Overview

• Compass filed an antitrust lawsuit in a New York federal court on June 23, alleging Zillow’s 24-hour listing ban relies on exclusionary tactics to stifle competition.
• Zillow’s policy, which took effect May 28 and is set to be enforced from June 30, bars any home from its site if it is not listed within 24 hours of public marketing.
• The brokerage warns that this requirement disrupts its three-phase marketing strategy, noting that about 35% of its listings rely on private or “coming soon” stages.
• Zillow maintains the requirement aligns with the National Association of Realtors’ 2019 Clear Cooperation rule and ensures consumers see all publicly marketed homes.
• Compass claims Zillow exploits its platform dominance by redirecting buyers to affiliated agents and collecting up to 40% of buyer agent commissions.
