Kalshi sues Louisiana officials in federal court to block enforcement against its sports event contracts

Kalshi filed a pre-emptive lawsuit against Louisiana on Friday in the US District Court for the Western District of Louisiana. The company argues that state officials showed a “clear intention to violate the Supremacy Clause” through efforts to shut down prediction markets. Defendants include Attorney General Liz Murrill, Gov. Jeff Landry, Louisiana Gaming Control Board (LGCB) Chair Christopher Hebert, LGCB Gaming Division Director Dawn Himel, and the Louisiana State Police Gaming Enforcement Division.
