DoorDash’s Instacart Deal Puts Commerce Media at the Center
DoorDash’s acquisition of Instacart for $17 billion brings together two delivery platforms, but the deal’s advertising businesses may be central to its strategic value. The transaction gives DoorDash a larger commerce-media operation and adds Instacart’s relationships with grocery shoppers and retailers to DoorDash’s existing restaurant-focused business.
The deal became official last week, following earlier reporting that it was under consideration. An investment-bank note from Needham, issued while the transaction was still a rumor, framed the combination as primarily about bringing together the companies’ advertising businesses. That interpretation shifts attention from delivery scale alone to the revenue mix each platform can offer brands.
Advertising’s growing role in the business mix
Instacart reported $297 million in advertising and other revenue in the second quarter, equal to 28.5% of its total revenue. DoorDash, meanwhile, passed a $1 billion annual advertising run rate two years ago, but has not disclosed a more recent figure for the business, according to the source material. Its advertising revenue is estimated there at around 10% of total revenue, rather than presented as a company-reported breakdown.
The distinction matters because the economics of delivery and advertising differ. Delivery operations involve costs associated with fulfilling orders, while ads can generate revenue without requiring the customer to pay more for the underlying order. Wedbush has described Instacart as bringing a marketplace spanning multiple grocery retailers, as well as advertising that lets brands pay for higher placement in search.
DoorDash has tried to expand its advertising capabilities beyond its own app. In 2025, it bought ad-tech company Symbiosys for $175 million, with the aim of extending its advertising beyond DoorDash’s platform. The acquisition of Instacart adds a business that has already established a substantial advertising operation, rather than relying only on DoorDash to develop that capability over time.
One purchase across multiple grocery retailers
Instacart’s position in grocery differs from that of a retailer-owned media network. A brand buying through an individual grocer’s advertising operation can reach that retailer’s shoppers; a national campaign may require separate arrangements with multiple chains. Retail media networks such as Kroger Precision Marketing and Albertsons Media Collective offer retailer-specific options, but their reach is tied to their respective businesses.
Instacart operates across many retailers, allowing brands to buy access to grocery shoppers through one platform rather than negotiate with each grocer separately. Its marketplace can combine shopping activity and baskets across participating retailers. That gives advertisers a way to plan across a broader grocery footprint, while the platform’s consumer relationships and retailer connections distinguish it from a single-chain network.
The companies also bring different commerce contexts. DoorDash has built direct relationships with restaurants, while Instacart connects consumers with grocery retailers. The source material puts DoorDash’s share of U.S. delivery spending at 59%, up from 44% five years earlier, and Instacart’s at 18%, down from 26%. Those figures suggest the businesses occupy different positions within delivery, while their combination could let brands reach consumers across restaurant, grocery and convenience occasions.
Measurement remains a qualification
Instacart has developed measurement for activity within its own app, including a 14-day attribution window, basket-level reporting, a clean room introduced in January and Media Rating Council accreditation for its impressions and clicks. These capabilities can help advertisers assess ad exposure and purchases made through Instacart.
They do not, however, establish what advertising caused across all of a retailer’s sales. Much grocery shopping still happens in stores, and the effect of Instacart advertising on those purchases is modeled rather than directly measured in the account presented here. The difference matters to brands seeking proof that a campaign generated incremental sales beyond the platform’s own basket.
Instacart also has consumer relationships that include shoppers who opt in to sharing loyalty-card data for retailer rewards. Its own planogram model gives the platform a role in determining product prominence in the shopping experience, including through brand deals. These features give Instacart assets beyond delivery volume, although they do not remove the limits of off-platform attribution.
The acquisition places commerce media more firmly within the strategic and financial case for a major deal. Rather than treating advertising as an experimental channel alongside delivery, DoorDash is acquiring an established ad business supported by shopper data and a multi-retailer marketplace. The combination’s eventual value to marketers will depend not only on reach and buying convenience, but also on how well the joined businesses preserve those capabilities and demonstrate impact beyond their own transactions.
