The AI Engineer World’s Fair returns to Moscone West in San Francisco from June 28 through July 2, 2026. It is the largest technical AI conference in the world, with 29 tracks, more than 400 sessions, 100-plus expo partners, and thousands of AI engineers, founders, and VPs of AI in one building. The week opens with New Engineer Orientation on Sunday evening, a full day of hands-on workshops on Monday, then three days of keynotes and up to 12 parallel tracks.
Nobody sees all of it. The attendees who get the most out of the week are the ones who plan before they walk in. Here’s how to do that.
The Basics: When, Where, and How Long
The Fair runs four days at Moscone West, a convention venue in downtown San Francisco. Everything lives under one roof across three floors connected by a single lobby: keynotes, breakout tracks, the expo, the labs, networking, and coffee. An attendee is never more than an escalator ride from the next session. You can find all the necessary details on both the AIE World Fair’s site or the conference app.
The real start of the conference is the evening of Sunday, June 28, when badge pickup and New Engineer Orientation open. Main programming hours run roughly 8 a.m. into the early evening on conference days, with the program grid spanning into the night for receptions and side events. Expo access covers three and a half days, from June 29 through July 2.
