Microsoft Build 2026: What to expect from the June 2 keynote

Microsoft's annual developer conference opens in San Francisco on June 2, and the company has confirmed its focus well in advance. Build 2026 runs June 2-3 at Fort Mason Center, with Satya Nadella's keynote streaming from 9:30 a.m. PT. Microsoft has confirmed no Windows 12 announcement is on the agenda.

The session catalog, already live on the official website, makes the direction clear. This is an AI-first developer event built around agents, Copilot, Azure AI Foundry, and Windows local AI capabilities.

What Microsoft has confirmed

The confirmed session themes span agentic AI workflows, advances in GitHub Copilot, Azure AI Foundry platform updates, Windows-native AI development, and responsible AI tooling. Microsoft Agent 365, its enterprise control plane for AI agents, reached general availability on May 1, 2026, and Build is expected to expand on that foundation.

Azure AI Foundry is a central thread across the session catalog. Microsoft Foundry already supports models from OpenAI, Anthropic, Mistral, DeepSeek, and others, and Build sessions are expected to cover how developers route across those models, manage costs, and deploy agents into production. Cost governance has been a recurring theme from Microsoft's recent enterprise communications, and Build will address how organizations monitor token consumption and enforce responsible AI policy at the platform level.

Windows as a developer platform

Windows local AI is confirmed as a dedicated track at Build 2026. Microsoft has been building out on-device AI capabilities through Windows 11's Copilot Runtime, and Build will provide developers with the APIs and tooling to build on that stack. The May 30 Windows 11 Insider build already introduced a fully customisable Start menu and expanded local AI capabilities, pointing to where the platform is heading ahead of the keynote.

GitHub Copilot is also a confirmed focus area, with sessions covering agentic coding workflows, multi-agent support inside VS Code, and deeper GitHub-Azure integration. Copilot CLI reached general availability in March 2026, and Build is expected to extend that into multi-agent terminal workflows.

How to watch

The keynote streams free at build.microsoft.com and on Microsoft's YouTube channel from 9:30 a.m. PT on June 2. All sessions will be available on demand after the event.
