Key Points:
- The CFTC has introduced a 267-page regulatory proposal to govern the surging prediction markets sector.
- Under the draft plan, the federal agency bans bets on sensitive areas like war, assassinations, and terrorism.
- Most mainstream sports event contracts will remain legal but undergo strict scrutiny to prevent match manipulation.
- President Donald Trump has backed the federal agency’s sole oversight, overriding opposition from state officials.
The Commodity Futures Trading Commission took a major step toward establishing federal oversight over the fast-evolving prediction market industry. Led by Chairman Michael Selig, the regulatory body released a comprehensive 267-page proposal designed to define the rules of the road for retail event betting. This framework will directly impact digital platforms like Kalshi and Polymarket, which allow users to trade contracts on the outcomes of real-world events. By formalizing these guidelines, federal regulators want to protect investors and maintain market integrity without stifling the financial technology sector’s rapid growth.
The proposed rules arrive during a massive boom in prediction market activity, driven by retail traders seeking alternative financial instruments. The sector’s trading volume has surged past previous industry records. Registered event contract markets processed over $25 billion in total transactions in April alone, illustrating the massive financial scale of these platforms. Total global trading volume reached $51 billion in 2025, and market analysts estimate it could swell to $240 billion by the end of the decade as mainstream adoption increases.
A primary concern for market participants was the potential for a federal crackdown on sports-related event contracts. However, the commission’s draft rules would preserve most sports contracts, which currently drive a major share of trading volume. While the agency will continue to permit broad wagers on match outcomes, it will create a system to weed out highly manipulative bets. Under this new structure, regulators can block micro-bets that are susceptible to localized tampering, such as predicting a player’s sudden injury status or specific referee officiating decisions.
To determine the legality of future contracts, the agency plans to apply a flexible, case-by-case public-interest test rather than outright categorical bans. Nevertheless, the commission has drawn a clear line regarding sensitive and potentially harmful topics. The draft guidelines explicitly prohibit any event contracts associated with terrorism, physical assassinations, or armed conflict. For instance, the agency will block any contract that allows traders to speculate on the success of a terrorist attack. Conversely, benign public administrative decisions, such as changes to federal airport security protocols, will remain fully tradeable.
This push for centralized federal oversight has triggered a fierce legal and political battle with state governments. Attorneys general from more than 30 states have actively opposed the growth of prediction markets, arguing that they function as unregulated gambling operations. State officials point to transaction data showing that Kalshi users traded over $1 billion across 3.4 million individual sports contracts during a single six-month window. The states argue that local gaming laws should govern these activities to protect vulnerable citizens from developing gambling habits, prompting numerous state-level lawsuits against the platforms.
Despite this intense state-level opposition, President Donald Trump has thrown his full support behind the federal agency’s exclusive jurisdiction over the prediction market space. Trump has repeatedly criticized state officials for attempting to enforce local gambling rules on federally registered platforms. He emphasized that fragmented state-by-state regulation would harm national financial markets and push innovation overseas to unregulated foreign competitors. This strong political backing from the executive branch has bolstered the federal agency’s legal defense in ongoing court battles over jurisdictional authority.
The federal drive for tighter market rules has also gained urgency following several high-profile insider trading scandals. Recently, federal prosecutors charged a U.S. Special Forces member with using confidential military intelligence to win $400,000 on Polymarket by betting on the capture of Venezuelan leader Nicolas Maduro. Additionally, a Google systems engineer allegedly leveraged nonpublic corporate data to net $1.2 million in prediction trades. These incidents, alongside anonymous accounts that generated $2.4 million in profits from geopolitical event contracts, have forced regulators to prioritize market transparency.
In response to these mounting concerns, prediction platforms are taking proactive steps to upgrade their internal compliance systems. Kalshi recently implemented strict new account-verification processes for high-risk traders and introduced a whistleblower tool to report suspicious activity. The company will also deploy an automated risk-monitoring system to identify unusual betting patterns that could point to insider information. As the commission opens its proposed draft for public feedback, the final rules will determine if prediction markets can balance rapid expansion with rigorous regulatory compliance.
