Let’s see how things have shaped up for CSGP before the announcement.
Factors to Note Ahead of CSGP's Q1 Results
CoStar Group’s first-quarter performance is likely to have benefited from its robust portfolio of marketplaces, including Apartments.com, LoopNet and Homes.com.
Strong momentum across both the commercial and residential segments, along with the successful integration of recent acquisitions, including Matterport and Domain, is expected to have positively impacted the company’s top-line growth. The commercial segment is expected to have generated $470-$475 million in revenues, reflecting a 16% increase from the first quarter of 2025. The residential segment is projected to have reached $420-$425 million, marking a 31% year-over-year rise. This growth is likely to have been underpinned by the continued expansion of sales teams, which grew by nearly 800 in 2025.
The commercial segment is poised for growth, driven by investments in new markets and product launches. CoStar Group is expanding its presence in Australia, increasing its footprint in Europe and launching innovative products such as lease benchmarking, new homes information modules and STR profitability features. The CoStar sales team grew 20% year over year to 492 reps, supporting further revenue acceleration.
Homes.com is witnessing rapid growth, with increasing unique monthly visitors, improving user engagement and rising subscription numbers. In the fourth quarter of 2025, it reached an average of 108 million unique monthly visitors. In less than a year, Homes.com has grown into the second-largest residential real estate marketplace in the United States, highlighting the success of CoStar Group’s aggressive investment and digital strategy. This momentum is expected to have continued in the to-be-reported quarter.
However, challenging macroeconomic uncertainties, including high interest rates, elevated mortgage rates, persistent inflation and ongoing headwinds in the commercial real estate market, are expected to have affected revenue growth.
