This bill proposes to amend the 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 in the state to use algorithmic price fixing to establish rental rates. The bill establishes a rebuttable presumption of antitrust violations if the Attorney General can demonstrate that a person used algorithmic pricing with nonpublic competitor data, set or recommended rental rates, and that at least two competitors employed the same pricing algorithm in related markets.

Additionally, the bill outlines that the presumption can be rebutted if the defendant can provide clear evidence that they did not develop or distribute the algorithm and were unaware of its use of nonpublic competitor data. The Attorney General is designated as the enforcer of this section. Definitions for key terms such as "algorithmic pricing," "nonpublic competitor data," and "nonpublic data" are also included to clarify the scope of the law. Overall, the bill aims to enhance regulatory oversight of pricing practices in the rental market to prevent anti-competitive behavior.
