CoStar Group, Inc. (NASDAQ: CSGP), a leading provider of online real estate marketplaces, information, analytics, and 3D digital twin technology, announced its continued support for Matterport Spaces across all media channels.

Zillow is again engaging in anti-consumer conduct, claiming that CoStar Group has “restricted the use of Matterport 3D virtual tours outside of CoStar-owned sites.” This is untrue. Matterport Spaces—i.e., our 3D virtual tours—purchased through Matterport may be displayed on any site.

If anyone signs up for a Matterport subscription and creates a Matterport 3D virtual tour—what we call a Matterport Space—they can post the Space wherever they like. These Matterport Spaces can be input into all MLSs for distribution on all IDX websites and portals, including Zillow. At least one MLS, CRMLS, has already issued a correction, confirming that its members may continue to use their Matterport Spaces on their listings.

Thousands of businesses leverage Matterport Spaces for a wide variety of uses, ranging from architectural design to construction management, insurance adjustment, industrial operations and manufacturing, and everything in between. Only CoStar Group media created for exclusive use on CoStar Group platforms, such as Matterport Spaces shot by CoStar Group photographers for Homes.com memberships or Apartments.com advertising, remain proprietary.

Gene Boxer, CoStar Group’s General Counsel, said:

“Zillow is trying to mislead agents to divert attention from five lawsuits filed against Zillow in the last four months: (1) Compass sued Zillow for its anticompetitive listing ban; (2) CoStar Group sued Zillow for massive copyright infringement; (3) a class of plaintiffs sued Zillow for their deceptive lead diversion through the use of the ‘contact agent’ button; (4) the FTC sued Zillow for entering into an anticompetitive agreement with Redfin; and (5) five states sued Zillow for the same anticompetitive agreement. Zillow’s recent partnership with ChatGPT is also being questioned by MLSs.

Zillow’s misstatements are a pretext to exclude a superior, competing product from its network. Resorting to these anticompetitive tactics against CoStar Group demonstrates that Homes.com and Matterport are succeeding.”
