The Architecture of Constraint: Three Bottlenecks Money Cannot Solve
NVIDIA's ability to ship GPUs depends on three critical chokepoints, none of which it controls. Understanding these constraints explains why money alone cannot solve the AI compute — as explored in the economics of AI compute infrastructure — shortage.
Key Components
Bottleneck 1: High Bandwidth Memory (HBM)
"We have sold out our entire 2026 HBM supply." — SK Hynix CFO
Bottleneck 2: CoWoS Packaging
TSMC Monopoly: The only advanced packaging provider at scale
The Layer 1 Insight
Physical constraints define AI's ceiling. HBM, CoWoS, and advanced logic form interdependent bottlenecks. NVIDIA's supply agreements create years-long structural advantage.

Bottleneck 1: High Bandwidth Memory (HBM)
The HBM Triopoly:
SK Hynix — 50% market share
Samsung — 40% market share
Micron — 10% market share
“We have sold out our entire 2026 HBM supply.” — SK Hynix CFO
Stargate Demand: 900K wafers/month by 2029 = 40% of global DRAM output
Bottleneck 2: CoWoS Packaging
TSMC Monopoly: The only advanced packaging provider at scale
Capacity sold out through 2025-2026
Growth: 75K → 95K → 135K wafers/month (2025-2027)
NVIDIA controls 70%+ of capacity
Bottleneck 3: Energy Infrastructure
Grid Saturation:
7-year wait for grid interconnection
Power demand: 61.8 GW → 134.4 GW (2025-2030)
$1 Trillion utility CapEx 2025-2029
