The Depreciation Bridge Alphabet's Preview Asked For Arrived Negative
The July 22 preview asked whether capex would keep outrunning cash. The July 23 print didn't just answer that — free cash flow went negative for the first time since the 2004 IPO.
What the preview was waiting on
The preview written the day before this report closed on an open question: Alphabet’s capex had outrun its free cash flow by $18.1 billion in fiscal 2025, and the company had not yet disclosed a current depreciation figure to show how much of that build had reached its income statement. The preview called that gap “the depreciation bridge” and said the street could see the cash leaving without yet seeing the earnings drag arriving.
The July 23 report closed the gap with a number sharper than the question anticipated. Alphabet reported second-quarter revenue of $119.8 billion, up 24% year over year and above the $116.9 billion estimate — Google Cloud revenue rose 82% to $24.8 billion, and Google Services revenue rose 15% to $94.5 billion, with YouTube ad revenue up 13% to $11.06 billion. Every top-line number beat. Alphabet’s stock fell more than 7% anyway.
The first negative quarter since the IPO
The reason sat below the revenue line. Google’s free cash flow came in at negative $5.9 billion for the quarter — the company’s first cash burn since it went public in August 2004, a run of 22 years of positive free cash flow ending in a single print. The preview’s own FY2025 numbers put Alphabet’s free-cash-flow margin at 18.2%, already down from 20.8% a year earlier. Q2 2026 didn’t extend that decline. It crossed zero.
Capex explains why. Google’s quarterly capex grew 100% year over year to $44.92 billion, and the company raised its full-year 2026 guidance to $195–205 billion, up from the $190 billion ceiling it had given in April — a second upward revision inside one year, not a one-time step. The preview’s FY2025 capex-to-revenue ratio was 22.7%, already 7.7 points above FY2024’s 15.0%. A single quarter at $44.92 billion, annualized, runs well past even the raised full-year guidance’s low end — the company is spending faster than its own most recent forecast assumed, which is presumably why the forecast moved again. Scaled against the preview’s own FY2025 baseline, one quarter of 2026 capex already equals roughly 49% of the entire prior year’s $91.4 billion — a pace that, held for four quarters, would nearly double annual spending rather than land inside the $195–205 billion range the company just gave.
What the spending bought, on paper
The counterweight the company offered the same day was demand it hasn’t yet turned into revenue: Google’s cloud unit disclosed a $514 billion backlog of contracted work not yet recognized, up from roughly $460 billion in the first quarter — a $54 billion increase in three months, and a backlog now more than 20 times the quarter’s entire cloud revenue of $24.8 billion. That is the bull case in one figure: demand is outrunning the company’s ability to book it, not falling short of the spending meant to serve it. It is also, on the record alone, unverifiable as anything more than a contracted-but-undelivered claim — a backlog is a promise to bill, not cash, and the free-cash-flow line that same day is what actually happened.
The preview asked whether Alphabet’s depreciation growth would show how much of the AI build had reached the income statement, or whether the capex growth would show how much more remained in the pipeline. The July 23 print answered with the second: $44.92 billion spent in one quarter, guidance raised again, and free cash flow negative for the first time in the company’s public history. Whether the $514 billion backlog converts fast enough to reverse that is the question this print opened, not the one it closed.
