Lawmakers in Seven States and Washington Want to Ban Electronic Shelf Labels in Grocery Stores. Walmart Just Ordered Them for All 4,600 Locations.

A collision is coming between retailers racing to digitize their price tags and a bipartisan legislative push that sees the same technology as a tool for algorithmic price discrimination. The stakes are billions of dollars in grocery spending.

Walmart is in the middle of deploying electronic shelf labels across every one of its 4,600 U.S. stores by the end of 2026 — roughly 2,300 locations already have them installed, CNBC reported last week. At the same time, legislators at both the federal and state level are moving to ban the technology outright in grocery stores. As we covered in our earlier analysis of digital shelf labels and dynamic pricing concerns, this technology sits at the intersection of operational efficiency and consumer trust. The legislative push has now escalated considerably.

The Federal Bill

Democratic Senators Ben Ray Luján and Jeff Merkley introduced the Stop Price Gouging in Grocery Stores Act of 2026, which would prohibit electronic shelf labels in large grocery stores and require stores to disclose their use of facial recognition technology. Senator Luján framed the issue in direct terms: "Our friends, family, and neighbors should be able to shop at their local grocery store without worrying about predatory pricing."

The bill was modeled on a 2025 House proposal and targets what sponsors call "surveillance pricing" — the practice of using algorithms to adjust prices based on data points like a shopper's purchase history, location, demographics, or even time of day. The concern isn't hypothetical: Instacart discontinued its AI-powered pricing initiatives in 2025 after a study revealed price disparities of up to 23% for identical products.

Seven States Are Moving Too

The federal bill isn't happening in isolation. New York Attorney General Letitia James called for passage of two companion bills: the Protecting Consumers and Jobs from Discriminatory Pricing Act, which would ban ESLs in grocery stores and pharmacies entirely, and the One Fair Price Act, which would ban surveillance pricing statewide and prohibit using personal data to set individualized prices.

AG James cited research showing that 74% of grocery items were offered at multiple prices simultaneously, with some items carrying up to five different price points. "When New Yorkers place an order online or go to the grocery store, they should be able to trust that they are seeing the same prices as everyone else," she said. Oklahoma, Washington, Arizona, Nebraska, Maryland, and Tennessee have all introduced their own surveillance pricing or ESL legislation. Tennessee's bill is particularly aggressive — it would ban ESLs and any digital shelf display technology in food retail establishments over 15,000 square feet, and would separately prohibit personalized algorithmic pricing.

The Retailer Argument

Walmart and other ESL proponents insist the technology is about operational efficiency, not dynamic pricing. The company has repeatedly stated that its digital shelf labels are not designed for surge pricing and that prices remain the same for every customer in every store. The efficiency gains are real: ESLs eliminate the labor-intensive process of printing and placing paper price tags, reduce pricing errors, and enable faster markdown execution.

Kroger, Amazon Fresh (before its recent closures), and European grocers like Carrefour and Albert Heijn have also deployed ESLs at scale, largely without the pricing discrimination concerns that have animated U.S. legislators.

The problem for retailers is that the technology's capability matters as much as its current use. Electronic shelf labels can technically change prices in real time — that's the engineering reality. The fact that Walmart says it won't use them for surge pricing today doesn't prevent it, or any other retailer, from doing so tomorrow. And legislators are writing laws based on capabilities, not promises.

What Happens Next

The legislative momentum is real, but passage is far from certain. The federal bill faces an uphill path in a divided Congress, and state-level bills vary widely in scope and political support. The grocery industry will lobby aggressively against outright bans, arguing that the legislation conflates the price display technology with the pricing practices it could theoretically enable.

But the political optics are challenging for retailers. In a consumer environment where 46% of shoppers cite high prices as a financial strain — a number that's been above 40% for seven consecutive months — any technology that even looks like it could be used to charge different people different prices for the same gallon of milk is going to draw fire. The collision between retail's digitization agenda and the public's pricing anxiety is only going to intensify through 2026.
