US sues RealPage, claims rental-pricing algorithm used by landlords is illegal

The United States today sued RealPage, alleging that the software maker distorts competition in rental housing by helping landlords collectively set prices.

"To ensure they secure the greatest value for their needs, renters rely on robust and fierce competition between landlords. RealPage distorts that competition," said the lawsuit filed by the US government and eight state attorneys general. In a press release, the Justice Department said that "RealPage's pricing algorithm violates antitrust laws."

Attorney General Merrick Garland delivered remarks on the lawsuit. "When the Sherman Act was passed, an anticompetitive scheme might have looked like robber barons shaking hands at a secret meeting," he said. "Today, it looks like landlords using mathematical algorithms to align their rents. But antitrust law does not become obsolete simply because competitors find new ways to unlawfully act in concert."
