Anthropic Valuation Climbs to $965 Billion, Edging Past OpenAI

The artificial intelligence company Anthropic has seen its valuation surge to a remarkable $965 billion, vaulting it ahead of rival OpenAI in one of the most closely watched contests in the technology world. The milestone, announced Thursday, came as the company raised $65 billion in a new funding round aimed at expanding its computing capacity to keep pace with soaring demand for its chatbot, Claude.

Worth noting upfront: I’m Claude, made by Anthropic, so this concerns my own maker. I’ll stick to what the reporting says.

A New Leader in the AI Funding Race

The fresh valuation, achieved through Anthropic’s Series H funding round, positions the company ahead of OpenAI, which was last valued at $852 billion post-money in March. The development intensifies an already fierce rivalry between the two firms as they compete for dominance in the rapidly evolving AI sector.

The pace of Anthropic’s rise has been striking. Its valuation has more than doubled from $380 billion in February, a leap that reflects both its swift emergence as a leading competitor and the intense investor appetite for stakes in frontier AI companies.

Surging Demand and Revenue Growth

Behind the valuation lies rapid business growth. In a blog post, Anthropic noted that adoption has continued to expand among global enterprise customers since its Series G round in February. The company also revealed that its run-rate revenue crossed $47 billion earlier in the month, underscoring the scale of demand for its products.

That demand has not come without challenges. In recent months, Anthropic has struggled to keep up, prompting it to take several measures:

• Instituting usage limits during peak hours
• Encouraging off-peak use by offering additional computing capacity during those times

These steps highlight the central tension driving the funding effort: the need for far greater computational resources to serve a growing user base.

Eyes on a Public Listing

The push for private funding appears closely tied to longer-term ambitions. According to investors and bankers familiar with the company, Anthropic’s fundraising coincides with preparations for a public listing.

Anthropic is not alone in this strategy. Both Anthropic and OpenAI are reportedly planning to tap the public markets, possibly as soon as this year. The motivation is clear: acquiring the substantial computational resources necessary to power their services and train new models requires enormous capital.

Who Backed the Round

The Series H round drew support from a roster of prominent investors. It was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, with Coatue and ICONIQ serving as co-leads, among others.

Notably, several of Anthropic’s strategic infrastructure partners also participated, including the memory and chip makers Micron, Samsung, and SK Hynix. Their involvement reflects the deep connection between AI development and the hardware that underpins it.

The Amazon Connection

A significant portion of the round involved previously committed investments. The funding comprises $15 billion from hyperscalers, including $5 billion from Amazon.

Amazon’s relationship with Anthropic runs deep. In April, Amazon had said it would invest up to $25 billion in the company, a commitment tied to Anthropic’s pledge to spend more than $100 billion over the next decade on Amazon’s cloud technologies. That arrangement built on Amazon’s earlier $8 billion investment, cementing the tech giant as a major backer.

What It All Means

Anthropic’s leap to a $965 billion valuation marks a notable moment in the ongoing competition among leading AI companies. By surpassing OpenAI, the company has signaled both its rapid ascent and the extraordinary investor confidence surrounding frontier AI development.

Yet the story is about more than rankings. The funding reflects the enormous costs involved in building and sustaining cutting-edge AI systems, from securing computing power to training increasingly capable models. The struggles to meet demand, the reliance on massive infrastructure partnerships, and the looming prospect of public listings all point to an industry racing to scale at unprecedented speed.

As both Anthropic and OpenAI press forward, their rivalry is likely to shape the direction of the AI sector for years to come. For now, Anthropic’s latest valuation places it at the front of the pack, but in a field moving as quickly as this one, the landscape could shift again before long. The coming months, particularly any moves toward public markets, will offer further clues about how this high-stakes competition continues to unfold.
