Federal Regulators Assert Control Over Prediction Markets Amid Jurisdictional Battles and Insider Trading Concerns

Prediction markets like Polymarket and Kalshi have scaled rapidly, with trading volumes reaching tens of billions monthly and projections toward trillions annually by 2030. These platforms aggregate crowd-sourced probabilities on events from elections to sports outcomes, often outperforming traditional forecasts. However, their rise has triggered regulatory responses that reveal tensions between federal oversight and decentralized information flows.

The U.S. Commodity Futures Trading Commission (CFTC), under Chairman Michael Selig since late 2025, has pivoted from earlier restrictive proposals. It withdrew a 2024 rule that would have banned political and sports-related event contracts, instead advancing new rulemaking for clearer standards.[1][2] Recent June 2026 proposals outline a framework allowing most sports contracts while restricting those prone to manipulation, such as player injuries or officiating calls, and signaling scrutiny over contracts involving war or assassination.[3][4]

This federal push coincides with clashes against state regulators. The CFTC has sued states including Minnesota and New York, arguing that state bans or gambling classifications intrude on federal authority over derivatives.[5][6] Multiple states have issued cease-and-desist orders or filed suits viewing these markets as unlicensed gambling, highlighting a federal-state power struggle over emerging financial instruments.

Enforcement actions underscore integrity concerns: The CFTC issued advisories on insider trading after cases involving political candidates trading on their own races and misuse of nonpublic information.[7][8] Congressional proposals seek to bar officials from trading certain contracts, framing the issue as anti-corruption rather than suppression of signals.[2]

Beyond regulation, these developments expose a novel dynamic: accurate, capital-backed forecasts challenge institutional monopolies on foresight, prompting efforts to channel markets through federal gates while curbing excesses. Academic analyses note expressive elements in prediction markets that could implicate free speech protections, distinguishing them from pure gambling.[9] The CFTC's approach balances innovation with safeguards, yet the pattern of jurisdictional assertions and targeted restrictions illustrates how information markets test boundaries of state power.
