The 2025 FleetOwner 500: Private list ranks the most prominent private carriers in the U.S. by total registered power units. Released in April, the FO500 saw many ranking shifts after a busy 2024 of carrier acquisitions, mergers, consolidations, and expansions.
In addition to ranking the largest private fleet operations overall, FleetOwner breaks down these companies into categories based on equipment, cargo types, and industry segments. This media gallery focuses on the fleets with the most tractors.
