PANews reported on September 30 that CME Group CEO Terry Duffy called for a level playing field and opposed granting innovation exemptions to new market participants, including Polymarket CEO Shayne Coplan and Kalshi co-founder Tarek Mansour. He said that if the rules were different, established players would not 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 even more successful, we should all pursue it. We will all be great competitors, and we will all be great innovators. But we shouldn't be stuck in the old model."
