BlizzCon 2026 starts today with free stream and 10:30 a.m. PT opening

BlizzCon 2026 begins Saturday, September 12, at the Anaheim Convention Center in California and continues through Sunday. The opening ceremony is scheduled for 10:30 a.m. Pacific Time, which is 2:30 p.m. in Brasília. Blizzard has confirmed that coverage will be available free of charge through its official YouTube, Twitch and Battle.net channels.

The opening is expected to carry the event’s main company-wide announcements, but Blizzard has not published a complete list of reveals in advance. Any game, expansion or release date not named in the official schedule therefore remains an expectation rather than a confirmed item. What is established is a sequence of panels for the publisher’s largest franchises, joined by competitions and in-person activities across the two-day convention.

What is confirmed for day one

The opening ceremony occupies the 10:30–11:45 a.m. Pacific slot, or 2:30–3:45 p.m. in Brasília. The program then splits across different stages and channels. “What’s Next” presentations for World of Warcraft and Overwatch are listed from noon in California, or 4 p.m. in Brasília. The Diablo panel is scheduled for 1:45 p.m. Pacific, which is 5:45 p.m. in Brasília.

Those sessions are the confirmed opportunities for development teams to discuss the current state of each franchise and what comes next. Their presence on the schedule does not guarantee that every Blizzard project will appear, or that every panel will include a release announcement. That distinction matters because the run-up to the convention produces speculation, while the published agenda confirms only times, brands and broad formats.

The program also includes tournaments and competitive showcases tied to World of Warcraft, Overwatch, Hearthstone and Blizzard’s classic strategy universes. Because simultaneous activities can appear on separate channels, viewers following one franchise should check the official schedule during the event. Organizers say the timetable is subject to change and will be updated after the opening ceremony.

Where to watch and what will not be streamed

Online access does not require a digital ticket. Blizzard lists YouTube, Twitch and Battle.net as the official destinations for free coverage, although the selection of sessions may differ from one channel to another. The viewership page collects the links and identifies content that offers eligible accounts in-game rewards. Requirements vary by platform and game, so linking a Battle.net account and checking each campaign’s terms helps avoid treating time spent watching as an automatic reward.

Not everything happening in Anaheim will be shown online. According to the official guide, musical performances are reserved for the in-person audience. Some convention-floor activities, developer meetups and exhibition experiences also fall outside the video schedule. The broadcast is built around the opening ceremony, selected panels and the main tournaments.

Why the opening sets the agenda

At a convention divided among several games and stages, the opening ceremony works as an editorial index: it establishes which projects receive the spotlight and provides context for the sessions that follow. Blizzard says a fully updated version of the schedule and event map will be available only after the ceremony. In practical terms, the 10:30 a.m. Pacific opening is the clearest entry point for viewers at home, followed by a choice of channels based on the franchise they want to track.

BlizzCon 2026 therefore arrives with a clear mix of confirmed facts and details deliberately held for the stage. The dates, venue, free streaming options and panels for World of Warcraft, Overwatch and Diablo are confirmed. The specific content of any announcements becomes fact only when Blizzard presents it during the event.
