What's Happening?
CoStar Group has initiated a legal battle against Zillow Group, accusing the latter of using over 46,979 copyrighted real estate photographs without permission. The lawsuit, filed on July 30, 2025, seeks compensatory and punitive damages that CoStar estimates could exceed $1 billion. CoStar claims that Zillow has utilized these images, many of which are watermarked, to bolster its rental listings business, potentially generating revenue through advertising and property management tools. This legal action is part of CoStar's ongoing efforts to protect its intellectual property, a strategy that previously resulted in a $500 million judgment against Xceligent in 2019. The lawsuit also involves third-party platforms like Realtor.com and Redfin, which Zillow allegedly syndicated the images to.
