Thesis Summary

CoStar's operating trajectory improved materially in Q2 2026: revenue increased 18% year over year to $925 million and adjusted EBITDA increased 116% to $184 million. The residential portfolio reached an important profitability inflection while the core company continued double-digit growth. The counterweights are the reduction in full-year revenue guidance, only modest sequential growth in net new bookings, execution risk around Homes.com sales-force changes, and integration risk following the $800 million cash acquisition of Zonda. The resulting stance is Hold: operating leverage is becoming visible, but sustained revenue execution and successful integration must be demonstrated before adopting a more constructive recommendation.

Bear CaseDownside scenario
$25.0020%

Revenue falls below the revised guidance floor as sales-force changes, Ten-X restructuring and softer marketplace demand constrain bookings; residential profitability reverses or Zonda integration costs delay the planned margin expansion.

Base CaseCentral scenario
$37.1056%
Matches the consensus mean

CoStar delivers within its revised 2026 guidance ranges, with continued double-digit revenue growth and improving adjusted EBITDA, while residential profitability and Zonda integration progress unevenly but remain constructive.

Bull CaseUpside scenario
$53.0024%

CoStar reaches the upper ends of its revised 2026 revenue and adjusted EBITDA ranges, residential profitability proves durable, Homes.com monetization accelerates after sales-force optimization, and Zonda expands the new-home data and marketplace opportunity without disrupting margin expansion.

Scenarios are anchored to street consensus at the research date, with our probabilities and rationale.

Key Investment Risks
  • FY2026 revenue guidance was reduced to $3.715 billion-$3.755 billion from the $3.78 billion-$3.82 billion outlook issued in January 2026.
  • Q2 net new bookings were $69 million, only 3% above Q1 2026, leaving revenue execution sensitive to Homes.com sales-force changes and the Ten-X restructuring.
