(Bloomberg) — Anthropic PBC has received several offers from investors for a new round of funding that could value the artificial intelligence startup at about $800 billion or higher — overtures that the Claude maker has so far resisted, according to people familiar with the matter.

The offers would more than double the $350 billion pre-money valuation Anthropic attached to its $30 billion fundraising in February. While Anthropic hasn’t ruled out raising new money in the coming months, according to one of the people, it’s not clear the company will accept investors’ terms or if it will raise at an $800 billion value.

Earlier this month, Anthropic completed a tender offer at the same value of the February fundraising, but current and former employees wanted to hold onto more of their shares ahead of ahead of a possible public listing as soon as October.

Anthropic declined to comment.

The investor interest highlights the increasing buzz around one of Silicon Valley’s most high-profile startups. Led by co-founder Dario Amodei, Anthropic has dominated tech news recently, between a dustup with the Pentagon over how its technology is used by the military to the release last week of its latest AI model, Mythos, which is so powerful at finding vulnerabilities in software that the company deemed it too dangerous for wide release.

Anthropic has developed a series of AI tools aimed at overhauling the way companies handle tasks from coding to cybersecurity. Those products are resonating with a growing base of business customers, leading to a jump in revenue and raising competition with rival OpenAI.

Investors have been impressed by Anthropic’s strong revenue growth, particularly with deep-pocketed enterprise customers. Earlier this month, the startup said it had reached $30 billion in annual run-rate revenue, marking a sharp increase from $19 billion just a few months before.

OpenAI said about two weeks ago that it’s currently generating $2 billion in revenue each month. OpenAI Chief Financial Officer Sarah Friar had earlier said the company’s annualized revenue topped $20 billion in 2025, up from roughly $6 billion the year prior. The company recently completed a deal to raise $122 billion from investors at an $852 billion valuation.

Talks between Anthropic and investors are early, and a deal could fail to materialize or the details could change, the people familiar with the matter said, asking not to be identified because the information is private. Business Insider previously reported some details of the talks.
