Airbnb Deals Point to 374,000 SQFT at 888 Brannan, Reversing Its Planned Retreat From 850 Brannan

Newmark's third-quarter report lists a confidential 373,903-square-foot renewal and expansion at 888 Brannan St. as San Francisco's largest lease of the quarter, and Airbnb's SEC filings and CBRE's deal data show the figure matches the company's headquarters lease plus a new commitment at 850 Brannan, space it had contracted to give back at the end of 2026.
