OH SB79

Prohibits any person from using or distributing a pricing algorithm that uses, incorporates, or is trained with nonpublic competitor data, treating such use as a conspiracy against trade under Ohio antitrust law

Creates a legal presumption that a defendant entered into an anticompetitive agreement if they distributed a pricing algorithm to two or more competitors in the same market, or if they used one that another competitor also used to set prices

Requires businesses with $5 million or more in annual gross receipts to disclose to customers before purchase, and to employees/contractors, when a pricing algorithm sets or recommends prices or commercial terms

Mandates disclosures must include whether the algorithm sets different prices for different customers seeking identical products, and must identify who developed or distributed the algorithm

Classifies violations of the disclosure requirements as unfair or deceptive trade practices, and expands Attorney General investigative authority to obtain information on pricing algorithm development and distribution
