rental price fixing; algorithmic pricing

HB 2847 prohibits landlords and rental platforms from using algorithmic pricing that relies on hidden competitor data to set residential rental rates. It creates a legal presumption of antitrust violations if the attorney general proves three conditions: (1) the algorithm used nonpublic competitor data, (2) it set residential rental rates, and (3) multiple competitors used the same algorithm in the same market. The bill defines "algorithmic pricing" broadly to include AI/machine learning systems and "nonpublic competitor data" as hidden information from competitors - not public reports or industry surveys. Landlords can challenge the presumption by proving they didn’t develop the algorithm or know it contained hidden competitor data. This targets practices where rental platforms collude via shared algorithms, directly affecting rental businesses using such technology.
