Truckload spot rates hit all-time record $3.83 per mile as freight market surges

US truckload spot rates reached an all-time record of $3.83 per mile in early June 2026, according to FreightWaves' SONAR National Truckload Index, surpassing the peak set during the COVID freight boom and marking the tightest domestic trucking market in recorded history. The move came in a single session, with rates jumping $0.09 per mile overnight, and multiple data sources confirm the reading is not a measurement anomaly.

FreightWaves founder Craig Fuller, reporting on the milestone at the launch of the network's daily show, noted that linehaul-only rates, which strip out fuel and reflect actual carrier cash flow, have been rising since November, making the surge structurally real rather than a fuel-cost illusion. The rate strength signals that the multi-year carrier downcycle that followed the post-COVID crash has decisively ended.

Three data points define the severity

Tender rejections climbed to 17.55%, the highest since the COVID era, according to NavilinkGlobal, meaning nearly one in five contracted loads is being refused by carriers choosing higher-paying spot freight instead. When rejection rates reach that level, it signals that the gap between contract and spot pricing has grown wide enough for carriers to risk long-term relationships.

The Logistics Managers Index placed its Transportation Prices reading at 96.0, which NavilinkGlobal described as the fastest rate of expansion ever recorded for any metric in the index's nearly 10-year history. The index uses a 50-point neutral baseline, with 100 representing the maximum possible rate of increase; a reading of 96.0 leaves almost no headroom. Transportation Capacity, measured separately, contracted sharply to 31.7.

Uber Freight projected that spot rates will remain 20–25% above year-ago levels for the remainder of 2026, per NavilinkGlobal. That forecast, if accurate, means shippers cannot wait for normalization and must adapt procurement strategies to a structurally higher cost environment.

Diesel, produce, and a thinner carrier base are the primary drivers

The national average diesel price stood at $5.35 per gallon according to the US Energy Information Administration data cited by NavilinkGlobal, up $1.899 year-over-year, with California reaching $7.051 per gallon and New England at $5.731 per gallon. FreightWaves reported that diesel briefly reached $5.54 per gallon at the retail pump following a war-driven price spike, though wholesale rack prices have since cooled faster than retail, a spread FreightWaves pegged at a record $1.78 per gallon that is generating meaningful margin gains for carriers on cost-plus fuel arrangements.

Produce freight competing for refrigerated capacity ahead of the traditional summer peak is compounding the squeeze. When that seasonal shift overlaps with peak-season cargo imports from Asia, the result is a capacity crunch across dry van, refrigerated, and flatbed equipment simultaneously.

C.H. Robinson's April 2026 freight market update identified California, Texas, and Arizona as structurally tighter than the national average. In California, diesel running roughly 40% above the national average has raised carrier cost per mile materially and driven higher tender rejections as contract fuel programs lag real-time inflation. In Texas, enforcement intensity and border-area compliance scrutiny are prompting carriers to selectively avoid lanes unless pricing compensates for the added risk.

March data shows the build-up was already underway

DAT Freight & Analytics reported in April that truckload volumes rose across all major equipment types in March, with its Truckload Volume Index showing van demand up 12% from February, reefer up 7%, and flatbed up 18%. Spot rates reached two-year highs at that point, with the average spot van rate at $2.52 per mile, a figure that has since been substantially eclipsed by the June record.

Contract rates also moved sharply higher in March, with the contract van rate reaching $2.72 per mile, up 20 cents month over month, and the contract flatbed rate hitting $3.43 per mile, up 30 cents, per DAT. Adamo advised shippers and carriers entering RFP season to price contracts based on forward market expectations rather than current conditions, and to build in adjustment mechanisms.

Freight shifts to rail, and runs into a new wall

As trucking costs climbed, shippers redirected volume to domestic intermodal, and rail networks absorbed the impact. Domestic container moves grew 9% year-over-year in March and April combined, according to IANA data cited by WTO-MWW. In Southern California specifically, Union Pacific's domestic intermodal volume surged more than 20% year-over-year, per Rail State data referenced by WTO-MWW.

Union Pacific responded on June 12 by announcing a $500 peak season surcharge on shippers moving fewer than five loads per week using UP-owned EMP and UMAX domestic containers originating in Southern California, effective June 21. WTO-MWW noted this is the earliest UP has imposed a peak season surcharge since 2021. Simultaneously, UP declared Chicago, Laredo, and all of California as constrained markets with strict weekly capacity commitments.

UP also raised spot prices across more than 100 intermodal lanes effective June 17, averaging nearly 12% increases, with 40 Southern California lanes seeing increases approaching 25%, according to WTO-MWW. The equipment shortage stems from the downturn period when UP stacked idle containers; reactivating them has not kept pace with the speed of demand recovery.

Drayage emerges as the next constraint

Shippers who secure intermodal rail capacity may face delays at the final leg. WTO-MWW identified drayage, the short-haul trucking connecting railheads to warehouses, as the weakest link in the intermodal chain. Drivers who exited during the downturn have not returned, and FMCSA enforcement against non-domiciled commercial driver's licenses has removed additional capacity from the pool, with California among the hardest-hit states.

FreightWaves reported similar structural observations from Webb Estes, president and COO of Estes Express Lines, who described last week as a company tonnage record with volumes up roughly 7.5% after the firm had been essentially flat just two months earlier. Estes noted that both retail and manufacturing are running strong simultaneously, an outcome he had not anticipated given higher prices and fuel costs, with grocery, construction, and the broader consumer base all moving freight.

The Section 122 tariff surcharge on US imports, set to expire July 24, is adding urgency. WTO-MWW explained that importers uncertain about what follows, whether expiration, extension, or replacement mechanisms under Section 301 or Section 232, are pulling shipments forward regardless, directing additional international cargo toward West Coast ports and into the same domestic container pools Union Pacific is now rationing. The convergence of trucking cost pressure, tariff-driven frontloading, and transloading activity on a single equipment pool is reshaping logistics planning timelines across the industry.
