The clock above counts down to Microsoft Build 2027 from Tuesday, May 18 to Thursday, May 20, 2027, Microsoft's flagship developer conference, expected to run as a hybrid in-person and digital event in the Seattle or San Francisco Bay Area.
Microsoft Build is the company's annual developer conference and the second-most-watched dev keynote on the calendar after Apple WWDC. Founded in 2011 as the successor to PDC and MIX, Build is the venue where Microsoft sets the developer narrative for Azure, Copilot, GitHub, Visual Studio, .NET, Power Platform, Windows, and the broader Microsoft AI Platform. The event combines a Satya Nadella opening keynote and a Kevin Scott / Scott Guthrie technical keynote with three days of breakouts, demos, certifications, and partner sessions.
Build 2027 lands in a year of significant AI and platform expansion: by early 2027, Microsoft's Azure AI Foundry, Copilot Studio, the GitHub Copilot agent, and the Windows AI Foundry runtime introduced at Build 2025 will be in their second or third generation. Build 2026 was held at Fort Mason in San Francisco with a 2,500-attendee in-person cap; the 2027 venue is to be confirmed by Microsoft, with rotation between SF and Seattle expected to continue.
Per Microsoft's stated cadence, expect Satya Nadella's opening keynote to anchor announcements across Azure infrastructure, Copilot platform expansions, GitHub Copilot agent updates, Microsoft Fabric and the data platform, .NET 11 (timed to Build 2027 if the cadence holds), and Windows AI APIs. Anticipated themes include continued investment in AI-agent orchestration, deeper Anthropic, OpenAI, and Mistral integration in Azure AI Foundry, expanded support for the Model Context Protocol (which Microsoft adopted across Copilot in 2025), and developer-tooling launches in VS Code, GitHub, and Visual Studio. Per organizer practice, expect 600+ breakout sessions, hands-on labs, and a developer expo across the venue.
Microsoft Build 2027 livestreams free on the official build.microsoft.com event site and on Microsoft Developer's YouTube channel. The Satya Nadella opening keynote starts at 09:00 PT on May 18, which is 12:00 ET, 17:00 BST, 18:00 CEST, 21:30 IST, and 01:00 JST on May 19. Most sessions are recorded and posted to Microsoft Learn within hours of broadcast, with Q&A and code samples published to GitHub. In-person registration opens via build.microsoft.com in early 2027.
Build 2027 sits in the May tech-keynote cluster alongside Google I/O 2027. The previous edition is at Microsoft Build 2026, and the November enterprise companion is at Microsoft Ignite 2027. The broader spring AI/dev calendar continues to Apple WWDC 2027.
When is Microsoft Build 2027? Tuesday, May 18 to Thursday, May 20, 2027. Where is Microsoft Build 2027 held? Seattle or San Francisco area; Microsoft confirms the specific venue closer to the event. How can I watch Microsoft Build 2027? The keynote and most sessions livestream free on build.microsoft.com and the Microsoft Developer YouTube channel; in-person passes are available via the registration site. What is the difference between Build and Ignite? Build is developer-focused (Azure, GitHub, Visual Studio, .NET, Copilot APIs); Ignite in November is enterprise-IT focused (admin, security, compliance, infrastructure).
