The Commodity Futures Trading Commission (CFTC) has filed a lawsuit against Kentucky, aiming to block state laws that the federal regulator says interfere with its exclusive authority over prediction markets. The case, filed on 23 June 2026, challenges Kentucky’s efforts to regulate federally registered contract markets through taxes, fees, and enforcement actions.
At issue are Kentucky’s civil cases against CFTC-registered designated contract markets and a new state fee targeting event contract trading. Federal regulators argue these measures conflict with Congress’s decision to assign exclusive oversight of such markets to the CFTC.
Federal Oversight Versus State Measures
CFTC Chairman Michael S. Selig said Kentucky is part of a wider trend of state actions against prediction markets. He stated: “Kentucky is the latest state attempting to shut down federally-regulated event contracts,” noting their role in providing information and risk management tools.
He added: “As I’ve consistently pledged, the CFTC is firmly committed to maintaining its exclusive jurisdiction over prediction markets, and today’s lawsuit against Kentucky is yet another example of the Commission protecting its federal interests.”
The agency has previously taken similar legal action against multiple states and filed supporting briefs in related appellate and state-level cases.
Kentucky’s Restrictions and Industry Response
Kentucky has introduced a proposed 14.25% tax on prediction market transactions and plans to bar licensed gaming operators from working with event contract providers. These measures have prompted legal challenges from industry participants including Crypto.com, Kalshi, and Polymarket, who argue the rules are discriminatory and unworkable.
The state has also pursued enforcement actions against several companies operating in gambling and gaming-related sectors. Officials argue the laws protect residents and uphold state gaming regulations.
Kentucky Attorney General Russell Coleman has pledged to defend the statutes and has initiated additional lawsuits seeking injunctions and penalties against multiple operators.
Expanding National Dispute
The dispute forms part of a broader national conflict between federal and state authorities over prediction markets. The CFTC has now initiated cases in nine states, including Arizona, Connecticut, Illinois, Minnesota, New Mexico, New York, Rhode Island, and Wisconsin. Kentucky becomes the first state governed by a Republican administration to face such a lawsuit from the agency.
In each case, the CFTC has argued that states are exceeding their authority by attempting to ban, tax, or regulate federally registered event contract platforms. The commission maintains that federal law pre-empts state gaming regulations in this area, leaving jurisdiction exclusively at the national level.
States involved in these disputes have taken the position that prediction markets resemble traditional gambling products and should therefore fall under state gaming laws, particularly when linked to sports-related contracts.
Alongside the legal disputes, the CFTC has recently published proposals outlining a more permissive approach to prediction markets, including sports-related offerings. That position has drawn criticism from gaming groups, tribal operators, and former regulators, who argue the framework lacks sufficient safeguards.
As litigation continues to expand across multiple jurisdictions, the outcome of the Kentucky case may further define the balance of authority between federal regulators and states over prediction market activity.
