Polymarket is taking Massachusetts’ fight against another prediction market to court. Neal Kumar, the trading exchange’s CLO, stated on X that Polymarket filed a lawsuit against Massachusetts Attorney General Andrea Joy Campbell on Monday.
Polymarket’s legal strike comes after a state judge on Friday denied Kalshi’s request to delay its sports markets ban while it pursues an appeal to an injunction.
This decision came despite Kalshi’s argument that prediction markets are federally regulated by the Commodity Futures Trading Commission, not at the state level. Polymarket is stating the same case in its lawsuit.
“Congress gave the CFTC, not states, exclusive authority over event contracts,” Kumar posted.
