DoorDash has agreed to buy grocery delivery company Instacart in a deal valuing its equity at about $17 billion, bringing two major US delivery platforms under a proposed common owner.

The agreement, announced by both companies on 29 October 2026, offers Instacart shareholders $65 per share, a 26% premium to its closing share price on 22 October. At least 75% of the total consideration will be cash, with DoorDash shares accounting for no more than 25%.

The deal is expected to close in late 2027 or the first half of 2028, subject to shareholder and regulatory approvals. Until then, the businesses will operate independently. DoorDash says it intends to retain Instacart’s brand, app and enterprise technology products.

For supermarkets, the most important question is not the headline purchase price but how the merger would reshape the options available to retailers. Instacart supplies ordering, fulfilment, advertising and data technology to grocery businesses, while DoorDash operates a delivery marketplace and logistics network.

A retailer using these services may benefit from broader consumer reach and integrated technology, but could also face questions about pricing, data access and negotiating leverage. The companies have said local grocers will not be required to use an exclusive grocery delivery platform. That commitment will be important to examine as detailed terms and regulatory reviews develop.

The transaction could also strengthen the role of retail media in online grocery. Brands increasingly pay to reach shoppers on digital ordering platforms, so how advertising products and reporting tools are combined may matter to both supermarket operators and FMCG suppliers.

Instacart separately reported third-quarter 2026 results showing gross transaction value growth of 15% and revenue growth of 17%. Those figures show the scale of its existing grocery activity; they do not establish what the combined platform’s future pricing or market share will be.

Competition authorities will assess the transaction before it can proceed. Retailers should therefore avoid treating proposed integration plans as completed operational changes.

The next milestones are Instacart shareholder approval and regulatory reviews in relevant markets.
