Blizzard revealed Diablo V, a new open-world StarCraft shooter, World of Warcraft: Forever, and several other projects and updates. Live coverage of the event reached more than 1.76 million Peak Viewers.

BlizzCon 2026 Viewership Statistics

More than 1,400 unique channels covered BlizzCon 2026, generating over 8.8 million Hours Watched. Major broadcasters included Blizzard’s official Twitch and YouTube channels, as well as the company’s game-specific channels, including Warcraft on Twitch, World of Warcraft on YouTube, and ow_esports on Twitch.

The event also attracted significant attention from community casters. American streamer Zack “zackrawrr” Hoyt dedicated almost 12 hours of airtime to BlizzCon 2026 and reached 144,000 Peak Viewers, making it his most popular broadcast of 2026. Other creators covering the event included Thomas “sodapoppin” Morris IV, Adrien “ZeratoR” Nougaret, Joaquín “elxokas” Domínguez, and more.

World of Warcraft: Forever was one of the biggest announcements of BlizzCon 2026, while Overwatch 2 also received several major reveals. Combined with esports competition held during the event, the announcements drove substantial growth for both games on Twitch. World of Warcraft became the platform's most-watched game by Hours Watched over the weekend, while Overwatch entered the top five; both categories recorded increases of more than 620% in Hours Watched and Average Viewers.

Esports contributed to that growth as well: World of Warcraft hosted the MDI Midnight — Season 1: Global Finals, while Overwatch staged its first World Cup in three years.

Most popular game showcases in September 2026 

BlizzCon 2026 joined a crowded September calendar of major gaming showcases. While its Peak Viewers total trailed the month's leading presentations, the event still generated one of the strongest audiences among major gaming broadcasts held so far in September.
