Prediction markets have created one of the more fascinating regulatory questions of the digital economy: When Americans buy contracts predicting whether an election will be won, interest rates will fall, a movie will win an Oscar, or a football team will prevail, are they investing in information—or simply gambling with more sophisticated terminology?
The answer matters because prediction markets are rapidly moving into territory traditionally occupied by sportsbooks while simultaneously claiming the legal protections of federally regulated financial markets. That collision has produced a growing fight between federal regulators and states over who gets to make the rules.
Prediction markets generally allow participants to purchase contracts tied to future events. A contract might ask whether inflation will exceed a certain level, whether Congress will pass legislation, or whether a particular team will win a game. Prices fluctuate as participants buy and sell, effectively producing a continuously changing estimate of the probability that an event will occur.
That mechanism gives prediction markets genuine informational value. Markets aggregate thousands of individual judgments, with participants risking money when they believe the collective assessment is wrong. The Commodity Futures Trading Commission itself describes prediction markets as tools that can forecast events, hedge risks and aggregate information. Federally regulated event contracts are generally structured as derivatives, often swaps, and exchanges are subject to requirements intended to prevent manipulation and other abuses.
Yet the gambling comparison cannot simply be dismissed.
Consider a contract asking whether an NFL team will win Sunday. A customer puts money at risk. The customer’s profit depends upon an uncertain sporting event. If the prediction is correct, the customer makes money; if it is wrong, the customer loses money. To the ordinary American, the distinction between that transaction and placing a wager at a sportsbook can become remarkably difficult to explain.
That has become more than a philosophical argument. In August 2026, the Ninth Circuit ruled that Nevada could subject Kalshi’s sports-related prediction contracts to state gaming oversight, rejecting the argument that federal commodities law necessarily displaced Nevada’s authority. Other litigation has produced different conclusions, leaving a developing conflict over the boundary between federal derivatives regulation and traditional state gambling authority.
Meanwhile, the CFTC has aggressively defended its jurisdiction. The agency argues that Congress gave it exclusive authority over federally regulated derivatives markets, including qualifying event contracts, and during 2026 it challenged attempts by several states to apply their gambling laws to federally regulated prediction markets.
There is a legitimate federalism question here. States have traditionally exercised broad police powers over gambling, and they have developed regulatory systems governing sportsbooks, casinos and other wagering operations. Washington should not be permitted to erase legitimate state authority merely by attaching the word “derivative” to something that functions indistinguishably from a wager.
But the opposite problem is equally serious. States should not be allowed to transform nationally traded financial instruments into a patchwork system in which an event contract is a regulated derivative in Wisconsin, prohibited gambling in Nevada and something entirely different in New York.
The better approach is to regulate according to what the product actually does rather than what either industry or government chooses to call it.
There is an obvious difference between a business purchasing contracts to hedge against an economic event and a consumer putting $50 on whether the Packers beat the Bears. There are also substantial differences between markets predicting inflation, elections, weather, congressional action and sporting events. Pretending every event contract belongs in precisely the same regulatory category creates more confusion than clarity.
Congress should establish that boundary rather than leaving regulators, state attorneys general and federal courts to construct it through years of litigation.
Financial event contracts with legitimate price-discovery, forecasting or hedging functions fit naturally within federal commodities regulation. The CFTC already oversees derivatives exchanges and possesses experience policing manipulation, market integrity and trading misconduct. The agency has also demonstrated that prediction markets create familiar financial-market problems: in February 2026, its enforcement division highlighted cases involving misuse of nonpublic information and fraud on prediction markets.
Pure sports wagering presents a harder case. When a contract’s principal economic purpose is simply allowing consumers to risk money on which team wins a game, state gaming regulators have a much stronger claim that the activity falls within their traditional jurisdiction.
The distinction will never be perfect. Financial innovation rarely fits comfortably inside regulatory categories written decades earlier. But uncertainty is not an argument for unlimited government power. It is an argument for clear law.
Prediction markets should neither receive a regulatory exemption because they call gambling “trading” nor automatically be treated as casinos because participants can lose money. Americans lose money trading stocks, commodities and options too. Risk alone does not make something gambling.
The question is the economic substance of the transaction.
Prediction markets occupy territory between Wall Street and Las Vegas, and regulators are now fighting over where the border lies. Congress should draw that border clearly: preserve federal authority over genuine national derivatives markets, preserve traditional state authority over genuine gambling, and prevent either side from expanding its jurisdiction simply by redefining the product.
Innovation deserves room to develop. So does federalism. The challenge is protecting both without pretending that every prediction is either an investment—or a bet.
