US AI company Anthropic is set to raise far more money than initially planned. According to reports, the AI company has increased its latest fundraising target from $10 billion to $20 billion, driven by strong investor interest.
People familiar with the matter say the round is expected to close soon and would value Anthropic at around $350 billion, placing it among the most valuable private technology companies in the world.
Anthropic is best known for building Claude, its AI assistant, and Claude Code, a widely used tool for developers. The company’s growing influence in enterprise and developer-focused AI is said to be a key reason behind the jump in investor appetite.
The funding round is expected to include major backers such as Sequoia Capital, Singapore’s sovereign wealth fund, and investment firm Coatue, according to the report.
Last year, Anthropic was also reported to have hired legal advisers as part of early preparations for a potential IPO, which could happen as soon as this year. In September, the company announced a $13 billion raise, valuing it at $183 billion.
If the latest round closes as expected, it would mark another major milestone for Anthropic as competition and investment in advanced AI continue to accelerate worldwide.
Making advanced AI systems safer
Anthropic, founded in 2021 by siblings Dario Amodei and Daniela Amodei, is a US-based artificial intelligence company headquartered in San Francisco. The company builds large language models under the Claude brand and focuses heavily on making advanced AI systems safer and more reliable before releasing them for public use.
Its work centres on understanding how powerful AI behaves at the edge of current technology and using those insights to deploy responsible products.
Anthropic was launched in 2021 by a group of former OpenAI employees. Among the founders are siblings Dario Amodei and Daniela Amodei, who currently serve as CEO and president.
The company has attracted significant backing from major tech players. In September 2023, Amazon said it would invest up to $4 billion in Anthropic, followed by a $2 billion commitment from Google a month later. As of late 2025, Anthropic is estimated to be valued at around $350 billion, reflecting its growing role in the global AI landscape.
