CoStar Group (CSGP) just rolled out Homes AI on Homes.com, giving buyers and renters a conversational voice or text experience that uses its property data and Microsoft Azure OpenAI tools to personalize home searches.

Despite the Homes AI launch catching attention, CoStar Group’s share price return has been under pressure, with a 30 day share price return of 30% and a 1 year total shareholder return of 39.4%. This suggests sentiment has weakened even as product development and governance changes respond to earlier concerns raised by activist investors.

With CoStar Group’s share price under pressure despite revenue growth of 11.6% and net income growth of 42.8%, as well as a discount to some analyst and intrinsic estimates, is the current weakness a potential opportunity or is future growth already priced in?

Most Popular Narrative: 43.3% Undervalued

CoStar Group's most followed narrative pegs fair value at $80.74 per share, well above the last close of $45.74, framing a wide valuation gap to unpack.

Aggressive investment in the Homes.com platform and rapid sales force expansion are enabling accelerated penetration in residential real estate, opening up a vast addressable market and creating meaningful opportunities for top-line growth and revenue diversification.

Integration of AI-driven features, Matterport's 3D technology, and advanced analytics across platforms is increasing user engagement, enabling higher-value product offerings and upsells, and improving client retention, which is positioning the company for elevated margins and increased net income over time.

Curious how that residential push, AI rollout, and long term margin rebuild all stack up numerically? The narrative leans on specific growth, profitability and valuation targets that are anything but casual.

Result: Fair Value of $80.74 (UNDERVALUED)

However, there are real pressure points, including activist calls to cut or exit Homes.com, along with concerns that higher marketing and headcount could keep margins under strain.

Another Check: Price To Sales Paints A Tougher Picture

While the popular narrative and our DCF model point to CSGP trading below fair value, the P/S ratio tells a different story. At 6.3x sales versus a fair ratio of 4.5x, the current price is rich, and it also sits well above the US real estate industry at 2.5x and peers at 1.7x. That gap suggests less room for error if growth or margins fall short, so which signal do you trust more?
