CarMax's Aug 2026 price cut lasted one month: its used premium is back to $2,000 as Bank of America turns bullish
The August narrowing reversed in a month, while CarMax's share of US used sales held at 4.17%.
CarMax's median used asking price in the US returned to $25,998 in Sep 2026, $2,000 above the US used median of $23,998, according to MarketCheck data. That is double the gap of one month earlier: in Aug 2026 the premium had narrowed to $1,008, the only month in the series where CarMax priced close to the wider US used market. MarketBeat reported on Oct 17, 2026 that CarMax (NYSE: KMX) carries a consensus brokerage price target of $57.85, and covered Bank of America's upgrade of the stock to Buy, which cited improved competitiveness and cost reductions. On the price-competitiveness part of that case, the MarketCheck read for Sep 2026 points the other way: the August narrowing reversed within a month, while CarMax kept taking share of US dealer-website used sales. For dealers pricing against CarMax, the working number is a $2,000 premium, not a $1,000 one.
What the data shows
| Month | CarMax used sold (units) | CarMax median ask ($) | US used sold (units) | US median ask ($) | CarMax premium ($) | CarMax share of US used sales (%) |
|---|---|---|---|---|---|---|
| Sep 2025 | 59,130 | 23,998 | 1,557,527 | 22,992 | 1,006 | 3.80 |
| Jun 2026 | 71,218 | 25,998 | 1,625,751 | 23,984 | 2,014 | 4.38 |
| Jul 2026 | 74,019 | 25,998 | 1,670,107 | 23,984 | 2,014 | 4.43 |
| Aug 2026 | 73,824 | 24,998 | 1,709,376 | 23,990 | 1,008 | 4.32 |
| Sep 2026 | 66,255 | 25,998 | 1,588,723 | 23,998 | 2,000 | 4.17 |
| Sep 2026 vs Aug 2026 | -10.3% | +4.0% | -7.1% | flat | +992 | -0.15 pts |
| Sep 2026 vs Sep 2025 | +12.0% | +8.3% | +2.0% | +4.4% | +994 | +0.37 pts |
Reading the table: CarMax's premium doubled back to $2,000 in Sep 2026, and its sales fell faster than the market's from Aug 2026, while year on year its growth still outpaced the market by about six to one. Every price here is a median advertised asking price, and the sold figures are the last asking prices of listings that left dealer websites, used as a sold proxy.
Why it matters
The August price was a one-month event. CarMax's median used ask was $24,998 in Aug 2026 and $25,998 in Sep 2026, a move of +4.0% in a month in which the US used median was flat at $23,998. Stores that re-spaced their own prices against a cheaper CarMax in August were pricing against a level that did not hold.
Share kept rising even with the premium back. CarMax's used sales rose 12.0% from Sep 2025 to Sep 2026, against 2.0% for all US dealer used sales, and its share of those sales rose from 3.80% to 4.17%. The premium widened over the same year, from $1,006 to $2,000, so the share gain did not come from carrying the cheaper asking price in the market.
Part of the premium is a different car. CarMax's Sep 2026 median sold vehicle had 39,476 miles, against 59,181 miles for the US used market in the same month. A buyer comparing a CarMax ask with the market median is not comparing like for like on mileage.
The lot is bigger and older than what sold. On Oct 19, 2026, MarketCheck live inventory data counted 87,505 used cars on carmax.com at a median ask of $27,899, with a median of 85 days on market. Earlier MarketCheck research counted 85,709 cars at $28,169 on Sep 28, 2026, so stock rose while the ask edged down. For live inventory, days on market measures the age of cars still unsold, which is not comparable with the 25-day median time to sale for cars CarMax sold in Sep 2026.
The month-to-month direction is worth noting. From Aug 2026 to Sep 2026, CarMax's sales fell 10.3% against 7.1% for the market, the same month its premium widened again from $1,008 to $2,000.
What to watch
- CarMax's Oct 2026 median ask. A return to about $25,000 would read as a pricing strategy; a hold at about $26,000 would read as Aug 2026 having been a one-month clearance, and rival stores can keep their current price spacing.
- The aged lot. A median of 85 days across 87,505 listings is where markdowns usually land first, so shoppers looking at CarMax's older stock have the most room to ask.
- CarMax's share of US dealer-website used sales. It was 4.17% in Sep 2026, down 0.15 pts from Aug 2026 and up 0.37 pts year on year.
- The US median ask itself, which sat at $23,998 in Sep 2026 after being flat from Aug 2026. The premium is a gap between two moving numbers, not CarMax's alone.
- CarMax's median sold mileage, 39,476 miles in Sep 2026 against 46,469 miles in Sep 2025. If sourcing shifts, the mileage share of the premium shifts with it.
How this was measured
Sales are listings that left US franchise and independent dealer websites. Auctions and private sales are excluded. Prices are median advertised asking prices.

The read uses MarketCheck data: national used sold summaries for carmax.com and for the whole US market, Sep 2025 and Jun to Sep 2026, plus a live inventory snapshot of carmax.com on Oct 19, 2026.
