Shares shifted sharply higher Monday as investors piled into CoStar Group ahead of its Q2 2026 earnings report tomorrow, betting that the real estate data giant's costly residential gamble is finally about to pay off. The stock surged 5.9% to $29.30, rebounding from a multi-week slide that saw it trade as low as $27.14 last week — a fraction of analyst targets that average roughly $46, implying over 50% upside from current levels.
The Residential Unit Is on the Verge of Breaking Even — a First
CoStar guided Q2 residential revenue of $443–$448 million (up 32–34% year-over-year), with its residential adjusted EBITDA — a measure of operating profit before certain charges — expected to land between breakeven and $10 million. That matters because management told investors in April that the residential segment would reach profitability in Q2 2026 , after years of heavy losses funding its home-search platform. Confirming that inflection tomorrow would reframe the entire bull case.
The Home-Search Platform Grew Fast but Burned Billions
CoStar plans to reduce net investment in its home-search platform by more than $300 million in 2026, down from $850 million in 2025.
Despite a 337% jump in subscribers since early 2024, the company doesn't expect the platform to reach positive adjusted EBITDA until 2030. Activist investors from Third Point and D.E. Shaw have advocated for increased operational efficiency and clearer paths to profitability , pressuring the board to tighten spending.
Wall Street Expects a Big Earnings Jump — and Beats Are the Norm
Consensus estimates project earnings of $0.28 per share, a 65% increase from a year ago.
CoStar has beaten estimates in each of the last four quarters, by an average of roughly 23%.
Last quarter, revenue hit $897 million, up 22.5% year-over-year , and management raised full-year adjusted EBITDA guidance to $780–$820 million.
A $1.5 Billion Buyback Provides a Floor — in Theory
The board authorized a $1.5 billion stock repurchase program after completing a $500 million buyback in 2025. At a ~$12 billion market cap, that is a meaningful signal — but only if cash generation keeps pace and residential losses don't widen. CoStar was removed from the Nasdaq-100 index in May after a 57% decline in market value over the prior year , underscoring how much credibility still needs rebuilding. Tomorrow's numbers will show whether patience is finally being rewarded — or if the rally is premature.
