Should You Buy Alphabet Stock For The Chips It Now Sells?
Alphabet (GOOGL) stock has drifted, returning negative 6.8% over the past three months while the S&P 500 returned 3.6%. The strongest evidence for upside from here is not in the advertising business that pays the bills. It sits in a revenue line the company only began recognizing in the second quarter of 2026: TPU system sales, shipped into customers’ own data centers.
Alphabet Now Ships TPUs Into Other Companies’ Data Centers
The TPU is the chip Alphabet built for itself, and much of its cloud serving still runs on it. In the second quarter of 2026 the company delivered TPU systems to customer data centers for the first time and started booking revenue on those sales. Management frames that as an expansion of its total addressable market, and does not break out what the chips earn. Only a small portion of those agreements converts in 2026, with the vast majority of the revenue expected in 2027.
TPU system sales sit inside the cloud backlog, though the vast majority of that total is GCP agreements. Google Cloud’s backlog reached $462 billion at the end of the first quarter of 2026 and $514 billion at the end of the second, an increase of more than $50 billion in a single quarter. Alphabet says it remains supply constrained, and cloud revenue grew 82% year over year to $24.8 billion in the second quarter even so—growth management noted was driven primarily by GCP and accelerated meaningfully even excluding TPU sales.
How Much Of That $514 Billion Actually Lands In Revenue
Management expects just over half of that backlog to be recognized as revenue within 24 months of the second quarter of 2026. That is roughly $260 billion of contracted cloud revenue spread across two years, set against trailing-twelve-month revenue of $445.9 billion for the whole company.
At roughly $130 billion annually, that contracted run rate more than covers the current cloud business and underpins its ongoing expansion, sustaining top-line growth rather than transforming the company’s trajectory overnight. The honest bull case is a company compounding faster for longer rather than a business about to be re-rated.
The conversion already shows in the segment. Cloud operating income more than tripled year over year in the second quarter of 2026, and the segment’s operating margin moved from 20.7% a year earlier to 35.6%. Management attributes that to operating discipline and leverage on a growing top line.
Alphabet Plans To Rent Capacity To Keep That Growth Coming
There is a bill attached. Alphabet plans to expand its use of third-party capacity in the third quarter of 2026 as a bridge while it builds more of its own, and management says that will create modest margin pressure in the near term. Full-year 2026 capital spending guidance moved up to a range of $195 billion to $205 billion. Free cash flow was negative $5.9 billion in the second quarter of 2026, against $53.3 billion for the trailing twelve months, and management expects it to stay under pressure.
A stock does not need a transformation to move. A critical test for whether this hardware expansion maintains capital efficiency will be Google Cloud’s operating margin over the second half of 2026: management has guided it lower on rented capacity and integration costs for its Wiz acquisition, making margin preservation a central metric to watch.
