The Ninth Circuit Court of Appeals issued a unanimous 3‑0 decision Friday that states have the power to regulate prediction‑market platforms as gambling. The ruling marks the most significant victory for state regulators in the ongoing legal battle over whether these sites operate as financial exchanges or as games of chance.
Trump‑appointed judges lead the decision
The panel was composed of three judges appointed by President Trump, underscoring the administration’s longstanding support for state‑level oversight of emerging financial technologies. The case originated in Nevada, where state regulators sought to ban the Kalshi prediction market for violating state gaming statutes.
Federal backing versus state authority
Since the Trump administration began treating prediction markets such as Kalshi and Polymarket as federally regulated exchanges, states have argued that the platforms are fundamentally gambling activities and should fall under state gaming laws and tax regimes. The Ninth Circuit’s opinion affirms that argument, stating that states may apply their own gambling regulations to these platforms.
Implications for the industry and future litigation
While the ruling is a clear win for state regulators, the legal fight is far from over. Lawsuits continue in several states, and many legal experts anticipate that the Supreme Court will ultimately decide the constitutional balance between federal oversight and state police powers in this arena.
Earlier this year, the Third Circuit Court of Appeals sided with prediction‑market operators, blocking New Jersey’s attempt to enforce its state gaming laws. The contrasting decisions highlight the fragmented legal landscape and suggest that a definitive resolution may require the nation’s highest court.
What this means for consumers and businesses
For users of prediction‑market platforms, the decision could lead to varied state‑by‑state rules, potentially limiting access in states that choose to enforce gambling restrictions. Companies operating these markets will need to navigate a patchwork of state regulations, which may affect their business models and the range of events they can offer.
Industry observers note that the ruling reinforces the principle of federalism—allowing states to exercise their constitutional authority to protect residents from activities deemed harmful or exploitative. Supporters argue that this approach safeguards families and upholds community standards, while critics warn it could stifle innovation in a growing sector of the digital economy.
Looking ahead
The Trump administration has signaled its intent to continue defending the right of states to regulate prediction markets, aligning with broader efforts to protect consumers and uphold traditional values. As the legal battle proceeds, stakeholders on both sides are preparing for a possible Supreme Court review that could set a lasting precedent for how emerging financial technologies are governed in the United States.
