Woofun AI reports that CME Group Chief Executive Officer Terry Duffy is preparing to step down from his leadership role. This executive transition has triggered immediate market reaction, with CME Group shares retreating 4% in pre-market trading sessions.

Duffy had previously voiced 'great concern' regarding the recent regulatory approval of perpetual contracts by U.S. authorities. He argued that these instruments offer limited utility for institutional investors while exposing retail traders to disproportionate risk.

Furthermore, he stated he 'completely disagrees' with the CFTC's rapid review process for the first batch of crypto perpetual contracts, warning that such products and prediction markets are fueling a wave of retail speculation.
