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.
"Carrefour's France strategy under Bompard is working but narrow — the transformation hasn't answered what Carrefour looks like in 2030."
"Tesco's UK business is genuinely healthy — but the Clubcard data moat hasn't translated into a successful format experiment outside the UK."
Carrefour and Tesco are both major operators in the European grocery landscape, but their Q3 2026 strategic trajectories diverge sharply. Tesco holds a composite Power Index score of 46/100 vs 35/100 for Carrefour — a 11-point gap that is structurally significant. The most important comparison isn't the total score but where the gap sits.
On Momentum, the 21-point lead belongs to Tesco (55 vs 34). That is the strategically decisive dimension in this matchup. Tesco leads on Tech Adoption (44 vs 57), which drives unit-economics compounding over 5–7 years. Tesco leads on Expansion Velocity (18 vs 22) — the most visible near-term signal of where management is betting capex. Tesco leads on Margin Discipline (43 vs 51), which determines how much optionality each operator has when the next consumer spending contraction arrives.
The strategic verdict: Tesco's edge on composite score is meaningful but not insurmountable. Carrefour's thesis — "Carrefour's France strategy under Bompard is working but narrow" — remains intact but faces pressure from the dimensions where Tesco 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.
