US Regulator CFTC Bans Sportsbook Odds on Prediction Markets

The U.S. Commodity Futures Trading Commission (CFTC) is taking decisive action against the convergence of financial markets and sports betting. In a formal letter, the agency instructed prediction market operators to immediately cease displaying event contract prices using the traditional American odds format. The regulator fears that the use of plus and minus signs, common in sportsbooks, undermines transparency and misleads investors. Instead, providers must now utilize nominal values or percentage terms to maintain the integrity of these products as financial derivatives.

This CFTC initiative is part of a broader legal conflict. Many platforms are currently attempting to establish so-called event contracts as legitimate financial instruments. Critics and former regulators, including Gary Gensler, who headed the CFTC from 2009 to 2014, view these products more as illegal gambling disguised as financial instruments. The agency argues that displaying prices as betting odds prevents users from understanding the actual market depth and the price impact of their transactions. Thus, it is not merely a matter of aesthetics but of consumer protection and market integrity.

Numbers and facts

The CFTC has set a tight deadline for the affected companies. By August 31, regulated exchanges and brokers must confirm receipt of the notice and review their display formats. A central point of criticism is the American odds format: an odd of +200 shows the profit on a $100 stake, while -110 indicates how much one must wager to make a $100 profit. According to a study cited in the letter, these specific presentation styles encourage higher risk-taking among users. The agency intends to prevent customers from being pushed into higher-margin products through confusion.

“Displaying pricing information for derivatives products in bookmaker-style odds is likely to mislead market participants about the nature of the transaction into which they are entering and may deprive users of access to indicia of market depth and pricing impact.” - CFTC Division of Market Oversight, Joint Staff Letter

Currently, however, the agency is understaffed. Michael Selig has served as the sole acting commissioner since December, leading to criticism from the U.S. Congress regarding staffing reductions. Despite these bottlenecks, the CFTC is pursuing lawsuits in several states, including New York, New Mexico, and Kentucky, to defend its exclusive jurisdiction over these markets. Simultaneously, providers like Robinhood have already reacted by restricting their range of prediction markets to avoid potential insider trading.

Background

At its core, the dispute revolves around the definition of "swaps." Gary Gensler recently emphasized in an Indian Gaming Association webinar that Congress never intended for the CFTC to become a national betting regulator. If sports betting contracts were legally considered swaps, Gensler argued that nearly all state-level sports bets placed over the last decade would technically be illegal. This legal uncertainty has led to conflicting rulings: while platforms saw success in New Jersey and Arizona, providers like Kalshi were forced to restrict access to certain contracts in Nevada following court decisions.

Why it matters for German players

For German players, the situation is clear, as the State Treaty on Gambling 2021 (GlüStV 2021) sets strict boundaries. Such U.S.-based prediction markets do not hold a license from the Joint Gambling Authority of the States (GGL). In Germany, rigid rules apply, such as the monthly deposit limit of 1,000 Euros via the LUGAS system and a stake limit of 1 Euro per round for virtual slots. Anyone acting on platforms without a GGL license enters the illegal sector and loses all legal protection regarding payout claims. The GGL whitelist is the only reliable reference for legal play here.

What it means for GGL-licensed casinos

German licensed casinos must strictly adhere to the separation of sports betting and casino games. The current U.S. debate illustrates how vital the clear labeling of products is. While some in the U.S. attempt to disguise bets as financial derivatives, the GGL in Germany ensures that gambling remains recognizable as such. For operators, this means that any form of misleading advertising or the mixing of financial and gaming products could lead to an immediate revocation of their license. Transparency is the highest priority in the German regulated market.
