As of 9 November 2026, the largest deal in grocery delivery is still a set of assumptions rather than a finished business. DoorDash agreed on 29 October to buy Instacart at USD 65 per share, an equity value of about USD 17 billion and a 26 percent premium to the 22 October close, with at least three quarters of the consideration in cash. The interesting part for a retailer or a brand is not the price but the four sources of value management has put in front of analysts.
What was actually announced
The scale is easy to understate. Instacart already lists close to 100,000 stores, and the companies say customers would gain access to more than 50,000 additional locations through the combination, while DashPass and Instacart+ members would reach both services on one membership with about USD 100 million of annual subscription savings. That is a consumer-facing promise, and it is also a claim about how many orders per member the combined platform expects to carry.
DoorDash brings the order volume. It reported 993 million orders in the third quarter, up 28 percent, though only 17 percent without Deliveroo, on marketplace gross order value of USD 33.9 billion and revenue of USD 4.6 billion. The company also says its own United States grocery gross order value is growing more than twice as fast as restaurants, which is the reason a restaurant-led marketplace is paying for a grocery catalogue.
The four sources of value, and what each one assumes
The first source is demand: restaurants on Instacart, and categories that today live on only one platform moving to both. The second is advertising, where consumer packaged goods advertisers get more shoppers to reach and, in the company's framing, more return on ad spend. Instacart's advertising and other revenue reached USD 331 million in the quarter, up 23 percent, so the base being scaled is already substantial.
Software and fulfilment are the quieter half
The third source is software, sold to grocers as first-party infrastructure that DoorDash can cross-sell to its own retail partners. The fourth is fulfilment, where the company argues its own warehouses are near perfect on accuracy while third-party stores sit in the low nineties, a gap that becomes a cost line once order volume doubles.
| Source of value | What it assumes | Evidence to check |
|---|---|---|
| Demand | Cross-listing lifts orders without new customers | Orders per active member after closing |
| Advertising | More shoppers convert into more ad spend | Advertising revenue growth against order growth |
| Software | Grocers buy one stack instead of two | Number of retailers on the combined platform |
| Fulfilment | Owned capacity is more accurate and cheaper | Order accuracy and cost per order by channel |
The competitive question is whether the combination changes the price a brand pays to be found. A platform that owns the delivery network, the retailer's online storefront and the advertising inventory sits in three places at once, and regulators tend to look closely at exactly that overlap, which is why the timetable is now set by approvals rather than by customers.
Why the calendar matters more than the synergy number
Closing is expected at the end of 2027 or in the first half of 2028, and requires Instacart stockholder approval, the end of the antitrust waiting period and clearances in Canada and Israel. Holders of 19 percent of Instacart have already agreed to vote in favour, which reduces one risk without removing the other, and until closing the two companies keep operating separately.
Market size claims deserve a discount
Deals of this kind arrive with category forecasts attached, and those forecasts are usually produced by the same houses that advise on the transaction. A marketplace number is a useful frame for consumer demand, but it is not a substitute for the two figures a retailer can check: orders per store per week and the ad revenue attached to each one.
What a retailer should verify before the deal closes
Until closing, the two platforms remain separate businesses, which gives retailers a narrow window to check the assumptions while they still have leverage. The five steps below are cheap to run now and expensive to run later, because after a change of control the contract terms are set by the new owner rather than negotiated.
FAQ
Does the deal change grocery prices for shoppers?
Not directly, because the two platforms keep competing until closing, but a combined advertising business can raise the cost of visibility for brands and that cost usually finds its way into shelf prices over time.
Why is the synergy figure set for year three?
Because the first two years are consumed by integration, contract renegotiation and the regulatory process, so the number is a statement about 2030 economics rather than about next year.
What happens to retailers that use both platforms?
They keep separate agreements until closing, and after that the practical question is whether one contract replaces two, which is where software and fulfilment savings are either realised or lost.
Which marketplace metric is most informative now?
Orders per store per week, because it captures demand and coverage together and cannot be inflated by a single large promotion.
