The VALORANT Champions 2026 format features 16 teams in four GSL-style double-elimination groups of four, with every group-stage series played as best-of-three. The top two teams per group advance to an eight-team double-elimination playoff bracket where most matches remain Bo3, except the lower-bracket final and grand final, which shift to best-of-five. Total maps played therefore hinges on how many series reach their maximum length—two or three maps in Bo3s, three to five in Bo5s—driven by competitive balance among the qualified rosters from Americas, EMEA, Pacific, and China. With group play opening September 24 in Shanghai and playoffs running through October 18, historical data from prior Champions events shows that even seeding and strong regional form often produce a high proportion of decisive 2-1 and 3-2 outcomes, pushing the aggregate map count higher when underdogs extend series. No late roster changes or bracket adjustments have altered the structure ahead of the event.
