The AI boom is usually told as a story about chips, software, and electricity. DAT iQ principal analyst Dean Croke makes the case that it is just as much a trucking story — and his latest flatbed report puts a number on it: "each gigawatt of new data center capacity translates to roughly 100,000 truckloads of concrete, structural steel, transformers, switchgear, and generators."
The scale is easy to underestimate. The U.S. has built out roughly 20 gigawatts of new data center capacity since the AI boom took off in 2023 — about 2 million truckloads already moved. The pipeline announced for 2026–2027 is another 50 gigawatts, which would translate to roughly 5 million additional truckloads over two years. That is a major new freight market layered on top of everything the network already carries.
The Freight Behind the Headlines
Every phase of a data center build moves on trucks: concrete and rebar first, then structural steel, then the electrical backbone — transformers, switchgear, backup generators — and finally the precision cooling equipment that keeps the servers running. Most of it is flatbed and heavy-haul work, and it concentrates in specific corridors around active construction sites rather than spreading evenly across the country.
The demand is visible in the rate data. In the week covered by the report, the national average flatbed spot rate eased 5 cents to $2.95 per mile (linehaul, excluding fuel surcharges) — but that is still 44% higher than a year ago, an 89-cent-per-mile gain, and 32% above the five-year average excluding the pandemic spike. Flatbed load posts are up 48% year over year, and even after a 15% weekly pullback, the load-to-truck ratio stands at 44 loads for every posted truck. In DAT's ten-state bellwether corridor, which handles roughly 55% of national flatbed volume, spot rates average $3.50 per mile.
Announced Isn't the Same as Breaking Ground
Croke pairs the opportunity with a discipline check. Only about a third of the 2026 project pipeline is currently under active construction, and industry estimates suggest close to half of announced projects could slip or be canceled. Data center builds run 18 to 24 months, transformers and other power equipment carry multi-year waitlists, and press-release calendars rarely match the concrete pours — so the freight arrives in waves, not a steady stream.
"The gap between what's announced and what's actually breaking ground is where the real freight opportunity — and risk — lives," Croke wrote in the report.
What This Means for Fleet Owners
For carriers weighing where to put their next equipment dollar, the data center build-out is one of the clearest demand signals in the market — as long as it is read carefully:
- This is durable, multi-year demand. Even if half the announced pipeline slips, millions of incremental truckloads still hit the network on top of normal construction freight. That supports flatbed utilization measured in years, not quarters.
- Flatbed is the entry point. With spot rates 44% above last year and load posts still climbing, flatbed and step-deck capacity added now goes to work immediately — and specialized heavy-haul equipment positions a fleet for the highest-value moves in the cycle.
- Follow construction starts, not press releases. The fleets that win this freight are positioned where projects are actually breaking ground. The risk isn't demand disappearing — it's committing equipment against a project that slips a year.
We've seen versions of this before: when a structural demand story meets a tight equipment market, the carriers who benefit most are the ones whose capacity plans were already in motion. With trailer and truck availability tightening across the board, the operators best positioned for the next wave of data center freight are the ones for whom financing — not equipment — is already arranged when the next corridor lights up.
