SAN FRANCISCO — Anthropic, an artificial intelligence company, announced on Thursday that it successfully raised $65 billion in private funding, propelling its valuation to a staggering $965 billion. This remarkable number positions Anthropic, the developer of the Claude chatbot, as one of the world’s most valuable startups as it approaches a likely debut on Wall Street.

The announcement significantly boosts Anthropic ahead of its principal competitor, OpenAI, known for its ChatGPT technology, in both market capitalization and reported revenue streams. Anthropic noted that its current annualized revenue stands at $47 billion, largely driven by its technology’s application in helping users write code and perform various tasks more efficiently.

Founded in 2021 by former leaders from OpenAI, Anthropic and OpenAI, alongside SpaceX, are all anticipated to become publicly traded entities. Notably, each of these firms is currently navigating financial losses, which raises concerns about a looming artificial intelligence bubble.

The funding round, led by prominent investment firms including Altimeter Capital and Sequoia Capital, is expected to enhance Anthropic’s ability to meet the unprecedented demand for its services, maintain its edge in research, and further distribute Claude’s capabilities to various workplaces. Chief Financial Officer Krishna Rao emphasized in a statement that this financing allows Anthropic to keep pace with the growing user base and technology advancements.

In conjunction with this funding announcement, Anthropic unveiled its latest AI model, Claude Opus 4.8, which claims to exhibit superior performance in coding and professional applications compared to its predecessors. This development reflects Anthropic’s swift rise and the increasing popularity of Claude, leaving OpenAI in a position where it must accelerate its offerings despite having established ChatGPT as a household name and igniting a commercial AI boom.

OpenAI’s last reported valuation in March was $852 billion, following a $122 billion fundraise. SpaceX, valued at $800 billion last year, saw its valuation leap to $1.25 trillion after merging with Musk’s xAI in February. Meanwhile, Elon Musk is expected to conduct one of the largest stock sales in history, with plans to pitch this offering to investors soon.

Despite its soaring success, Anthropic has faced hurdles this year, notably a contentious legal battle with the Trump administration regarding the use of AI tools like Claude in warfare. President Trump ordered federal agencies to halt using Claude, citing supply chain risks as articulated by Defense Secretary Pete Hegseth. Subsequently, Anthropic responded by filing a lawsuit, which is ongoing in federal courts.

In addition to its legal challenges, Anthropic has been engaging with the White House concerning the cybersecurity threats and capabilities associated with its powerful AI model, Mythos, which is not yet extensively available. Anthropic’s influence also extended to the Vatican, where it played a role preceding Pope Leo XIV’s call for stringent AI regulations to ensure development aligns with the common good rather than profit. This call for action was highlighted in Leo’s inaugural encyclical, “Magnifica Humanitas,” emphasizing the risks of data and power concentration within a select few private entities.
