Where Is the Money Going?
Typical AI Capex Distribution
- 45% - GPUs and accelerators (primarily NVIDIA)
- 25% - Data centers (construction and expansion)
- 15% - Networking (InfiniBand, cables, switches)
- 10% - Storage (HBM, enterprise SSDs)
- 5% - Cooling and power
Spending Winners
| Provider | Product | Benefit |
|---|---|---|
| NVIDIA | H200, Blackwell GPUs | Primary beneficiary |
| ASML | Lithography machines | Record $11.5B profit 2025 |
| SK Hynix | HBM3e memory | Surpassed Samsung in profit |
| Advantest | Chip testing | Accelerating capacity |

Investor Pressure
Despite massive investments, Wall Street is increasingly skeptical:
The Hard Questions
- ROI: When will we see returns on these investments?
- Bubble: Are we over-investing in capacity?
- Depreciation: $680B in accumulated depreciation coming
- Competition: Is the arms race worth it?
Business Implications
Opportunities
- Cheaper cloud: Potential oversupply = better prices
- AI as commodity: Democratized compute access
- New services: Accelerated platform innovation
Risks
- Dependency: Vendor lock-in with hyperscalers
- Variable pricing: Costs may fluctuate with demand
- Temporary scarcity: GPU capacity remains limited short-term
2026 Predictions
- Q2: Pressure to demonstrate ROI increases
- Q3: Possible capacity consolidation
- Q4: First signs of enterprise AI profitability
