**US Court Upholds State Regulation of Prediction Markets, Impacting Kalshi's Operations**
On September 25, 2026, the 6th US Circuit Court of Appeals in Cincinnati delivered a significant ruling regarding the regulation of prediction markets, siding against the company Kalshi in its attempt to exempt its event contracts from state gambling laws. This decision underscores the ongoing debate about the regulation of prediction markets, which have gained popularity in the United States.
Kalshi, a platform that allows users to bet on the outcomes of various events—ranging from sports and political elections to international negotiations—sought to clarify its legal standing in relation to state gambling regulations. The court's unanimous ruling, articulated by Judge Julia Smith Gibbons and supported by a three-judge panel, affirms that states like Ohio and Tennessee possess the authority to regulate these event contracts under their gambling laws.
This ruling adds to a growing body of legal interpretations surrounding prediction markets. Notably, it highlights a divergence in opinions among federal appeals courts regarding the extent of state versus federal regulatory powers over such markets. Recently, the 9th Circuit Court in San Francisco ruled that Kalshi's event contracts fall under Nevada’s gambling laws, while the 3rd Circuit in Philadelphia determined that they are not subject to New Jersey’s regulations. The conflicting decisions among these courts may pave the way for a potential review by the US Supreme Court, as the legal landscape surrounding prediction markets continues to evolve.
The rise of prediction markets has prompted ethical and regulatory scrutiny, particularly concerning their accessibility to younger audiences. Experts have voiced concerns about the implications of these platforms, especially as they become more integrated into mainstream culture. The ability for individuals to place bets on a wide array of topics raises questions about responsible gambling practices and the potential for addiction.
In a related development, the state of New York has recently taken action against another prediction market, Polymarket. The state filed a lawsuit claiming that Polymarket is operating as an unlicensed gambling entity. New York Governor Kathy Hochul emphasized the risks posed by such operations, particularly to vulnerable populations, including minors. Polymarket has indicated its intention to contest the lawsuit, asserting its commitment to its user base.
As prediction markets continue to proliferate, the regulatory landscape will likely remain contentious. The recent court rulings and state actions reflect a growing recognition of the need for oversight in this rapidly expanding sector. Stakeholders, including consumers, regulators, and companies like Kalshi and Polymarket, will need to navigate these complexities as they seek to balance innovation with responsible governance.
