The artificial intelligence startup Anthropic has closed a Series H round of over $4 billion, raising its valuation to $200 billion, surpassing OpenAI ($150 billion). The company, co-founded by former OpenAI employees, is nearing $5 billion in annual recurring revenue.
The battle for dominance in artificial intelligence has a new leader in valuation. Anthropic, the startup founded by brothers Dario and Daniela Amodei, has closed a Series H funding round of over $4 billion, placing it at a valuation of $200 billion (around €180 billion). With this figure, the company surpasses OpenAI, valued at $150 billion in its last round in March 2026, and becomes the most valuable private artificial intelligence company on the planet.
The operation has been led by heavyweights in venture capital such as Altimeter Capital, Greenoaks, Dragoneer, and Sequoia Capital. Other participants include Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ, and XN. Additionally, Amazon, which was already a strategic partner, has injected another $5 billion in a computing deal that strengthens its bet on the Claude platform, Anthropic's AI assistant.
A valuation that doubles in five months
The valuation leap for Anthropic is staggering. In February 2026, the company had raised $30 billion at a valuation of $380 billion. Just five months later, its value has more than doubled to $200 billion. Behind this surge is a revenue growth that few startups can match: the company is nearing $5 billion in annual recurring revenue (ARR), with demand for its assistant Claude saturating its infrastructure during peak hours.
Anthropic's CFO, Krishna Rao, explained that the new capital will be used to scale computing capacity and bring Claude to more work environments. “We are investing in infrastructure to meet the growing demand and ensure that our models remain the safest and most capable,” he stated in an internal communication accessed by the market.
To put it in perspective, OpenAI, Anthropic's major rival, reached a valuation of $150 billion in its last round in March 2026. Although it remains a titan in the sector, Anthropic has taken the lead in just one quarter. According to analysts, the key has been the ability to attract top talent and build a responsible and aligned AI narrative that resonates with investors.
Talent as a differential asset
Brothers Dario and Daniela Amodei left OpenAI in 2020 over differences regarding model safety. They took with them a dozen top researchers. This brain drain, more than any patent, has been the true asset that is now worth $200 billion. “It’s not the technology that differentiates two AI startups: it’s the ability to attract and retain the people who build it, and to convince the market that this advantage will last,” industry sources say.
For Spanish founders, the lesson is direct: the war for talent is not exclusive to Silicon Valley. Startups like Factorial, TravelPerk, or Wallbox have built their competitive advantage by aggressively hiring hard-to-replace profiles and transparently communicating their purpose to investors. It’s not necessary to raise €30 billion: it’s enough to understand that each round of business angels or seed series should also be read as a vote of confidence in who is executing.
“Investor confidence is built with execution and coherent narrative. Anthropic has sold a vision of responsible AI and executed it with product milestones and agreements with hyperscalers. In a sector where hype is commonplace, consistency pays off,” explain sources from a venture capital firm that participated in the round.
What it means for the Spanish entrepreneurial ecosystem
The case of Anthropic is not an isolated phenomenon. The entire artificial intelligence ecosystem is experiencing a concentration of capital reminiscent of the early years of the internet. Funds are not investing in products: they are buying teams and narratives. The valuation of Dario Amodei's startup reflects that the market pays for the expectation that the right team, with the right philosophy, will be the one to win when generative AI becomes basic infrastructure for the entire economy.
For Spanish entrepreneurs, the message is clear: the ability to attract talent and build a coherent story is as important as technology. In an environment where funding rounds are multiplying, execution and transparency make the difference. Anthropic has demonstrated that, even starting from scratch and competing against a giant, one can reach the top if the right team and strategy are in place.
The company expects to continue scaling its infrastructure and expanding Claude's reach in the coming months. Investors are confident that the demand for generative AI will only continue to grow, and Anthropic is well-positioned to capture a significant share of that market. The next stop: profitability, which according to company sources could arrive in 2027 if the current revenue growth pace is maintained.
