xAI Co-Founder Reportedly Buys $70 Million Hillsborough Estate
A 31-year-old xAI cofounder, Yuhuai Wu, is reportedly the buyer of a 12-acre Hillsborough estate, which was sold for $70 million through a secretive LLC.

San Francisco Oakland San Jose, CA, August 12, 2026 —
HILLSBOROUGH, CA – A sprawling 12-acre estate in Hillsborough has reportedly been purchased for $70 million by Yuhuai Wu, a 31-year-old co-founder of xAI, the artificial intelligence company founded by Elon Musk.
The transaction was conducted through a secretive limited liability company (LLC), a common practice in high-value real estate deals that obscures the identity of the ultimate buyer.
Details surrounding the property itself were not extensively provided in the available information, beyond its significant 12-acre size and its location in the affluent community of Hillsborough. The sale price of $70 million places this transaction among the higher-value real estate deals in the region.
Yuhuai Wu’s role as a co-founder at xAI connects him to a prominent venture in the rapidly evolving field of artificial intelligence. The company, launched in 2023, aims to advance understanding of the universe through AI.
The specific circumstances of the sale, including the seller and the timeline of negotiations, were not detailed. The use of an LLC for the purchase means Wu’s name is not directly tied to the property’s deed in public records, though he is identified as the reported buyer.
This significant real estate acquisition by a key figure in the AI industry highlights the continued interest in high-value properties, even as the technology sector experiences various market shifts. Further details regarding the property or the transaction were not immediately available.
