Just now, Anthropic secured $13 billion in financing amidst doubts, with a valuation reaching $183 billion.

Anthropic announced that it has completed a new round of financing of $13 billion, with a post - investment valuation of $183 billion, approximately three times that of the last financing round in March for this artificial intelligence startup.

This is also the second - largest private equity financing in the technology industry to date, second only to OpenAI's historic $40 billion financing in March 2025.

This latest round of financing is Anthropic's Series F financing, led by Iconiq, Fidelity Management & Research Co., and Lightspeed Venture Partners. Anthropic said that other investors, including Altimeter, General Catalyst, and Coatue, also participated.

Anthropic's Chief Financial Officer Krishna Rao said in a statement: "This financing shows investors' great confidence in our financial performance and demonstrates their commitment to partnering with us, which will continue to drive our unprecedented growth."

Since the launch of its AI assistant Claude in March 2023, Anthropic's valuation has soared.

At the beginning of 2025, less than two years after the launch of Claude, Anthropic's operating revenue had grown to approximately $1 billion. By August 2025 — just eight months later, the company's run - rate revenue exceeded $5 billion, making Anthropic one of the fastest - growing technology companies in history.

In addition, the company also highlighted Claude Code in its statement: "For enterprises, our API and industry - specific products enable them to easily add powerful AI to their critical applications without complex integration work. Since its full release in May 2025, Claude Code has become the preferred tool for developers. Claude Code has developed rapidly, generating over $500 million in operating revenue, and its usage has increased by more than 10 times in just three months."

The dynamic statistical chart released by Vibe Kanban also confirms its advantages. However, it can also be seen that Codex Cli, a competitor launched by OpenAI, has shown significant growth.

Anthropic said that it has served more than 300,000 enterprise customers, and the number of its large customers (each with operating revenue of over $100,000) has increased by nearly 7 times in the past year.

Anthropic also said that it will use the new capital to deepen security research, meet the growing enterprise demand, and support international expansion.

Behind the high valuation, Anthropic has also sparked a lot of controversies recently:

Default collection of user data for training (consumer side): Anthropic announced that it will use users' chat and coding sessions for model training unless users actively opt out; at the same time, it will retain the data allowed for training for up to 5 years (30 days for those who do not allow). This change covers Claude Free/Pro/Max and Claude Code, but does not apply to enterprise/government/education or API (Bedrock/Vertex) scenarios. It also set a deadline of September 28, 2025, and a pop - up window with a default "Accept" design, which has sparked controversy.

Tightening of "usage limits" affects heavy users. Since the end of July, Anthropic has introduced a weekly usage cap for Pro/Max users (especially heavy users of Claude Code) and a new quota method measured by the hour (reset every 5 hours); the official said that it only affects < 5% of subscribers, but there has been a significant backlash in the community.

Community controversy over model experience fluctuations. With the launch of new models/snapshots, some users reported that the performance of top - tier models has declined periodically (dumbed down), and that the performance of previous models was suppressed for the release of new models. Related complaints have continued to ferment in the community (although it is a subjective experience, the discussion is intense).

The setting of "self - protection/ending the conversation" for the model has also sparked discussions. Anthropic said that the latest large - scale models can actively end the conversation in extreme and continuous abuse/harmful scenarios, which has been questioned by some users as "putting AI before users".

Multiple copyright/data litigation fronts: Author cases, music publishing cases, and Reddit lawsuits.

However, it seems that these controversies have not had a significant impact on investors' confidence in Anthropic.

Anthropic was founded by several former OpenAI research executives, including CEO Dario Amodei. Nowadays, OpenAI and Anthropic have become fierce competitors in the AI market.

OpenAI quickly became mainstream after releasing the AI chatbot ChatGPT in 2022. It is reported that OpenAI is preparing to sell stocks as part of a secondary sale, which will value the company at approximately $500 billion. Today, OpenAI also announced the acquisition of the product analytics startup Statsig for $1.1 billion and appointed its CEO Vijaye Raji as OpenAI's product CTO, reporting to the application CEO Fidji Simo.
