Where Value Might Accrue as AI Shifts from Training to Inference

A sample note on how to think about the AI value chain as usage grows: infrastructure, models, and applications, and the questions that separate durable positions from temporary ones.

The question

As AI moves from being built to being used, the economics may shift from one-time training efforts toward ongoing inference. That raises a simple question with complicated answers: who captures the value?

Three layers

  • Infrastructure: chips, data centers, power, and networks that run models.
  • Models: the systems themselves, whether proprietary or open.
  • Applications: products that put AI to work inside a specific workflow.

What to look for

Durable positions tend to combine something scarce (capacity, data, distribution, or trust) with a reason for customers to keep paying. This sample note will be expanded into a full analysis with read-throughs.

Investor read-throughs

What this means for you

Three lenses on the same analysis. Not investment advice.

Lens 01

Public Markets

Separate companies exposed to AI usage from those exposed only to AI build-outs.

  • Ask whether revenue grows with ongoing usage or with one-time infrastructure spending.
  • Look for disclosure on how AI features affect pricing, retention, and margins.

Lens 02

Private Markets

Underwrite distribution and data advantages, not model access alone.

  • Model capabilities can be widely available; proprietary workflows and customer relationships are harder to copy.
  • Stress-test gross margins under different compute-cost assumptions.

Lens 03

Entrepreneurs

Build where you own the workflow and the outcome.

  • Choose problems where AI improves an outcome a customer already pays for.
  • Design so that falling model costs help your margins rather than erode your differentiation.
