southwest data center mega-hub emergence

Executive Summary

The Southwest region—New Mexico, Arizona, and Texas—has emerged as America’s dominant data center mega-hub in 2025, capturing $403 billion in total investment and 57.7% of all new mega-projects (>$10B) announced in Q4 2025 alone.

This represents a fundamental geographic shift in U.S. data center development, driven by:

• Regulatory certainty (vs. coastal opposition)
• Grid capacity (proactive utility expansion)
• Land availability (large industrial sites)
• Renewable energy (abundant solar potential)
