Alphabet shed roughly $500 billion in market capitalization Thursday, the second-largest single-day wipeout in stock-market history, after investors decided the company’s AI spending plan looks more like a money pit than a moat. Class A shares closed at $283.82, down 12.6%, erasing $499.8 billion in value, according to The Wall Street Journal. Only Nvidia’s $589 billion evaporation in January 2025 ranks higher.
The quarter that triggered it
Third-quarter revenue rose 25% year over year to $127.6 billion, but the top line missed consensus estimates and the composition worried the Street. Google Search, still the profit engine, grew 12%, down from 17% in the prior quarter, while capital expenditure hit $51.4 billion, largely for data centers and AI compute. Management guided for $195 billion to $205 billion in capex for the full year, with a “significant” step-up in 2027.
Cloud is booming, margins are the question
Google Cloud revenue more than doubled to $30.7 billion, up 103% and ahead of the $29.2 billion estimate, showing real demand for AI services. Yet CFO Anat Ashkenazi flagged near-term margin pressure as the unit leans on third-party capacity to keep up. The cloud beat is real; the profitability path is the variable investors are now pricing.
The broader read-across
Thursday’s drop eclipses Alphabet’s own previous record of about $275 billion in July. The episode underscores a sector-wide tension: mega-cap tech is pouring hundreds of billions into infrastructure while the market demands a clearer line of sight to sustainable returns. For now, the market has decided the receipts aren’t visible enough.
