Anthropic’s S-1 for GTM Leaders
Anthropic filed to go public on October 26th and amended the filing on November 2nd. There’s been a ton of dialogue about it, particularly focused on compute costs, valuation and the AI economy.
While we enjoyed reading it from that angle also, the GTM numbers were also an area that jumped off the page for us. These are 7 GTM numbers from the S-1 that stood out to us.
1. Net revenue retention of ~900%
Anthropic reports net revenue retention of “approximately 900%” as of September 30, 2026. That is a wildly high number.
How they calculate it is by comparing revenue from customers in the latest three months against revenue from the same customers in the same three months a year earlier. Fixed-price Claude Pro, Max and Ultra subscribers are excluded, because their spend doesn’t expand or contract with usage.
In other words, customers who were paying Anthropic a year ago now pay about nine times as much in total. The filing credits “significant usage expansion as customers realize the value of deploying Claude across their organizations.”
2. $100K+ customers went from 950 to 11,900 in a year
As of September 30, 2026, Anthropic had:
- More than 11,900 customers with $100,000+ in trailing-twelve-month revenue, up from more than 950 a year earlier
- More than 1,900 customers at $1M+
- About 250 customers at $10M+
The $100K+ group generated $24.5B in the first nine months of 2026, or about 74% of revenue.
Anthropic doesn’t track “enterprise” as a segment at all. It uses $100K+ in annual spend as its stand-in for enterprise, because spend at that level is “generally characteristic of organizational rather than individual usage.”
3. Revenue up 1,206%, mostly on consumption
Revenue for the first nine months of 2026 was $33.2B, up from $2.5B in the same period of 2025.
Consumption revenue grew by $24.2B and subscription revenue by $6.5B. Anthropic calls its usage-based model “pay-for-intelligence,” and it is the “substantial majority” of revenue. Customers pay per token used. “A growing number of enterprise customers” sign non-cancelable annual or multi-year contracts with minimum spend commitments in exchange for a committed price list. Consumption made up 83% of revenue in 2025.
The filing ties the growth to product: “successive model and product releases that drove higher usage, expansion, and broader adoption.”
4. 44% of revenue comes through cloud marketplaces
The share of revenue sold through AWS, Google Cloud and Azure marketplaces:
- 2023: ~11%
- 2024: ~32%
- 2025: ~47%
- First nine months of 2026: ~44%
The structure is unusual. Anthropic describes a “joint go-to-market approach” with the cloud providers: it holds the direct contract with each customer and pays the cloud provider a fee. The filing says this avoids channel conflict and lets Anthropic set its own pricing. Many customers buy through both channels.
Those fees show up in sales spend. Sales, marketing and partnerships went from $322M to $5.5B (13% to 17% of revenue) in the first nine months of 2026, and $4.8B of that increase was fees paid to channel partners.
5. Top 5 customers are 25% of revenue, and shrinking as a share
Anthropic’s top five customers made up about 25% of revenue for the first nine months of 2026, and no single customer passed 10%.
The base is broadening fast. Customers outside the top five went from about 64% of revenue in Q1 2026 to about 79% in Q3, while revenue from each of the top five still hit a record in Q3.
There’s room to grow inside accounts too. Anthropic’s top 10 Fortune 500 customers spend less than 1% of their total expenses on Anthropic. That’s still more than eight times the average for its Fortune 500 customers at $100K+.
6. New models drive 80% of revenue within 6 months
Model versions released in the six months to September 30, 2026 accounted for more than 80% of Anthropic’s revenue in Q3.
The filing calls a “continuous and overlapping cadence” of releases “inherent to remaining at the frontier.” Each release opens new use cases, which brings in new customers and expands existing ones. Price comes down too: Opus 5.5 cut customer cost per task by about 40% compared with Opus 5.
There’s a seasonal effect as well. Total customer spend dropped about 20% in the two weeks to January 2, 2026, when many companies freeze code over the holidays.
7. Most adoption has been organic
“Much of the diffusion of Claude has been organic,” the filing says. Anthropic’s go-to-market and Applied AI teams amplify that by placing Claude in the tools customers already use.
Developers are the entry point. The filing calls them “powerful advocates” who “often serve as internal champions.” It also notes that non-technical teams are now adopting Claude Code and Claude Cowork for their own workflows.
Anthropic has organized its research priorities, product roadmap, and GTM and Applied AI teams around enterprise use cases. Its stated plan is to grow those direct teams, deepen cloud partnerships, invest in brand and expand internationally.
The bottom line
Anthropic’s S-1 shows a consumption business where customers expand about 9x in a year, $100K+ accounts drive three-quarters of revenue, close to half of sales run through cloud marketplaces, and new model releases account for most revenue within six months of launch.
