From the Chase Center plaza along Third Street past OpenAI's and Uber's addresses to Y Combinator in Dogpatch.
The city's business registry shows a cluster of AI-company addresses around Chase Center in Mission Bay: OpenAI in several buildings, Uber on Third Street and, in Dogpatch, Y Combinator. This walk visits them from the arena plaza to the 20th Street block.
Getting there: Start at the Chase Center stop on the T Third line (UCSF/Chase Center).
Stop 1 of 7
You are at the plaza beside the arena at 1 Warriors Way, which the city's registry lists under Gsw Arena LLC from September 2020. The office buildings along Third Street are the point of this walk: the registry shows Uber at 1725 Third Street from 2020 and OpenAI at several nearby addresses.
Look for: The arena bowl behind you and the office buildings on the Third Street side.
Walk in.

Walk towards the water. The registry adds an OpenAI location at 550 Terry A Francois Boulevard in January 2026. OpenAI does not publish its office addresses, so the stops on this stretch are blocks rather than doors.
Look for: The waterfront path at the end of the block.
