CFTC sues Louisiana and Arkansas to block state bans on event contracts
The Commodity Futures Trading Commission sued Louisiana on November 13 and Arkansas on November 12 to block state court orders and gaming laws barring CFTC-regulated exchanges from offering event contracts. The Louisiana suit challenges a state court order that shut down more than 30 firms without notice or hearing. Both cases assert federal preemption over state gambling enforcement. The dual filings escalate a confrontation between federal and state authority over prediction-market oversight.
The Louisiana and Arkansas suits test whether the CFTC's litigation offensive can outpace state courts that have already stripped Kalshi's federal shield in Ohio and Tennessee. For Kalshi, Polymarket US, Robinhood, and other registered platforms, each new federal filing buys only weeks against state timelines that move faster. The agency's swap-rule proposal remains in White House review and cannot outrun criminal summons in Utah on December 4.
A federal defeat in either state would give every attorney general a roadmap to sue federally registered exchanges without federal interference. Platforms now fund parallel federal offensive and state defensive litigation simultaneously, with founder felony exposure adding personal stakes no corporate shield can absorb. The first platform that fails to lift an immediate halt will see competitors pull products rather than risk contempt or criminal charges.
This Louisiana filing joins an Arkansas suit filed by the DOJ and CFTC this week as the agency's twelfth federal preemption action against states that have already stripped Kalshi's federal shield in Ohio and Tennessee, with Robinhood and Polymarket also pursuing their own preemptive state-court defenses.
