The Texas Triangle
Where power, industry, capital, and geography meet.
Published October 5, 2026 · Selected evidence and editorial interpretation
A region becomes economically interesting when its capabilities reinforce each other. The Texas Triangle thesis asks whether the DFW, Houston, and Austin–San Antonio corridors can connect capital, manufacturing, energy expertise, and technology into a stronger industrial system. That is an interpretation to investigate, not a guarantee of regional or stock-market outperformance.
Start with a factory that actually began producing
On December 17, 2025, Texas Instruments announced the start of production at its SM1 semiconductor fab in Sherman, North Texas. The company said the facility would ramp with customer demand and described its output as analog and embedded processing chips. [1]
Sherman sits north of the Triangle’s DFW vertex. It is relevant as part of the surrounding industrial network, not as a reason to redraw the geography. These chips also should not be confused with the advanced AI accelerators attracting most market attention. Industrial expansion has more than one semiconductor story.
Texas is not one interchangeable power location
ERCOT’s February 2026 overview discussed Far West Texas load growth outpacing transmission import capability. It described a region that still needs imported power when local renewable output is low. [2]
Far West Texas is outside the Triangle. Its relevance here is a boundary condition: a statewide energy story cannot establish the operating conditions at a specific site. Regional strengths and local delivery constraints can coexist.
What a cluster can change
Related businesses can share skilled labor, service providers, technical knowledge, and customers. Shorter commercial and geographic distances may make it easier to solve problems jointly. These are potential cluster benefits, not proof that every new project gains an advantage.
The stronger version of the Texas thesis is about complementary capabilities becoming productive together. A weaker version simply adds up announced spending across unrelated locations. We favor the first question because it has economic content.
The investor’s useful takeaway
The Sherman example shows why production milestones matter; the ERCOT example shows why geography remains specific. Together they support a more careful regional perspective: Texas has substantial industrial activity, but capacity arrives unevenly and at different speeds.
A growth region can host excellent businesses and disappointing investments at the same time. Demand, execution, financing, and price still affect the outcome. This brief offers context, not a regional allocation recommendation.
