A group of prediction market operators, which includes Kalshi, Crypto.com, and Polymarket, has initiated legal action against the state of Kentucky regarding a newly implemented tax on prediction market transactions. They argue that this tax is both discriminatory and in violation of federal law.
The lawsuit, brought forth by the Coalition for Fair Markets in Kentucky's state court, contests a 14.25% excise tax on transaction fees imposed on prediction market operators, a measure that was passed by the Kentucky General Assembly in April.
Prediction markets enable users to buy, sell, and trade contracts based on the outcomes of real-world events, including elections, economic indicators, sports, and weather forecasts.
The plaintiffs assert that Kentucky's tax is the first of its kind, specifically targeting transactions on federally regulated derivatives exchanges, and unfairly contrasts with the state’s horse racing industry.
Currently, wagers made at Kentucky horse tracks are taxed at a rate of 9.75%, which is significantly lower than the 14.25% tax imposed on prediction market operators.
The lawsuit highlights that no other state has implemented a specific excise tax on derivatives transactions occurring on federally designated exchanges, particularly one that is as targeted and discriminatory as Kentucky's.
The coalition claims that the tax is unconstitutional, superseded by federal law, and deters prediction market companies from establishing operations in Kentucky.
Kentucky's Attorney General, Russell Coleman, has vowed to uphold the law against this legal challenge. He stated, “You can bet our Office will defend these statutes and the people of our Commonwealth from out-of-state companies that seek to cancel Kentucky's sports betting laws.” He expressed confidence in the legal team’s ability to prevail in court.
Kalshi warned that the tax could inadvertently drive users away from regulated platforms, stating, “Taxing federally regulated markets just pushes people toward illegal platforms with no oversight and no protections.”
Kalshi emphasized its commitment as a regulated American company, stating, “We’re joining the fight for Kentuckians' access to safe, legal markets.”
This lawsuit emerges at a time when prediction market operators are striving for greater recognition among regulators and policymakers, aiming to establish their platforms as credible venues for trading contracts related to future events.
The sector has faced increased scrutiny due to allegations that some users have gained from insider information. Notably, former U.S. Congressman George Santos is reportedly under investigation for trades linked to President Donald Trump's State of the Union address, while a U.S. Army soldier was charged in April for using classified information to profit approximately $400,000 on Polymarket concerning U.S. military operations in Venezuela.
This case represents the latest legal and regulatory challenge facing prediction markets as both state and federal authorities continue to deliberate on appropriate taxation and regulation for this rapidly expanding industry.
