According to Bloomberg, Anthropic is in the final stages of securing $20 billion in new capital, reaching a valuation of $350 billion. The report indicates that due to robust investor demand, the amount raised is double the company's initial target. This urgency for more funding comes just five months after Anthropic raised $13 billion in equity, driven by intense competition among frontier AI labs and the ongoing high costs of computing resources.

Participants in this funding round are expected to include Altimeter Capital Management, Sequoia Capital, Lightspeed Venture Partners, Menlo Ventures, Coatue Management, Iconiq Capital, and Singapore's sovereign wealth fund. However, it is reported that the majority of the capital is coming from the company's strategic partners, Nvidia and Microsoft.

Anthropic is capitalizing on its recent successes, particularly the deployment of its coding agent, which has drawn praise from software engineers for significantly boosting coding productivity. Last week, the company released a new model focused on legal and business research, a move that rattled the stock prices of publicly-traded data companies as investors grew concerned about AI's potential to disrupt their core businesses.

Reports suggest that Anthropic's rival, OpenAI, is also in the process of raising a new $100 billion funding round. Both companies are widely believed to be preparing for a blockbuster IPO this summer. Meanwhile, xAI, recently acquired by SpaceX, is also leveraging public equity as part of the rocket manufacturer's own impending IPO.
