**[xAI Co-Founder Wu Yuhua May Spend $70 Million to Purchase Luxury Mansion in California]** BlockBeats News, August 16: According to *The San Francisco Standard*, the actual buyer of a $70 million, 12-acre luxury mansion located in Hillsborough, California, may be 31-year-old xAI co-founder Wu Yuhua. This transaction marks the highest-priced residential sale in Northern California so far this year. Property records show that the estate, located at 3000 Ralston Avenue with a main residence spanning approximately 12,000 square feet, is registered under "Daikon no Hana Capital LLC." However, Jia Xu, the broker representing the buyer in this transaction, had also facilitated Wu Yuhua's $12 million purchase of a Los Altos Hills residence last year. Additionally, the managing attorney of this LLC transferred Wu Yuhua's previous residence into a family trust about a week before this transaction was finalized. Wu Yuhua is likely the actual buyer of this property. Wu Yuhua co-founded xAI with Elon Musk and others in 2023 and participated in the development of Grok. In February of this year, shortly after xAI was acquired by SpaceX in an all-stock transaction valued at $250 billion, Wu announced his departure from xAI. The estate sold includes a main residence with six bedrooms, a guesthouse spanning approximately 4,600 square feet, as well as amenities such as a tennis court, a nine-hole golf course, a 150-seat outdoor amphitheater, a koi pond, and a 2,100-gallon saltwater aquarium. The property was initially listed for $88 million last fall, later reduced by $10 million, and ultimately sold for $70 million. [Original Link]
