CoStar Group Invests in Wikicasa, Italy’s Agent-Backed Real Estate Marketplace

Transaction will result in an approximately 30% stake in the company and support innovation and digital transformation in the Italian real estate market

MILAN, July 01, 2026--(BUSINESS WIRE)--CoStar Group, Inc. (NASDAQ: CSGP), a global leader in online real estate marketplaces, information, analytics and 3D digital twin technology in the property markets, today announced an investment in Wikicasa, Italy's agent-backed real estate marketplace. The transaction will result in CoStar Group acquiring an approximately 30% stake in Wikicasa. Wikicasa's shareholder base includes Italy's leading real estate agencies - including Tecnocasa Group, Gabetti Group, RE/MAX Italy, and Tempocasa.

Wikicasa.it is an agent-driven platform that brings together leading real estate professionals across Italy to deliver a high-quality, data-rich marketplace of over 600,000 listings, more than 100,000 of which are commercial. It provides consumers with comprehensive property listings while equipping agents with modern data and intelligence tools to market properties and connect with buyers, sellers, landlords and tenants.

CoStar Group operates some of the world's leading online residential and commercial real estate marketplaces, including Homes.com and Apartments.com in the United States, Domain in Australia, OnTheMarket in the United Kingdom, and LoopNet, the most trafficked commercial real estate marketplace globally. Through these platforms, CoStar Group has demonstrated a consistent ability to build scale, increase transparency, and drive efficiency across property markets worldwide.

The investment brings together Wikicasa's strong local network and expertise with CoStar Group's technology, scale and global marketplace reach. As an initial step, this will create opportunities to broaden the visibility of Wikicasa's commercial listings through LoopNet, helping connect Italian properties with a wider global audience. Furthermore, while Matterport is already used by some of Italy's real estate agencies, Wikicasa's network will accelerate the adoption of Matterport's immersive 3D digital twins and artificial intelligence technologies across both the commercial and residential markets in Italy.

"We are delighted to have reached an agreement to invest alongside Italy's leading agents in Wikicasa. We've been impressed with what the shareholders and management team have achieved to date and believe there is a significant opportunity to create value by bringing our technology, global scale, and continued focus on innovation to the Italian property market," said Andy Florance, Founder and Chief Executive Officer of CoStar Group. "LoopNet is the obvious place to start because we know that commercial real estate transactions cross borders, and LoopNet brings an engaged audience of over 13 million monthly unique visitors who are already searching for their next space across the world. Soon, they will be able to extend that search into Italy. LoopNet's audience will also grow to include Italian companies searching in their markets or abroad."
