2026 Top 100 US Commercial Contractors Released: Turner Construction Tops for Six Consecutive Years
Engineering News-Record's 2026 Top 400 US Commercial Contractors list was released on Wednesday. Turner Construction of New York topped the list for the sixth consecutive year with $28.3 billion in revenue; Bechtel of Reston, Virginia, continued to rank second; and STO Building Group of New York jumped from sixth last year to third, pushing Kiewit of Omaha, Nebraska, down to fourth. The list shows that the AI data center construction boom has driven significant revenue growth among top firms, but the industry also faces multiple pressures including tariffs, the Iran situation, and skilled labor shortages.

Quick Overview
- According to the 2026 Top 400 U.S. Commercial Contractors list released by Engineering News-Record on Wednesday, New York City-based Turner Construction ranked first among U.S. contractors by revenue for the sixth consecutive year. The list is ranked based on companies' self-reported 2025 revenue.
- Reston, Virginia-based Bechtel again took second place. However, New York City-based STO Building Group jumped from sixth place last year to third, pushing Omaha, Nebraska-based Kiewit down to fourth.
- Similar to 2025, the top three contractors all saw year-over-year revenue growth.

Deep Insights
Mortenson continued its impressive growth momentum. After rising five spots to No. 22 in 2025, the company jumped another 12 places in the 2026 list, breaking into the top 10. The Minneapolis-based company's 2025 revenue reached $10.8 billion, a significant increase from $6.7 billion in 2024.
A merger of two well-known firms also drove one company's rise in the rankings. In 2024, Flatiron and Dragados, previously ranked No. 51 and No. 37 respectively, merged to form Atlanta-based FlatironDragados. The infrastructure giant posted 2025 revenue of $7 billion, ranking No. 25 on the list.
Several companies in the top 10, such as Bechtel, HITT Contracting, and Mortenson, also appeared on Forbes' recent list of America's 100 Largest Family-Owned Companies, which also included other construction-related firms.
Other companies in the top 50 that rose five or more spots in the rankings include:
- Boston-based Suffolk, rising from No. 28 to No. 23
- Dallas-based Balfour Beatty US, rising from No. 32 to No. 27
- Los Angeles-based Tutor Perini, rising from No. 33 to No. 28
- Lexington, Kentucky-based Gray, rising from No. 36 to No. 30
- Minneapolis-based Ryan Cos., rising from No. 43 to No. 33

Meanwhile, companies in the top 50 that fell five or more spots year-over-year include:

- Dallas-based Austin Industries, falling from No. 31 to No. 41
The list comes amid a market of stark contrasts: data center construction on one side, and everything else on the other. On one hand, the AI boom has builders overwhelmed—Turner Construction, for example, set a 2025 revenue record thanks to data center work. In fact, data center construction in March almost single-handedly supported planning activity, mainly benefiting contractors involved in these projects. However, for builders outside the data center sector, business has been relatively subdued.
Other issues are equally challenging. Tariffs, the Iran situation, commodity prices, and the long-standing skilled labor shortage are forcing contractors to contend with multiple obstacles simultaneously. For example, although publicly traded builders downplay the impact of the Iran war, according to the Associated Builders and Contractors, input price increases over the past four months have exceeded the cumulative increases of the past three years.
