Following the launch of Homes.com Ai earlier in the year, CoStar introduced Apartments.com Ai in June. Residential revenue was $444 million in Q2, up 33% year-over-year, while Homes.com revenue grew 66% year-over-year to $28.5 million. “The outperformance in adjusted EBITDA overall was driven by actions to reduce personnel costs and continued operating efficiencies,” said Lown. “Taken together, these actions moderated near-term revenue growth, but we believe they position our businesses to generate increased revenue growth over time, leading to better long-term profitability.” For the third quarter of 2026, the company projects revenue between $935 million and $945 million, representing approximately 13% year-over-year growth.
