Zuckerberg Loses Nearly $20 Billion as Meta AI Spending Concerns
Mark Zuckerberg’s estimated wealth fell by nearly $20 billion in two trading sessions.
This happened mainly because Meta’s stock price dropped.
Zuckerberg owns about 13% of Meta, so changes in the company’s share price affect his estimated fortune.
Investors are worried that Meta and other technology companies may spend too much money building AI systems.
Goldman Sachs said the companies would need very large AI revenues just to break even on that spending.
Meta’s stock had risen strongly in September before the recent decline.
The company is still expanding its AI products, including its Muse assistant.
Meta also hired MongoDB chief executive CJ Desai to build an enterprise AI business for companies and developers.
Mark Zuckerberg’s estimated fortune fell nearly $20 billion across Friday and Monday as Meta shares declined.
His wealth dropped $10.9 billion on Monday to $246.7 billion, following an $8.9 billion decline Friday.
Meta shares fell after Goldman Sachs warned that AI infrastructure spending could require enormous future revenue to break even.
Meta’s 2026 capital expenditure could reach $145 billion, intensifying investor scrutiny of its AI investments.
Meta hired MongoDB CEO Chirantan “CJ” Desai to lead a new enterprise AI business.
