Why It Matters
Across the United States, consumers may be paying different prices for the same grocery items — not because of sales or loyalty discounts, but because of artificial intelligence algorithms that use personal data to determine how much each individual shopper will pay. The practice, known as surveillance pricing, has drawn growing concern from consumer advocates and state lawmakers who say the technology threatens both personal privacy and household affordability.
With grocery costs already straining family budgets nationwide, the push to regulate algorithmic and surveillance pricing has moved from federal watchdog reports to active state legislative chambers, making it one of the more urgent consumer protection debates of 2026.
What Happened
A September 2025 investigation in Seattle by Consumer Reports and Groundwork Collaborative found that Instacart, a major online grocery delivery platform, was using an AI-powered pricing algorithm that charged different customers different amounts for the same products — at the same store, at the same time. In one documented case, one shopper was charged $3.99 for a box of Wheat Thins while another paid $4.89 for the identical product.
The price gap represented a difference of as much as 23%, depending on the item. Instacart has since discontinued offering the technology to grocery retailers, but the investigation triggered a broader national conversation about how algorithmic tools are being used across retail markets.
In response, lawmakers in several states have introduced legislation aimed at either requiring companies to disclose when personal data is used to set prices, or outright banning surveillance pricing practices. Oklahoma Democratic state Representative Cyndi Munson introduced one such bill, which would regulate how food retailers use algorithmic pricing and prohibit surveillance pricing altogether.
“I don’t have control over the price of bread or eggs or milk,” Munson said. “But we do have some say on how corporations are going to operate in our state.”
By the Numbers
- 23% — The maximum price difference detected between customers buying the same item from the same Instacart-powered store at the same time.
- $0.90 — The dollar difference between the lowest and highest price found for a single box of Wheat Thins in the Seattle investigation ($3.99 vs. $4.89).
- September 2025 — The month Consumer Reports and Groundwork Collaborative published findings from the Instacart pricing investigation.
- Several states — The number of state legislatures currently considering bills targeting surveillance pricing or algorithmic pricing disclosure requirements, with Oklahoma among the most prominent examples.
- Years — The length of time businesses have used broader algorithmic pricing tools, though the use of personal data to set individualized prices represents a newer and more targeted evolution of the practice.
Zoom Out
Surveillance pricing in groceries is part of a wider trend of algorithm-driven pricing that has drawn regulatory scrutiny across multiple industries. In the housing market, cities and some states have already moved to ban or restrict the use of algorithmic tools that landlords use to coordinate rent increases — a practice critics say has contributed to rising housing costs in urban areas.
The Federal Trade Commission released a report in 2024 examining surveillance pricing practices across eight major retail-adjacent firms, flagging the potential for discriminatory pricing based on demographics inferred from personal data. That report laid the groundwork for the current wave of state-level legislative action.
Businesses have long used automated pricing systems to adjust costs based on supply and demand, competitor pricing, and market conditions. The newer concern centers specifically on the use of individual consumer data — including browsing habits, purchase history, location, and device type — to predict the maximum price a specific person will pay, effectively creating a personalized price ceiling for each shopper.
Consumer advocates warn that such systems could disproportionately harm lower-income shoppers or those with less access to price comparison tools, widening existing economic disparities in the retail marketplace.
What’s Next
Oklahoma’s proposed legislation is among the most direct state-level attempts to restrict surveillance pricing in the food retail sector. If passed, it would establish new requirements for how grocery retailers may use algorithmic systems and bar the use of personal data to set individualized consumer prices.
Lawmakers in additional states are expected to advance similar bills through committee hearings in coming months. Consumer advocacy groups are monitoring those efforts and pushing for federal action as well, arguing that a patchwork of state laws could create compliance challenges without delivering uniform protections for American shoppers.
For now, the legislative momentum signals that surveillance pricing — once a largely invisible retail practice — has become a high-profile policy target heading into the second half of 2026.
