CME Group CEO Terry Duffy called for a level playing field, opposing the granting of innovation exemptions to new market entrants like Polymarket CEO Shayne Coplan and Kalshi co-founder Tarek Mansour. He said that if the rules were different, established players wouldn't be able to compete. The Chicago Board Options Exchange (@CBOE) echoed this sentiment: "I appreciate the innovation, but if there's an opportunity to be more successful, we should all pursue it. We'll all be great competitors, we'll all be great innovators. But we shouldn't be locked into the old model."
