Fair value as of: Aug 13, 2026
From 15 valuation models · updated yesterday
Fair value updated Aug 13, 2026, revised from $4.75 to $4.64 (−2.3%) since Jul 18, 2026. Share price +19.4% over the past month.
A solid business, but screening 86% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case ($8.10). The favourable scenario is already priced in.
- Solid but not exceptional quality (52/100) and above fair value, neither a clear bargain nor a standout compounder.
- A fairly wide model range ($3.33 to $8.10) leaves room in how you read the outcome.
- As a real-estate business, asset- and dividend-based methods carry more weight here than a standard DCF.

Analysis
CoStar Group (CSGP) currently trades at $33.05, while our model-based Fair Value estimate is $4.64, implying the stock looks roughly 86.0% overvalued today. The Quality Score stands at 52/100 (solid quality), in the Real Estate sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: high).
Over the trailing twelve months, CoStar Group generated revenue of $3.4B at a net margin of 0.7%. Revenue grew 22.5% year over year. It earns a return on equity of 0.3%. The balance sheet holds a net cash position of $589M. Fundamentals as of Aug 13, 2026
Our scenario range runs from $3.33 (bear case) to $8.10 (bull case); at $33.05, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 66% below its 52-week high and 5% above its 52-week low, currently below its 200-day average. For context, the median of 10 Real Estate peers we cover trades at 15% fair-value upside, at -86%, CSGP screens richer than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
All 15 models by family
Widest divergence: Asset-Based ($13.67) versus Multiples ($0.2900). Highest evidence: Growth DCF (80).
