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 transportation fleets.

The shortest category for the FO500, there are only four private fleets on this list. Last year, there were five, but Metro-North Railroad fell off the list. The four remaining fleets experienced varying growth this past year, but their positions on this list remain the same compared to 2024.
