One of the most anticipated publications of the year in the business world arrives this June: the 2026 edition of “Las 500 empresas más importantes de México” (The 500 Most Important Companies in Mexico). Compiled by Expansión since 1975, this ranking has become an essential benchmark for understanding who drives the national economy.
More than just a list of companies ordered by sales volume, this exercise offers a detailed X-ray of the Mexican business fabric. It allows readers to observe which sectors are gaining ground, which ones remain pillars of the economy, and which ones face challenges that have slowed their growth.
It also reveals something that rarely changes: the massive corporations dominating the country’s economic activity remain at the top. With slight shifts in position, Mexico’s largest companies continue to show a remarkable capacity to withstand economic cycles, political shifts, and market transformations.
The highest tier of the ranking retains names that have become true economic institutions. Petróleos Mexicanos (Pemex) continues at number one despite its debt and volatility—which are explained in this issue—alongside companies like Walmart de México, América Móvil, FEMSA, the Comisión Federal de Electricidad (CFE), and Grupo Bimbo. Their presence at the top confirms the significant weight of both State-owned productive enterprises and some of the largest private groups in the country.
The ranking tells other stories as well. It showcases companies that have managed to climb positions in highly competitive industries where Mexican firms and multinationals compete for every point of market share. Furthermore, in 2026, 31 new companies joined the ranking, reflecting the momentum of other firms within the Mexican business ecosystem.
More than sales: a complete financial X-ray
The value of “The 500 Most Important Companies in Mexico” goes far beyond sales. The analysis includes key indicators such as profits, job creation, and other metrics that allow for an understanding of each company’s true scale.
Behind this edition is months of work carried out by the Expansión Intelligence team, which analyzes financial data, sector trends, and the behavior of the main corporations operating in the country.
The results show that despite an environment marked by inflationary pressures and an economic slowdown, large companies maintained a growth capacity superior to that of the Mexican economy as a whole. Combined, the companies in the ranking recorded sales of 18.6 trillion pesos in 2025, representing a real growth of 2% compared to the previous year.
Additionally, the ranked companies generated more than 5.1 million jobs in Mexico, consolidating their role as one of the primary engines of national economic activity.
The sectors dominating the economy
The analysis confirms that a few sectors continue to concentrate a large portion of the country’s business activity. Financial services, self-service retail, food and beverages, automotive manufacturers, oil and gas, telecommunications, insurance and bonding, department stores, automotive parts, and electricity and energy together account for more than 63% of the sales generated by the ranked companies.
By number of companies, financial services lead the list with 69 corporations, followed by:
- Insurance and bonding
- Food and beverages
- Automotive and auto parts
- Vehicle manufacturers
- Self-service retail
- Mining
- Logistics and transport
- Pharmaceuticals
- Chemicals and petrochemicals
A ranking that explains the country
Over five decades, “The 500 Most Important Companies in Mexico” has established itself as much more than a corporate list. It is a tool for understanding where the economy is headed, which industries generate value, which ones face difficulties, and where corporate power is concentrated.
The 2026 edition confirms that even in an environment of slower economic growth, large companies continue to be the driver of investment, employment, and productive activity in the country. As it has every year since 1975, it offers one of the most comprehensive and detailed X-rays of corporate Mexico.
