What CoStar Group does

CoStar Group (NASDAQ: CSGP) is a publicly traded S&P 500/NASDAQ 100 company founded in 1986 and headquartered in Arlington, Virginia. The company operates as a global digital infrastructure provider for the real estate industry, delivering commercial real estate information, analytics, online marketplaces, and 3D digital twin technology. Its portfolio spans flagship commercial brands (CoStar, LoopNet, Ten-X, STR), multifamily rentals (Apartments.com Network of 11 sites), residential marketplaces (Homes.com, OnTheMarket, Domain), 3D spatial technology (Matterport), land and agricultural platforms (Land.com, AcreValue), and lease accounting solutions (CoStar Real Estate Manager, Visual Lease). The company serves brokers, lenders, investors, appraisers, multifamily landlords, homebuilders, hotel operators, and consumers across 86 offices in 14 countries, reaching 134+ million monthly unique visitors across its web properties.

The core technology platform combines 40 years of proprietary real estate data with AI-powered search (Apartments.com AI, Homes AI, both built on Microsoft Azure OpenAI), Matterport 3D digital twin technology covering 50+ billion sq ft in 177+ countries, and specialized vertical data assets (STR hotel benchmarking across 94,000 hotels and 12M rooms, AcreValue farmland data across 48 states). Revenue is generated primarily through subscription-based pricing with approximately 95% of commercial revenue subscription-based and near-90% renewal rates, supplemented by marketplace advertising (Apartments.com, Homes.com) and transaction fees (Ten-X). Distribution combines direct enterprise field sales for commercial data, a dedicated inside-sales force of 275+ for Homes.com, self-serve digital marketplaces, and strategic partnerships (eXp Realty's 300,000 agents via Homes.com).

The business model has expanded aggressively through M&A, with $1.6B for Matterport (Feb 2025), $1.9B for Domain Group (May 2025), and a pending $800M Zonda acquisition (announced May 2026, expected close H2 2026) extending the platform into 3D digital twins, Australian residential, and new home construction data respectively. FY2025 revenue reached $3.2B with FY2026 guidance of $3.78-$3.82B and adjusted EBITDA guidance of $780-$820M, following 60 consecutive quarters of double-digit revenue growth. The Homes.com residential expansion has been capital-intensive (estimated ~$5B cumulative spend by Third Point for ~$80M expected 2025 revenue), prompting a $1.5B share repurchase program and formation of a Capital Allocation Committee in response to activist pressure.
