An anonymous reader quotes a report from TechCrunch: Senators Adam Schiff (D-CA) and John Curtis (R-UT) introduced (PDF) a bill on Monday that could prevent prediction market platforms Kalshi and Polymarket from allowing users to wager money on sports events or play casino-style games. This bipartisan bill would not apply to FanDuel and DraftKings, which are subject to state-by-state gambling laws, rather than federal ones. "Sports prediction contracts are sports bets -- just with a different name. And yet, these contracts are currently offered in all fifty states in clear violation of state and federal law," Schiff said in a statement. Prediction markets like Kalshi and Polymarket are regulated under the Commodity Futures Trading Commission (CFTC), which is why Schiff and Curtis are able to address them under federal jurisdiction, rather than leaving them to state-regulated sportsbooks. But these senators argue that there isn't much of a difference in practice between betting on sports via federally or state-regulated apps. Kalshi's Super Bowl trading volume, for instance, reached over $1 billion this year -- a 2700% increase year-over-year. "Too many young people in Utah are getting exposed to addictive sports betting and casino-style gaming contracts that belong under state control, not under federal regulators," Curtis said in a statement. The report notes that Kalshi is temporarily banned in Nevada and is facing criminal charges in Arizona. "Kalshi may brand itself as a 'prediction market,' but what it's actually doing is running an illegal gambling operation and taking bets on Arizona elections, both of which violate Arizona law," Arizona Attorney General Kris Mayes said in a statement last week.Read more of this story at Slashdot.
