This venture owns 1655 and 1725 Third Street, a pair of eleven storey Class A office buildings in the Mission Bay district of San Francisco totalling 586,208 square feet, built by Alexandria Real Estate Equities as part of the four building campus that became Uber's global headquarters and completed in 2021. Both buildings are LEED Gold certified and share a two storey cafe, a coffee and smoothie bar, an event lounge and landscaped roof decks, and they sit beside the Chase Center arena and its Thrive City plaza, about three miles south of downtown San Francisco. Alexandria developed the buildings and holds a minority position alongside affiliates of Uber Technologies and the Golden State Warriors, and in February 2025 the partners refinanced the two buildings with a 500 million dollar loan arranged by CBRE.

1655 and 1725 Third Street (unconsolidated real estate joint venture, San Francisco Bay Area - Mission Bay) files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from CBRE Secured $500 Million in Financing for Uber Headquarters in Mission Bay (CBRE), Warriors, Uber, Alexandria bag $500M loan for office complex (The Real Deal) and Uber Looks To Offload Fully-Furnished San Francisco Office It Never Occupied (The San Francisco Standard). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of 1655 and 1725 Third Street (unconsolidated real estate joint venture, San Francisco Bay Area - Mission Bay) where a holder stated one, and are missing where no holder did.
