Alphabet loses $500 billion as Q3 revenue misses, capex bites

Alphabet's third-quarter report showed top-line growth that looked impressive at first glance, with total revenue up 25% to $127.6 billion. But the figure fell short of the $128.2 billion analysts had expected, and the miss appears to have triggered the sharp sell-off. The company also reported a $9.1 billion free cash flow deficit as capital expenditures of $51.4 billion outpaced operating cash flow of $42.3 billion.

Management's decision to raise the 2026 capex budget to $195 billion to $205 billion, while stressing that spending will increase significantly next year, likely reinforced concerns about the company's near-term financial sacrifices. Alphabet raised roughly $12.4 billion through common stock issuance and another $28.7 billion through debt issuance during the quarter to support its infrastructure roadmap. Issuing shares can dilute existing investors, while borrowing increases future interest payments.

The sell-off may also reflect worries about Google Search, where revenue growth decelerated to 12% from 17% in the second quarter, a slowdown that reiterates the theory that chatbots such as ChatGPT or Claude are becoming formidable alternatives. Even so, Wall Street may be overlooking Alphabet's vertically integrated AI ecosystem, including custom TPUs, Google Cloud, and DeepMind, which could be the foundation for a long-term opportunity.
