Grocers matching store prices on Instacart grew 10 points faster, Instacart says

The list matters less than the number Instacart put next to it. Its internal retailer and customer data through the second quarter of 2026 shows retailers offering no-markup pricing grew 10 percentage points faster than those charging a markup. They also kept customers better.

So Instacart is pitching price parity to grocers as a growth decision, and it's bringing its own numbers to make the case.

A banner, a tab and a filtered view

Participating grocers get a yellow banner in the Instacart app and a place in a dedicated "no markups" tab, which exists to help shoppers find them. Instacart says more than 90% of Americans can now reach at least one grocery-parity retailer on its marketplace.

For a regional chain selling on the same app as much larger banners, a spot in a filtered view could count for as much as the price cut itself. That's the trade a digital commerce lead is weighing: margin on each marketplace item against visibility plus the growth Instacart says goes with it.

Shelf price versus the receipt

Those separate charges haven't gone anywhere. Service fees still apply on Instacart orders.

In practice, parity makes the simplest comparison a shopper can run, the app price against the shelf tag, come out even. Convenience costs stay on their own line. Jim Porterfield, Grocery Outlet's chief marketing officer, described the move as carrying the chain's in-store value to customers who split their shopping between the aisles and home delivery.

Parity arrives after loyalty and flyers

Price is the latest piece Instacart has added to its savings pitch. Digital flyers carry deals into the shopping flow.

What the 10-point gap can and can't show

The growth figure compares two groups of retailers that made different pricing choices, and the numbers come from Instacart's own data. They don't show whether parity caused the faster growth or whether grocers that already put value first, as Grocery Outlet says it does, were simply more likely to adopt it. Both could be true at once.

For a digital team deciding whether to switch, that makes the useful question narrower: how did retailers with similar baskets and similar online sales perform before and after they dropped the markup? Instacart pointed to stronger retention alongside the growth figure but didn't put a number on it, and retention is the measure that would show whether parity shoppers stick around.

Instacart named these five as "among" this year's adopters, so the tab already holds more grocers than the announcement lists. The signal to watch is whether Instacart publishes the comparison again for a later quarter. If the gap holds as more grocers join the tab, it gets harder to explain away as a matter of who signed up first.
