Alphabet and Tesla Shares Drop as Surging AI Capital Expenditures Hit Cash Flow

Alphabet and Tesla shares fell in after-hours trading Wednesday after both companies reported negative free cash flow and warned of escalating capital expenditures. Despite delivering better-than-expected revenue, Tesla stock slid 4 percent and Alphabet dropped more than 3 percent.

The immediate market reaction highlights growing investor scrutiny over the return on investment for artificial intelligence infrastructure. This dynamic sets a tense backdrop for other megacap technology firms, including Meta, Microsoft, Amazon, and Apple, which are scheduled to report results next week.

Alphabet forecast full-year capital expenditures of $195 billion to $205 billion, raising its previous guidance of $180 billion to $190 billion. Chief Financial Officer Anat Ashkenazi noted that free cash flow sank to negative $5.9 billion in the second quarter, down from almost $25 billion a year earlier.

Most of the company’s $44.9 billion in second-quarter capital spending targeted technical infrastructure to support AI buildout. To meet feverish computing demand, Google also plans to rely on third-party cloud providers, building on a recent compute deal with SpaceX.

Mizuho analysts described the spending increase as broadly anticipated, pointing to an 82 percent year-over-year surge in cloud revenue and accelerated usage of the Gemini model. The firm expressed surprise at the after-hours selloff and maintained a buy recommendation, expecting the stock to recover.

Tesla reiterated its expectation for more than $25 billion in capital expenditures this year, representing roughly 200 percent year-over-year growth. Second-quarter spending jumped 142 percent to $5.79 billion, pushing free cash flow to a negative $1.1 billion deficit, down from $1.44 billion in the first quarter of 2026 and $146 million a year earlier.

Chief Executive Elon Musk defended the aggressive outlay, which funds self-driving technology, robotics, and a new AI chip-manufacturing plant in Texas. "It's ok to be a little less capital efficient if we get things done sooner," Musk said, comparing the current industrial scale-up to Henry Ford’s production of the Model T.

Bullish observers argue the short-term cash burn is a necessary phase for long-term dominance. Keith Fitz-Gerald of the Fitz-Gerald Group noted that profitability is being sacrificed for infrastructure, a pattern previously seen at Amazon and Netflix that he expects to pay off within 12 to 36 months.

The spending surge occurs as the tech-heavy Nasdaq has dropped about 5 percent since reaching a record in early June. Concerns are mounting that cheaper open-source models from China and increasing corporate frugality could undermine the future profitability of historic AI infrastructure investments.
