Bloomberg dropped a bombshell on March 27: Anthropic is considering going public as soon as October 2026, with early discussions already underway with Wall Street banks about leading roles on the listing.
The timing tells a story. And it’s not just about money.
The Numbers Behind the Confidence
Anthropic’s revenue trajectory is staggering even by AI standards:
- End of 2025: $9 billion annualized run rate
- Mid-February 2026: ~$14 billion
- Early March 2026: $19 billion+
- Current valuation: ~$380 billion
That’s a doubling in roughly two months. The primary driver? Claude Code. Anthropic’s coding agent tool went from surprise hit to enterprise staple, with usage up 300% and organizations integrating it across engineering teams at scale.
Paid subscribers have more than doubled in 2026 according to credit card data tracked by Indagari, confirming the growth isn’t just enterprise contracts — it’s broad-based adoption.
The Pentagon Saga Didn’t Slow Them Down
If anything, Anthropic’s clash with the US government over autonomous weapons use of Claude models may have accelerated consumer and enterprise adoption. The timeline:
- February 27: Anthropic designated a Pentagon supply chain risk after refusing autonomous weapons applications
- March 6: Anthropic vowed to fight in court, calling it retaliation
- March 26: Won a court order blocking the Trump administration’s ban
- March 27: IPO discussions reported
The court victory removed the most significant overhang on an IPO. The Pentagon feud may have actually strengthened Anthropic’s brand with the developer community and safety-conscious enterprises — the exact customers driving that $19 billion run rate.
Racing OpenAI to the Public Markets
The IPO would pit Anthropic directly against OpenAI in the public markets. Both companies are now exploring listings, and the timing matters: going first captures investor attention and sets the valuation benchmark.
Key differences in how they’d present to investors:
| Factor | Anthropic | OpenAI |
|---|---|---|
| Revenue run rate | ~$19-20B | ~$12-15B (estimated) |
| Core growth driver | Claude Code (developer tool) | ChatGPT (consumer + enterprise) |
| Governance | Public Benefit Corporation | Recently converted from nonprofit |
| Government stance | Refused Pentagon weapons use | Partnered with Pentagon |
| Safety narrative | Founded on AI safety mission | Increasingly enterprise-focused |
Anthropic’s PBC structure adds a wrinkle — it legally requires the company to consider public benefit alongside shareholder returns. How Wall Street prices that is an open question.
What This Means for the Ecosystem
An Anthropic IPO would be the first major “AI safety company” to go public. It would test whether the market values responsible AI development differently from pure capability plays.
For OpenClaw users specifically, it signals continued investment in the Claude model family. A publicly traded Anthropic needs to sustain growth, which means continued aggressive development of Claude Code, the API, and enterprise features — all of which directly benefit the OpenClaw ecosystem where Claude models are widely used.
The March of 2026 that Anthropic just survived — 14+ product launches, 5 outages, a model leak, a Pentagon designation, a source code exposure, and now IPO talks — may look in retrospect like the most consequential month in AI company history.
October is six months away. A lot can change. But the trajectory is clear: Anthropic is no longer just an AI research lab. It’s a $380 billion business preparing to face public market scrutiny — and it’s betting that its safety-first approach will command a premium, not a discount.
