Fortune Brainstorm AI San Francisco 2026

Fortune Brainstorm AI San Francisco 2026 is an invitation-only executive summit on the business of artificial intelligence, taking place on 7-8 December 2026 at The St. Regis San Francisco. Convened by Fortune as part of its long-running Brainstorm conference franchise, it gathers chief executives, founders, investors and senior researchers for two days of candid, working sessions on how AI is actually being deployed inside large organisations. Closing out the AI-conference calendar in the city at the heart of the industry, it functions as a year-end reckoning on what has worked, what has stalled, and where enterprise AI goes next.

A roundtable format, not a keynote parade

What distinguishes Brainstorm AI from larger trade shows is its format. Rather than a procession of stage keynotes, the event is built around intimate roundtables and small-group discussions, with a curated, capped guest list that keeps the conversation peer-level and practical. The emphasis is on genuine working dialogue — leaders comparing real deployment experiences — rather than product launches or marketing set pieces. That design makes the summit especially useful for executives who want frank intelligence on implementation realities, the kind of detail that rarely surfaces in public talks because the stakes of saying it on a main stage are too high. The smaller scale also changes who attendees actually meet: in a capped room of decision-makers, the people across the table tend to be peers wrestling with the same problems, which makes the off-record exchanges as valuable as the scheduled sessions.

The 2026 themes

The 2026 agenda centres on the hard problems of enterprise adoption rather than on model demos. Expected focal points include deploying AI effectively inside large, complex organisations; overcoming data-silo and infrastructure constraints; governance, ethics and regulatory compliance; measuring return on investment and scaling initiatives from pilot to enterprise-wide; and the workforce and change-management implications of putting AI into everyday operations. In a year defined by the shift from experimentation to accountability — boards asking where the payback is, and regulators sharpening their expectations around high-risk and general-purpose systems — those questions sit at the core of what nearly every large enterprise is wrestling with. Holding the discussion in December gives it a retrospective edge as well: by year's end the gap between the pilots that scaled and the ones that quietly stalled is visible, and the summit becomes a venue for honestly diagnosing why.

• Scaling AI from promising pilots to durable, organisation-wide deployment.
• Data, infrastructure, and the unglamorous plumbing that makes AI work in practice.
• Governance, ethics, and compliance as operational disciplines rather than slogans.
• ROI measurement, plus the workforce and change-management realities of adoption.

Who speaks and who should attend

The summit draws a notably senior roster from across the AI landscape. The 2026 line-up includes researchers and economists such as Fei-Fei Li, Andrew Ng, Erik Brynjolfsson and Joelle Pineau; founders and executives including May Habib of Writer, Arvind Jain of Glean, Aaron Levie of Box, Andrew Feldman of Cerebras, Cloudflare's Matthew Prince and Amazon's Tye Brady; investors such as Reid Hoffman, Vinod Khosla, Sarah Guo and Rebecca Kaden; and creative-technology figures like Refik Anadol. The audience is correspondingly senior: the event is built for chief executives, chief AI and technology officers, founders, venture and growth investors, and the strategists steering AI inside major companies. It is best suited to leaders making allocation and adoption decisions rather than to hands-on practitioners looking for technical workshops. The mix of researchers, operators and investors on the bill is itself part of the draw, since it lets attendees test where the academic frontier, the deployment reality and the capital flows actually line up — and where they don't.

Format and how to attend

Fortune Brainstorm AI San Francisco 2026 is an in-person, two-day gathering, and participation is by invitation and subject to approval — a deliberate filter that protects the intimacy of the discussions. Prospective attendees apply and register through Fortune's official conferences site, where the agenda and confirmed speaker list are published and updated ahead of the December dates. Because the format is small and curated, places are limited and tend to go to senior decision-makers and members of Fortune's invited community, so it is worth applying early rather than assuming late availability. For executives seeking a high-signal, end-of-year read on enterprise AI — delivered through honest peer conversation rather than vendor pitches, and set among many of the people actually defining the field — the San Francisco summit is one of the more substantive entries on the 2026 calendar, and a fitting place to take stock before the next cycle of AI strategy begins.
