Why this article is important: Antitrust has long been an issue in real estate. When new players attempt to innovate in the industry, it’s often too easy for old-school players to maintain their stranglehold on their access to information and users — ultimately to the detriment of real estate sellers, buyers, tenants and MLOs.
Antitrust patronage dogs the industry
Antitrust behavior in real estate is back in the news. This time, commercial real estate is getting the antitrust treatment, just not from regulatory agencies.
Antitrust rules are long-standing state and federal regulations designed to promote fair competition in the marketplace, a Teddy Roosevelt era awakening. When a player becomes too powerful, making it impossible for “little guys” to compete, that’s when the courts consider stepping in to stop what has become a monopoly, with power to control an entire industry to the exclusion of others.
Recently, you may recall the National Association of Realtors (NAR®) losing their fee-fixing case on antitrust violations.

In response, CREXi claimed CoStar is conducting antitrust activity, in violation of the Sherman Act, a federal law. Aside from having an oversized market influence, CoStar entered into exclusive arrangements in their dealings with brokers. The agreements prevented competitors of CoStar from accessing content and being able to compete. These dealings included:
- technological barriers constructed by CoStar that prevented brokers from freely publishing properties available for sale or lease on competing platforms; and
- contract language that directly or implicitly prohibited brokers from providing CoStar’s competition with properties for sale or lease.
CREXi claimed its only way to compete with CoStar was to unlawfully publish the photographs which appeared on CoStar’s website.
CoStar called CREXi’s antitrust claims a “sideshow” diverting attention from the real issue of copyright infringement on CoStar’s material. And…
