This bill proposes to amend Arizona Revised Statutes by adding a new article that specifically addresses algorithmic price fixing in the context of residential rental rates. Under the new law, it would be prohibited for individuals to use algorithmic price fixing to establish rental rates. The bill establishes a rebuttable presumption of antitrust violations if certain conditions are met, such as the use of nonpublic competitor data in algorithmic pricing by at least two competitors in related markets.

Additionally, the bill outlines the responsibilities of the attorney general in enforcing these provisions and provides definitions for key terms such as "algorithmic pricing" and "nonpublic competitor data." The definitions clarify that algorithmic pricing includes processes derived from machine learning or artificial intelligence and that nonpublic competitor data refers to information not widely available to the public, specifically in the context of competition in the same or related markets. Overall, the bill aims to enhance regulatory oversight of pricing practices in the rental market to prevent anti-competitive behavior.
