Data center construction spending tops airports, ports, transit combined

US data center construction spending has crossed a milestone that puts the AI buildout on a different scale than most traders realize. Spending on data centers in the US has surpassed spending for public transportation infrastructure, with construction outlays clearing $50 billion, per a Bloomberg analysis flagged by Yahoo Finance.

For context, that figure now beats what the country spends on airports, marine terminals, and mass transit systems combined.

The numbers

Data centers now account for 2.3% of all US construction spending, according to the report, which provides annualized rates that are not adjusted for inflation.

Private-sector outlays for data centers also outpaced public spending on transportation-related structures — a category that includes airport facilities, marine terminals and mass transit — for the first time.

By January 2026, annualized spending on data center construction climbed to approximately $46.9 billion, surpassing traditional office construction, which totaled about $43.7 billion. The shift marks the first time data centers have overtaken office buildings in total construction spending. The transit milestone followed a few months later.

Why this matters for the tape

The rise of data centers is not just notable—it is critical to the stability of the broader construction market. According to industry data, without ongoing investment in data center projects, nonresidential building spending would decline by an estimated 3.8% in 2026.

In other words, the AI capex cycle is now structurally important to US nonresidential construction. A pause from the hyperscalers would not just be a tech story, it would be a macro story.

Power and supply are the bottleneck

Research from CBRE found that data center capacity under construction actually fell from 6.35 megawatts in 2024 to 5.99 megawatts by the end of 2025 — but the bottleneck doesn’t appear to be demand, but more mundane supply issues, with deal implementation at the local level, including slow permitting and constrained supply chains, seemingly causing the slowdown.

Louisiana currently leads all states in data center spending over the past twelve months, establishing a new record for single-state investment. This leadership position stems primarily from the $10 billion Meta data center construction project in Richland County.

Data centers are energy intensive, and many require large amounts of electricity and water for cooling. As more facilities come online, utilities are being pushed to expand generation and transmission capacity to keep up. Some energy analysts warn that if growth outpaces planning, it could strain power grids, raise electricity costs, or slow progress toward cleaner energy goals.

Options market and stocks to watch

Watch the names plugged directly into the buildout:

• NVDA: still the core GPU supplier for every hyperscaler order book.
• VRT: Vertiv supplies power and thermal management gear that the spending boom requires.
• ETN: Eaton sits on the electrical infrastructure side, watch for flow tied to grid capex commentary.
• EQIX and DLR: the pure-play data center REITs, watch for sensitivity to permitting and power headlines.
• META: anchor tenant behind the largest single-state build, per ConstructConnect data.
