CME’s Duffy and Kalshi’s Lara Turn CFTC Roundtable Into a Battle for the Future of Prediction Markets
Tensions Boil Over at CFTC Roundtable
Thursday’s Commodity Futures Trading Commission roundtable on prediction markets was supposed to be a measured policy discussion about the future of event-based trading. It quickly became something far more combative. Inside the agency’s Washington, D.C., headquarters, CME Group Chairman Terry Duffy and Kalshi co-founder Luana Lopes Lara went head-to-head in a public confrontation over manipulation, regulatory oversight and what it means to run a credible market in the United States. The session drew executives from traditional finance, the crypto industry and the fast-growing prediction market sector, all of whom were there to debate how event contracts — derivatives tied to the outcome of real-world events — should be treated under American law. The timing only intensified the mood. State and federal regulators are already locked in a high-stakes fight over who gets to police these platforms, and Thursday’s meeting gave that conflict a very public stage. Duffy, whose CME Group operates the world’s largest futures exchange by volume, opened with a clear warning. He said he was “a lot concerned” about the path prediction markets are taking and argued that several categories of event contracts are dangerously susceptible to manipulation. He also made clear that he did not believe newer platforms should be able to operate under looser standards than institutions like CME. With the rise of platforms like Kalshi and Polymarket, the debate has moved from academic journals to the center of financial regulation. Users can wager on election results, interest rate decisions, movie opening weekends and even viral moments. Some contracts have drawn millions in volume overnight. Supporters argue that these markets generate valuable information and give ordinary people a transparent way to hedge uncertainty. Critics, including Duffy, see the same products as little more than speculative sideshows dressed up as derivatives. Those competing views were on full display Thursday, as the clear lines between traditional futures exchanges and the new generation of event-based platforms blurred in real time.
Duffy Fires a Shot at Kalshi — and Nathan’s Hot Dog Contest
Duffy did not keep his concerns at the level of broad warnings. He called out Kalshi by name, singled out one of its most unusual contracts and questioned why the company appeared able to move faster than CME in bringing certain products to market. “We’re not a bunch of carnival barkers at a circus,” Duffy proclaimed, rejecting the idea that the standards of established futures exchanges should be lowered to accommodate newcomers. “We are running the most envious markets in the world in the United States of America.” Then he reached for an example that he clearly believed made the point for him. “There’s another really economic contract that has been massively important for the United States. That’s a Nathan’s hot dog eating contest,” he said, delivering the line with unmistakable sarcasm. The implication was that a futures contract tied to an annual competitive eating event is not serious financial engineering but entertainment dressed up as trading. Duffy went on to question Kalshi’s ability to offer a compute prediction market while CME’s own proposed compute contracts remained under regulatory review. Why, he asked, should a smaller, younger firm enjoy what appeared to be an easier fast track to market than the country’s most established derivatives exchange? It was a pointed line of attack, and it did not go unnoticed. Lara, who had been sitting through the exchange, later said that she felt the direct criticism demanded a direct response. “I just wanted to respond since we were called by name here,” she said, before turning the spotlight back on Duffy and CME’s own history. The moment captured a broader tension that has defined the current moment in financial markets: established institutions insisting on guardrails, and challengers arguing that those guardrails are sometimes just barriers to competition.
Lara Fires Back: A Simple Question for CME
Lara’s counterpunch was sharp. She asked Duffy whether CME Group had ever faced allegations of market manipulation in its long and storied history. “I would actually have to ask Terry: Has CME ever had any issues with any market manipulation, any issues ever in its history?” Duffy did not answer with a simple yes or no. Instead, he proposed a debate. “If you’d like to have a debate, I’m happy to have a debate with you,” he said. Lara kept pressing him. “I’m just asking a simple answer to a question.” Duffy then responded by returning to the size of his organization. “I have more people in my regulatory department than you have in your whole company,” he said, an effort to cast Kalshi’s compliance operation as minimal by comparison. Lara shot back without missing a beat: “Maybe you should learn a bit about efficiency then.” Duffy’s answer was just as quick: “Well, maybe you should learn about credible markets.” By that point, moderator Walt Lukken had stepped in to bring the conversation back on track. But Lara was not finished with the broader argument. She acknowledged that prediction markets carry risk, but rejected the idea that risk is unique to newer platforms. “Every market has risk and every nascent market will have risks as well, and there have been issues in every single traditional market and every single exchange here, onshore and offshore,” she said. “And I think the point of having regulation is that you find these issues, you address these issues, and there’s a way to address them in a correct way.” It was a pointed reminder that incumbent institutions are not immune from scandal, even if they employ large compliance departments and have spent decades building their reputations.
