Overview

One System, Four Metros

The Texas Triangle is the densest part of the Texas Nexus; the Panhandle, Trans-Pecos, Rio Grande Valley and Gulf Coast anchors sit outside it. Its metros share labor markets, the ERCOT grid, intermodal rail and Gulf logistics. Tesla runs Giga Texas in Austin, Megapack in Brookshire near Houston and lithium refining in Robstown as one network, and Tier 1 and Tier 2 suppliers serve customers across all four metros.

Metros

The Four Metros

Starbase at Boca Chica incorporated as a city in 2025. The Cameron County land swap with the US Fish and Wildlife Service, Starship V3 production and SpaceX sites in Cameron, McLennan and Bastrop counties are driving growth that current metro definitions do not count.

Corridors

The Six Corridors

Supply chains in the Triangle cross city lines. Samsung Taylor's suppliers run through Round Rock, Hutto, Georgetown and Killeen, and Giga Texas depends on Brookshire, Robstown and Bastrop, none inside the Austin metro. Each corridor also carries residential growth; the San Marcos-New Braunfels stretch is one of the fastest-growing areas in the country.
