Instacart says it's ending its controversial system of using AI price tests for retailers. Earlier this month, an investigation by Consumer Reports and progressive think tank Groundwork Collaborative found that Instacart's algorithmic pricing charged various prices for the same item from the same store.

Instacart has announced it will end its AI-driven price testing system, which set different prices for the same grocery items for different customers. This decision follows reports from Consumer Reports and Groundwork Collaborative highlighting price differences of up to 7% for identical items, potentially costing families significantly more each year.

The move comes amid increased consumer distrust and a federal investigation by the FTC into the company's pricing practices. Instacart clarified that stores will continue to set their own prices on the platform, which may still differ from in-person prices.

Instacart ending AI price tests for retailers

This morning we have an update on a controversial new way of pricing groceries at Instacart. The system relies on artificial intelligence. The company has now changed its mind on using that technology. Jolene Kent has been following this story and has the latest. Instacart is pulling the plug on AI setting different prices for different customers. Earlier this month, Consumer Reports and progressive think tank Groundwork Collaborative found that Instacart's algorithmic pricing charged various prices for the same item from the same store. The prices varied by 7 percent on average, depending on the shopper, which could cost a family of four $1,200 more per year. One example, according to the report, a dozen eggs added to virtual carts at the same time from one Washington, D.C. grocery store rang up at five different prices, ranging from $3.99 to $4.79. Now just two weeks later, the online grocery platform says they fell short of customers' expectations, announcing in a blog post, effective immediately, Instacart is ending all-item price tests on our platform. Phil Lempert is a food industry analyst. The fact that they caved so quickly says to me that they know that they were doing something wrong. What does this say about what the consumer can trust or shouldn't trust when they're grocery shopping? Well, consumers have been very leery about AI to begin with. Now with this revelation about Instacart, consumers aren't gonna trust them. And what we're hearing more than anything else is don't screw around with our food. Instacart insists that this price testing was not dynamic pricing and that stores will continue to set their own prices on Instacart, on the platform, and they may very much differ from those in-person prices when you're hitting the store yourself. And Reuters also reported last week that the FTC is now probing Instacart over these controversial practices. Adriana? Yeah, Jo, especially at a time where people are trying to stretch their grocery budgets. Exactly. Thank you.
