Maryland’s Surveillance Pricing Ban Is Narrower Than the Headlines. The Supplier Implications Are Too.

Maryland Governor Wes Moore on April 28 signed the Protection From Predatory Pricing Act, House Bill 895, making Maryland the first state to enact a direct ban on personalized pricing in grocery. The law takes effect October 1, 2026, and carries civil penalties of up to $10,000 for a first violation and up to $25,000 for subsequent violations, with enforcement reserved to the Maryland Attorney General.

The headline version of this news has been straightforward: Maryland banned surveillance pricing, fines start at $10,000, other states are watching. The version that matters for Walmart suppliers is narrower than the headlines suggest.

What the Law Actually Covers

According to legal analyses published by Troutman Pepper Locke and the National Law Review, the law applies only to “food retailers” defined as merchants operating a business establishment of at least 15,000 square feet that sells food exempt from Maryland sales and use tax, and to third-party delivery services that arrange the delivery of such food. General merchandise retailers are not covered. Walmart Supercenters and Walmart Neighborhood Markets in Maryland fall under the food-retailer definition; a Marketplace seller shipping a non-grocery item to a Maryland consumer does not.

The law imposes three core restrictions, per the Troutman Pepper Locke analysis. Food retailers and third-party delivery services may not use dynamic pricing, defined in the statute as setting a personalized price for a consumer based on that consumer’s personal data. They may not use personal data to set higher prices for specific consumers. And they may not use the personal data of members of legally protected classes to deny or withhold a consumer benefit available to others.

Several exemptions narrow the scope further. The law covers only the use of personal data to set higher prices, with no baseline reference price established in the statute. Consumer Reports, which lobbied for the bill and issued a statement on the day of signing, said industry-driven exemptions weakened the final version and the law “won’t protect Marylanders from surveillance pricing” as enacted. Senior policy analyst Grace Gedye cited both the loyalty-program exemption and weak enforcement provisions, including a 45-day cure period before the Attorney General can pursue penalties.

Where Walmart Sits Relative to the Law

Walmart’s stated position on its digital shelf label rollout, on the record across multiple primary sources, is that the labels are not used for personalized pricing. In a March 2 corporate blog post, Walmart described its DSL system as closed-loop, non-interactive with shoppers, and not collecting any consumer information, and said prices remain consistent regardless of demand, time of day, or who is shopping. Walmart corporate communications director Robyn Babbitt told Bankrate the labels are intended to support associate productivity rather than to vary prices by shopper.

That positioning matters for compliance reading. The Maryland law restricts pricing practices that use personal data to set individualized prices; it does not restrict the digital shelf label hardware itself. Walmart’s stated practice on shelf pricing is consistent with the law’s core prohibitions. What the law adds is a binding legal floor under that stated practice in Maryland and a defined penalty for departing from it.

The Supplier Read Is Narrower Than the Headlines Suggest

The supplier-side implications fall into three categories.

For 1P suppliers, the most likely Maryland-specific change is in promotion mechanics that vary the price a specific consumer is charged based on personal data, not in advertising mechanics that vary which ads a specific consumer sees. Walmart Connect campaigns that use first-party data to surface targeted advertising are not the focus of the law’s restrictions on price-setting. The law restricts using personal data to charge different shoppers different prices for the same item, with loyalty-program pricing exempted. Supplier-funded basket-level discounts or app-delivered offers in Maryland grocery that rely on personal data outside the Walmart+ framework will need a Maryland review before October 1.

For 3P sellers, the direct exposure is narrower. The law applies to food retailers and third-party food delivery services. Marketplace sellers shipping general merchandise are not covered; sellers using Walmart Fulfillment Services for grocery items into Maryland should confirm with their account teams how Walmart is interpreting the third-party delivery provision for WFS-fulfilled grocery orders.

For both, the read across state lines is the more important question. Bloomberg Law reported in February that state lawmakers have introduced more than 70 bills targeting surveillance pricing across industries this year. The compliance lift on October 1 is bounded; the lift if a second and third state enact different versions is not. Suppliers should ask Walmart account teams whether Maryland-specific changes will apply nationally, in Maryland only, or hold pending the next state. The answer will indicate how Walmart is setting up to manage a multi-state patchwork the industry expects to grow.

The Maryland law is, as Consumer Reports put it on the day of signing, less than its advocates wanted. The more useful framing for suppliers is that it is more than symbolic: a binding legal floor on personalized grocery pricing in one state, with a defined effective date, and unlikely to be the last.
