The 2025 legislative cycle marked a pivotal year in US privacy law, defined not only by continued nationwide expansion into Artificial Intelligence (AI) governance, children’s and teen privacy and online safety, as well as emerging data categories, but by a major restructuring of California’s privacy enforcement infrastructure. California’s introduction of the Delete Request and Opt-out Platform (DROP) system, the nation’s first centralized, statewide platform for managing consumer deletion requests; combined with sweeping reforms to the Consumer Privacy Fund, will materially increase CalPrivacy and attorney general enforcement capacity on a recurring, self-replenishing basis. These developments accompany completion of a far-reaching rulemaking package that imposes detailed obligations for Data Protection Impact Assessments (DPIAs or risk assessments), cybersecurity governance and Automated Decision-Making Technology (ADMT). At the same time, states beyond California have enacted targeted statutory reforms addressing neurotechnology, data-broker practices and minors’ online safety, underscoring that – absent federal preemption – state-driven models will continue to shape the national privacy compliance landscape in 2026. By January 2026, there will be 20 state consumer privacy laws in effect, several with unique material obligations. We detail what enterprises need to be prepared for in 2026 and explain why we believe next year will be a watershed period for consumer privacy in the US.
