DoorDash Is Paying $17 Billion for Instacart. The Real Target Is Amazon and Walmart's Grocery Lead

A company at its best gets sold

Here's the odd part. On the same day Instacart reported what CEO Chris Rogers called its best quarter as a public company, DoorDash said it plans to buy it in a deal valued at $17 billion.

There are two ways to read that. The generous one is that Instacart is selling at a high point and getting the best price it can. The less flattering one is that even a best-ever quarter doesn't change who it's up against: Amazon and Walmart, whose grocery operations are far larger. The sources frame the deal as a way to keep Instacart from getting "crowded out of the aisle." That's the core story. This isn't a victory lap. It's a bet that two delivery apps together can hold ground that neither could hold as well on its own.

DoorDash says groceries are "one of the hardest things to get right online." It plans to spend $17 billion trying anyway.

What happened

DoorDash released its earnings a week early, likely because the deal was already leaking. Last week, Instacart was reportedly talking to both DoorDash and Uber. Reports this week said it had dropped Uber and was focusing on DoorDash. This would be DoorDash's largest deal yet, even after a buying spree that included Deliveroo and SevenRooms.

DoorDash's core business is strong. Gross order value grew 36% year over year in Q3 to nearly $34 billion, a hair above analyst estimates. That's the total dollar value of everything people ordered through the app. Orders jumped 28% to 993 million. It already has grocery partnerships with Kroger and Costco, yet it admits groceries are "one of the hardest things to get right online." Anyone who has ordered peach yogurt and received pumpkin-spice cream cheese knows what it means.

One gap: our sources don't give Maplebear's share price before the news. So we can't tell you the premium, meaning how far $17 billion sits above what the market was paying. If you own the stock, that's the first number to look up. It tells you how much upside is already priced in and how much you're giving up by waiting for a deal that may not close until 2027.

Why it matters: scale is the whole game

Both sides are playing defense. Amazon has shifted its focus from the in-store Whole Foods experience toward selling more pantry staples online with very fast delivery slots. Walmart has expanded its under-30-minute delivery service, which has helped drive its e-commerce growth. Instacart is a much smaller player facing two giants that are speeding up.

DoorDash wants to move beyond burritos and sushi into everyday staples. Restaurant delivery is a treat that people cut first when money gets tight. Groceries are a habit, and that kind of spending tends to hold up in a downturn. The bet is that owning both makes DoorDash's business steadier. Whether the combination actually saves money or justifies $17 billion is something the sources don't put numbers on. Until DoorDash shows figures in a filing, treat any big promises about savings with skepticism.

There's also a slow tailwind. Most Americans still prefer to pick their own avocados, but a growing share order groceries online at least occasionally. As the population ages, more people may come to depend on delivery. DoorDash is paying now for a market it expects to keep growing.

The bigger picture: regulators, and a rough patch even for Amazon

The expected close of at least the end of 2027 is long, and that timeline may already account for antitrust scrutiny. The FTC could be especially wary here because groceries are a necessity and cost of living is a top concern at the agency. DoorDash is also one of a handful of companies the FTC said this week it is studying over algorithmic pricing, meaning software that sets prices automatically. For Maplebear shareholders, the practical effect is a long wait with real risk the deal changes or falls apart. You're betting on regulators as much as on groceries.

Amazon's latest quarter shows how hard this market is right now. Online stores revenue was $68.5 billion. That was up just 2% year over year and below the roughly 5% growth analysts expected. Ad revenue growth slowed to 11% from 26% the quarter before. Some of that is timing, since Amazon moved Prime Day into Q2 in many markets, so don't read it as a collapse. But part of the slowdown may come from AI shopping agents like Meta's Muse, which Amazon has barred from its store. Shares fell as much as 7% after hours.

The takeaway for anyone in this sector: the biggest player is fighting for every point of growth, and new competitors like AI shopping agents are entering the field. That helps explain why Instacart wanted a bigger partner. What to watch next: the actual premium Maplebear holders receive, how the FTC frames its first questions, and whether Amazon's online sales recover next quarter once the Prime Day timing is no longer distorting the comparison.
