Big Tech’s $740 Billion AI Spending Boom Hits a Cash Flow Wall
Big Tech’s $740 billion AI infrastructure push alarms investors as cash flow turns negative, debt triples, chip stocks sink and Anthropic faces IPO risk.
Summary
Over the two weeks through October 30, 2026, Alphabet, Amazon, Meta and Microsoft outlined more than $740 billion of 2026 capital spending, largely interpreted as data center and chip investment. Concern over returns, debt and negative free cash flow pushed Friday’s Nasdaq down 2.9%; Nvidia fell 4%, Broadcom more than 5% and Qualcomm 11%. Alphabet declined again after Thursday’s record 12% plunge erased $500 billion of market value.
Alphabet recorded negative third quarter free cash flow of $9.1 billion for a second consecutive deficit as capex reached $51.4 billion. It expects up to $205 billion this year and further growth in 2027. AI Mode’s success is pressuring Google Search advertising, roughly half of revenue, whose growth slowed to a five quarter low of 12%. Amazon’s trailing free cash flow swung from positive $14.8 billion to negative $42.4 billion. Despite 39% AWS growth, its shares fell 7% after earnings, while planned capex totals $220 billion.
Meta posted negative third quarter free cash flow of $2.1 billion, plans up to $145 billion of capex and said free personal agent Muse is highly compute intensive, although advertising grew 26%; its stock lost 10% last week. Microsoft remained the exception with positive quarterly free cash flow of $18.6 billion and $45.2 billion of capex, below its $50 billion projection because outside providers delayed capacity, sending smaller compute rental stocks lower. S&P Global Market Intelligence data show Microsoft, Alphabet, Amazon, Meta and Oracle raised $326 billion of debt in 2026, triple last year. Cloud demand remains strong, but infrastructure costs could complicate Anthropic’s newly filed IPO after Blackstone warned it may not earn an investment grade rating, increasing its reliance on hyperscalers and third parties.
