An anonymous reader quotes a report from Reuters: A federal appeals court ruled on Monday that New Jersey gaming regulators cannot prevent Kalshi from allowing people in the state to use its prediction market to place financial bets on the outcome of sporting events.A three-judge panel of the Philadelphia-based 3rd U.S. Circuit Court of Appeals ruled 2-1 (PDF) in finding that the U.S. Commodity Futures Trading Commission has exclusive jurisdiction over the sports-related event contracts that Kalshi allows people to trade on its platform. The ruling marked the first time a federal appeals court has ruled on what has become the central issue in an escalating battle over the ability of state gaming regulators to police the activity of prediction market operators. Kalshi and companies like it allow users to place trades and profit from predictions on events such as sports and elections. States argue that firms like Kalshi are operating without required state licenses, in violation of gaming laws, including bans on wagers by those under 21. Those states include New Jersey, which last year sent Kalshi a cease-and-desist letter stating that its listing of sports-related event contracts on its platform violated state gambling laws that prohibit betting on collegiate sports. Kalshi sued the state, arguing its event contracts qualify as "swaps," a type of derivative contract, that under the Commodity Exchange Act can only be regulated by the CFTC, which had granted the company a license to operate a designated contract market (DCM). A lower-court judge had sided with New York-based Kalshi and issued a preliminary injunction, prompting New Jersey to appeal. But a majority of the judges on the 3rd Circuit panel concluded the Commodity Exchange Act likely preempted state law. "Kalshi's sports-related event contracts are swaps traded on a CFTC-licensed DCM, so the CFTC has exclusive jurisdiction," U.S. Circuit Judge David Porter wrote. The ruling was in line with the position advanced in other litigation by the CFTC under President Donald Trump's administration. The regulator last week sued Arizona, Connecticut and Illinois to prevent them from pursuing what it called unlawful efforts to regulate prediction markets.Read more of this story at Slashdot.
