CME and Kalshi Spar Over Prediction Market Regulation at CFTC Hearing

A Heated Debate Over Market Standards

A contentious exchange between two major players in the prediction market ecosystem unfolded Thursday at a Commodity Futures Trading Commission roundtable in Washington, D.C. Terry Duffy, chairman of CME Group—operator of the world’s largest futures exchange by trading volume—and Luana Lopes Lara, co-founder of the crypto-native prediction platform Kalshi, engaged in a pointed back-and-forth over market manipulation risks and the regulatory treatment of newer entrants to the space.

Duffy opened the debate by expressing reservations about prediction markets, particularly regarding their susceptibility to manipulation. He emphasized CME’s track record and regulatory standing, declaring that his firm operates “the most envious markets in the world in the United States of America.” He then singled out Kalshi, sarcastically referencing one of the platform’s contracts—a Nathan’s hot dog eating contest prediction market—to illustrate his concerns about the types of events being traded. Duffy also pressed the question of why Kalshi had received approval to offer compute-based prediction contracts while CME’s own similar offerings remained pending regulatory review.

Challenging the Establishment’s Claims

Lara responded directly to being named, challenging Duffy’s position by asking whether CME itself had experienced market manipulation issues in its history. When Duffy declined to give a direct answer and instead offered to debate the matter, Lara persisted. Duffy then highlighted the scale of CME’s compliance infrastructure, noting that the legacy exchange employed more people in its regulatory division than Kalshi had in its entire organization.

Lara countered by suggesting that perhaps CME should focus on operational efficiency rather than size. Duffy retorted that credibility in markets was the real priority. As tensions escalated, moderator Walt Lukken intervened to restore order.

Lara subsequently broadened her argument, contending that the risks Duffy raised were not unique to prediction markets. According to her, every financial market—whether nascent or established, domestically based or offshore—had experienced regulatory challenges at some point. She framed regulation itself as the appropriate mechanism for identifying and addressing these issues as they emerge.

Call for Constructive Dialogue

Later in the roundtable, DraftKings CEO Jason Robins appealed to all participants to cease attacking one another’s business models and instead focus on collaborative problem-solving. The clash between Duffy and Lara underscores the mounting tension between traditional finance incumbents and newer platforms vying for regulatory approval in the prediction market space.

The dispute also highlights the broader regulatory question facing prediction markets: whether existing exchanges deserve preferential treatment under current rules, or whether newcomers should compete on a more level playing field. As federal and state regulators continue to shape policy around prediction markets, these debates over market integrity and competitive fairness are likely to intensify.

This clash matters because it reveals the structural tensions between legacy finance gatekeepers and the emerging prediction market ecosystem—a dynamic that could shape whether crypto-native platforms can compete fairly or face regulatory headwinds that protect traditional incumbents.
