Marketplaces Becoming Retail Operating Systems
CFO of a European ecommerce logistics unicorn on the on-demand value chain
This shift means the winning marketplace is no longer just the app that gets the order, it is the operator that decides what gets stocked, where it sits, and how fast it reaches the door. Once a platform runs dark stores or dark kitchens, it stops earning only commissions and delivery fees, and starts capturing retail margin, advertising, and utilization gains from routing many orders through a controlled hub.

In the marketplace model, platforms mainly own traffic and last mile delivery. In grocery and food, most revenue still comes from merchant commissions and user fees. Vertical supply adds a new profit layer because the platform can buy inventory, control assortment, and push its own brands or partner brands in the app.

Dark stores and dark kitchens also change the physical workflow. Instead of riders crisscrossing city blocks for one order at a time, orders are picked from a small dedicated site and dispatched from a hub, which improves order stacking and route density. That is why operators like Rappi tied dark kitchens to a hub and spoke logistics model.

The tradeoff is that supply side control is much harder than demand aggregation. Dark stores add pickers, rent, inventory risk, and spoilage. In online grocery, small baskets are a structural problem, and research on mature dark stores points to contribution margin working only with tight assortments, high order density, and better gross margin from procurement.
The next phase of on demand will be defined by which platforms can turn customer traffic into owned supply infrastructure without losing efficiency. As markets mature, the strongest players will look less like pure marketplaces and more like compact retail operating systems, combining app demand, merchant ads, private fulfillment nodes, and repeat ordering into one denser, more profitable loop.
