Microsoft Build 2026

What this countdown tracks

The clock above counts down to Microsoft Build 2026, confirmed for Tuesday, June 2 at 09:00 PT at the Fort Mason Center in San Francisco, with a second day on June 3 covering deep-dive developer sessions.

About this event

Microsoft Build is the company's annual developer conference and the moment Microsoft anchors its AI, cloud, productivity, and Windows direction for developers. After running in Seattle for several years, Build moved to San Francisco for 2024 and has remained there. The 2026 edition is capped at roughly 2,500 in-person attendees at Fort Mason Center, with a global livestream component and free on-demand sessions following the live broadcast.

Satya Nadella opens the event with the company's strategic keynote, followed by Kevin Scott on Microsoft's AI platform vision. Subsequent days run sessions on Azure, GitHub, .NET, Visual Studio, Windows AI, Microsoft 365 Copilot, Power Platform, and Microsoft Fabric. Build is the venue at which Microsoft typically details Azure AI Foundry roadmap, GitHub Copilot evolution, and Windows AI runtime updates.

What to expect

The 2026 keynote is expected to focus on the next phase of Microsoft's AI agent platform, including Azure AI Foundry agent orchestration, Copilot Studio updates, and GitHub Copilot's coding agent. Updates to .NET, Visual Studio, and Windows AI Foundry are likely. Microsoft Fabric and Power Platform announcements will continue the company's push to consolidate enterprise data tooling. Expect new model availability across Azure OpenAI Service, deeper Anthropic Claude integrations after the 2024 partnership, and expanded NLWeb open-standard adoption. Hardware announcements at Build are uncommon, but Surface Copilot+ PC roadmap or Windows on Arm momentum may surface.
