xAI co-created Wu Yuhuai or spend $70 million to buy a luxury home in California

Comparatively, according to the San Francisco Standard, the actual buyer of a $70 million 12-acre mansion in Hillsborough, California, is probably Wu Yuhuai, the 31-year-old co-founder of xAI. The deal is Northern California's most expensive residential deal so far this year.

According to property records, the registered buyer of this property, which is located at 3000 Ralston Avenue and has an area of approximately 12,000 square feet, is Daikon no Hana Capital LLC. However, Jia Xu, the agent responsible for the buyer's transaction, also represented Wu Yuhuai in purchasing the Los Altos Hills home for $12 million last year; at the same time, the LLC's management lawyer transferred Wu Yuhuai's original home into a family trust about a week before the transaction was completed. Wu Yuhuai is probably the actual buyer of this deal.

Wu Yuhuai co-founded xAI with Musk and others in 2023 and participated in Grok development. He announced his departure from xAI in February of this year, shortly after xAI was acquired by SpaceX through an all-share deal at a valuation of $250 billion.

The property for sale includes a 6-bedroom main home, approximately 4,600 square feet of guest rooms, and facilities such as tennis courts, a nine-hole golf course, a 150-seat amphitheater, a koi pond, and a 2,100-gallon saltwater aquarium. The property was initially listed for $88 million last fall, then dropped by $10 million and eventually sold for $70 million.
