The latest Q2 earnings reports from major trucking and rail carriers paint a clear picture: the freight market is tight, and rates are rising. But the driving force is not surging demand — it is a capacity-driven tightening cycle that one FreightWaves analyst expects to hold through at least 2027.

According to SONAR data, spot rates are sitting around $3.53 per mile against an annual average of $2.79. Contract rates have risen 18% year over year, with the SONAR contract rate index at 269 linehaul compared to an annual average of 241 — a substantial move for the contract market when measured from August 2025. Tender rejections remain elevated at 15.44%, a metric that measures how frequently carriers turn down offered loads and serves as a widely used indicator of how tight available capacity is.

JB Hunt and Knight-Swift Deliver Strong Results

JB Hunt, which reported July 15, posted a 19% year-over-year revenue increase and beat earnings estimates by nearly 10%. Intermodal served as the primary growth engine, with volumes rising 10% and operating income climbing sharply.

Knight-Swift (KNX) also beat expectations. Revenue was up 12.6% year over year, and consensus estimates were exceeded by more than 20%. KNX's operating ratio improved from 93.8 to 91.4. Management attributed the gains to regulatory and compliance pressures forcing non-compliant capacity out of the market, creating room for rate increases among compliant carriers. KNX also cited double-digit contract rate gains, higher spot rates, and rising tender rejections. The company specifically noted that contract rate increases began in June and that momentum has continued into July.

Class 1 Railroads Report Broad-Based Growth

Three Class 1 railroads reported positive results:

• Union Pacific: 12% revenue growth year over year with 4% volume growth
• CSX: 10% revenue growth year over year with 6.1% volume growth
• Norfolk Southern: 11% revenue growth year over year

The analyst attributed rail strength in part to mode conversion, as shippers shifted loads to intermodal amid rising truckload rates. Conference call commentary from the railroads highlighted strong volumes in both consumer goods and industrial products, the latter consistent with what FreightWaves has described as an industrial renaissance.

Spot Rates and Tender Rejections Show Seasonal Plateau

While spot rates have plateaued around the $3.50 mark and tender rejections have stabilized near 15.5%, the analyst characterized both patterns as normal July seasonality. Even so, tender rejections at 15.44% remain historically elevated, and contract rates continue their upward trajectory. The 18% one-year increase in the SONAR contract rate index represents a significant move for a market segment that typically changes more gradually, as contract rates are negotiated on fixed terms between shippers and carriers and tend to lag spot market movements.

Capacity Constraints Persist

A FreightWaves earnings summary quoted KNX management: "Before adding any new tractors, management noted that there is significant opportunity to enhance utilization, particularly since some trucks remain unseated."

This observation underscores a defining feature of the current cycle: capacity is not returning quickly even as rates rise. In typical freight cycles, elevated rates attract new entrants and prompt existing fleets to expand, eventually rebalancing supply and demand. Several structural barriers explain why that normal market response has not materialized this time:

• Regulatory hurdles: Additional regulation around CDL, DOT, and MC number requirements has raised barriers to entry for new carriers.
• Fleet strategy: Large fleets are prioritizing utilization of existing equipment over expansion.
• Driver shortages: Driver recruiting and retention remain difficult, leaving trucks unseated even at major carriers.

Unlike previous freight cycles driven by demand surges, this tightening has been caused by a decrease in available capacity — a dynamic that the analyst described as unlike anything seen before.

Fuel Costs Add Another Pressure Point

Brent crude oil hit $100 a barrel following Red Sea attacks. SONAR fuel indices show retail rates rising faster than wholesale rates, creating a gap that the analyst said presents a short-term arbitrage opportunity for fleets purchasing wholesale fuel. That gap is expected to persist until wholesale prices catch up.

Outlook

The analyst expects the capacity-driven tightening cycle to continue well into the cycle, pointing to sustained strength across key metrics: "All signs pointing towards a continued really strong freight market where we expect contract rates to continue to rise, spot rates to remain elevated, tender rejections to remain elevated." For carriers, the environment represents an opportunity to return to rate levels that support profitability.
