Key Takeaways

• Anthropic has reportedly secured a $30 billion funding round, valuing the company at approximately $900 billion.

• The company’s valuation has nearly tripled from $380 billion in just the last three months.
• Annualized revenue is projected to exceed $45 billion shortly, marking a fivefold increase in less than half a year.
• Dragoneer, Greenoaks, Sequoia Capital, and Altimeter Capital are co-leading this investment round.

(SeaPRwire) –   Anthropic is nearing a $900 billion valuation, having reportedly agreed to terms for a new $30 billion funding round, as reported by the Financial Times. While not yet officially announced, the transaction is anticipated to finalize this month.

Anthropic is raising $30 billion at a $900 billion valuation, a near triple from its $350 billion valuation just 3 months ago with the round co-led by Dragoneer, Greenoaks, Sequoia, and Altimeter.

This funding round would assign Anthropic an approximate pre-money valuation of $900 billion. Such a valuation would propel the company beyond OpenAI, whose most recent appraisal stood at about $852 billion.

Just three months prior, after its Series G round, Anthropic was valued at $380 billion. Achieving a valuation increase from $380 billion to $900 billion within a single quarter represents an unprecedented growth rate for most private enterprises.

The funding round materialized rapidly. Investors initiated contact with Anthropic last month, prompting CFO Krishna Rao to assess market interest. The entire process concluded within a matter of weeks.

The round is being co-led by four prominent firms: Dragoneer Investment Group, Greenoaks Capital, Sequoia Capital, and Altimeter Capital, with each anticipated to contribute a minimum of $2 billion. Anthropic is also reportedly engaging with further investors to complete the funding.

Valuation Boosted by Revenue Surge

This significant increase in valuation is directly attributable to the company’s revenue expansion. Anthropic’s annualized revenue was approximately $9 billion at the close of 2025. By April 2026, this figure had climbed to over $30 billion, and the company now anticipates it will soon exceed $45 billion.

This represents a fivefold growth in under half a year. Furthermore, it would position Anthropic’s revenue run rate ahead of OpenAI’s reported $24 billion annual figure for the first time.

The primary catalyst for this growth is the increasing enterprise adoption of Claude, Anthropic’s suite of AI assistants and models. Businesses are rapidly onboarding, contributing to the accelerated revenue.

For the better part of the last two years, Anthropic was often perceived as a more subdued, developer-centric alternative to OpenAI. This characterization is becoming increasingly difficult to maintain.

Implications for the AI Competitive Landscape

The rapid execution of this fundraise underscores the intense investor interest and swift pace within the artificial intelligence sector. The agreement was finalized in weeks, rather than months.

Anthropic concluded its preceding $30 billion Series G round in February 2026, achieving a post-money valuation of $380 billion. At the time, the company stated these funds would be allocated to frontier research, product innovation, and infrastructure development.

Remarkably, only a quarter later, the company is securing additional capital at more than twice that previous valuation.

As the new round has not been formally disclosed, its terms remain subject to potential adjustments prior to its finalization.

Should the deal conclude at the stipulated valuation, Anthropic would ascend to the pinnacle of private AI company valuations, surpassing OpenAI for the inaugural time.

The company’s trajectory has been exceptionally rapid. The critical question of whether its revenue growth can sustain this elevated valuation is one that investors are evidently confident in.
