Zillow's ChatGPT Integration: Redefining Real Estate Search or Violating MLS Policies?

Oct 8, 2025 at 6:56 PM

Zillow recently announced an integration with OpenAI's ChatGPT, allowing consumers to search for properties using artificial intelligence. Users can input property descriptions into ChatGPT, which then retrieves listings complete with photos, maps, and pricing, all powered by Zillow's data. This innovative approach differs from other AI integrations in the real estate sector, as Zillow's listing data is being utilized by an external platform, ChatGPT, rather than remaining exclusively within Zillow's ecosystem.

However, this development has not been without its critics. Industry expert Victor Lund from WAV Group voiced concerns, arguing that Zillow's transfer of MLS data to ChatGPT might infringe upon existing MLS agreements. Lund's primary contention is that Zillow's IDX licenses permit the display of MLS data solely on its own website and mobile application, not for transmission to third-party platforms like OpenAI's ChatGPT. He suggests this could be a violation of the cooperative principles underpinning the MLS system, comparing it to an unlicensed entity scraping and publishing MLS data. Zillow, conversely, maintains that its ChatGPT integration adheres to all existing MLS agreements, emphasizing that it does not license MLS data directly to ChatGPT, and that the new experience is designed to expand listing visibility and direct consumers back to agents.

The debate highlights a broader conversation within the real estate industry regarding the rapid advancement of technology and the relevance of long-standing MLS policies. Figures like Saul Klein, CEO of San Diego MLS, acknowledge the value of integrating with AI models like ChatGPT given their increasing popularity as search tools. Yet, he also underscores the importance of investigating potential misuses of MLS data, which could dilute its value and compromise the MLSs' role as data custodians. This situation prompts a critical re-evaluation of how current IDX rules, formulated decades ago, apply to contemporary technological innovations, potentially necessitating a dialogue to update these policies for the AI era.

This ongoing discussion underscores the delicate balance between fostering innovation and upholding established regulatory frameworks. As technology continues to evolve at an unprecedented pace, it becomes imperative for industries to adapt their policies to ensure fair play, data integrity, and sustained growth. Embracing new technologies while maintaining ethical standards and legal compliance is crucial for the future advancement of any sector, including real estate. This situation presents an opportunity for stakeholders to collaboratively shape a future where innovation and regulation coexist harmoniously, benefiting all participants.
