CFTC Directive Requires Prediction Markets to Replace American Odds with Percentages
TL;DR — CFTC’s Aug. 7 memo requires prediction platforms including ProphetX, Novig, DraftKings, FanDuel, and Kalshi to replace American odds with percentages to avoid misleading users. Traders have complained on Discord and X, but the underlying contracts and liquidity are unchanged. Adaptation is anticipated ahead of the NFL season.
SCCG Take — The directive sharpens the regulatory line between prediction markets and sportsbooks, bolstering legal standing for compliant operators while surfacing short-term user friction that must be managed.
Prediction market platforms have removed American odds in favor of percentage-based pricing after a directive from the U.S. Commodity Futures Trading Commission.
ProphetX notified traders this week through its Discord channel and a similar email that the format change took effect Monday. Point spreads, moneylines, totals, and props now display as percentages. The operator cited a CFTC mandate issued nearly a month earlier as the reason for the switch.
ProphetX stated: “We understand American odds are the format many of you know best, and we don’t take this change lightly. Operating in strict accordance with CFTC guidance is what allows ProphetX to remain a legally regulated exchange, available nationwide. That status is what lets us keep bringing sports fans in this country the deepest liquidity and the best odds available anywhere, and we intend to keep it that way.”
The Aug. 7 CFTC memorandum warned that American odds “used by casino gambling bookmakers 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.”
Trader Pushback and Platform Responses
Traders responded with immediate frustration. Comments on Discord included “Give me American odds back” and requests for browser extensions to restore the prior format. One user on X asked: “Will you ever add American odds back?”
Novig, which launched a month ago, implemented the change last week ahead of the deadline. Users there wrote that “Taking away american odds is huge L” and “I don’t like it.” The platform posted a link to an odds calculator on Discord to assist the transition. Similar notices appeared for DraftKings, FanDuel, and Kalshi users.
The reactions have been prominent on social channels even if not universal. As reported by Gambling Insider, the core product and liquidity remain unchanged. The adjustment affects only how prices are displayed.
Regulatory Distinction and Near-Term Outlook
The CFTC action forms part of ongoing efforts to distinguish prediction exchanges from higher-margin sports betting apps amid legal challenges that could reach the U.S. Supreme Court. Platforms must demonstrate they operate as regulated markets rather than betting interfaces.
With the NFL season beginning next week, traders will encounter the new format during high-volume events. Initial resistance mirrors past objections to American odds when sports betting expanded, yet users ultimately adapted to those conventions. Operators will track whether the percentage display alters engagement or if the mandated clarity supports broader market access.

The CFTC just drew a bright line between prediction markets and sportsbooks — compliant operators gain legal clarity, everyone else faces user friction.
We've watched prediction markets mature for years, and this Aug. 7 memo is a watershed. CFTC is forcing platforms to look and feel different from books — protecting their regulated status but risking short-term churn. Operators who nail the UX transition and educate users fast will hold share into NFL season.
