If you’ve noticed a sudden disappearance of 3D tours on certain listing sites lately, you aren’t imagining it. There is a high-stakes "listing war" happening between the industry’s biggest players—Zillow and CoStar (the parent company of Homes.com and Matterport)— and unfortunately, NYC agents and property managers are often the ones caught in the crossfire.

Here is the breakdown of the situation and why choosing the right virtual tour partner has never been more critical for your StreetEasy and Zillow presence.

The Conflict: Matterport vs. Zillow

In early 2025, CoStar Group (which owns Homes.com) completed its acquisition of Matterport. Since then, a major rift has formed between CoStar and Zillow.

• The Dispute: Zillow recently paused the integration of many Matterport 3D tours, citing concerns over CoStar's updated terms of service.

• The Claim: Zillow suggests that CoStar is restricting how these tours can be shared on competing platforms.

The Reality for Agents: While the giants argue over APIs and data rights, your listings could be losing their most valuable marketing asset. If you rely on Matterport, your 3D tour might show up on Homes.com but remain "broken" or missing on Zillow and StreetEasy.
