Based on a TikTok video, a message on the social network X claims that Walmart supermarkets in the United States are adjusting prices in real-time thanks to AI.
- Sources say digital labels would be widespread in the aisles, with amounts fluctuating throughout the day.
- While the chain has updated its labeling system, it does not currently use AI-driven dynamic pricing.
For a few years, consumers have been accustomed to dynamic pricing systems, such as in the transportation sector. A train or plane ticket’s price online could increase or decrease based on demand, time of year, or fuel costs.
Could this practice extend to supermarkets? A video on X suggests so: according to the account sharing it, the American retail giant Walmart – with over 4,500 stores across the U.S. – is now using AI to adjust product prices. “Digital prices can change within seconds while you shop,” we are assured.
Fixed prices without recourse to AI
In the original video, easily traceable on TikTok, a man’s voice claims to have seen a digital label price change suddenly, upwards. The clip dates back several months, as the influencer with 850,000 subscribers uploaded it in mid-October 2025.
Is this evidence of Walmart adopting dynamic pricing with AI technology? To verify, one can review several articles in the American press. Last year, CNBC mentioned an initiative by the retail giant: by the end of 2026, all stores would be equipped with “digital price display labels”. A nationwide rollout in the U.S.
However, there was no mention of adjusting product prices in real-time or using AI for remote management. A team leader, interviewed by the network, presented this initiative as a time-saving tool. Previously, paper labels required human intervention whenever a product’s selling price fluctuated. The store now says it is possible to harmonize prices and ensure consistency nationwide.
Another advantage highlighted in the press is the improved readability of these digital labels. A noticeable evolution for customers, but especially for delivery drivers who sprint through aisles to gather products ordered online by consumers. The use of “blinking icons” is popular for easier identification of different references on shelves.
Uproar across the United States
If a company like Walmart introduces these new labelings, it is not alone across the Atlantic in making such a transition. Kroger, another retail giant, has also opted for a digital system. These decisions have left some consumers skeptical, fearing misuse of these technologies to the detriment of customers.
In New Jersey, “legislators are taking steps to ban retailers […] from using dynamic pricing tactics and surveillance, relying on consumer data to personalize prices,” reports the American edition of The Sun this week. Legislators are concerned about potential abuses and how major retailers might quietly implement real-time pricing modification systems, tailoring them to each customer.
