In the two weeks following President Donald Trump's "Liberation Day," Bay Area tech billionaires collectively lost $44 billion amid market volatility spurred by shifting tariff policies. Meta's Mark Zuckerberg experienced the largest individual loss, with his net worth declining by $30.7 billion. In contrast, Elon Musk's fortune increased by $26 billion during the same period. Meanwhile, the tech real estate market in Silicon Valley saw notable activity: LinkedIn acquired a 120,000-square-foot research and development building near its Sunnyvale headquarters for $75 million in cash. Additionally, Presidio Bay Ventures emerged as the highest bidder for the approximately 17-acre former U.S. Geological Survey campus in Menlo Park, purchasing it for $137 million. Despite return-to-office mandates, San Francisco continues to lag behind other major U.S. cities in employee return rates, with Houston leading at 74.3% of pre-pandemic levels. The region's tech sector remains active, with companies like SAP expanding their presence by leasing new office space in Palo Alto's Stanford Research Park.
