Insider activity — CMECME GROUP INC.

18 Form 4 filings for CME between 2026-09-11 and 2026-11-03, from 15 filers. 8 discretionary (6 sales, 0 purchases), 10 routine grant or withholding filings. 17 of 18 carry a dollar total (7 stated, 10 computed as shares × price), summing to $21,667,065; a multi-transaction filing without a stated total contributes only its largest transaction, so the sum is a floor and the true figure is higher. Prices ran $274 to $305.
