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.
"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."
"REWE Group's EUR 7B debt load is the subtext of every strategic conversation about German grocery."
Ocado and REWE Group are both major operators in the European grocery landscape, but their Q3 2026 strategic trajectories diverge sharply. REWE Group holds a composite Power Index score of 57/100 vs 48/100 for Ocado — a 9-point gap that is closer than it appears from the headline numbers. The most important comparison isn't the total score but where the gap sits.
On Margin Discipline, the 38-point lead belongs to REWE Group (60 vs 22). That is the strategically decisive dimension in this matchup. Ocado leads on Tech Adoption (98 vs 61), which drives unit-economics compounding over 5–7 years. REWE Group leads on Expansion Velocity (41 vs 44) — the most visible near-term signal of where management is betting capex. REWE Group leads on Margin Discipline (22 vs 60), which determines how much optionality each operator has when the next consumer spending contraction arrives.
The strategic verdict: REWE Group's edge on composite score is narrow and contested — watch the next 12–18 months for inflection. Ocado's thesis — "Ocado's 98 tech adoption score is the highest in the index" — remains intact but faces pressure from the dimensions where REWE Group 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.
