Both tech giants raised capital expenditure targets sharply, pushing free cash flow negative and spooking markets
Shares of both Alphabet and Tesla dropped in premarket trading on July 23 after each signaled that their appetite for AI infrastructure spending has grown considerably larger than investors were prepared for. Alphabet fell more than 4% in after-hours trading following its Q2 2026 earnings report. Tesla saw shares slide nearly 3% on the news and has continued to face market pressure since.
The numbers that spooked the market #
Alphabet revised its full-year capital expenditure guidance upward to a range of $195 to $205 billion, compared to a prior estimate of $180 to $190 billion. That is an incremental commitment of roughly $15 billion on top of what was already a historic spending level.
Alphabet’s property and equipment spend reached $44.9 billion in Q2 2026 alone. The company’s cloud revenue growth came in strong, surpassing 80% year-over-year. Alphabet’s free cash flow has turned negative as a result of this capital expenditure level.
Tesla raised its 2026 capex target to over $25 billion back in April, nearly triple its 2025 spending of $8.53 billion. The money is earmarked for AI infrastructure, robotaxi development, and the Optimus robotics program. As of mid-2026, Tesla had spent approximately $2.5 billion of that $25 billion target. The company anticipates negative free cash flow for the remainder of the year.
Why investors are nervous, not just cautious #
Alphabet is also reportedly pursuing approximately $80 to $85 billion in equity raises in 2026 to fund its AI infrastructure buildout. Equity raises dilute ownership and signal that internal cash generation is not sufficient to cover the pace of investment the company has committed to.
What this means for tech investors going forward #
Alphabet and Tesla are not outliers. The combined spending on AI infrastructure across major technology companies could reach hundreds of billions of dollars in 2026.
Alphabet’s cloud segment growing at over 80% year-over-year suggests that demand is real and customers are spending. Tesla’s AI bets, specifically robotaxis and Optimus, are in categories that do not yet have established revenue models at scale. As of mid-2026, Tesla had spent only $2.5 billion of its $25 billion capex target, with the bulk of that commitment still ahead of it.
