This week a federal judge denied Zillow's motion for a preliminary injunction against MRED and Compass, and the trade press ran a clean headline: MRED wins, Zillow loses. True — but only in a limited sense. In the context of a case that's nowhere near a final verdict, these are all lower-case w's and l's.

I went back to the three questions I carried into that courtroom. Did Compass and MRED conspire to weaponize a Chicagoland MLS's rules against Zillow's listing access standards? From the gallery it sure looked coordinated — the billboard mock-ups, the out-of-state listings entered right before the feed got cut. But Judge Tharp's 54-page opinion draws a hard line: complaining isn't coordination, and even coordination isn't conspiracy. Legally, no agreement. I'll still go on the record: I don't like how Compass is conducting business. In my house, we call maneuvering like that manipulation.

On harm and seller choice, the court was blunt. Zillow's harm was "entirely avoidable." Transparency — a word repeated 300+ times in the briefs — "is not, standing alone, a goal of the antitrust laws." And a lower price from a strategy "the seller themselves chose" isn't necessarily consumer harm. That phrase is doing a lot of work; a choice isn't an informed choice just because the seller technically selected it.

Here's what never enters the analysis: the buyer. So it leaves a heavier question. Whose job is it to make sure every buyer can see every home, and every seller understands the trade-offs they're agreeing to? Not NAR. Not the MLSs. Not Zillow. The honest answer is: nobody. No one in this industry is responsible for market transparency — we're left depending on the virtue of the people who run it, and from where I sit, virtue is in short supply. That's the real loss this week, and it's for consumers. Capital L.
