The head of CME Group, Terry Duffy, told the chairman of the Commodity Futures Trading Commission that the agency needs to do more to guard against manipulation on prediction markets as trading platforms in the space grow into multibillion dollar businesses. The exchange happened during a meeting of the CFTC's Innovation Advisory Committee, where Duffy pushed back on the commission's largely hands off approach to a wave of newly filed products.
Duffy's central complaint centered on self certification, the process that lets prediction market platforms quickly list new event contracts without upfront regulatory review. He argued that pace leaves markets more exposed to manipulation, telling the committee there have been 2,500 self certifications since the current administration took office in January of 2025, and that not one of them has been opposed.
CFTC Chairman Michael Selig pushed back directly, dismissing one of the specific examples Duffy raised as fake news and noting that the case in question did not involve products actually traded in the United States. The disagreement reflected a broader divide over how closely regulators should be scrutinizing a fast growing corner of the derivatives market.
Prediction market platforms, which the CFTC treats as derivative exchanges under its jurisdiction, have surged in popularity over the past eighteen months. Polymarket and Kalshi are the two largest players in the space, and both say they oppose insider trading and actively police activity on their own markets, arguments they have used to counter calls for heavier regulatory intervention.
The clash puts CME Group, a long established derivatives exchange operator, in the position of pushing regulators to tighten oversight of newer rivals reshaping how people bet on real world events. How the CFTC responds will shape how quickly prediction markets can keep listing new contracts, and how much scrutiny those contracts face before they go live.
