Elon Musk’s brain-implant startup Neuralink has leased a vacant building in South San Francisco, marking a fresh sign of the billionaire’s renewed interest in the Bay Area tech scene.

The 144,000-square-foot property at 499 Forbes Boulevard had been vacant since 2023, after biotech firm InterVenn Biosciences pulled out of its lease amid an industry downturn, according to a report by the Business Times.

The lease adds to a growing Bay Area presence for Musk, who moved several of his companies to Texas after criticizing California’s business climate during the pandemic.

Tesla and SpaceX relocated their headquarters to Austin, while Musk shuttered Twitter’s San Francisco offices after renaming the platform X Corp.

Now, both Neuralink and Musk’s artificial intelligence startup xAI are expanding locally, with xAI reportedly scouting for even larger office space.

Founded in 2016, Neuralink has developed a brain-computer interface designed to help people with paralysis control devices with their thoughts. The company, valued at more than $3 billion, began human trials last year and says 12 patients worldwide now have its implant.

“The latency between a user’s intention and the system’s output is roughly 10 times faster than typical brain-to-muscle response,” president and co-founder DJ Seo told PC Mag in July.

He added that Neuralink’s robotic surgical arm “could bring its implant to the masses,” noting a backlog of 10,000 people eager to participate.

The company has partnered with hospitals in the U.K. to expand its clinical research and recently raised $650 million in new funding.

Neuralink did not immediately respond to a request for more information.
