CoStar Group is expected to report second-quarter 2026 earnings in the final week of July. Revenue is forecast to reach $1.15 billion for the period ending June 30, 2026. This represents a 14.3% year-over-year increase from the $1.006 billion reported in Q2 2025. The company’s adjusted earnings per share are anticipated to land between $0.26 and $0.28. The consensus among analysts has remained stable for the past 90 days, suggesting firm expectations for the quarter. The report will test the resilience of the company's core commercial real estate data business. It will also measure progress toward consistent profitability in its residential expansion efforts.
Context — [why this matters now]
CoStar Group's earnings reports have become critical market health checks for the commercial real estate sector. The last time the company reported a significant deviation from expectations was in Q4 2023. It missed revenue consensus by 3.2% due to a sharp pullback in commercial transaction volumes. The current economic backdrop features a 10-year Treasury yield of 4.15%. The Federal Reserve's latest dot plot projects one more rate cut in 2026. The commercial property market faces persistent headwinds from high capital costs and refinancing challenges.
A primary catalyst for Q2 2026 focus is the integration of recent strategic acquisitions. CoStar completed its acquisition of a major European property data provider in March 2026 for $700 million. This move directly expands its international footprint outside North America. Another catalyst is the ongoing performance of Apartments.com. The residential listing portal now commands over 70% market share in the US. Its monetization efforts are crucial for offsetting slower growth in the commercial segment.
Data — [what the numbers show]
Analyst estimates from a compiled consensus provide a detailed snapshot of Q2 2026 expectations. Revenue is projected at $1.15 billion, with a tight forecast range from $1.14B to $1.16B. Adjusted EBITDA is expected to be $285 million. This implies a margin of 24.8%, a slight expansion from 24.1% in Q1 2026.
| Metric | Q2 2026 Estimate | Q2 2025 Actual | Change |
|---|
| Revenue | $1.15B | $1.006B | +14.3% |
| Adj. EPS | $0.27 | $0.21 | +28.6% |
| Adj. EBITDA | $285M | $242M | +17.8% |
CoStar’s full-year 2026 revenue guidance calls for $4.73 billion to $4.78 billion. The company held $4.9 billion in cash and short-term investments on its balance sheet at the end of Q1 2026. Its current market capitalization is approximately $30.5 billion. This compares to the Real Estate sector ETF (XLRE), which is down 2.1% year-to-date. CoStar stock is up 8.5% over the same period, outperforming its sector.
Analysis — [what it means for markets / sectors / tickers]
The earnings report will send immediate signals to related sectors and tickers. A strong beat on commercial data revenue would be bullish for commercial mortgage REITs like ARI and STWD. It could signal stabilizing property valuations. Conversely, a miss may pressure the stocks of property brokers CBRE and JLL. Their transaction fee income is tied to the same market data CoStar sells.
A key risk to the positive narrative is customer concentration. CoStar’s top 100 enterprise clients account for roughly 35% of its commercial segment revenue. A decision by a major client to reduce its subscription tier could materially impact future quarters. Another limitation is the high investment spend on residential growth. Apartments.com marketing expenses exceed $400 million annually. They pressure near-term profitability despite long-term market dominance.
Institutional positioning shows a divergence. Long-only funds have increased their holdings by 4% over the last quarter. Hedge funds, however, maintain a net short interest of 2.8% of the float. Flow data indicates options activity is elevated ahead of the report. There is significant volume in out-of-the-money call options expiring in August 2026.
Outlook — [what to watch next]
Specific catalysts following the Q2 report will determine the stock's trajectory for the second half of 2026. Management will host its quarterly earnings call on July 28, 2026. Analysts will seek an update on the European integration's contribution to revenue. The next major industry data point is the Q2 2026 commercial property price index from Moody's. It will be released on August 15, 2026.
Investors should monitor the company's implied revenue growth rate for Q3. Any guidance below 12% could trigger a selloff. A key technical level to watch is the 200-day moving average, currently at $78.50. A sustained break above $85.00 would require a significant earnings beat and a raised full-year outlook. The stock faces resistance at its 52-week high of $84.20 from January 2026.
Frequently Asked Questions
What does CoStar Group's earnings mean for retail investors?
Retail investors use CoStar's performance as a leading indicator for the broader commercial real estate investment trust (REIT) market. Strong commercial data sales suggest property managers and brokers are actively spending on market intelligence. This activity often precedes increases in leasing and sales transactions. A weak report could signal continued caution and pressure dividend yields for retail-focused REITs.
How does CoStar's projected growth compare to other data providers?
CoStar's 14.3% projected revenue growth outpaces the 8-10% growth seen in mature financial data peers like S&P Global's Market Intelligence division. It is slower than some niche software-as-a-service providers but is achieved on a much larger revenue base. The company's growth is primarily organic, whereas peers have relied more heavily on acquisitions in recent years.
What is the historical accuracy of earnings estimates for CoStar Group?
CoStar has met or exceeded revenue consensus estimates in 18 of the last 20 quarters. The two misses, in Q4 2023 and Q2 2021, were both tied to sudden macroeconomic shocks that reduced commercial real estate activity. The company's guidance is typically conservative, with actual results often coming in at the high end or above the provided range.
Bottom Line
CoStar's Q2 report will validate whether its aggressive expansion can overcome persistent commercial real estate sector weakness.
