Ruling Issued
A federal judge denied Yardi Systems summary judgment in a multifamily rent-pricing antitrust suit, letting renters pursue fuller discovery into its RENTmaximizer software.
On October 13, 2026, U.S. District Judge Robert S. Lasnik denied Yardi Systems, Inc.'s motion for summary judgment in a proposed class action alleging its RENTmaximizer (later Revenue IQ) software let competing multifamily landlords coordinate rents using pooled, non-public pricing data. The ruling sends the case, filed in September 2023 by named plaintiffs McKenna Duffy and Michael Brett, into a fuller round of discovery, and follows a December 2024 denial of Yardi's motion to dismiss that found the claims plausibly allege a per se antitrust violation.
Proposed nationwide class action; summary judgment denied
Why it matters: The decision shows algorithmic rent-pricing antitrust exposure is not limited to RealPage, the vendor that has drawn the most attention in parallel multidistrict litigation; any owner or manager licensing software that pools non-public competitor data to generate pricing recommendations faces the same basic theory. The earlier per se finding, if it holds, would meaningfully lower plaintiffs' burden compared with a traditional rule-of-reason antitrust claim.

Filed
A tenant sued Willow Bridge and RealPage under Philadelphia's algorithmic rent-fixing ban over rents at Vue 32 and Rittenhouse Row; related suits target Bozzuto and Greystar.
The first court tests of Philadelphia's algorithmic rent-fixing ban: tenant Yiyao Liu sued Willow Bridge Property Company and RealPage on July 6, alleging Willow Bridge used RealPage's revenue-management software to set rents at Vue 32 and Rittenhouse Row using non-public competitor pricing data. Two related suits filed the week before target Bozzuto Management (with RealPage and Yardi) and Greystar Management Services (with RealPage and Yardi) over similar conduct.
Putative class action; three related suits filed
Why it matters: Liability theory attaches to the pricing-software platform itself, not just individual assets or landlords, exposing any multifamily owner or manager that licenses algorithmic revenue-management tools. Philadelphia's 2024 ordinance is among a growing wave of local and state algorithmic-pricing bans (New Jersey enacted one the same month), so owners operating across jurisdictions should audit vendor contracts and data-sharing practices now rather than wait for a ruling.
