New York’s Algorithmic Pricing Disclosure Act is now in effect (as of November 10, 2025). (Read our coverage of the law in our June 25, 2025 Advertising Law Blog post.) Originally enacted in May as part of the state’s 2025-2026 omnibus budget bill, the law's effective date was delayed due to a failed legal challenge in the United States District Court for the Southern District of New York by the National Retail Federation, who alleged that the Act’s mandatory disclosure requirement violated the First Amendment and sought a preliminary injunction.
