Largest trucking companies in the US: ranked by revenue and by fleet size

This list is for anyone who sells to trucking companies (fuel, tires, trucks and trailers, telematics, insurance, software, staffing) and for shippers and job seekers sizing up carriers. It ranks US-headquartered public freight companies by the revenue in their latest annual report, then ranks fleets by the power units each carrier reports to the Federal Motor Carrier Safety Administration (FMCSA), which brings in the private carriers that file no 10-K. For the full register of two million carriers and how to download it, see the list of trucking companies.

The largest trucking companies by revenue

Revenue is total revenue as reported in each company's latest 10-K. Employees are from the same filing; Werner (drivers, maintenance, office and logistics staff) and Covenant (about 2,900 drivers and 1,800 others) are our sums of the filing's figures, and Heartland's is its count at the end of January 2026.

Three notes on the table. FedEx's fiscal 2026 revenue still includes FedEx Freight, which FedEx spun off as a separate listed company on June 1, 2026; from fiscal 2027 the two report separately. TFI International, which bought UPS Ground Freight (now TForce Freight) in 2021, reported $7.88 billion of 2025 revenue but is headquartered in Saint-Laurent, Quebec. Hub Group, the intermodal and logistics company in Oak Brook, Illinois, is left out because it has no reliable revenue figure: on 12 May 2026 it said its audited 2023 and 2024 statements were materially misstated and shouldn't be relied on, it still hasn't filed its 2025 annual report, and on 16 September 2026 Nasdaq issued a delisting determination, which the company said it would appeal.

The largest fleets in the federal register

Every interstate carrier reports its power units (trucks and tractors) and drivers to FMCSA on Form MCS-150. Ranked by power units, these are the largest carriers with for-hire authority:

FMCSA Company Census File, data as of October 29, 2026. Active interstate carriers with for-hire authority, excluding passenger carriers. We kept records updated since October 2024 whose reported drivers and annual mileage are consistent with their fleet size, which drops dozens of records with obviously mistyped fleets (some claim 100,000 trucks and two drivers). Names in brackets are the registered trade names.

Read this table with two cautions. First, it counts DOT numbers, not companies. Knight-Swift's 10-K treats Swift, Knight and US Xpress as its subsidiaries; their records add up to 21,093 power units (12,940, 3,200 and 4,953), close to the 21,428 tractors its truckload segment averaged in 2025. Second, some large carriers drop out because their records are stale: Werner's last update was July 2024, and ABF Freight's and Central Transport's were also before October 2024. The table also includes private fleets of retailers, distributors and equipment companies that hold for-hire authority, such as Walmart's, Tyson's and US Foods'. Those are real buyers of trucks, fuel and fleet software even though they don't sell trucking.

The trucking industry by segment

County Business Patterns counts trucking establishments with paid employees (NAICS 484). UPS and FedEx Express are classified as couriers, so they aren't in these figures.

County Business Patterns 2023, establishment counts by employment size.

Of the 170,286 trucking establishments, 123,520 (72.5%) have fewer than five employees. LTL is the most concentrated segment: it has a sixth as many establishments as truckload but almost half the employees, because LTL runs on big terminal networks.

How these lists are built

• Revenue is each company's total revenue as reported in its 10-K, for its latest fiscal year. Brokers (C.H. Robinson, RXO) and asset-light carriers (Landstar) are included because they move truckloads and compete for the same shippers; their revenue includes what they pay other carriers.
• Fleet is self-reported power units on each carrier's MCS-150, which federal rules require carriers to update every 24 months. It includes straight trucks and delivery vans, which is why the parcel companies dwarf everyone else.
• Left out: revenue for carriers that file no annual report with the SEC (Estes, R+L Carriers and Prime among them), and companies headquartered outside the US. Transport Topics and FreightWaves publish their own rankings; we didn't use them.

Where the buying happens at a trucking company

General guidance, informed by the filings. A carrier's costs are drivers, equipment, fuel, insurance and terminals, and each has an owner.

• Drivers and safety. Drivers are most of the workforce: 10,320 of Old Dominion's 20,591 full-time employees, and about 51% of Saia's. Safety, recruiting and driver retention leaders buy training, cameras, background checks and recruiting services.
• Equipment and maintenance. The vice president of maintenance or equipment buys tractors, trailers, tires and parts on replacement cycles. Old Dominion keeps new tractors in linehaul for about three to five years before moving them to pickup and delivery.
• Operations and network. LTL carriers run terminals (Saia had 213 at the end of 2025), so dock, yard and routing tools sell to the operations team and terminal managers.
• Asset-light carriers buy differently. Landstar works through about 960 independent commission sales agents and over 70,000 third-party capacity providers, so a seller there is often selling to the agents and contractors, not the head office.

Worked example: a camera vendor targets the next tier of fleets

Illustrative example. The vendor and its pricing are fictional; the fleet sizes come from FMCSA's Company Census File as of October 29, 2026.

The seller: Lookout (lookout.example) sells driver-facing safety cameras at an illustrative $35 per power unit per month. The largest fleets run long tenders, so Lookout targets for-hire fleets with 3,000 to 5,300 power units.

The list. Fourteen records in the register fit: Crete Carrier (5,257), US Xpress (4,953), Ryder Transportation Solutions (4,471), CRST Expedited (4,362), AAA Cooper Transportation (4,339), TForce Freight (4,155), Pitt Ohio Express (3,889), CR England (3,807), Marten Transport (3,794), Western Express (3,332), Heartland Express of Iowa (3,320), NFI Interactive Logistics (3,294), Knight Transportation (3,200) and Southeastern Freight Lines (3,177).

The arithmetic. Together they report 55,350 power units. At $35 a month that is $23.2 million a year if every unit were covered (55,350 × $35 × 12 = $23,247,000). Winning an illustrative three fleets of about 4,000 units each is about $5.0 million a year.

The plan.

1. Merge records that belong to one company. US Xpress and Knight Transportation are both Knight-Swift subsidiaries; treat them as one account with one buying process.
2. Find the safety leader at each fleet, plus the operations or maintenance leader who will manage installation.
3. Open with the carrier's own safety record, from FMCSA's public inspection and crash data, not a generic pitch.

Finding the safety and maintenance leaders at fourteen carriers, and what's changed at each, is the slow part. Bebop researches each account in a list like this and drafts the first message.
