Definitions

To help readers understand the content better, the following terms and glossaries have been provided.

Capital Expenditures: Alphabet makes investments in land, buildings, and servers and network equipment through purchases of property and equipment and lease arrangements to provide capacity for the growth of the company’s services and products.

Capital Expenditures

Alphabet’s capital investments in property and equipment consist primarily of the following major categories:

• technical infrastructure, which consists of our investments in servers and network equipment, data center land, and building construction and improvements; and

• office facilities, ground-up development projects, and building improvements.

Assets not yet in service are those that are not ready for their intended use, including assets in the process of construction or assembly, and consist primarily of technical infrastructure. The time frame from date of purchase to placement in service of these assets may extend from months to years.

For example, data center construction projects are generally multi-year projects with multiple phases, where Alphabet acquires land and buildings, construct buildings, and secure and install servers and network equipment.

During the years ended December 31, 2024 and 2025, Alphabet spent $52.5 billion and $91.4 billion on capital expenditures, respectively. In 2026, Alphabet expect to significantly increase, relative to 2025, its investment in technical infrastructure, including servers and network equipment, and data centers.

Depreciation of property and equipment commences when such assets are ready for their intended use. For the years ended December 31, 2024 and 2025, depreciation on property and equipment was $15.3 billion and $21.1 billion, respectively.

Insight & Summary of Alphabet’s Capital Expenditure

The following analysis consolidates the trends observed across Alphabet’s capital expenditure for the 2016–2025 period.

• Alphabet’s capital expenditures grew from $10.2B in 2016 to $91.4B in 2025 — nearly a 9x increase over nine years — with the most dramatic acceleration occurring in 2024 and 2025, where capex surged 62.9% and 74.1% respectively. These two years alone added $59.2B in incremental annual capex relative to the 2023 baseline of $32.3B, representing an investment step-change of a magnitude not seen in the company’s prior history and reflecting the strategic imperative to build AI infrastructure at scale ahead of enterprise demand.

• The absolute capex figure of $91.4B in 2025 is extraordinary in the context of Alphabet’s own trajectory — surpassing the cumulative capex of the entire 2016–2021 period combined — and underscores the conviction with which management is committing capital to data centers, custom AI accelerators, and network infrastructure as the foundational layer of its next decade of growth.

• Operating cash flow has grown in parallel with capex throughout most of the period, expanding from $36.0B in 2016 to $164.7B in 2025 — a 4.6x increase that reflects the compounding cash generation of Google’s advertising and, more recently, Cloud businesses. However, the pace of capex growth has materially outstripped operating cash flow growth in 2024 and 2025, causing the capex-to-operating-cash-flow ratio to surge from a trough of 26.9% in 2021 to 55.5% in 2025 — the highest level in the period and a level that signals a deliberate and sustained prioritization of investment over near-term free cash flow maximization.

• The ratio had previously been most elevated in 2018 at 52.4%, coinciding with the last major infrastructure buildout cycle, before moderating through 2021 as operating cash flow scaled faster than investment needs. The current elevation above that prior peak confirms that the AI infrastructure cycle represents a structurally larger and more sustained investment commitment than any prior capex cycle in Alphabet’s history.

• The capex growth pattern across the period reflects three distinct phases. The first, from 2016 to 2018, saw aggressive investment with 29% and 91% growth as Google scaled its data center and network infrastructure to support search and YouTube growth — the 91% spike in 2018 being the largest single-year growth rate until recently.

• The second phase, from 2019 to 2023, was characterized by moderation and discipline — capex growth was low-to-mid single digits in most years, the ratio to operating cash flow declined, and free cash flow expanded meaningfully as the business harvested returns from prior investment cycles. The third and current phase, beginning in 2024, represents a deliberate and emphatic re-acceleration driven by AI compute demand — with the $91.4B deployed in 2025 serving as both a competitive necessity and a strategic signal to the market that Alphabet intends to lead rather than follow in the AI infrastructure arms race.

• Whether the returns on this investment cycle justify its scale will be the defining capital allocation question for Alphabet’s next several years, and the trajectory of Google Cloud’s revenue and margin improvement will be the primary yardstick against which this spending will ultimately be judged.

The table below combines all Alphabet’s capital expenditure metrics into a single view for the latest three fiscal years.
