Part One: The Shelf — A Price That Can Change in Seconds

Kroger began testing electronic shelf labels in 2018, expanded to roughly 500 stores by 2023, and has since scaled sharply. The company confirmed that nearly one in four of its stores now use the technology; in its Cincinnati home market, reporting indicates 103 of 104 stores already have it. The labels sit in white plastic frames that closely resemble the printed tags they replace, so most shoppers may not notice the change.

Functionally, ESLs replace the manual task of swapping paper tags with a wireless network of displays that can be updated from a single console. Industry groups estimate a typical store changes well over 7,000 tags a week. The Food Industry Association reported that about 24% of food retailers it surveyed were already using ESLs, with another 29% planning to. The global market for the devices was valued near $1.85 billion in 2024 and is projected by Grand View Research to exceed $7.5 billion by 2033.

The same instant-update capability that saves labor is what makes the technology consequential. A price is no longer fixed for the day; it can move. On its own, that enables broad “surge pricing” — raising the cost of bread or bottled water ahead of a storm. The more contested question is whether that price could be tailored not just to conditions, but to the individual shopper.

Part Two: The Data Engine — What Kroger Knows

Kroger is not only a grocer; it is a major data company. Its analytics subsidiary, 84.51°, powers Kroger Precision Marketing (KPM), the company’s retail-media arm, which sells advertising and insights to roughly 2,000 brands, including Procter & Gamble, Nestlé and General Mills. The business is built on the loyalty program: Kroger has said that around 96% of its sales are tied to a loyalty identity, giving it purchase data spanning roughly 60 million households.

That data business is highly profitable and growing. According to estimates from Guggenheim Securities cited by Consumer Reports, Kroger’s precision-marketing operation earned roughly $450 million in profit in 2023 and $527 million in 2024, with projections approaching $825 million by 2027. A 2025 Consumer Reports investigation reported that 84.51° marketing materials referenced detailed shopper segments — including an “ethnic panel” of Hispanic shoppers — and described a “persistent household identifier” capable of being traced back to an individual consumer.

In simple terms: Every time a shopper scans a loyalty card or uses the app, Kroger records what was bought. Over years, that builds a detailed profile of a household — the same kind of profile that, in theory, could be used to decide what price or offer that household sees.

This first-party data can also be combined with information purchased from outside data brokers, a practice the FTC has documented across the retail sector. The result is an infrastructure designed to infer who a shopper is, what they want, and how they behave — capabilities originally built to target advertising, but which regulators note can also be used to target prices.

Where the Two Systems Meet

The pricing mechanism and the data engine become significant when joined. Critics describe this convergence in three layers, moving from documented capability to prospective risk.

1. The smart shelf: EDGE and the Microsoft partnership

Kroger has developed a system it calls the Enhanced Display for Grocery Environment (EDGE) Shelf, built in part through a partnership with Microsoft. EDGE combines digital price displays with screens capable of showing advertising. In an August 2024 oversight letter, Senators Elizabeth Warren and Bob Casey wrote that the system was designed to place cameras at displays and use facial recognition to estimate a shopper’s age and gender in order to push personalized offers. Representative Rashida Tlaib raised parallel concerns, citing well-documented racial bias in facial-recognition technology.

Kroger has firmly denied deploying facial recognition in connection with pricing. The company told multiple outlets it is not using facial recognition for prices and that privacy is a key consideration in any new technology. The dispute therefore centers on capability and intent: the hardware and partnerships that make demographic inference possible exist, even as Kroger says it does not use them to set prices.

2. The dynamic-pricing layer

Separately, lawmakers noted that in early 2024 Kroger began working with Intelligence Node, a firm that markets AI-driven dynamic-pricing and market-analytics tools. Combined with ESLs that can change a displayed price in seconds, a dynamic-pricing engine supplies the logic for what that price should be at any given moment. Kroger frames such tools as a way to reflect supply, demand and perishability — for example, marking down items nearing their sell-by date, which research from UC San Diego cited in coverage suggests could cut food waste by roughly 21%.

