CFTC warns prediction markets against using sportsbook-style odds
The US Commodity Futures Trading Commission (CFTC) has warned prediction market operators against displaying contract prices in a typical sportsbook format.
On 7 August, the CFTC’s Division of Market Oversight and the Market Participants Division warned registered entities and individuals against displaying event contract pricing “in “American” odds format used by casino gambling bookmakers,” noting this “is likely to mislead market participants about the nature of the transaction and may deprive users of access to indicia of market depth and pricing impact.”
The guidance comes as prediction market operators have been expanding their sports contracts offerings. Sportsbooks, governments and legislators have issued concerns about the contracts and the fact that they’re not falling under state or tribal sports wagering laws and oversight.
The CFTC specifically warned that prediction market operators like Kalshi and Polymarket have a “responsibility not to mislead consumers, including the obligation to display clear and accurate pricing information for derivatives products.”
In addition to being published on the CFTC’s website and circulated to agency employees, the letter was also sent to futures commission merchants and associated prediction market brokers.
The recent measure is part of a wider effort by the CFTC to introduce tighter regulation on prediction markets. In June, the agency introduced a proposed framework to determine whether event contracts should involve activities that are prohibited under the Commodity Exchange Act’s Special Rule, including gaming, unlawful conduct, terrorism, assassination and war.
Prediction market operators and the CFTC argue that the products are federally regulated derivatives. Recently, the CFTC has taken legal action against states seeking to restrict prediction markets, including Kentucky and New Mexico.

The Backstory
Federal rules collide with state gambling lines
The Commodity Futures Trading Commission’s warning against sportsbook-style odds is the latest sign that prediction markets have moved from a niche derivatives category into the center of the U.S. gambling policy fight. The agency is not merely policing typography or user-interface choices. By telling registered entities and intermediaries not to display event-contract pricing in American odds, the CFTC is drawing a sharper line between federally regulated derivatives and products that look to consumers like sports bets.
That distinction has become harder to maintain as operators expand beyond elections and economic indicators into sports-related contracts. Platforms such as Kalshi and Polymarket describe their products as event contracts listed under federal commodities law. State regulators, tribal gaming interests and sportsbook operators increasingly say the same products function as sports wagering without the licensing, tax obligations and responsible-gaming requirements that apply to regulated sportsbooks.
The CFTC’s guidance fits into a broader push to clarify how event contracts should be treated under the Commodity Exchange Act’s Special Rule, which allows the agency to review or prohibit contracts tied to gaming, unlawful activity, terrorism, assassination and war. The odds-format warning therefore serves two purposes: It signals concern that customers may misunderstand derivatives as gambling products and it gives the agency another tool as it tries to preserve its jurisdiction amid pressure from states and Congress.
A rush for CFTC licenses changes the competitive map
The stakes have risen because major financial, crypto and gambling-adjacent companies are moving toward the federally regulated prediction-market channel. Kraken’s acquisition of CFTC-licensed Small Exchange showed how valuable a designated contract market license has become for companies seeking a compliant U.S. derivatives platform. The crypto exchange said the deal would support a U.S.-native derivatives business, and it later confirmed interest in prediction markets.
That transaction followed a pattern: Companies that want national reach are looking to the CFTC framework rather than state-by-state gambling approvals. For crypto-native businesses, the license offers regulatory legitimacy. For gaming companies, it could offer access to large states where sports betting remains unavailable. For exchanges, prediction markets create a retail-facing growth category at a time when event-based trading is drawing mainstream attention.
Flutter Entertainment’s move in the same direction underscored the point. Analysts described Flutter’s partnership with CME as a logical early step that could position FanDuel for sports-related event contracts if the regulatory environment permits. The initial products were not framed as sports contracts, but the infrastructure could be adapted quickly. That possibility matters because FanDuel and DraftKings already dominate legal online sports betting and have the brand reach to reshape prediction markets if they enter aggressively.
Sports contracts revive old regulatory fights
The industry’s current trajectory also reflects unresolved disputes from earlier attempts to list sports event contracts. RSBIX, in partnership with Matchbook, recently applied to launch sports event contracts through the CFTC. The bid revived a previous effort involving Eris Exchange to list NFL futures contracts, which was withdrawn in 2020 after opposition from the NFL and the American Gaming Association and regulatory scrutiny from the CFTC.
