Cracks in the AI

For two years, Wall Street cheered every dollar Big Tech poured into AI. This week, the mood flipped. Investors dumped tech stocks as the four biggest spenders showed how much cash their AI ambitions are burning. Quick Facts Why Investors Are Nervous Earlier in the AI boom, big spending read as confidence. Now the market is focusing on three problems: negative free cash flow (spending more cash than a company earns), rising debt and uncertain returns. The fear isn’t that AI demand is fading. It’s that the cost of meeting that demand may outrun the payoff. Alphabet: Spending Heavily While Search Slows Alphabet reported negative free cash flow of $9.1 billion in the third quarter, its second straight quarter in the red. Quarterly capex hit $51.4 billion, and the company expects to spend up to $205 billion this year, with more to come in 2027. There’s a second problem. Google’s AI Mode in Search is a hit, but it’s also eating into the core business. Search advertising, roughly half of revenue, grew just 12%, its slowest pace in five quarters. Google is spending billions on technology that could undercut the very product funding it. Amazon: Cloud Boom, Cash Drain Amazon posted negative free cash flow of $42.4 billion over the last 12 months, compared with positive $14.8 billion the year before. It expects $220 billion in capex this year. AWS revenue climbed 39%, yet Amazon’s stock still dropped 7% after earnings. Meta: Burning Cash on AI Agents Meta recorded negative free cash flow of $2.1 billion in the quarter and guided to as much as $145 billion in capex. Mark Zuckerberg said its new Muse AI agent is compute-intensive to run. Ad revenue grew 26%, but Meta’s stock still fell 10% last week. Microsoft: The Exception Microsoft stood alone with positive free cash flow of $18.6 billion. It spent $45.2 billion on capex, below its $50 billion projection, and blamed delays in capacity from third-party providers. That unplanned slowdown hit smaller companies that rent out AI computing power, whose shares sank. The Debt Pile Is Growing Profits alone aren’t funding the buildout. According to S&P Global Market Intelligence, Microsoft, Alphabet, Amazon, Meta and Oracle raised a combined $326 billion in debt in 2026. That’s triple the 2025 total, a sign of how aggressively the hyperscalers are borrowing. Chip Stocks Take a Beating The anxiety spread to semiconductors on Friday. Nvidia fell 4%, Broadcom dropped more than 5% and Qualcomm slid 11%. What It Means for Anthropic’s IPO The jitters could complicate Anthropic’s highly anticipated public debut, since the company needs enormous amounts of compute to grow. The Financial Times reported that Blackstone warned investors Anthropic might not qualify for an investment-grade rating after going public, which could leave it more reliant on hyperscalers and third parties for infrastructure funding. Demand Is Still Strong Google, Amazon and Microsoft all saw cloud gains. The worry isn’t demand. It’s the price tag.
