We all know the US Data Center construction market is booming…but the 2026 Engineering News-Record rankings highlight the sheer scale of this growth!

The Top #10 Contractors generated $60.3 billion in data center revenue, up 76.3% in one year…

1. HITT Contracting Inc.
2. Turner Construction Company
3. Holder Construction
4. DPR Construction
5. Mortenson
6. Clayco
7. The Whiting-Turner Contracting Company
8. MasTec
9. STO Building Group
10. Fortis Construction, Inc.

However, their combined market share has fallen, meaning the market is expanding beyond the established leaders, with an increasing share of data center work being captured by contractors outside the Top #10.