DraftKings CEO Tries to Lower the Temperature
As the tension lingered, a prominent voice in the sports betting industry stepped in to urge his peers to change course. DraftKings CEO Jason Robins said the personal attacks were not helping anyone and were distracting from the substantive questions at hand. “I would just ask everybody, both in this hearing and then also in future communications, to try to refrain from taking shots at each other’s business models or decisions you may not 100% agree with,” Robins said. “That doesn’t advance the discussion.” His comments highlighted a growing frustration within the broader sector: the more time executives spend attacking one another, the harder it becomes to present a unified case to regulators. Robins is not a neutral observer in this debate. DraftKings has become a major player in legal sports betting, and the company’s own business model touches on some of the same questions that define the prediction market fight — namely, where sports wagering ends and financial speculation begins. But by appealing for civility, he also acknowledged a strategic reality. If the CFTC, state governments and Congress see an industry at war with itself, they may be more likely to impose restrictions that no one wants. The roundtable was, in that sense, a rare public glimpse into the competitive tensions inside a market that is growing faster than the rules designed to govern it. Traditional exchanges, sportsbooks, crypto platforms and prediction startups are all trying to claim the same territory, and the battle for regulatory legitimacy is every bit as important as the battle for users and market share.
A Bigger Battle: Federal Regulators vs. State Laws
To understand the stakes of Thursday’s confrontation, it helps to come back to how prediction markets actually work. Platforms such as Kalshi and Polymarket allow users to buy and sell event contracts that settle for $1 if a given outcome occurs and at zero if it does not. The price of a contract therefore functions as a probability estimate. On Myriad, a prediction market operated by Decrypt’s parent company Dastan, an event contract on “Bitcoin highs in August” has recently traded at around 59 cents on the $75,000 outcome, suggesting that the market sees a 59% chance that Bitcoin reaches that level before the end of the month. That simple mechanism has enormous appeal, but it has also created a regulatory minefield. The CFTC maintains that federally regulated event contracts fall under its jurisdiction. Individual states, however, have argued that many of these products are simply gambling and should be subject to state law. The conflict has escalated sharply in recent months. CFTC Chair Selig has repeatedly defended the agency’s authority over federally regulated prediction markets, warning states that challenged that jurisdiction in February and promising legal action. “We will see you in court,” Selig said in a video posted to X. The agency has since followed through, taking legal action against states seeking to impose their own gambling restrictions on federally regulated event contracts. In June, the CFTC proposed restrictions on certain contracts involving war, assassination and selected sports proposition bets that officials believe are particularly vulnerable to manipulation. Earlier this month, nine Democratic senators went further, urging Selig to prohibit wildfire-related event contracts out of concern that they could create incentives for arson, insider trading and disaster profiteering. Kalshi has found itself caught in the middle of these overlapping disputes. Last week, a Washington state judge ordered the company to stop offering contracts on sports, elections, politics and other events in the state, ruling that the platform likely violated state gambling and consumer protection laws. Two days earlier, however, the CFTC had directed Kalshi to keep trading, as a separate conflict developed over New York’s attempt to block its contracts. The conflicting rulings illustrate just how fractured the legal environment has become for companies trying to operate in this space.
What Comes Next for the Prediction Market Industry?
The war of words between Duffy and Lara may have made for dramatic reading, but the substantive disagreements behind it will not be resolved by a single roundtable. At the core of the debate is a fundamental question about market design: should prediction markets be fully integrated into America’s financial system, or should they be treated with caution and restricted to categories that serve a clear economic purpose? The CFTC appears to be torn between those two visions. Some officials view event contracts as a valuable source of information and a way to give ordinary people access to markets once reserved for institutions. Others worry that the rapid growth of these platforms is outpacing the agency’s ability to police them effectively. Congress, too, is beginning to weigh in, and the industry is bracing for a prolonged period of rulemaking, litigation and legislative negotiation. In the meantime, companies like Kalshi will keep trying to show that they can operate responsibly within the bounds of federal law. CME, for its part, will keep pushing for clarity about how new contracts are reviewed and approved. And the rest of the industry will have to decide whether it wants to fight for the legitimacy of prediction markets or allow internal hostilities to do the damage first. Thursday’s showdown was more than a clash between two strong personalities. It was a snapshot of an industry at a crossroads, trying to define itself before the government defines it from the outside. If regulators, businesses and public interest groups can find common ground, event contracts may become a permanent and accepted part of the financial landscape. If not, the era of rapid, unfettered expansion could come to an abrupt end. Either way, the future of prediction markets will be shaped less by hot dog contests than by the legal and political battles unfolding right now in Washington and in state capitals across the country.
