Every market has its titans. In the most significant industrial regions of northern, central, and Bajío Mexico, nine companies occupy more space than any other company. Where they operate, they create structural dependencies, influence pricing, alter logistics routes, and shape infrastructure priorities.

One of the clearest cases is Nissan in Aguascalientes. Amid trade tensions, global shifts, and rumors of relocation, the automaker didn’t just confirm it would remain in Mexico—it redefined that presence from within.

After appointing its first Mexican CEO in April, Nissan announced the closure of its CIVAC plant in Morelos and began moving operations to the Bajío. The transition will conclude in 2026, with Aguascalientes as its new center of gravity. But Nissan doesn’t just operate there—it structures the market. On its own, it accounts for 21% of the region’s total industrial gross leasable area, in an ecosystem where three out of every ten tenants—and six out of every ten square meters—belong to the automotive sector. COMPAS follows with 8%, and behind it, a dozen major players jointly hold another 22% of inventory. Still, the Herfindahl-Hirschman Index barely reaches 568 points, indicating a market with strong players but no monopolies.

While Aguascalientes orbits around Nissan, other markets reveal their focus through the company that occupies the most space. In Mexico City, for example, Mercado Libre holds 7% of industrial inventory, where last-mile logistics are just as strategic as demand for mass consumer goods.

In the northern border region—home to many export-oriented industries—Electrolux in Ciudad Juárez (home appliances), Footprint MX in Mexicali (sustainable packaging), Whirlpool in Monterrey (white goods), and Corning in Reynosa (specialized glass and telecoms) each account for between 2% and 7% of their respective markets. And in Guadalajara—Bajío’s hub for agribusiness, electronics, and consumer goods—Flex represents 4%.

Some companies, however, don’t dominate just one market—they span several. General Motors leads in Guanajuato, Saltillo, and San Luis Potosí—all hubs for vehicles, engines, and auto parts—with shares ranging from 6% to 8%. Samsung, meanwhile, concentrates its industrial footprint in Querétaro and Tijuana, two critical nodes for consumer electronics, semiconductors, and optical components, with 3% and 2% of inventory, respectively.
