Wondering about the openai devday 2026 date? The quick version is just below: it’s Tuesday, 29 September 2026 — one week from today — at Fort Mason in San Francisco, and the opening keynote streams free. I’ve pulled every confirmed detail from OpenAI’s official DevDay page (checked 22 September 2026) so you know exactly what’s happening, whether you can still get in, and how to watch without a ticket.
Short answer:
- Date: Tuesday, 29 September 2026, per OpenAI’s official DevDay site.
- Location: Fort Mason, San Francisco.
- Keynote: 10:00 a.m. Pacific, featuring Sam Altman — livestreamed free; other sessions are recorded and posted afterwards.
- Can you still attend? In-person applications are now closed (registration was $650, with scholarships available).
- Not in San Francisco? DevDay Exchange satellite events run in Bengaluru, Tokyo, Seoul, Paris, Berlin, London, São Paulo and Mexico City.
Openai devday 2026 date: what’s officially confirmed
Everything in this section comes straight from OpenAI’s official DevDay page at devday.openai.com, which I fetched today, 22 September 2026 — no rumours, no leaks.
- When: Tuesday, September 29, 2026.
- Where: Fort Mason, San Francisco.
- Schedule: breakfast from 8 a.m., the opening keynote at 10:00 a.m. featuring Sam Altman, technical sessions on APIs and tools, hands-on demos and workshops, and a closing reception from 4:45 p.m. to 7 p.m.
- Tickets: in-person applications are closed. Registration cost $650, application statuses were sent by late July, and invitees had 14 days to register before their spot was offered to the waitlist. Scholarships covering registration — and potentially travel and accommodation — were available.
That timing puts the keynote at 6:00 p.m. UK time on the 29th, which is very watchable with a cup of tea.
How to watch the keynote live (free)
You don’t need a ticket for the part that matters most. Per the official page, the opening keynote will be livestreamed for free, and the remaining sessions will be recorded and posted afterwards. My playbook for keynote day, refined over the last few DevDays:
- Watch the 10 a.m. Pacific keynote live — pricing and API announcements always land there first.
- Skim the developer docs the moment new endpoints or models appear; the gap between “announced” and “first tutorial ranking in Google” is where the SEO opportunity lives.
- Catch the recorded technical sessions in the following days for the details the keynote glossed over.
If you can’t make San Francisco, OpenAI is also running DevDay Exchange satellite events in eight cities: Bengaluru, Tokyo, Seoul, Paris, Berlin, London, São Paulo and Mexico City. For UK readers, the London Exchange is the closest you’ll get to the room this year.
For context on what OpenAI has been shipping in the run-up, my recent breakdowns of the OpenAI Agents API and ChatGPT sponsored agents cover the platform’s current direction — DevDay announcements tend to build on exactly these threads.

Why the openai devday 2026 date matters for SEOs and builders
DevDay isn’t just a developer event — it’s the day the AI SEO meta shifts. The pattern from previous DevDays is consistent: new models and API capabilities get announced in the keynote, they hit the docs the same day, and within a fortnight the first movers have tutorials, comparisons and tools ranking for every related search. The video embedded above is my coverage of the last DevDay’s updates — watch how quickly those announcements turned into workflows.
Here’s what I’ll be watching for on the 29th, based purely on the event’s own published agenda of “technical sessions on APIs and tools” plus “hands-on demos and workshops”:
- API announcements — anything that changes cost or capability for content automation pipelines.
- Agent tooling — the sessions and workshops are where the practical detail lives, and agents are where search behaviour is heading.
- Developer platform changes — pricing, limits and access tiers decide what’s actually buildable for small teams. If you’re bootstrapping, my guide on how to use Codex for free shows the kind of workaround that usually appears within days of these announcements.
Fresh announcement days are the single best content window of the year. If you want the exact system I use to publish ranking pages within hours of a keynote — the same one running on this site — that’s what we build together in the AI Profit Boardroom, or book a free SEO strategy session and I’ll show you where it fits your niche.
