Coinbase is returning to San Francisco with a new 150,000-square-foot office at the Mission Rock development, a project by Tishman Speyer and the San Francisco Giants. This move marks the company's re-entry into the city four years after it closed its local headquarters, which it had paid $25 million to exit. Despite maintaining a remote-first work model, Coinbase is establishing its largest office space in San Francisco, signaling renewed commitment to the city as a hub for growth and innovation. The development has drawn positive attention from local industry figures, highlighting San Francisco's ongoing appeal for tech and crypto companies. The Mission Rock lease underscores Coinbase's position as the leading cryptocurrency exchange in the United States and reflects broader trends of tech firms returning to or expanding their presence in San Francisco amid a vibrant ecosystem that includes events like the AI World's Fair and AI Startup School.
