Overview
Kalshi’s first suit in the Fifth Circuit, and a pre-emptive one: Louisiana has not sued or fined it. Kalshi sued Attorney General Liz Murrill, Governor Jeff Landry, the Gaming Control Board and its members, and the State Police gaming division on October 23, 2026, saying it believes the State “will imminently bring an enforcement action.” The complaint relies on the Board’s December 5, 2025 Advisory Notice, which said the Board “considers purported sporting event contracts and certain other event contracts as illegal gambling,” and on public statements by Murrill and Board chair Christopher Hebert, who said the State is “actively seeking ways to stop this.” It also points to enforcement tools, La. R.S. 27:19.1 and 27:19.2, which Kalshi says let the Attorney General seek orders removing websites and freezing accounts.
It pleads one count, preemption under the Supremacy Clause, and asks for a declaration and a temporary restraining order and preliminary and permanent injunctions against enforcement of Louisiana’s gambling and sports-wagering laws. Kalshi also notes that Louisiana’s computer-gambling statute exempts transactions on a commodities exchange. (Caption, defendants, court, docket and filing date read from the file-stamped complaint.)
