Robinhood asked a US judge to block Massachusetts from applying its gaming laws to its sports prediction operations one day after a state court approved an action targeting Kalshi’s sports betting.
The preliminary injunction filed Tuesday, if granted, would make Massachusetts a microcosm of the legal split playing out in litigation across the country, as judges have come down on both sides of whether states can apply their laws to the federally regulated markets.
Robinhood, which offers sports contracts through Kalshi’s and ForecastEx’s markets, told the federal judge that Massachusetts’ gaming laws are preempted by the Commodity Exchange Act’s framework for futures and swaps trading, citing rulings from cases in New Jersey, Nevada, and California.
