TechFlow reported on June 14 that Coalition for Fair Markets, a group that includes Kalshi, Polymarket and other institutions, has filed a lawsuit in a Kentucky court challenging the state’s recently implemented 14.25% consumer tax policy for prediction markets. The case centers on whether the state’s tax treatment places an unfair burden on regulated prediction market platforms operating in the jurisdiction.
Coalition Challenges Higher Rate Than Horse Racing Wagers
According to the lawsuit, Kentucky’s 14.25% tax rate on prediction markets is significantly higher than the 9.75% rate applied to horse racing betting businesses in the state. The plaintiffs argue that this difference amounts to discriminatory treatment of the prediction market industry and changes the tax conditions under which these platforms conduct business.
The plaintiffs also contend that prediction markets fall within the category of federally regulated financial markets. On that basis, they argue that state-level tax measures may be limited by the principle of federal preemption. The lawsuit therefore touches on the legal classification of prediction markets, the scope of state taxation authority, and the relationship between federal regulatory frameworks and local tax policy.
Tax and Regulatory Disputes Continue to Escalate
Coalition for Fair Markets said an excessive tax burden would weaken the competitiveness of regulated prediction market platforms, restrain industry innovation and market development, and drive some users toward offshore platforms without regulation or illegal markets. In recent years, the prediction market industry in the United States has developed rapidly, with contract trading volumes continuing to grow around elections, economic data, sports events and policy-related events.
At the same time, disputes between state regulators and prediction market platforms have intensified around regulatory authority, whether such products should be classified as gambling, and how tax policy should apply. Kentucky has stated that it will actively defend the relevant law and protect the state government’s right to tax commercial activities within its jurisdiction. The outcome of this lawsuit is also expected to have an important influence on how other U.S. states regulate and tax the prediction market industry in the future.
