Key Takeaways
- Kentucky has become the ninth state to face legal action from the CFTC regarding prediction market regulation.
- Last week, Kentucky initiated legal proceedings against Kalshi, Polymarket, Coinbase, Robinhood, and Webull, alleging they operated illegal gambling operations.
- Federal regulators assert they hold sole jurisdiction over prediction market oversight, claiming Kentucky has exceeded its authority.
- A 14.25% excise tax on transaction fees imposed by Kentucky effectively prevents prediction platforms from functioning within state borders, according to the CFTC.
- Since assuming office in December, CFTC Chair Mike Selig has prioritized developing comprehensive federal regulations for the prediction market industry.
The Commodity Futures Trading Commission has initiated federal legal proceedings against Kentucky, attempting to prevent the state from implementing its regulations targeting prediction market operators.
On Tuesday, the complaint was submitted to the U.S. District Court for the Eastern District of Kentucky. Governor Andrew Beshear, Attorney General Russell Coleman, and the Kentucky Horse Racing and Gaming Corporation are listed as defendants in the case.
Prior to this action, Kentucky had launched its own legal challenge, naming prediction market operators Kalshi and Polymarket as defendants, alongside their partner platforms Coinbase, Robinhood, and Webull. State officials accused these entities of conducting operations without obtaining proper Kentucky gaming authorization.
The state further contended that these platforms failed to provide adequate resources for users to recognize or address gambling addiction issues, a requirement mandated by Kentucky statutes.
Federal Regulators Assert Sole Jurisdiction
The CFTC responded forcefully to Kentucky’s allegations. The agency maintained that Kalshi and Polymarket function as designated contract markets under federal regulatory oversight. According to the commission, their event-based contracts qualify as “swaps” within the framework of federal commodities legislation.
Federal officials further contended that Coinbase, Robinhood, and Webull hold valid registrations as futures commission merchants, granting them legal authority to collaborate with these prediction market operators.
“Kentucky is the latest state attempting to shut down federally-regulated event contracts,” CFTC Chair Mike Selig said in a statement.
The commission specifically highlighted Kentucky’s legislation imposing a 14.25% excise levy on prediction market transaction fees. According to the CFTC, this tax “essentially makes it impossible for prediction markets to operate in Kentucky.”
Since 2023, sports wagering oversight has fallen under the Kentucky Horse Racing and Gaming Corporation’s purview, forming the foundation of the state’s legal position.
A Growing List of State Battles
With this latest action, Kentucky joins eight other states facing federal lawsuits from the CFTC. The commission has previously filed complaints against Wisconsin, Illinois, Arizona, Connecticut, New York, New Mexico, Minnesota, and Rhode Island.
Across all these legal challenges, the CFTC maintains a consistent position: federal legislation holds primacy over prediction market governance, and state regulations cannot supersede federal authority.
Recently, the CFTC initiated comparable legal action against New Mexico following that state’s attempt to enforce its gaming statutes against Kalshi.
In May, President Donald Trump emphasized the “critically important” nature of preserving the CFTC’s regulatory control over prediction markets.
Donald Trump Jr., the president’s son, has made financial commitments to Polymarket and serves in advisory capacities for both Polymarket and Kalshi.
Since assuming his position in December, CFTC Chair Selig has worked to establish a comprehensive regulatory structure for the prediction market sector. Under his direction, the commission has introduced proposed regulations that would generally permit sports-related wagering on prediction platforms, while restricting contracts connected to terrorism or political assassinations.
During the 2024 election season, platforms such as Kalshi and Polymarket experienced substantial growth and currently enable users to place wagers on diverse events, including political contests and athletic competitions.
