An independent two-stage DCF analysis by a frontier AI model.
CoStar Group has long dominated the commercial real estate data market, building a proprietary database that functions as an irreplaceable utility for brokers and investors. This core business throws off immense, predictable cash flow.
The true upside lies in its aggressive pivot to the consumer residential market. By heavily investing to scale Homes.com—and leveraging the proven playbook it used with Apartments.com—CoStar is attempting a hostile takeover of a massive new TAM. The current valuation appears to penalize the company excessively for its near-term marketing spend while underestimating the long-term cash flow potential of establishing a dominant, integrated real estate portal.
A 15.0% growth rate reflects CoStar's incredibly strong, high-margin commercial real estate SaaS business and its massive ongoing expansion into the residential portal market with Homes.com. The transition of Homes.com from a heavy investment phase to monetization is expected to drive substantial free cash flow acceleration.
A 9.0% discount rate balances the company's near-monopoly status and recurring revenue in the commercial space against the fierce, expensive competition it faces as it attempts to disrupt entrenched players like Zillow in the residential market.
3.5% is a robust terminal rate for a digital monopoly. Assuming CoStar successfully cements Homes.com alongside its commercial and multifamily assets, it will benefit from immense, highly scalable, two-sided network effects in perpetuity.

Gemini anticipates that the massive upfront marketing investments in Homes.com will eventually taper, while the platform begins to monetize heavily. This, combined with the steady, high-margin growth of its core commercial suite, warrants an aggressive cash flow projection.
A 9.0% discount rate was selected. While the commercial business is incredibly stable, the residential expansion carries significant execution risk and requires competing against formidable, well-capitalized incumbents like Zillow.
