Head-to-head across 4 Power Index axes: Momentum, Margin Discipline, Expansion Velocity, and Tech Adoption. Composite scores from 0–100. Source: Aisle Intelligence Power Index Q3 2026 — built from annual reports, trading updates, GS1 ESL data, and field observations.
"Mercadona's Portugal flywheel is the international expansion blueprint nobody in European grocery is seriously copying."
"Ocado's 98 tech adoption score is the highest in the index — but the gap between building best-in-class infrastructure and converting it into retail margin remains the central tension."
Mercadona and Ocado are both major operators in the European grocery landscape, but their Q3 2026 strategic trajectories diverge sharply. Mercadona holds a composite Power Index score of 74/100 vs 48/100 for Ocado — a 26-point gap that is structurally significant. The most important comparison isn't the total score but where the gap sits.
On Margin Discipline, the 59-point lead belongs to Mercadona (81 vs 22). That is the strategically decisive dimension in this matchup. Ocado leads on Tech Adoption (69 vs 98), which drives unit-economics compounding over 5–7 years. Mercadona leads on Expansion Velocity (63 vs 41) — the most visible near-term signal of where management is betting capex. Mercadona leads on Margin Discipline (81 vs 22), which determines how much optionality each operator has when the next consumer spending contraction arrives.
The strategic verdict: Mercadona's edge on composite score is material and likely to widen. Ocado's thesis — "Ocado's 98 tech adoption score is the highest in the index" — remains intact but faces pressure from the dimensions where Mercadona leads. For a European grocery strategy function, the most important question from this comparison is not who wins but which of the four axes matters most for your competitive exposure.
