The U.S. Commodity Futures Trading Commission (CFTC) has cautioned prediction market platforms against using American-style “moneyline” betting odds, according to Bloomberg. The warning comes as the CFTC addresses ongoing legal challenges related to whether certain prediction markets function as unlawful sports betting operations. The regulator’s position, as described in the coverage, is that applying casino-style odds formats—specifically the American odds convention commonly used for gambling—could increase legal and regulatory risk for these platforms. The reports indicate the guidance is part of the broader scrutiny the CFTC is facing while it works to defend its regulatory approach in court. The CFTC’s message does not change the core structure of prediction markets, but it directs platforms to modify how they present pricing or odds to users. The Block and Bloomberg both report that the CFTC told some platforms to stop using American-style odds, framing the caution in the context of active litigation over whether the activities constitute illicit sports betting.
