I’ll be honest—this news caught me off guard.

On April 17th, Anthropic’s implied valuation quietly crossed $1 trillion on secondary markets, briefly but genuinely surpassing OpenAI. Then came another bombshell: their Annual Recurring Revenue (ARR) had topped $30 billion, again beating OpenAI.

This isn’t just about who’s making more money.

As someone who’s spent five years in the AI industry, I’m more interested in: How did Anthropic pull this off? And what signal does this send for the entire sector?

Let’s Talk About That $30B First

What does $30B ARR actually mean?

For context:

  • OpenAI: ~$25-28B (Q1 2026 estimate)
  • ByteDance’s AI business: ~$8B (estimated)
  • Alibaba Cloud AI: ~$6B (estimated)

Anthropic achieved global leadership in just two years, relying on a single model family—Claude.

Here’s what’s interesting: A year ago, most people saw Anthropic as “one of OpenAI’s competitors,” not “the one that surpassed OpenAI.”

So how did they do it?

It’s Not Just About Having Better Models

Here’s my take—Anthropic won on three fronts:

First, the market value of “safety” was underestimated.

From day one, Anthropic played the safety card. Dario Amodei reportedly left OpenAI over disagreements about safety priorities. In hindsight, that was the right call—enterprise customers, especially in finance, healthcare, and legal sectors, are willing to pay for “safe and controllable” models.

Claude’s “Constitutional AI” approach gave them a differentiated selling point. This isn’t tech showboating; it’s business strategy.

Second, Anthropic’s product strategy is more… disciplined.

This might sound counterintuitive, but Anthropic’s model iteration pace is actually slower than OpenAI’s. GPT-4, GPT-4 Turbo, GPT-5, GPT-5.4, GPT-6… OpenAI’s release cadence is dizzying.

Anthropic? Claude 2, Claude 3, Claude 3.5, Claude 4… In over two years, major version updates have been sparse.

This “discipline” has a benefit: Enterprise customers don’t have to re-adapt APIs every few months. In B2B, stability beats novelty.

Third, pricing strategy as precision strike.

Claude has always been slightly cheaper than GPT while matching performance. For cost-sensitive enterprise clients, that’s irresistible.

But the Revenue Isn’t the Scary Part

You might say: Anthropic won on business model, so what’s scary about that?

The scary signal is this: Anthropic is accelerating closed-source.

In early April, Anthropic released Claude Mythos Preview—a technically groundbreaking version with major reasoning improvements—but chose complete closure. Even API documentation became more restricted.

This mirrors OpenAI’s path exactly. GPT-3 was open source; GPT-4 went closed. Now Anthropic is following suit.

What this means for China’s AI industry, I don’t need to spell out.

Over the past two years, domestic LLM companies (DeepSeek, Zhipu, Moonshot, etc.) have been rapidly catching up. DeepSeek V4 has even matched Claude Opus 4.6 in some benchmarks.

But if all leading players go closed-source, we lose not just technical references, but the entire collaborative network of the open-source ecosystem.

Open vs. closed source has never been just a technical choice—it’s about industry power dynamics.

My Personal Take

I genuinely admire Anthropic’s business success. They proved that in an OpenAI-dominated market, you can still break through with differentiated strategy.

But as someone who believes in open source, I’m wary of Anthropic’s closed-source trajectory.

Technology itself is neither good nor evil, but the people building it have a responsibility to consider impact. As AI becomes more powerful, the choice between “open” and “closed” will profoundly shape the industry’s future.

One question to leave you with: If GPT-6 and Claude 4 both go fully closed-source, what should China’s LLM companies do? Keep reinventing the wheel from scratch, or find new technical paths?

That question might be more worth thinking about than “who made $30B.”
