New-vehicle days’ supply tightened to 76 in May as sales accelerated faster than inventory grew, according to Cox Automotive’s latest market report. The daily retail selling rate rose 9.6 percent year over year and 6.5 percent from April, outstripping inventory additions and pulling supply lower across most brands.
Inventory reached 2.89 million units in May, up from 2.86 million in April and 13 percent higher than a year earlier. The modest month-over-month gain kept supply broadly in line with 2026 averages, but the faster sales pace changed the math: Days’ supply fell from February’s weather-distorted peak of 96 to 76 in May, the tightest reading since the first quarter.
The year-over-year inventory comparison tells a narrower story than it looks. Spring 2025 inventory was depleted by a sales surge that ran above 17 million seasonally adjusted annual rate in March and April, draining dealer lots. The 13 percent gain from that depressed baseline reflects a return to more orderly supply levels rather than renewed accumulation. Cox Automotive’s data shows inventory has remained within a relatively narrow range since January, allowing days’ supply to track sales momentum rather than stockpile growth.
Brand-level disparities remain pronounced. Nissan posted 82 days’ supply in May, down from both April and a year earlier, as sales accelerated and cleared inventory faster than the brand could replenish it. Toyota and Lexus continued to operate well below the industry average at 36 and 38 days respectively. Honda, Cadillac, Infiniti, and Chevrolet also remained below average.
The opposite pattern held at Stellantis, where Chrysler, Dodge, and Jeep posted materially higher supply levels year over year. Dodge led oversupplied brands with 142 days of supply, almost double the industry average, as inventory growth outpaced demand. The pattern is straightforward: Tighter supply where sales are working, looser supply where volume is not clearing inventory fast enough.
Pricing remained disciplined but not easier. The average listing price climbed to a 2026 high of $49,307 in May, up 1.2 percent year over year. Kelley Blue Book data showed average transaction prices fell 0.5 percent month over month to $49,220, the smallest annual gain of 2026 and well below the typical May increase. MSRP growth was subdued at 1.6 percent year over year. Roughly 56 percent of available inventory was priced below $50,000, and 25 percent sat in the $30,000-to-$40,000 range, indicating volume remains concentrated in the core of the market even as the average stays elevated.
Incentives rose to 7.1 percent of average transaction price in May, continuing a gradual climb but not to a level that suggests widespread distress. Cox Automotive framed the incentive trend as selective support: automakers are deploying spending to sustain demand while pricing strength remains concentrated in high-volume segments such as midsize SUVs, compact SUVs, and full-size pickups.
The market looks balanced on paper but remains constrained in practice. Demand is holding up better than many forecasters expected, supported by a solid labor market and wealth effects at the higher end, yet elevated financing costs and household budget pressure continue to cap how far that strength can carry. For automakers, the takeaway is that inventory discipline is working not because the market has become easy, but because sales are moving well enough to prevent inventories from building meaningfully. The question is whether that equilibrium holds when the next round of affordability pressure arrives.
