2026 FleetOwner 500: Private list

Consolidation and control drive the U.S.’s 500 largest private fleets to surpass the 1 million vehicle milestone.

Key takeaways

  • Private fleets surpassed 1M power units, signaling growing in-house capacity across industries.
  • M&A activity is reshaping rankings as companies absorb logistics to control supply chains.
  • Food, retail, and construction fleets dominate, driving most private fleet vehicle growth.

Commercial transportation, the engine that drives the U.S. economy, is powering more of the world’s most recognizable brands. You might wonder where they would be today without their ability to move their goods, deploy their equipment, and provide their services.

For the first time on record, the FleetOwner 500: Private, our annual ranking of the largest non-trucking company fleets, surpassed 1 million power units. The 1,004,443 commercial vehicles employed by the FO500 fleets represent the lifeblood of industries ranging from wholesale retail and food products to public utilities, manufacturing, construction, sanitation, and more.

While the middle of the 2026 rankings saw wild shifts this year—driven by M&A consolidation as retail giants absorbed regional logistics operations to control their own capacity—the private fleet heavyweights remained largely the same, despite some minor ranking shuffles. 

With more than 29,000 power units, sanitation giant WM maintains the No. 1 overall spot. PepsiCo, operating a classic mixed fleet that includes Frito-Lay, retains the No. 2 ranking. Sanitation fleet Republic Services (No. 3), construction fleet Quanta Services (No. 4), and national utility provider AT&T (No. 5) round out the top five. Just these top five fleets alone account for more than 11% of the entire FO500's capacity.

Beneath the top 10, however, you can find how the consolidation trends are changing corporate supply chains and services. Home Depot, for example, jumped 66 spots in 2026 to No. 17 overall, thanks to its acquisition of Gypsum Management & Supply. Quikrete Cos. (up 90 spots to No. 47) saw the largest leap among the 50 largest private fleets, thanks to its taking over Summit Materials. 

Further down, companies such as Installed Building Products skyrocketed more than 300 spots into the Top 100. In comparison, General Motors vaulted 249 spots to No. 67 after a U.S. Department of Transportation (USDOT) administrative update fully revealed the massive scale of the automaker's internal testing and parts logistics networks.

The 2026 FleetOwner 500: Private welcomes 45 new or returning companies to the list, helping push it over the 1 million power-unit mark.

By sheer volume, three operational types dominate today's private fleet landscape:

  • Food products: 73 fleets accounting for an industry-leading 160,390 power units (anchored by PepsiCo at No. 2 and Performance Food Group at No. 15).
  • Retail/Wholesale: 86 fleets making up 136,587 power units (led by Amazon at No. 6 and Walmart at No. 8).
  • Construction: 71 fleets managing 134,444 power units (driven by Quanta Services at No. 4 and MasTec at No. 7).

Below, you will find the complete ranking of these 500-plus private fleets, categorized by operational type, vehicle counts, and geographical footprint.

Methodology

Since 2023, FleetOwner has partnered with the analysts at ProsperFleet to build the FO500, which primarily relies on the most recent information companies filed on Form MCS-150 with the Federal Motor Carrier Safety Administration (FMCSA) to count power units, trailers, and drivers. This ensures a consistent playing field for all carriers operating in the U.S.

Analysts at ProsperFleet also use the companies' websites, press releases, and hierarchy from their business databases to roll USDOT operating entities into a single parent company. ProsperFleet then cleanses, validates, standardizes, and enhances company and contact information to create a complete fleet view.

For companies with subsidiaries and divisions that have USDOT numbers, the subsidiaries' vehicle counts are included in the parent company's total on the FO500.
