$3.78–3.82B
guided 2026 revenue
CoStar Group guided to 2026 revenue of $3.78 billion to $3.82 billion, about 17% year-over-year growth at the midpoint, affirming in February 2026 the guidance it gave in January.
CoStar Group's brands include BizBuySell, which its 2025 annual report describes as a marketplace for operating businesses and franchises for sale (CoStar Group Form 10-K).
What this figure measures
The figure is CoStar Group's guidance for total company revenue for the full year of 2026, stated as a range of $3.78 billion to $3.82 billion, with year-over-year growth of approximately 17% at the midpoint. It is a forecast, first given on January 7, 2026 and affirmed in the company's fourth-quarter 2025 results release, not a reported result.
How it was produced
Guidance is management's own forward-looking projection, published in a results release that CoStar Group filed with the US Securities and Exchange Commission. It is neither an independent estimate nor an audited figure, and it reflects the company's expectations at the time the release was issued.
What it does not tell you
The guidance covers the whole company rather than any single marketplace, and the release does not break out BizBuySell, so it says nothing about the size of the business-for-sale or franchise-resale market itself. Guidance can be revised during the year; the actual result will only be known once CoStar Group reports it.
