Brief

The 2026 World's Fair is completely sold out and promoted as "the largest AI industry expo on earth," with the Leadership track for CTOs & VP AI's, workshops, and all late-bird tickets gone. Organizers opened limited overflow expo/engineering tickets (no guaranteed seating), note 65 free side events around SF, and host New Engineer Orientation at Moscone tonight (June 28, 5–9pm).

Why it matters

The 2026 World's Fair is "completely sold out" (post published 2026-06-28) and is billed as "the largest AI industry expo on earth"; the Leadership track for CTOs & VP AI's, tomorrow's workshops, and ALL late-bird tickets are sold out.

Key details

  • There are 65 side events still free across San Francisco; organizers have opened limited overflow tickets for the expo and engineering passes — no seating guaranteed and sessions are first-come, first-served.
  • New Engineer Orientation is scheduled tonight (June 28) at Moscone from 5p–9p; organizers expect extremely heavy last-minute registration, ask attendees to help load-balance across days, and pledge to publish all AI engineering content for free on YouTube.
