Top 10 Tank Fleets Hold Steady, Depot Connect Jumps 100 Spots

Which tank fleets ranked highest in 2026?

The top five U.S. for-hire tank fleets held their positions from 2025 to 2026, according to the FleetOwner 500 rankings released June 4. The list ranks the largest motor carrier and commercial fleet operations in the country by equipment and cargo segment. The bottom half of the top 10 saw movement, with Depot Connect rising more than 100 spots in the overall for-hire rankings to land at No. 160.

Tank fleets haul liquid and dry bulk cargo, a segment that requires specialized equipment, routing, and driver training distinct from dry van or flatbed operations. The FleetOwner 500 breaks carriers into categories by equipment type and primary cargo, isolating bulk haulers from general freight, refrigerated, and LTL carriers.

What changed in the tank fleet rankings?

The top five spots remained identical to 2025. FleetOwner did not publish the names of those five carriers in the June 4 release, but the stability at the top suggests no major M&A activity or fleet exits among the largest bulk haulers over the past 12 months. Ranks six through 10 shifted, with new entries appearing in the lower half of the top 10.

Depot Connect's climb stands out. The carrier moved from outside the top 250 for-hire fleets in 2025 to No. 160 in 2026, a jump of more than 100 positions. FleetOwner did not specify whether the gain came from organic growth, acquisitions, or a shift in how the company reports its fleet size. For a tank carrier, that kind of movement typically signals either a large contract win (chemical plants, fuel terminals, food-grade haulers) or the addition of equipment through a buyout.

Why tank fleets matter to the broader market

Bulk haulers operate in a different rate environment than dry van or reefer carriers. Liquid and dry bulk contracts tend to run longer, with rates tied to specific commodities (crude oil, chemicals, food-grade liquids, cement, grain). Spot exposure is lower than in general freight, which insulates tank fleets from the kind of per-mile rate swings that hit van carriers in 2023 and 2024. But it also means tank fleets feel commodity price moves and industrial production shifts more directly.

A stable top five suggests the largest bulk haulers maintained their customer base and equipment counts through a year when general freight carriers shed trucks and filed for bankruptcy at elevated rates. Tank operations require higher capital investment per truck (specialized tanks, cleaning equipment, hazmat certifications) and face stricter insurance underwriting, which creates a higher barrier to entry and exit than dry van.

What the rankings tell small-fleet tank operators

For owner-operators and small fleets running tank equipment, the FleetOwner 500 offers a snapshot of who controls capacity in the segment. The top 10 carriers set the floor for contract rates in major lanes and influence how shippers allocate volume. When a large tank fleet expands (like Depot Connect's 100-spot climb), it can tighten available loads for smaller operators in overlapping lanes, particularly if the growth came from a dedicated contract that pulled freight off the spot market.

Small tank fleets also face the same cost pressures as large carriers but without the volume discounts on insurance, equipment financing, and tank cleaning. If the top five held steady while a mid-tier carrier like Depot Connect surged, it suggests growth is happening in the middle of the market, not at the very top. That pattern often precedes consolidation, as mid-sized fleets buy smaller operators to reach the scale needed to compete for national contracts.

The FleetOwner 500 ranks carriers annually, using data from the prior calendar year. The 2026 list reflects fleet sizes and revenue from 2025 operations. Carriers submit their own data, which FleetOwner verifies against FMCSA records and public filings. The rankings do not include private fleets (carriers that haul only their own goods) or brokers.

How this ranking cycle compares to reefer and LTL

Tank fleets showed more stability at the top than other segments in the 2026 FleetOwner 500. C.R. England held the No. 1 reefer spot, but K.L. Breeden climbed to No. 6 and National Carriers entered the top 10, indicating more movement in the refrigerated segment. FedEx and UPS held the top LTL positions, with ArcBest climbing to No. 9 and Central Transport entering at No. 10, showing churn in the less-than-truckload rankings as well.

The contrast suggests bulk hauling saw less disruption in 2025 than temperature-controlled or LTL freight. That tracks with broader market data: reefer and LTL carriers faced steeper rate pressure and capacity adjustments as consumer spending shifted and inventory levels normalized post-pandemic. Tank fleets, tied more closely to industrial production and energy markets, followed a different cycle.

What small fleets should watch

Depot Connect's 100-spot jump is the data point to track. If the carrier releases details on how it grew (new terminals, acquisitions, contract wins), that will signal where demand is concentrating in the bulk market. For a 5- or 10-truck tank operation, knowing which lanes and commodities are drawing capital helps with equipment decisions and contract negotiations.

The stability at the top also matters. When the largest carriers hold position year over year, it usually means contract rates are stable enough to support their existing footprint without forcing expansion or contraction. For small fleets, that translates to a predictable rate floor, but also limited upside, the big carriers are not pulling back and leaving lanes open.
