AI startup Prometheus has leased six floors at the One Harrison building in San Francisco, marking a significant move to consolidate its headquarters. The expansion comes as the local commercial real estate market sees office vacancy rates reach 27.7% in the third quarter of 2026.
Why it matters
The lease signals a shift toward office spaces designed specifically for hardware-intensive AI and robotics work, as the building offers specialized electrical capacity. This move reflects a broader trend of high-growth tech firms securing massive, specialized footprints to support scaling operations.
The One Harrison office building spans 180,000 square feet, following an $80 million acquisition by The Sobrato Organization. Prometheus, valued at $41 billion, currently operates out of a 30,000-square-foot office at 101 Mission Street.
The players
Prometheus
An AI startup co-founded by Jeff Bezos and Vik Bajaj that recently raised $12 billion to fuel operations.
The Sobrato Organization
A real estate firm that purchased and renovated the One Harrison office building.
The Gap
A national clothing retailer that owned and operated the One Harrison site for over two decades.
Jeff Bezos
A co-founder of the AI startup Prometheus.
Vik Bajaj

The details
The building was renovated by The Sobrato Organization to include an electrified HVAC system and a green wall, with floor plans kept open for maximum flexibility. The property was chosen for its electrical infrastructure, which is essential for the high-power demands of AI and robotics hardware. This lease allows Prometheus to bring its team together under one roof, moving away from its fragmented presence that currently includes a 100,000-square-foot industrial warehouse in West Oakland.
