Gamescom 2026 runs Aug. 26–30

gamescom has set its 2026 dates for Aug. 26 through Aug. 30 at Koelnmesse in Cologne, according to the event’s official site and Koelnmesse’s trade-fair calendar. Opening Night Live, the Geoff Keighley-hosted kickoff show that precedes the main exhibition, is scheduled for Aug. 25 and will be streamed live. For U.S. viewers, the timing translates into an afternoon start. The official gamescom Opening Night Live page lists the show for 8:00 p.m. on Aug. 25 in Cologne, and that corresponds to 2:00 p.m. Eastern in the United States on the same date. ### When does the main show actually start? Koelnmesse lists gamescom 2026 from Aug. 26 to Aug. 30 in Cologne on its official trade-fair calendar. (gamescom.global) The gamescom site also presents the 2026 edition as the main event running across those five days. Aug. 26 falls on a Wednesday in 2026, putting the show on its usual late-summer schedule and ending Sunday, Aug. 30. (gamescom.global) Third-party event guides say Wednesday is geared toward media, trade visitors and some Wildcard access, with the broader public footprint building from Thursday, though the official pages surfaced here do not spell out the full public-day breakdown. (gamescom.global) ### What is happening on Aug. 25 before the halls open? Opening Night Live is set for Aug. 25 at Koelnmesse, according to gamescom’s official program page and exhibitor information page. The event page says the show will feature trailers, gameplay reveals, celebrity guests and a first look at highlights from gamescom 2026. (koelnmesse.com) Geoff Keighley is identified by gamescom as the host and producer of Opening Night Live. The official page also says tickets for the 2026 show are already sold out, while the livestream remains available on Aug. 25. ### Where does the 2:00 p.m. Eastern time come from? The official gamescom page gives the local start time as 8:00 p.m. in Cologne on Aug. 25. (gamescom.global) In late August, Cologne observes Central European Summer Time, which is six hours ahead of U.S. Eastern Daylight Time, making the U.S. start 2:00 p.m. Eastern. That matches the timing cited in U.S.-focused schedule coverage referenced in the source briefing. The official listing is the clearest source for the local start, and the time-zone conversion yields the U.S. afternoon window. ### Is anything else tied to the event week? Koelnmesse and gamescom dev list the developer conference ahead of the main show. (gamescom.global) Koelnmesse’s calendar places gamescom dev on Aug. 23-25 in Cologne, while the gamescom dev ticket page says business tickets cover access to both gamescom dev and gamescom from Aug. 26-28 for the main event’s business area. The official accreditation page for Opening Night Live also points to Aug. 25 as the in-person show date, reinforcing that the showcase sits immediately before the exhibition opens on Aug. 26. ### What should people circle on the calendar now? Aug. 25 is the date for Opening Night Live, and Aug. 26-30 are the dates for the main gamescom show at Koelnmesse in Cologne. (koelnmesse.com) The official event pages now give attendees, exhibitors and viewers a fixed week to plan around, with gamescom dev beginning Aug. 23 and the main public-facing show following after the Aug. 25 kickoff broadcast.
