Alphabet and Tesla both reported negative free cash flow in the second quarter, as surging AI capital expenditures consumed earnings.
"We expect free cash flow to remain under pressure driven by our investments in technical infrastructure," Anat Ashkenazi, Alphabet's chief financial officer, said on the earnings call.
Alphabet's Q2 free cash flow fell to negative $5.9 billion, compared with nearly $25 billion positive in the same period last year. Capital expenditures reached $44.9 billion, mostly directed at AI data centers and hardware. The company raised its full-year 2026 capex forecast to as much as $205 billion, up from a prior $190 billion ceiling, and warned spending would climb further in 2027.
Tesla's free cash flow swung to negative $1.1 billion from positive $146 million a year earlier, with capex jumping 142% to $5.79 billion. The automaker reaffirmed plans to spend more than $25 billion on capital projects this year. Chief Executive Officer Elon Musk described the spending as "a massive capital expenditure year" and compared Tesla's expansion to the fastest industrial scaling since World War II.
Alphabet shares fell about 3% in after-hours trading, while Tesla dropped 4%. The results show that even the most cash-rich technology companies are straining under the weight of AI infrastructure investment. Bank of America warned that Meta Platforms and Amazon could turn free cash flow negative as soon as this quarter, with Microsoft expected to follow by the fourth quarter.
The four largest US technology companies — Alphabet, Amazon, Microsoft and Meta — had already planned to spend more than $700 billion combined on capex this year. Alphabet's revised guidance pushes its own spending toward the top of the industry, approaching Amazon's more than $200 billion forecast. Some analysts have raised concerns about inflation in AI infrastructure costs, with higher memory chip prices making it more expensive to build out capacity.
Not all analysts are bearish. Mizuho said Alphabet's capex increase was "within market expectations" and noted cloud revenue jumped 82% from a year earlier, with Gemini model usage accelerating. "We are surprised by the after-hours decline and expect a recovery in tomorrow's trading," Mizuho analysts wrote. Keith Fitz-Gerald of Fitz-Gerald Group said Tesla is "sacrificing profitability for infrastructure" in a pattern similar to Amazon and Netflix, predicting "rich returns over the next 12 to 36 months."
The cash flow deterioration tests investor patience with the AI investment thesis. Alphabet shares had already fallen for three consecutive months before the report, while Tesla is down 17% year to date. With Meta, Microsoft, Amazon and Apple all reporting next week, the market will scrutinize whether the rest of Big Tech faces the same cash flow pressure.
