Google I/O 2026 — How to Attend

📍 In-Person (Shoreline Amphitheatre, Mountain View, CA)

• Invitation-only for press and partners at the main keynote venue.
• For general developers, in-person access typically goes through a lottery-style registration via Google's official channels — but there is no guaranteed spot. You sign up, and Google selects attendees.
• Cost: Free if selected — Google does not charge admission for I/O.
• Since the event is 6 days away (May 19), the registration window for 2026 is almost certainly already closed. Lottery winners would have been notified weeks ago.

💻 Online / Virtual (Free & Open to Everyone)

• The keynotes and sessions are fully free to watch online via livestream at io.google/2026.
• You can register for free on the website to get access to the full session schedule and on-demand content.
• The Google Keynote streams May 19 at 10:00 AM PT, followed by the Developer Keynote at 1:30 PM PT.
• On May 21, on-demand sessions and codelabs drop for additional learning.
• No referral needed — just go to io.google/2026 and register with a Google account.

🌍 I/O Extended (Community Events Worldwide)

• Google partners with Google Developer Groups (GDGs) globally to host I/O Extended watch parties and local events.
• These are typically free and open to the public — check io.google/2026/community for a group near you.
