Consumer Edge’s figures offer a different picture of the competitive landscape. DoorDash’s share of U.S. delivery-platform spending increased from 44% to 59% over five years, while Instacart’s declined from 26% to 18%. Uber Eats remained just below 20%.[2] These figures measure broader delivery-platform spending, not third-party grocery delivery. They demonstrate DoorDash’s expanding position and Instacart’s relative decline, but cannot establish the combined grocery-market concentration alleged by AELP.
That distinction leaves DoorDash exposed to meaningful regulatory scrutiny without establishing that authorities will block the acquisition. Both companies operate in grocery delivery, and Reuters reports that their overlapping activities are expected to attract U.S. antitrust attention.[3, 4] New York City’s Department of Consumer and Worker Protection had also expressed concerns about consolidation in the delivery industry before the announcement.[4]
There is a precedent for federal intervention in grocery-related consolidation. In 2024, the Federal Trade Commission (FTC) sued to prevent Kroger’s $24.6 billion acquisition of Albertsons, arguing that the supermarket chains were direct competitors and that their combination would eliminate competition between them.[5] The FTC authorized both an administrative complaint and federal litigation.[5] DoorDash and Instacart, however, are delivery and grocery-fulfillment businesses rather than competing supermarket chains. The Kroger case establishes that grocery-sector consolidation can attract formal intervention, not that the same outcome awaits this transaction.
DoorDash is buying deeper grocery capabilities rather than entering an entirely new market
DoorDash’s strategic rationale is more concrete than its regulatory position. The company began grocery delivery in 2020 and now lists the full inventory of 2,700 Kroger stores in its marketplace. It has also expanded its retail relationships, including through Costco delivery.[2] Instacart brings a different capability: experience in grocery selection, substitutions and fulfillment. Combining that expertise with DoorDash’s delivery infrastructure would increase Instacart’s stated store coverage from 100,000 to 150,000 locations.[3]
The acquisition therefore represents an expansion of existing capabilities rather than entry into an entirely new business. DoorDash already has a growing grocery operation; what it is purchasing is additional fulfillment expertise, retailer coverage and access to Instacart’s established grocery platform. That provides a credible operational rationale, but retailer relationships will require attention during integration. Instacart currently offers Walmart delivery, whereas DoorDash discontinued its Walmart delivery service in 2022.[2] The proposed expansion in store coverage does not, by itself, establish that every existing commercial relationship will remain intact.
Customer savings offer a clear benefit, but the financial returns remain unproven
The financial justification is considerably less developed. DoorDash is offering $65 per Instacart share in cash and stock, approximately 25% above Instacart’s October 22 closing price.[1] Against that premium, the companies estimate that combining DashPass and Instacart+ could save customers $100 million annually in membership fees.[1] This is a consumer benefit, not a demonstrated improvement in DoorDash’s revenue, operating profit or cash flow.
The distinction is consequential. Customers paying for one membership instead of two could benefit immediately from the proposed arrangement, but those savings do not establish how much additional economic value DoorDash will capture. The acquisition has no quantified net earnings benefit in the announced rationale that demonstrates how the premium will be recovered. Integration expenses, financing costs and the eventual contribution to profitability will determine whether the additional capabilities justify the consideration.
The cash-and-stock structure also leaves the precise financing allocation and resulting balance-sheet consequences unresolved. The amount of cash deployed, potential shareholder dilution, incremental borrowing and pro forma leverage have not been quantified. DoorDash’s financial exposure therefore depends heavily on what happens after completion, rather than on the headline purchase price alone.
The ultimate test will be whether integration delivers returns that justify the acquisition premium
A failed transaction would mean Instacart shareholders do not receive the proposed $65-per-share consideration, which remains conditional on shareholder approval and regulatory clearance.[1, 4] DoorDash shareholders face a different risk: the acquisition could proceed, but the resulting financial benefits might not justify the premium. Uber and other delivery providers could also gain business if retailers or customers turn to alternative platforms after a failed transaction, although no actual customer migration or retailer commitments establish that outcome.[1, 2]
The expected completion window is late 2027 or the first half of 2028, subject to shareholder approval and regulatory clearance.[4] An independently supported grocery-delivery market-share assessment and a formal FTC or DOJ determination will establish whether the concentration argument becomes a concrete obstacle. If the transaction proceeds, the first post-acquisition financial results will provide the more consequential test: realized net synergies, integration costs, incremental earnings and cash-flow contributions.
For DoorDash, the central economic risk is not simply paying a 25% premium for Instacart. It is completing the purchase without generating enough additional earnings to justify it. The company has identified $100 million in potential annual customer savings and 50,000 additional store locations; its shareholders will ultimately need to see those operational benefits translate into measurable financial returns after integration costs.
