CoStar Group (NASDAQ: CSGP) has launched its commercial real estate intelligence platform in France, targeting what the company describes as an estimated €300 billion market.

The launch follows CoStar Group's acquisitions of BureauxLocaux and Business Immo, and draws on more than $5 billion in proprietary data and technology investment made over four decades. The French platform covers office, logistics, and hospitality sectors across major metropolitan areas including Greater Paris, Lyon, and Marseille.

At launch, the platform provides access to more than 290,000 properties tracked, 385,000 commercial tenants, 90,000 availabilities, 75,000 lease and sales comparables, and 134 market and submarket analytical reports.

Globally, the CoStar platform tracks 9 million properties, 8 million commercial tenants, 2 million property owners, 7 million lease activities, and 5 million sales comparables, according to the company.

"France is one of the most important real estate markets in the world, and we are delighted to bring to France the same platform that has transformed how commercial real estate is transacted in the United States, the United Kingdom and Canada," said Andy Florance, Founder and CEO of CoStar Group. "Commercial real estate operates across borders, and CoStar's subscriber base of over 320,000 CRE professionals around the world will now find it easier to evaluate opportunities in France."

CoStar Group, headquartered in Arlington, Virginia, reported $3.2 billion in revenue in 2025 and operates in more than 15 countries. The company's websites attracted 131 million average monthly unique visitors in the first quarter of 2026.
