Mercadona Portugal: 55% of Households Now Shop at the Chain 2026

Mercadona Portugal has reached a striking milestone: more than half (55.6%) of Portuguese households now buy from its stores, either regularly or occasionally. The Spanish grocery chain, which has operated in the country for just seven years, is quickly becoming a household name.

This achievement comes as Mercadona holds a 7.4% market share in Portugal, placing it in the top five retailers. While still far behind local leaders Sonae (Continente) and Jerónimo Martins (Pingo Doce), which together control 49.9% of the market, Mercadona's rapid penetration signals a significant shift in Portuguese grocery shopping habits.

Mercadona's Rapid Rise in Portugal

Mercadona entered Portugal in 2016, a latecomer compared to established players. Yet its growth has been swift. The company's share of 7.4% already surpasses competitors like Intermarché, Auchan, and Aldi, according to recent data. This puts Mercadona in the top five of Portuguese retail, a notable feat for a relative newcomer.

The 55.6% household penetration is perhaps the most telling metric. It shows that Mercadona has successfully attracted shoppers across the country, not just in areas with a dense store network. This level of reach suggests strong brand acceptance and repeat visits.

Why Households Are Flocking to Mercadona

Mercadona's appeal in Portugal likely mirrors its Spanish success: a focus on own-brand products, competitive prices, and a streamlined shopping experience. The chain's 'Mercadona' brand products, known for quality and value, resonate with price-conscious Portuguese consumers.

Additionally, Mercadona's store expansion has made it more accessible. The company plans to end the year with 81 stores, up from 69 in 2025. This dozen-store increase will further boost visibility and convenience, driving even more households to try the chain.

Comparing Mercadona's Position: Spain vs. Portugal

In Spain, Mercadona is the undisputed leader with nearly 30% market share, far ahead of Carrefour and Lidl. In Portugal, its 7.4% share is modest by comparison, but the trajectory is upward. The key difference is time: Mercadona has operated in Spain for almost 50 years, while its Portuguese venture is only seven years old.

This context is crucial. Mercadona's Portuguese performance should be evaluated against its short tenure. Achieving over 55% household penetration in seven years is impressive and indicates strong potential for further growth.

Expansion Plans and Competitive Landscape

Mercadona is not content with its current position. The company plans to expand its store network to 81 locations by year-end, adding a dozen new stores. This expansion will likely target underserved areas and strengthen its presence in regions where it already has a foothold.

However, competition remains fierce. Sonae and Jerónimo Martins dominate with a combined 49.9% share, and discounters like Aldi and Lidl are also vying for shoppers' attention. Mercadona's ability to differentiate through its own-brand strategy and customer loyalty will be key to gaining further ground.

What This Means for Portuguese Consumers

For shoppers, Mercadona's growth means more choices and potentially better prices as competition intensifies. The chain's emphasis on quality own-brand products at affordable prices could pressure rivals to improve their offerings. Consumers stand to benefit from increased convenience and value.
