Summary
Situational Awareness made a $400 million investment in Source Foundry, a semiconductor manufacturing startup focused on new lithography tools. The company aims to attack one of the most concentrated layers of the chip supply chain, where ASML holds a dominant position. Source Foundry was founded in 2025 and already has backing from investors like Sequoia Capital. The deal reflects how AI capital is migrating from applications toward physical bottlenecks in infrastructure.
Why it matters
AI growth depends on an industrial chain much wider than Nvidia and data centers. Lithography, memory, interconnect, energy and advanced packaging can become more important constraints than model design. Sophisticated money is looking for exposure to those layers because they are hard to replicate and can capture value even if the model leaders change.
Practical implications
- When evaluating AI trends, also follow infrastructure, semiconductors, energy and networks, not just new models.
- For tech businesses, favor services that can run across multiple hardware generations.
- Avoid AI cost projections that assume the price of compute will fall in a straight line.
