Cloudflare has started charging for the agent internet. The company recorded its first revenue from products built for a web where AI agents, not people, do most of the browsing, and its chief executive said OpenAI is already paying for hints that tell its crawler when pages change. Revenue rose 39% to $782.5 million in the third quarter, the fastest growth in nearly four years. The message to publishers is blunt: the traffic is changing, and someone will pay for it.
What Act 4 is
The new products sit under the name Act 4, Cloudflare’s label for tools that create a new business model for the internet. They cover pay per crawl, micropayments for content use, and discounts for agents that explain what they are doing.
Two payment products, the Monetization Gateway and Pay Per Use, moved into beta on 30 September. Cloudflare gave no figure for Act 4 revenue on the call. That silence matters: the first revenue is real, but its size is still a secret.
OpenAI pays for the hints
The one paying customer named on the call is OpenAI. Under a research pilot announced in July, Cloudflare tells OpenAI when a page has changed, so its crawler does not keep refetching the same page. The hints save OpenAI money and give Cloudflare’s customers fresher data in return.
Chief executive Matthew Prince said OpenAI is paying for that service, and he expects other AI companies to do the same. The pilot began without pricing; it now has a paying customer. That turns a research experiment into a commercial precedent for the whole industry.
Welcome agents or block them
Cloudflare’s pitch to website owners is a choice: welcome agents or block them. Customers who want agent traffic get help attracting it and handling it efficiently, while customers who see agents as a threat can block them and are not charged for that traffic.
Prince illustrated the scale with a dinner search: an agent might pull menus from 1,000 restaurant sites, while the user visits only one. He expects nonhuman traffic to reach 1,000 times human traffic within five years, sooner than he forecast before.
Our Read
This is the first real money in the business of charging AI agents for the web. Until now, pay per crawl and agent micropayments were conference ideas; Cloudflare has turned one into recognised revenue, with OpenAI as the proof today.
The open question is who gets paid: the call did not say whether the websites whose pages OpenAI reads get a share of the money. That gap is where the next fight over AI and the web will be fought.
The quarter around the announcement was strong by any measure. Cloudflare passed $3 billion in annualised revenue, added a record 158,000 paying customers, and passed 10 million active developers, more than double the count at the start of the year.
It forecast fourth-quarter revenue of $845 million to $846 million and now expects to reach GAAP profitability in that quarter, two years ahead of its earlier target of the end of 2028. Shares rose sharply after the report as investors repriced the agent opportunity.
Why It Matters
For anyone who publishes on the web, agent optimisation is becoming a discipline with a price tag, not just a settings page. Sites will have to decide whether to be read efficiently by agents and get paid for it, or to block agents and lose the traffic entirely.
Cloudflare sits in the middle of that decision as gatekeeper, toll collector and broker, and it is now being paid for all three roles at once. Persistent agents that keep working between prompts, like the ones Perplexity now sells, will only make that traffic bigger.
Background
Cloudflare has spent the past year building the plumbing for this shift. It launched pay per crawl in private beta in July 2025, letting publishers charge AI crawlers per request, and later moved toward paying publishers when their content appears in AI answers.
Its AI Crawl Control tool, available on every plan, lets sites permit or deny individual AI crawlers. The Act 4 revenue is the first sign that the plumbing is starting to pay. The lesson for publishers is the same one our GEO guide sets out: being cited inside AI answers is now the traffic that matters.
