The clock above counts down to Google I/O 2027, expected on Tuesday, May 11 at 10:00 PT at the Shoreline Amphitheatre in Mountain View, California, following Google's long-running mid-May Tuesday-morning keynote pattern.
Google I/O is the company's flagship developer conference and the calendar moment at which Google clarifies its AI, Android, Cloud, and Pixel narratives for the year. The Shoreline Amphitheatre, located across the road from Google's Mountain View campus, has hosted the event since 2016, and the format has run as a hybrid in-person and online conference since 2022. CEO Sundar Pichai opens the keynote, followed by executives from DeepMind, Android, Search, Cloud, and Workspace.
The two-day programme features more than 200 sessions, codelabs for in-person attendees, sandbox demos, and one-on-one consultations for developer relations teams. Most session content is released on demand within hours of the live keynote, and Google holds regional I/O Connect follow-up events later in the year for developers unable to travel to Mountain View.
The 2027 keynote is expected to introduce a next-generation Gemini frontier model along with updates across Pro, Flash, and on-device Nano tiers. Android 18 developer preview, Wear OS updates, Pixel software previews, and new AI Studio and Vertex AI capabilities are all likely. Expect continued evolution of Project Astra agentic features, Veo and Imagen video and image models, and NotebookLM. Google Cloud announcements are increasingly anchored at I/O ahead of Google Cloud Next in spring, so expect Vertex AI agent platform updates and AI infrastructure roadmap detail. Pixel hardware reveals at I/O are unusual, with the major Pixel cycle reserved for August.
The keynote is expected to stream free on io.google, Google Developers' YouTube channel, and Android Developers' YouTube channel. A 10:00 PT start translates to 13:00 ET, 18:00 BST, 19:00 CEST, 22:30 IST, and 02:00 JST on May 12. The opening keynote runs roughly two hours, followed by the Developer Keynote and a flood of recorded sessions across Android, AI, web, and Cloud tracks. Sessions can be filtered by track and skill level on the I/O site.
I/O sits ahead of Microsoft Build 2027 and Apple WWDC 2027, and is a curtain raiser for Google's own Pixel 12 launch in August. For Google's full annual calendar, see the Google keynote hub.
