AI Adoption And International Expansion Will Gradually Reshape Long Term Real Estate Marketplaces

The analyst price target for CoStar Group has been reduced by approximately $39, with analysts citing softer assumptions for revenue growth and valuation multiples, ongoing pressure on Homes.com traffic, and external competitive and macro headwinds, even as core commercial platforms and Apartments.com are described as more resilient.

Analyst Commentary

Recent commentary on CoStar Group shows a clear split in sentiment, with some firms still positive on the long term opportunity while a group of bearish analysts focus on execution risks in residential, slower bookings, and rising competitive pressure, particularly around Homes.com.

On the more constructive side, Goldman Sachs trimmed its CoStar Group price target to US$46 from US$54 but maintained a positive stance, pointing to a divergence inside the residential portfolio. Homes.com traffic is described as under pressure and potentially vulnerable as marketing spend is expected to ease in 2026. In contrast, Apartments.com is viewed as maintaining more stable growth with lower incremental investment and support for margins and earnings. Benchmark also initiated coverage with a Buy rating and a US$45 price target, emphasizing CoStar Group's role as an information platform provider to the commercial real estate industry and commenting that the residential segment EBITDA is expected to move toward profitability over time.

At the same time, several large banks and research houses have reset expectations. Wells Fargo lowered its target on CoStar Group to US$26 from US$33, pointing to Q2 bookings that are expected to be below Street estimates, in part because of a tough comparison period and still improving sales force productivity. The firm also highlighted the risk that revenue in 2026 could land toward the low end of prior guidance. Other adjustments include a cut to US$37 from US$42 at BofA and reductions from Citi, Stephens, Baird, JPMorgan and Keefe Bruyette, all contributing to a broad recalibration of valuation assumptions.

Competition for online real estate traffic is another recurring theme. Keefe Bruyette flagged Google's expansion of home listings ads across the U.S. as a setback for real estate portals, particularly for companies focused on buyer agent leads. BTIG separately pointed out that Google's testing of for sale home listings in mobile search, with monetization through agent lead tools, could pressure traditional portal models for both CoStar Group's Homes.com and Zillow, especially if those listings are surfaced inside AI driven results. While those firms also note CoStar Group's diversified business mix, the tone around residential portal competition is cautious.

Stepping back, the analyst debate around CoStar Group now centers on how quickly residential economics can improve, whether marketing spend cuts at Homes.com slow user trends further, and how much value investors should assign to the more resilient commercial data and Apartments.com franchises as overall growth expectations reset.

Bearish Takeaways

• Bearish analysts have cut CoStar Group price targets across the board, with reductions to levels such as US$26, US$37 and other lower ranges from prior targets, reflecting a more conservative stance on valuation as growth expectations are reset.
• Several firms expect Q2 bookings to come in below prior Street estimates, citing a difficult comparison period and only gradual progress in sales force productivity, which they see as an execution risk for hitting future revenue goals.
• Concerns around Homes.com are central, as bearish analysts highlight ongoing traffic pressure and the possibility that reduced marketing spend in 2026 could further limit growth, raising questions about the payback on prior investment.
• Competition from Google home listings ads and alternative lead generation channels is viewed as an additional headwind for CoStar Group's residential portals, feeding into cautious views on growth durability and margin expansion in that segment.
