DoorDash has agreed to acquire Maplebear Inc., the parent company of Instacart, in a cash-and-stock transaction valued at approximately $17 billion. The deal, announced October 29, 2026, remains subject to antitrust review and shareholder approval; closing is not expected until the end of 2027 or the first half of 2028.
What the Deal Costs
The agreed price carries a meaningful premium over where Instacart shares traded before acquisition talks became public.
Per the deal terms, DoorDash will pay $65 per share, at least 75% of it in cash, with the remainder potentially in DoorDash stock. That price represents a 26% premium to Instacart’s closing price on October 22, 2026, the last trading day before media reports of a possible transaction surfaced.
Instacart’s board voted unanimously to approve the agreement. Shareholders controlling roughly 19% of Instacart’s outstanding shares have already committed to vote in favor, according to the companies’ announcement.
Two Different Platforms, One Proposed Company
DoorDash and Instacart built their businesses around different strengths, and the proposed deal is designed to combine them.
DoorDash built its business on restaurant and takeout delivery, scaling a broad last-mile logistics network across U.S. cities. Instacart took a different path, focusing on grocery delivery, retailer relationships, and an enterprise technology platform that powers fulfillment and digital storefronts for grocery chains’ own websites.
The proposed combination would bring those capabilities under one roof. Instacart’s brand, app, and enterprise products are expected to continue operating separately until the transaction closes, per the companies.
What the Companies Are Promising Consumers
The companies project expanded store access and potential membership savings, though both depend on a deal that has not yet closed.
According to the companies’ announcement, Instacart customers could gain access to more than 50,000 additional stores reachable through DoorDash’s network. The companies also say a unified membership could eventually replace separate DashPass and Instacart+ subscriptions, with an estimated $100 million in annual membership-fee savings for customers, though that figure is a projection rather than a guaranteed outcome.
Those benefits are conditional on how the companies integrate pricing, subscriptions, and app experiences after closing.
The Regulatory Hurdle Is Real
The transaction faces antitrust review in the United States and additional approvals in Canada and Israel before it can proceed.
The deal requires clearance under the Hart-Scott-Rodino Act, plus separate regulatory approvals in Canada and Israel. The companies have set an expected closing window of the end of 2027 or the first half of 2028, reflecting a timeline that encompasses multiple regulatory conditions.
Combining two major U.S. delivery intermediaries raises unresolved questions regulators will need to assess. Those questions include whether the merged platform could exercise greater influence over merchant commissions, consumer fees, or the contract terms available to grocers and restaurants that depend on delivery partners. These are open questions, not settled outcomes. Readers seeking broader context on antitrust review of large technology platforms may find recent developments in Europe instructive.
The Bigger Strategic Picture
The acquisition would accelerate DoorDash’s existing effort to expand beyond restaurant delivery into grocery, retail, and fulfillment.
DoorDash has been working to position itself as a broader local-commerce platform. Instacart’s retailer relationships, fulfillment infrastructure, and grocery-specific technology would add category expertise that could take substantial time and investment to build through organic expansion alone.
Instacart would end its run as an independent company if the transaction closes, at a price that reflects a meaningful premium over where shares traded before acquisition talks became public. Whether consumers, merchants, or delivery workers come out ahead depends on how regulators assess the deal and how the companies execute if it closes.
