Available vehicles reach the highest levels in five years

Auction Inventory Hits Peak. Auto auction activity continued its upward trend in 2025, with both sales volume and inventory reaching notable milestones, according to the National Auto Auction Association (NAAA).

More than 8 million vehicles were sold through NAAA-member auctions last year, marking a 3% increase from 2024 and the third consecutive year of growth.

Strong Growth in Supply and Listings

Auction supply also expanded significantly, with 12.3 million vehicles offered for sale—up 4% year-over-year and the highest level recorded since 2021.

This increase highlights the growing role auctions continue to play in vehicle remarketing across the industry.

Digital and In-Lane Sales Continue to Expand

Of the total vehicles sold, 7.2 million transactions occurred in-lane, while 820,000 were completed through digital-only channels.

Notably, half of all in-lane sales involved online bidders, underscoring the continued shift toward hybrid and digital participation in auctions.

Commercial Vehicles Drive Momentum

Commercial inventory played a major role in 2025’s growth.

51.4% of in-lane sales were commercial vehicles, up 5.2% year-over-year

50.7% of digital-only sales were commercial units, rising 14.6%

At the same time, dealer vehicles represented a smaller share of digital-only sales compared to the previous year, signaling a shift in inventory mix.

Pricing and Performance Metrics Improve

Auction performance metrics also showed strength:

• Average sale price increased 5.3% to $13,800
• Conversion rates averaged 58.5%, holding relatively steady year-over-year
• The total gross value of vehicles sold rose 8.5%, surpassing $100 billion

Additionally, the average NAAA member auction sold around 25,000 vehicles, with many exceeding 30,000 units annually.

Market Resilience and Recovery

The report also pointed to a rebound in commercial vehicle sales following prior declines caused by pandemic-related disruptions in new vehicle production.

Overall, the data reflects a resilient and evolving auction market, with growing digital adoption and sustained demand supporting continued expansion.

Continued Growth Ahead

With rising inventory levels, strong demand, and expanding digital channels, auto auctions remain a critical component of the used vehicle ecosystem.

As the market continues to stabilize, auctions are expected to play an even larger role in connecting buyers and sellers across the industry.
