CarMax's revenue has grown at a compound annual rate of 10.3% since fiscal 2000, driven by customer-friendly sales practices and technology. In 2025, it had 3.6% US market share of zero to 10-year-old vehicles. Its share was down 10 basis points from 2024 as the firm has not done a great job messaging its omnichannel capabilities, something new CEO Keith Barr must improve, along with making the online shopping process easier.
