Key Points
- Kentucky has become the ninth state facing federal litigation from the CFTC regarding prediction market regulation.
- Last week, Kentucky filed suit against major platforms including Kalshi, Polymarket, Coinbase, Robinhood, and Webull, alleging they operated unlicensed gambling operations.
- Federal regulators argue they hold sole jurisdiction over prediction markets under commodities law, claiming Kentucky has exceeded its authority.
- A newly enacted 14.25% excise tax on transaction fees could effectively eliminate prediction market operations within Kentucky’s borders, according to the CFTC.
- Since assuming leadership in December, CFTC Chair Mike Selig has been working to create comprehensive federal regulations for the prediction market industry.
Federal commodities regulators have initiated legal action against Kentucky, challenging the state’s authority to enforce gambling regulations against prediction market operators.
The complaint was submitted to the U.S. District Court for the Eastern District of Kentucky this Tuesday. Named as defendants are Governor Andrew Beshear, Attorney General Russell Coleman, and the Kentucky Horse Racing and Gaming Corporation.
This federal action comes on the heels of Kentucky’s own legal offensive launched the previous week. The state’s lawsuit targeted prediction platforms Kalshi and Polymarket, alongside their partner companies Coinbase, Robinhood, and Webull, accusing them of conducting business without proper state gaming authorization.
Kentucky’s complaint further contended that these platforms failed to provide adequate resources for users to recognize or seek assistance for gambling addiction issues, which state regulations mandate.
Federal Regulator Asserts Sole Jurisdiction
The CFTC mounted a vigorous defense. The agency maintained that Kalshi and Polymarket operate as federally designated contract markets under national oversight. Their event-based contracts qualify as “swaps” according to federal commodities regulations, the commission stated.
Additionally, the regulator emphasized that Coinbase, Robinhood, and Webull hold valid registrations as futures commission merchants, granting them legal authority to collaborate with prediction market platforms.
“Kentucky is the latest state attempting to shut down federally-regulated event contracts,” CFTC Chair Mike Selig said in a statement.
The CFTC took particular issue with Kentucky’s newly implemented 14.25% excise tax levied on prediction market transaction fees. According to the agency, this tax rate “essentially makes it impossible for prediction markets to operate in Kentucky.”
Since 2023, the Kentucky Horse Racing and Gaming Corporation has held regulatory authority over sports wagering within the state, forming the foundation of Kentucky’s legal position.
Expanding Federal-State Conflict
With this action, Kentucky joins eight other states currently facing CFTC litigation. The federal agency has previously brought suits against Wisconsin, Illinois, Arizona, Connecticut, New York, New Mexico, Minnesota, and Rhode Island.
Across all these legal battles, the CFTC maintains a consistent position: federal legislation takes precedence in governing prediction markets, and individual state laws cannot supersede that authority.
Mere weeks ago, the CFTC initiated comparable legal proceedings against New Mexico after state officials attempted to apply local gaming statutes to Kalshi’s operations.
In May, President Donald Trump publicly stated it was “critically important” for the CFTC to preserve its regulatory control over prediction market platforms.
Donald Trump Jr., the president’s son, has made financial investments in Polymarket and serves in advisory capacities for both Polymarket and Kalshi.
Since assuming his position in December, CFTC Chair Selig has been actively developing a comprehensive regulatory structure for the prediction market sector. Under his direction, the CFTC has introduced proposed regulations that would generally permit sports-related wagering on prediction platforms, while restricting markets connected to terrorism or political assassinations.
Prediction market platforms such as Kalshi and Polymarket experienced explosive growth throughout the 2024 election season and currently enable users to place wagers on diverse outcomes spanning political contests to professional sports competitions.
