth around $20 billion and that President Donald Trump’s eldest son advises both companies and invests in Polymarket, as Trump’s Truth Social prepares its own cryptocurrency-based prediction platform, raising questions about how much legal and political protection this industry will get in Washington. Legal scholars say the emerging Utah case could become a template for whether states can keep these markets out under gambling law, or whether prediction markets will be treated as finance pre‑empted by federal authority, with major implications for retail speculators and the line between trading and betting nationwide.