3. The personalization layer — “maximum willingness to pay”

The most contested scenario is the joining of all three: a shopper profile (from loyalty and app data), a way to recognize or segment that shopper in-aisle (EDGE, app geolocation, or demographic inference), and a screen that can instantly display a tailored number. Warren and Casey warned this could let Kroger build “personalized profiles” and display “the customer’s maximum willingness to pay” on the digital tag — a capability, they noted, that would be impossible with a paper label. Analysts have compared the prospect to airline-style pricing, where the same item carries different prices for different buyers.

In simple terms: The worry is not one gadget. It is that the loyalty profile (who you are), the smart shelf (recognizing you), and the digital tag (changing the price instantly) could line up so the price you see is calculated for you specifically — set at the most you are likely to pay.

What Federal Regulators Have Found

The concern is not purely hypothetical across the retail sector. In July 2024 the Federal Trade Commission issued orders under Section 6(b) to eight intermediary firms — including Mastercard, Accenture, Revionics, PROS, Bloomreach and McKinsey & Co. — that build pricing and segmentation tools for retailers. In January 2025 the FTC released initial findings describing how a wide range of personal data, from a shopper’s precise location and demographics down to mouse movements and abandoned cart items, can be used to set individualized prices.

FTC staff offered a now widely cited hypothetical: a consumer profiled as a new parent could be shown higher-priced baby thermometers, with the seller inferring urgency from recent searches. Staff found the intermediaries studied worked with at least 250 clients spanning industries from grocery to apparel. A separate investigation into Instacart cited by privacy group EPIC found price variations of up to 23% between customers for identical items — a difference that could amount to roughly $1,200 a year for some shoppers.

The FTC study names third-party intermediaries rather than Kroger specifically, and it documents capability rather than asserting wrongdoing. But it establishes that the underlying practice — using personal data to set individualized prices — is operational in U.S. retail, which is precisely why a grocer pairing rich household data with instant-update shelves has drawn scrutiny.

The Legislative and Regulatory Response

Policymakers have moved on both the pricing hardware and the data practices. At the federal level, the Stop Price Gouging in Grocery Stores Act of 2026 (S. 3892), introduced in February 2026 by Senators Ben Ray Luján and Jeff Merkley, with a House companion (H.R. 4966) led by Rep. Rashida Tlaib and Rep. Val Hoyle, would prohibit “surveillance-based price setting,” require disclosure of facial-recognition use, and ban electronic shelf labels in food stores larger than 10,000 square feet — enforced by the FTC. The measure is backed by the United Food and Commercial Workers (UFCW) union, which represents more than 800,000 grocery workers.

States have moved faster, and several target the data side directly:

New York’s Algorithmic Pricing Disclosure Act, effective July 8, 2025, requires businesses using personalized pricing to post a disclosure stating, in substance, that a price was set by an algorithm using the shopper’s personal data, and bars the use of protected-class data.
Maryland enacted limits on dynamic and data-based pricing for certain food items in larger stores, enforced by the state attorney general.
According to the UFCW, at least a dozen states — including New York, New Jersey, Illinois, Georgia, Arizona, Maryland, Minnesota, Nebraska, Tennessee, Washington, Iowa and Oklahoma — have introduced bills restricting digital pricing technology at large grocers.

Oversight is also continuing. On March 5, 2026, the chairman of the House Committee on Oversight and Government Reform launched an inquiry into AI-based surveillance pricing, sending letters to consumer-facing companies and noting that personal data can be used to estimate a consumer’s “emotional state, purchase intent, [and] maximum willingness to pay.” The National Retail Federation has separately challenged New York’s disclosure law on First Amendment grounds, signaling that the legal questions remain unsettled.

Kroger’s Position

Kroger has consistently rejected the surveillance-pricing framing. In response to congressional inquiries, the company stated it “does not and has never engaged in surge pricing,” and that any test of digital tags is meant to lower prices where it matters most. It says its model depends on attracting more shoppers through lower prices, not extracting higher margins, and that ESLs primarily reduce labor, cut pricing errors and limit food waste.

On data, Kroger and 84.51° describe a “trust-value” relationship with customers and emphasize compliance with privacy laws and opt-out rights. The company has specifically denied using facial recognition in connection with pricing. Its new chief executive, Greg Foran, who took the role in February 2026, has made affordability central to his agenda, telling Bloomberg he intends to cut prices on thousands of products. In Kroger’s account, its data and pricing tools are efficiency and personalization features that benefit shoppers, not mechanisms to extract their maximum payment.

