The Commodity Futures Trading Commission sued Kentucky on Tuesday after the state targeted prediction market platforms Kalshi and Polymarket, making Kentucky the first Republican-led state to face federal legal action in the ongoing jurisdictional battle.
The Commodity Futures Trading Commission filed suit against Kentucky on Tuesday, escalating the agency's ongoing legal campaign to defend its exclusive jurisdiction over prediction markets — and marking the first time it has targeted a state with a Republican attorney general.
The action follows Kentucky Attorney General Russell Coleman's lawsuit last week against prediction market platforms Kalshi and Polymarket, in which he accused the companies of operating illegal gambling platforms within the state.
Kentucky is now the ninth state the CFTC has sued in its effort to block state-level regulation of event contracts. All eight previous targets had Democratic attorneys general, even as states from both parties have moved against the platforms.
"Kentucky is the latest state attempting to shut down federally-regulated event contracts," CFTC Chair Michael Selig said in a press release announcing the lawsuit. "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."
Coleman's office did not immediately respond to a request for comment on the CFTC's countersuit.
In his own press release last week, Coleman had been direct in characterizing the platforms. "Kalshi and Polymarket are operating illegal sportsbooks in Kentucky and breaking our laws," he said. "These multi-billion dollar corporations and their legal fictions don't pass the sniff test."
The dispute reflects a broader, unresolved tension between federal and state regulators over who controls prediction markets. States contend they have the authority to regulate sports-related event contracts because those products resemble sports betting — an industry long governed at the state level. The CFTC counters that event contracts qualify as swaps, placing them squarely under the commission's mandate.
In total, 20 states are currently involved in active litigation against prediction market platforms. At least one state has gone further, moving to ban the platforms outright.
The CFTC's decision to sue Kentucky is notable because it breaks the partisan pattern that had characterized the commission's enforcement record to date. By taking action against a Republican-led state, the agency — itself operating under the Trump administration — signals that its jurisdictional claims are not contingent on the political alignment of the opposing attorney general.
Kentucky joined 19 other states in that active litigation pool, underscoring how broadly state governments have pushed back against what they view as federally protected platforms operating in legal gray zones within their borders.
Coleman's office had framed its initial lawsuit as a straightforward law enforcement matter. The CFTC's response reframes it as a constitutional question about the limits of state authority over federally regulated financial instruments.
How courts ultimately resolve that question will shape not only the future of Kalshi and Polymarket, but the regulatory architecture governing the broader prediction market industry at a moment when these platforms have grown substantially in visibility and user activity.
