For the first time in over two decades as a public company, Alphabet just burned more cash than it generated. Google’s parent reported negative $5.9 billion in free cash flow for Q2 2026, a milestone that would have been unthinkable just a few years ago for one of the most reliably profitable businesses on earth.

The culprit is straightforward: capital expenditures hit $44.9 billion in a single quarter, doubling year-over-year. Alphabet spent nearly $45 billion in three months building out AI infrastructure.

The numbers behind the AI arms race

Operating cash flow clocked in at $39.1 billion for the quarter. But when you’re spending $44.9 billion on data centers, chips, and the physical backbone of AI, even $39 billion in operating cash doesn’t cover the bill. The $5.9 billion gap represents the first time Alphabet has ever posted negative free cash flow since going public in 2004.

Alphabet raised its full-year 2026 capex guidance to as high as $205 billion, up from a previous estimate of $180-190 billion. CFO Anat Ashkenazi acknowledged that free cash flow is expected to remain under pressure as AI investments continue to ramp.
