THE STRATEGIC READING
Where checkout sits does not settle who operates it—or who has leverage.
Retained roles do not by themselves establish bargaining power. Compare whether buyers seek the provider’s service, whether the channel could route them elsewhere and whether the provider can reach them through other channels.[2]

Sources and notes
Case evidence. Partnerships Observatory, corrected grocery comparison and dated DoorDash/Instacart reconstructions, cutoff 7 October 2026, based on the companies' December 2025 launch descriptions and subsequent held material. DoorDash's handoff checkout and Instacart's embedded launch payment are different observations; an unidentified operator is not a transferred role. The source titles and passages remain available in the existing comparison disclosures.
Theory. Richard M. Emerson, "Power-Dependence Relations," American Sociological Review 27, no. 1 (1962), pp. 31-41, especially pp. 32-33. Dependence concerns valued outcomes and costly alternatives for the same outcome. The strategic application here is the Observatory's; the analysis examines how alternatives affect negotiating room.
