This week, Kentucky’s top law enforcement official, Attorney General Russell Coleman, initiated state court proceedings targeting the prediction market operators Kalshi and Polymarket. The legal complaints allege both platforms are conducting unauthorized sports wagering operations within Kentucky’s borders.
The legal documents additionally identify Coinbase, Robinhood, and Webull as parties to the action due to their partnership with Kalshi. According to state authorities, these financial services companies have not fulfilled Kentucky’s legal requirement to make gambling addiction resources available to users.
“Kalshi and Polymarket are operating illegal sportsbooks in Kentucky and breaking our laws,” Coleman declared in an official statement.
Combined, Kalshi and Polymarket generated approximately $25 billion in trading activity during May, per Token Terminal data. Losing access to significant U.S. markets could substantially impact their expansion plans.
Both Kalshi and Polymarket maintain they operate as federally supervised exchanges. Their position is that their event-based contracts qualify as swaps under federal commodity regulations, distinguishing them from state-regulated sports gambling.
“Kalshi is a federally regulated exchange — the CFTC is our regulator, not the states,” stated a representative from Kalshi.
Red State Challenges Trump Administration’s Position
Kentucky’s legal strategy creates a noteworthy political contradiction. The state delivered a commanding 64% vote for President Donald Trump in the 2024 election. Yet this enforcement action runs counter to Trump’s publicly stated views on prediction market oversight.
On Truth Social, Trump has advocated for the CFTC to maintain sole regulatory authority over prediction markets. He has used harsh language against state-level enforcement efforts, referring to opponents as “SCUM” while expressing support for CFTC Chairman Mike Selig.
The CFTC has launched legal challenges against eight states that have pursued action against prediction market companies, contending these states are exceeding their authority. Kentucky may face similar federal pushback.
Despite this potential conflict, Coleman—a Republican who previously served as a Trump-appointed federal prosecutor—continues to pursue the case.
Polymarket responded that Kentucky’s enforcement action “runs counter to the CFTC’s established framework.” The platform indicated it would defend itself through appropriate legal channels.
Conflicting Judicial Rulings as Litigation Expands
Judicial decisions have produced mixed outcomes across different jurisdictions. Coinciding with Kentucky’s filing, a federal judge in Michigan delivered an unfavorable verdict for Polymarket, determining that its sports-related contracts fall outside federal commodities law protection.
Conversely, the Third Circuit Court of Appeals determined in April that New Jersey lacked authority to prohibit Kalshi from providing sports event contracts within its jurisdiction.
A minimum of 17 additional states have initiated legal proceedings against prediction market companies. Legal analysts anticipate the dispute will ultimately require resolution by the U.S. Supreme Court.
Both Kalshi and Polymarket had previously filed their own lawsuit against Kentucky challenging the state’s 14.25% levy on prediction market transaction fees, characterizing it as unfairly discriminatory.
Donald Trump Jr., the president’s son, serves on Polymarket’s advisory board and maintains an advisory relationship with Kalshi.
