DoorDash announced on Thursday, October 29, that it has entered into a definitive agreement to acquire Instacart — operated by Maplebear — for $17 billion. Each Instacart share will be purchased at $65, with at least 75% of the consideration in cash. Shareholders can elect cash, DoorDash stock, or a combination of both, subject to proration so that DoorDash stock does not exceed 25% of the aggregate deal value. Both companies' boards of directors have approved the transaction, which is expected to close in late 2027 or the first half of 2028, subject to regulatory approval and customary closing conditions.
The announcement concludes a negotiation process that began being publicly mapped last week, when Bloomberg — and subsequently Reuters and the Wall Street Journal — reported that DoorDash was in advanced talks to buy Instacart. Before that, Instacart itself had conducted rounds of conversation with both Uber and DoorDash; Uber's walkaway on October 23 already indicated that DoorDash was the most likely option. What changed? DoorDash made a definitive offer, not just a term sheet.
To understand the scale of the operation, it is useful to look at the two businesses separately. Instacart operates the widest grocery delivery platform in the United States, with partnerships ranging from regional supermarkets to major chains like Albertsons, Kroger, and Walmart. According to the company's own data, more than 250,000 commercial establishments use its online grocery technology tools. DoorDash, in turn, is the country's largest restaurant delivery platform, with over 250,000 restaurant partners and a logistics network covering virtually the entire American territory.
The combination of the two platforms creates the largest on-demand delivery operator in the country — and perhaps one of the largest in the world by transaction volume. DoorDash now indirectly controls the largest share of the US grocery delivery market. Just for context, grocery delivery in the United States generated more than $50 billion in 2025, according to Statista projections, and is expected to continue growing at double-digit rates in the coming years.
The merger strategy makes sense from DoorDash's perspective. The company has invested heavily in fulfillment for its own delivery partners — the DoorDash Storefront, which allows restaurants and stores to operate their own online ordering platforms with DoorDash's logistics technology behind the scenes. With Instacart, the company gains not only the consumer base, but the entire grocery technology stack it already sells as SaaS to retailers. DoorDash's official announcement emphasized exactly this point: "we can create new opportunities for our retail partners and brands," the company said in the press release.
For retailers, the consolidation is a double-edged sword. On one hand, having access to Instacart's grocery technology combined with DoorDash's last-mile logistics could significantly reduce operational costs — especially for small and medium retailers who lack their own delivery infrastructure. On the other hand, the concentration of power in a single company raises legitimate antitrust concerns. Instacart, alone, was already considered one of the two dominant players in grocery delivery, competing directly with Walmart and Target at scale. With DoorDash, the combined entity will control an even larger share of the market.
The $17 billion price tag reflects Instacart's growth value, not necessarily its current profitability. The company still operates with tight margins in grocery delivery — a historically difficult model where the cost of sourcing, selecting, and delivering perishable products in short time windows dilutes all margin. DoorDash likely expects that integration with its restaurant delivery network will generate economies of scale in logistics, technology, and consumer acquisition that will finally make grocery delivery profitable at scale.
The decision to keep Instacart as a separate brand — operating independently until closing — is strategic. Brand dilution is a real risk in operations of this size: consumers who use Instacart for grocery do not want to see the brand replaced by DoorDash overnight. DoorDash has already done this with other businesses (WeWork, Wolt in Europe) without destroying brand value.
From a regulatory standpoint, the operation will face antitrust scrutiny in the US and possibly Europe. the Department of Justice and the FTC will have to approve the transaction under the Hart-Scott-Rodino Act, and the European Commission may open an investigation under the EU merger regulation. The US review period can take 6 to 18 months, which explains the expected closing window of late 2027 or early 2028.
What DoorDash gains with this goes beyond delivery. With Instacart and DoorDash under one roof, the company gains access to grocery purchase data — patterns of consumption, purchase frequency, seasonal preferences — data that can be monetized through advertising, credit cards, financial services, and potentially AI models that predict local demand in real time. It is the same strategy that Amazon and Alphabet have been using for years: accumulating consumer data to create high-retention ecosystems.
The question that remains is whether, by consolidating delivery into a super-app, DoorDash is building the definitive infrastructure of on-demand commerce or creating an antitrust target so large that regulators will force it to divest part of the business — as happened with the FTC's unsuccessful attempt to block Facebook's acquisition of Instagram in 2012. Time will tell whether DoorDash becomes the Amazon of delivery or gets fragmented under regulatory pressure.
