> **Key:** Anthropic has overtaken OpenAI on revenue, disclosing a **~$47B** annualized run-rate versus OpenAI's most recent **$25–33B** for 2026 — roughly **35% higher**, per Fortune.

## What happened

Anthropic reported a **~$47B** annualized revenue run-rate on its May 2026 reading, putting it clearly ahead of OpenAI's most recent disclosure of **$25–33B** annualized for 2026. That is a roughly **35%** lead and a genuine reversal in the AI race, which OpenAI had led for years. The climb over six months was near-vertical, and at that pace Anthropic is adding roughly **$96M** in annualized revenue per day.

- End of 2025: ~$10B annualized run-rate.
- February 2026: ~$14B. March: ~$19B.
- April 2026: ~$30B. May 2026: ~$47B.

The cause is the business model. About **80%** of Anthropic's revenue is enterprise plus API, led by Claude Code and agentic coding, versus OpenAI's consumer-heavy ChatGPT base and its thin (~5–6%) paid conversion. Anthropic says **8 of the Fortune 10** and **~70% of the Fortune 100** are Claude customers, with **1,000+** companies each spending over **$1M/yr**. Selling to developers and enterprises, it turns out, compounds faster than chasing consumer fame.

> Fortune reported Anthropic overtook OpenAI on revenue, hitting a ~$47B annualized run-rate versus OpenAI's most recent $25–33B for 2026 — roughly 35% higher — driven by an enterprise-and-API mix that is about 80% of its revenue.

## The catch

Read the number carefully. These are **self-disclosed annualized run-rates**, not audited GAAP revenue, and the two companies disclosed in different windows. The **$47B** May figure is partly a Sacra forward-extrapolation rather than a clean company disclosure, while the ~$30B April reading sits in a separate window. The honest framing is "ahead on revenue run-rate, on the latest disclosures" — not "Anthropic earns more than OpenAI, audited."

## What's next

The lead is not just on revenue. Anthropic's valuation reached **~$965B** after a ~$65B round, edging past OpenAI's **~$852B**, per CNBC. Anthropic also reported **Q4 2025 profitability** and has filed **confidentially for an IPO**, targeting around **October 2026** — a listing that would finally test these self-reported run-rate numbers against audited books. Watch whether the enterprise-and-API mix keeps compounding, and whether OpenAI's next disclosure narrows the gap.

## Key takeaways

- Anthropic disclosed a ~$47B annualized revenue run-rate for May 2026, roughly 35% above OpenAI's latest $25–33B for 2026.
- The driver is business model: ~80% of Anthropic revenue is enterprise and API, led by Claude Code and agentic coding.
- These are self-disclosed annualized run-rates, not audited GAAP revenue, and the $47B figure is partly an analyst extrapolation.
- Anthropic also passed OpenAI on valuation at ~$965B and filed confidentially for an IPO targeting around October 2026.
