Yuhuai Wu, a 31-year-old xAI cofounder, appears to be the buyer of a $70 million Hillsborough estate via a secretive LLC, just months after his departure from xAI following its acquisition by SpaceX.

Yuhuai Wu, a 31-year-old cofounder of xAI and key developer of its Grok chatbot, appears to be the buyer behind Northern California's largest home sale this year: a $70 million, 12-acre estate in Hillsborough. The purchase, reported by the SF Standard, was made through a secretive entity named "Daikon no Hana Capital LLC," raising questions about the opaque movement of wealth from recent tech windfalls.

Property records list "Daikon no Hana Capital LLC" as the owner of the sprawling Hillsborough property. However, the buyer was represented by Jia Xu of J West Investments, an agent who also handled Wu's $12 million Los Altos Hills home purchase last year. Further linking Wu to the transaction, the LLC is managed by Steven D. Anderson, a Burlingame-based estate planning attorney who placed Wu's Los Altos Hills property into a family trust just a week before the Hillsborough sale closed on August 6. No direct public filing lists Yuhuai Wu as the owner of "Daikon no Hana Capital LLC."

Wu's apparent acquisition follows his departure from xAI in February, shortly after Elon Musk's AI venture was acquired by SpaceX. The all-stock transaction valued xAI at an estimated $250 billion, contributing to a combined entity with SpaceX worth $1.25 trillion. Wu, who also goes by Tony, announced his resignation around February 9, just days after the acquisition. His move into ultra-luxury real estate underscores the significant, and often rapidly realized, personal wealth generated by high-stakes Bay Area tech deals.

While the SF Standard's detailed reporting points strongly to Wu as the ultimate buyer, the use of a limited liability company obscures direct ownership in public records. The full financial implications of Wu's xAI exit, specifically the size of his payout, remain undisclosed in public filings. This sale further solidifies the Bay Area's position as a magnet for tech-driven wealth, with high-value real estate transactions frequently occurring through discreet entities.
