Anthropic Overtakes OpenAI with a $965 Billion Valuation, Turning Up the Heat in the AI Race

Anthropic has closed a new $65 billion funding round at a $965 billion valuation—pushing the Claude maker past rival OpenAI, which was valued at roughly $852 billion in March.

According to CNBC, the deal ranks among the largest private tech investments ever. The new valuation nudges Anthropic strikingly close to the $1 trillion threshold—territory that, until recently, was mostly reserved for publicly traded tech giants.

Now it’s a waiting game to see when OpenAI raises its next war chest.

The surge in value is driven by explosive revenue growth. Anthropic says its annualized revenue run rate has hit $47 billion—up from around $30 billion in early 2026 and roughly $10 billion at the end of 2025.

Enterprise demand is the rocket fuel. Claude Code, Anthropic’s developer assistant, is a key engine as companies increasingly use it for software development, automation, and technical support.

The momentum shows generative AI is moving from experimental tool to core business infrastructure.

The round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital. About $15 billion of previously committed capital is included in the total.

Amazon remains pivotal. The cloud giant has invested billions in Anthropic and is now one of its most important strategic partners.

For Amazon, Anthropic is more than a bet. Claude largely runs on Amazon Web Services (AWS), binding the companies even closer together.

Alongside the funding news, Anthropic unveiled its latest model: Claude Opus 4.8.

The model targets advanced coding, complex reasoning, and knowledge work. Anthropic says Opus 4.8 is more reliable than prior generations and handles uncertainty in answers more effectively.

A standout feature: finer-grained control over compute usage. That lets businesses rein in costs while keeping access to high-end AI capabilities.

It’s a compelling pitch as more companies grapple with the rising operating costs of generative AI.

Beyond Opus 4.8, Anthropic is building what could be an even bigger long-term driver.

Claude Mythos Preview is an advanced AI system with strong cybersecurity capabilities, currently limited to select organizations.

Anthropic is deliberately rolling it out slowly over misuse concerns—true to its reputation as a lab that prioritizes safety and responsible deployment.

Investors are intrigued because cybersecurity is seen as one of AI’s largest future growth markets.

The round highlights shifting power dynamics across AI.

Microsoft has built dominance through OpenAI, but a second power center is emerging around Amazon and Anthropic. Meanwhile, Google is pouring billions into Gemini, and Elon Musk is building his own AI stack via xAI.

The contest now spans models, cloud infrastructure, data centers, chips, and enterprise distribution.

No wonder more analysts are calling it an AI arms race among the world’s largest tech companies.

The timing stands out. U.S. media report that both OpenAI and Anthropic are preparing for potential public listings.

OpenAI could confidentially file for an IPO as soon as later this year. Anthropic, according to prior reporting, is exploring multiple paths to the public markets as well.

If either proceeds, investors would, for the first time, get direct exposure to some of the most influential AI companies on the planet.

A $965 billion valuation signals how strongly investors believe in AI’s economic impact.

What was once a promising technology is now viewed by many businesses as essential infrastructure for software development, customer service, cybersecurity, research, and knowledge work.

But the pressure is on to justify these lofty numbers. The next few years will show whether companies like Anthropic can keep up their blistering growth as competition intensifies.

For now, one thing is clear: Anthropic has overtaken OpenAI in valuation and is staking its claim as one of the most powerful players in global AI.
