Summary

Compass Pressures MLS

In October 2025, Compass CEO Robert Reffkin emailed MLSs urging them to cut Zillow feeds unless Compass listings were shown.
Compass partnered with four MLSs—MRED, Realtracs, The MLS/CLAW and BrightMLS to feed private listings and will subsidize up to 100,000 agents joining MRED.
NWMLS chief executive Justin Haag condemned the MRED-Compass alliance as a tiered system that obscures homeownership, noting that MRED CEO Rebecca Jensen says rule enforcement applies to all.
