The Listing Wars Are Back. Which Side of the Data Flow Is Your MLS On?
The Zillow-CIH conflict was not the disease. It was the symptom. Clear Cooperation, as written and enforced, forced brokers representing more than half of the nation’s listing inventory to choose between the MLS and their own go-to-market strategies. They made their choice. Compass International Holdings called Rocket, not their MLS. Keller Williams, RE/MAX, BHHS, United Real Estate, Side, and eXp followed. The listing data supply chain is being restructured right now, without MLS leadership at the table.
The solution is not complicated, but it requires honest governance and the will to act before the inventory is already somewhere else. MLSs that implemented formal Coming Soon infrastructure before this crisis, like Austin Board of Realtors, OneKey MLS, and MRED, are watching this unfold from a position of strength. Their broker participants are not the ones cutting emergency distribution deals with national portals. That is the return on investment for getting the policy right early.
Victor Lund, Co-Founder and CEO of WAV Group, has spent more than two decades advising MLSs, brokerages, and real estate technology companies on listing data strategy and MLS policy. His new 2026 report delivers the strategic framework every MLS CEO and board member needs right now.
What you will find inside:
- The data behind delayed listings and why the premise that drove Clear Cooperation was wrong from the start
- A seven-step strategic framework your board can act on before the next portal announcement reshapes your market
The portals already decided which side of this they are on. Now it is your turn.
