Anthropic’s IPO Countdown
Anthropic, the company behind Claude, is racing toward public markets at a remarkable pace. Its valuation has surged from approximately $120 billion in October 2025 to the current range of $380 billion to $1 trillion. Google confirmed a $380 billion valuation baseline in its latest investment round.
More critically, revenue growth is accelerating. In March 2026, Anthropic’s ARR reached approximately $19 billion, doubling from $9 billion at the start of the year in under four months. At the end of 2025, this figure was only about $1 billion—meaning Anthropic’s growth trajectory shows roughly 10x annual growth, extremely rare for scaled companies.
Revenue Growth and Valuation Multiples
| Time | ARR | Valuation | P/S Ratio |
|---|---|---|---|
| Dec 2024 | ~$1B | - | - |
| End 2025 | ~$9B | - | - |
| Mar 2026 | ~$19B | - | - |
| Latest | >$30B (est.) | $380B | ~12.7x |
If Anthropic IPOs at $380B–$1T with $30B ARR, the implied P/S multiple is 12–33x. Most SaaS companies trade at 5–15x P/S—Anthropic’s valuation embeds extremely high growth expectations.
IPO Timeline and Market Competition
Anthropic has hired IPO counsel and may launch as early as October 2026. It will compete with SpaceX (expected June) and OpenAI (expected H2) for institutional capital.
Three companies with combined target valuations of ~$4 trillion going public in the same window has almost no historical precedent.
Market pricing currently gives Anthropic a ~60% probability of IPO this year. Two variables to watch:
- Google’s investment constraints: As the largest outside investor, whether Google supports Anthropic disclosing financial data during fierce AI competition.
- Spillover from OpenAI’s performance gap: If OpenAI’s prospectus reveals growth slowdown, it could drag down the entire AI IPO sector’s valuation baseline.
