Experts Warn Prediction Market Disputes May Reach Supreme Court

The nation’s highest court may decide the future of prediction markets in the United States as disputes between states, platforms, and federal regulators leave the sector shrouded in uncertainty. Industry experts speaking at the NEXT Focus: Emerging Verticals conference in New York this week said the fast-growing sector is on a collision course with the courts as various stakeholders struggle to determine who should supervise the industry.

A Supreme Court Intervention May Be Inevitable

While experts generally agree that the dispute surrounding prediction markets will eventually reach the Supreme Court, most agree that such a development would not occur until 2027 at the earliest. A definitive ruling could finally settle the long-running debate on whether trading on the outcome of real-world events should be treated as financial exchanges or as a form of gambling.

A recent Next.io report shared insights by Andrew Kim, a partner at Goodwin Procter LLP, who has previously argued before the Supreme Court. He argued that the legal process leading to such a decision could unfold quickly if courts across the country begin issuing conflicting rulings. Ongoing disputes across federal appeals courts and state judicial systems could set the stage for such a development.

We could conceivably get a decision as soon as the next year and a half, or it could be 2029. It’s hard for any of us to predict what exactly the court is going to do.

Should court rulings diverge, Kim believes the Supreme Court may choose to hear a case that will determine whether federal derivatives law takes precedence over state gambling regulations. A decision could theoretically arrive within the next year, although a longer timeline is also plausible. Shifting political priorities could also influence this process, as the current administration is highly favorable of prediction markets.

Disputes Show No Sign of Subsiding

Much of the ongoing controversy stems from the breadth of events that prediction markets allow users to trade on. Platforms such as Kalshi offer contracts tied to elections, economic indicators, policy decisions, and even sports. Supporters argue that these markets are useful forecasting tools and often generate more accurate signals than traditional polling.

Critics see something different. State regulators and tribal gaming authorities, together with many traditional sportsbook operators, believe that many of these contracts resemble wagers rather than financial instruments. In their view, sports contracts are the most egregious, as they circumvent established gambling laws and do not provide adequate consumer protections.

Several states have already begun pushing back. Some jurisdictions have filed lawsuits against prediction platforms, while others are considering legislation to subject the activity to state gaming oversight. As these disputes multiply, legal observers expect conflicting rulings to emerge from different courts, making a Supreme Court intervention increasingly likely. Until then, the industry will likely remain shrouded in uncertainty.