RSBIX’s return shows how much the market has changed. Five years ago, sports event contracts appeared too politically sensitive to move forward. Now, Kalshi has pushed sports-related markets into live regulatory disputes, Polymarket has been cleared for a U.S. return through CFTC no-action relief and several companies are exploring federal routes to event trading. The core legal question remains the same: When does a risk-transfer contract become gambling?
Sports deepen that question because pricing formats, point spreads and proposition-style markets can make contracts resemble sportsbook products. The CFTC’s concern about American odds addresses that perception directly. In derivatives markets, prices typically convey probability, liquidity and depth. In sportsbooks, odds communicate payouts and betting lines. If event contracts are presented in the latter format, the agency says customers may be misled about the nature of the transaction and lose information needed to assess market impact.
States press their case against federal preemption
State regulators have not accepted the idea that CFTC registration alone shields prediction-market operators from gambling laws. Michigan, Nevada, New Jersey, Massachusetts, Kentucky, New Mexico and other jurisdictions have pushed back against sports-event contracts or argued that they amount to unlicensed wagering. The conflict has produced litigation and agency actions on both sides, with the CFTC asserting that registered derivatives exchanges must operate as national markets.
The Michigan dispute illustrates the tension. After a state judge temporarily blocked Kalshi from offering sports event contracts, the CFTC ordered the company to honor pending trades from Michigan residents. Michigan’s attorney general then criticized the CFTC’s order involving Kalshi trades, saying it undermined the state’s authority to protect residents and enforce sports-betting and tax laws. The CFTC’s position was that allowing trades to be canceled based on a customer’s state would conflict with federal requirements for impartial access.
That is the central federalism dispute. Prediction-market operators say they are operating under a national commodities regime and should not be forced into a patchwork of state gambling restrictions. State officials say companies cannot avoid local consumer-protection, licensing and tax rules by relabeling sports bets as derivatives. Tribal stakeholders add another layer, arguing that prediction markets may interfere with compact rights and long-standing tribal gaming prerogatives.
Congressional pressure narrows the agency’s room
The fight has moved beyond courts and agencies into federal budgeting. Democratic senators have sought to restrict the CFTC’s ability to spend money challenging state and tribal gambling enforcement actions against prediction markets. Their effort to block CFTC funding tied to prediction-market cases is narrower than previous proposals to ban sports, election and government-action contracts outright, but it could have practical force if adopted.
The funding push reflects concern that the CFTC is becoming an ally of operators seeking to bypass state gambling controls. It also shows how politically sensitive the category has become. Lawmakers from states with casinos, online betting, tribal gaming or active enforcement disputes have incentives to defend existing regulatory structures. At the same time, the CFTC is under pressure to provide clarity for registered entities and avoid ceding derivatives oversight to state gambling regulators.
This political backdrop helps explain the agency’s focus on presentation and disclosure. A warning about odds formats is less sweeping than a ban on sports contracts, but it can still influence market behavior. By requiring prediction markets to look and function more like derivatives exchanges, the CFTC may be trying to reduce claims that the products are disguised sportsbooks while preserving its authority over event-contract markets.
Consumer perception becomes the next battleground
The format dispute is likely to matter because the commercial opportunity depends on mainstream users. If customers see a contract priced like a bet, marketed around sports outcomes and offered in states without legal sports betting, state regulators will view the product as gambling regardless of its federal listing. If the same contract is displayed as a derivative with transparent order books, probability-based pricing and market-depth information, operators have a stronger argument that they are offering financial instruments.
That difference may shape which companies can scale. Established sportsbooks have customer bases and risk-management experience but must protect state licenses and relationships. Crypto exchanges and prediction-market startups may move faster through federal channels but face trust, compliance and political challenges. Traditional exchanges have regulatory credibility but may be cautious about sports products that invite scrutiny.
The CFTC’s warning does not resolve whether sports event contracts are lawful nationwide or whether states can enforce gambling laws against federally registered platforms. It does, however, mark a tactical shift. The agency is signaling that prediction markets cannot borrow the language and visual cues of sportsbooks while insisting they are purely derivatives markets. As more companies seek CFTC licenses and more states challenge sports contracts, how these products are presented to consumers may become as consequential as how they are classified in law.