What It Means for Consumers

For shoppers today, the visible change is small: a digital number where a paper tag used to be, and personalized coupons through the app. The significance lies in what the combined infrastructure makes possible, and in how little visibility consumers have into it.

Price opacity. If prices can change through the day, a remembered or shelf-displayed price may differ at checkout, making comparison harder.
Personalized offers vs. personalized prices. Targeted discounts are already routine; the contested line is whether the base price a shopper sees could be shaped by their profile.
Discrimination risk. Even without using protected traits directly, profiles built on location and purchase history can act as proxies for race, income or other characteristics — a concern the FTC and lawmakers have repeatedly flagged.
Consent and awareness. Consumer Reports surveys found roughly 76% of Americans oppose loyalty discounts based on demographics and about 72% oppose them based on online behavior, indicating a wide gap between industry practice and public comfort.

It is important to state plainly that the most extreme scenario — individualized prices on the shelf tied to a shopper’s profile — is largely prospective at Kroger and is denied by the company, not a documented practice. The debate is, in significant part, about whether to regulate a capability before it is used, given how completely the necessary pieces are now assembled.

Analysis

The Kroger story is best understood as a question of architecture rather than any single product. Electronic shelf labels supply the output device — a price that can change instantly. The loyalty program and 84.51° supply the input — a detailed, household-level picture of who is shopping. EDGE, the Microsoft partnership and AI pricing partners supply the connective tissue that could, in principle, link the two. Each component is independently lawful and commonly defended on efficiency grounds. It is their integration that creates the capability lawmakers are trying to pre-empt.

Both sides argue from accurate facts. Kroger is correct that digital tags are mature, globally common, and not shown to be setting individualized in-store prices; it is also correct that the same tools can be used to cut prices and waste. Critics are correct that the supporting data infrastructure is real, profitable and expanding, and that the FTC has documented surveillance pricing operating elsewhere in retail. The disagreement is less about today’s facts than about the trajectory and the guardrails.

The likely near-term outcome is a regulatory patchwork. Federal legislation faces an uncertain path, while states move at different speeds and with different targets — some banning the hardware, others mandating disclosure of the data practice. For a multi-banner operator like Kroger, that fragmentation may shape where and how aggressively the combined system is deployed, and whether the line between personalized offers and personalized prices is drawn by regulators or by the company itself.

Conclusion

Kroger’s digital pricing and its data surveillance programs are converging components of one modern retail system: instant, centralized, data-aware pricing arriving in mainstream grocery faster than the laws meant to govern it. The technology is neither inherently abusive nor inherently benign; its meaning depends on how it is connected and constrained. Whether the shelf ever truly “knows your name” — and prices accordingly — will be decided less by what the hardware can do than by the rules written in Washington and the statehouses, and by how much transparency consumers are ultimately given into the number in front of them.

Key Takeaways

Kroger’s electronic shelf labels (now in ~1 in 4 stores) and its data business (84.51° / Kroger Precision Marketing) are two halves of one capability: instant price changes plus detailed shopper profiles.
Roughly 96% of Kroger sales are loyalty-linked, giving it data on ~60 million households; its precision-marketing arm earned an estimated $527 million in 2024, with profits projected to approach $825 million by 2027.
The EDGE Shelf, built with Microsoft, gave rise to lawmaker concerns about cameras, facial recognition and displaying a shopper’s “maximum willingness to pay” — capabilities Kroger says it does not use for pricing.
The FTC’s 2025 surveillance-pricing findings documented retailers using personal data — location, demographics, even mouse movements — to set individualized prices, establishing the practice exists across retail.
Federal (S. 3892 / H.R. 4966) and state laws (New York’s Algorithmic Pricing Disclosure Act, Maryland, and a dozen others) target ESLs, surveillance pricing, or both; a House Oversight inquiry opened in March 2026.
The most extreme scenario — individualized shelf prices tied to a personal profile — remains largely prospective at Kroger and is denied by the company; the policy fight is over regulating the assembled capability before it is used.
