The AI Infrastructure Bottleneck: Physics, Not Funding
The AI infrastructure — as explored in the economics of AI compute infrastructure — buildout has entered a phase where Blackwell supply—not capital—is the primary constraint .
Key Components
The Constraint Cascade
Constraints have shifted from capital to physics:
Stargate Status
Oracle has pushed ahead with massive infrastructure buildout on OpenAI's behalf, borrowing heavily. The Abilene, Texas flagship facility became partially operational in 2025.
The Reality
AI scale is increasingly governed by physics, not funding . The constraint is now power, memory, and cooling infrastructure.
