Maryland Becomes First US State to Ban AI-Driven Grocery Pricing — Critics Say the Law Has Carveouts
Maryland enacted the first US state-level ban on AI-driven surveillance pricing in grocery stores, signing the bill into law on May 1. The law prohibits retailers from using personal consumer data to dynamically adjust product prices in real time — the model increasingly piloted by large grocery chains using electronic shelf labels and purchase-history analytics.
What the Law Does
The Maryland measure bars grocery stores from feeding individual consumer data into pricing algorithms that change the sticker price for a specific shopper — or raise it based on inferred willingness to pay. The core target is the practice of using loyalty card data, location, browsing history, and purchase patterns to present different prices to different customers for identical goods.
Maryland’s law is specifically scoped to grocery stores and food retail. It does not cover e-commerce, fuel, or other retail categories.
What It Does Not Do
Consumer advocates immediately flagged the carveouts. The Guardian’s reporting notes the law is “full of carveouts” — the specific exemptions were not fully detailed in published accounts, but the pattern in similar consumer data legislation is to exclude aggregate pricing optimization (changing prices for all customers based on demand, not personal profiles), loyalty discount programmes, and coupon-based personalization.
That distinction matters: dynamic pricing based on real-time demand — the model used by airlines, hotels, and Uber — is not the same as surveillance pricing based on individual profiles. Maryland’s law appears to target the latter while leaving the former untouched.
Why It Is Moving at the State Level
Federal action on AI pricing has stalled. The FTC opened an inquiry into surveillance pricing in July 2024 that produced no enforcement action. With the White House AI legislative framework pushing federal preemption of state rules across other AI categories, Maryland moved on consumer protection — an area where states have traditionally had clearer authority — before that window potentially closes.
The New York RAISE Act, finalized separately, covers general AI risk and incident reporting. Maryland’s law is narrower and more immediate: it applies now and is directly enforceable against any grocery retailer operating in the state.
The Industry Context
AI-powered dynamic pricing in physical retail has accelerated since Kroger’s failed Albertsons merger put its proprietary pricing data and ESL rollout back in the spotlight in 2024. A Bernstein analysis in early 2026 estimated 15-20% of US grocery chains were piloting some form of demand-responsive pricing on physical shelf tags. Maryland’s law would put any of those deployments operating in the state under immediate legal risk if they incorporate individual consumer profiles.
Whether other states follow depends on whether Maryland’s law survives expected industry legal challenges. Walmart and Kroger both have significant Maryland footprints.
