Alphabet's Cloud Backlog Hits $561 Billion and Cloud Is 24% of Revenue, but Stock Ended Thursday 12.6% Lower

Since Alphabet's Oct. 28 third-quarter report, the stock has dropped 12.64% to $283.82 at Thursday's close. The filing detail shows a company whose center of gravity is shifting fast toward Cloud, and whose spending is shifting faster.

Cloud is now a quarter of the company

Google Cloud revenue hit $30.7 billion, up 103%. That is 24.1% of Alphabet's $127.6 billion in total revenue, up from 14.8% a year earlier. Growth has accelerated from 63% in Q1 to 82% in Q2 to 103% now.

Cloud operating income rose to $11.12 billion from $3.59 billion. The margin widened to 36.2% from 23.7%.

The contracted backlog reached $561 billion, up from $514 billion in Q2 and $460 billion in Q1. About 55% of it is expected to convert to revenue within 24 months, up from 50% last quarter. That works out to roughly $308 billion over eight quarters.

Cloud CEO Thomas Kurian, in his first public earnings-call remarks, said Alphabet is "seeing extraordinary demand and strong growth from both AI labs, capital markets, financial service institutions, and enterprises."

Everything else missed

Jefferies analyst Brent Thill put it bluntly on CNBC: "The cloud business was the only business that beat at 103% growth. The Street wanted 100%, so it didn't beat by much, and it missed some of the high-end targets. Everything else missed."

The numbers back him up. Operating income of $40.58 billion fell short of the $43.19 billion FactSet forecast. Adjusted EPS of $2.67 missed the $3.02 estimate. Search and other revenue grew 12% to $63.35 billion, and YouTube advertising rose 9% to $11.2 billion.

Capex was actually lower than expected: $51.36 billion against the $55.09 billion analysts projected. Free cash flow still came in at negative $9.07 billion, against an expected positive $2.70 billion.

Alphabet held its 2026 capex range at $195 billion to $205 billion. Ashkenazi told analysts: "We continue to expect our capex to increase significantly in 2027, and will provide further details on our Q4 call." CNBC reported that annual capex is expected to exceed $300 billion in 2027. Alphabet has given no figure.

The SpaceX number has more than one version

Alphabet said other income and expense was negative $8.2 billion, driven primarily by an unrealized loss on its SpaceX stake. Separately, it booked an $8.66 billion net loss on equity securities across its portfolio. That compares with a $99.03 billion gain in Q2 from stakes including SpaceX and Anthropic.

Invezz estimated an $11 billion pre-tax hit. Its math: roughly 550 million SpaceX shares falling from about $171 to $151 during the quarter. That is an outside calculation. It is higher than the loss Alphabet reported, and the filing does not reconcile the two.

Alphabet also made a $5.2 billion cash payment for an EU antitrust fine, according to Motley Fool columnist Anders Bylund, who argued it amplified the earnings shortfall.

The case that the selloff overshot

Not everyone reads the quarter as a warning. Bylund wrote that "the miss looks more like an accounting paper-cut than a broken business model," pointing to Cloud's growth and the largest search query growth in five years. A separate Motley Fool analysis noted that operating income, which excludes investment gains and losses, rose 30%. It called that a better gauge of how the business performed. It also said the $561 billion backlog equals about four and a half years of Cloud revenue at its current pace.

The cautious reading focuses on cash. Search growth slowed to 12% from about 17% in Q2. Management blamed currency moves, softer retail ad spending in Asia, and lower monetization in AI Mode. Long-term debt stands at $125.1 billion, up from $21.6 billion a year ago.

Bylund noted that rising depreciation and amortization from data center spending is beginning to hit the income statement. He put the trailing P/E at 15.0 and the forward multiple near 19.0.

Where the stock stands

As of 11:50 a.m. ET Thursday, Bylund calculated Alphabet had lost about $410 billion in market value. At the close, the market cap sat near $3.47 trillion. The Class A shares ended well below the $322.22 close from before the report. Thursday's session range was $280.36 to $288.33, and the 52-week range runs from $270.70 to $408.61.

Chief executive Sundar Pichai pointed to a "half-trillion dollar revenue run rate." Chief business officer Philipp Schindler said advertising in AI Mode will roll out to international markets.

The next hard data point is the Q4 call. That is where Alphabet has said it will lay out its 2027 capex plan. Investors will find out then whether the spending ceiling rises well past this year's $195 billion to $205 billion range, and whether Cloud's backlog is converting fast enough to cover it.
