Anthropic has announced that it raised $3.5 billion, with a post-money valuation of $61.5 billion. This funding round was led by Lightspeed Venture Partners, with participation from Bessemer Venture Partners, Cisco Investments, D1 Capital Partners, Fidelity Management & Research Company, General Catalyst, Jane Street, Menlo Ventures, and Salesforce Ventures. This brings the company’s total funding to $18.2 billion.
In a blog post, the company stated that this investment will accelerate the development of next-generation artificial intelligence systems, expand computational power, deepen research in mechanistic interpretability and alignment, and accelerate its international expansion.
Anthropic’s latest AI model, Claude 3.7 Sonnet, is part of the company's efforts to simplify the product experience. This model is a “hybrid reasoning” model capable of carefully considering user queries before responding. Anthropic aims to eliminate the need for users to choose between multiple AI options with varying costs and capabilities—ideally, one model will handle everything.
The company has already seen revenue growth, with a reported 30% increase in annual revenue in 2025. However, it is spending heavily on developing its AI systems, with an expected burn rate of around $3 billion this year.
Anthropic has also begun offering new tools and subscription plans, including "agents" for computer use, a desktop client, and mobile applications. The company has opened offices in Europe and made several high-profile hires, including Instagram co-founder Mike Krieger, OpenAI co-founder Durk Kingma, and former OpenAI safety researcher Jan Leike.
The company has strengthened its relationship with Amazon, which invested an additional $4 billion in Anthropic. Amazon will collaborate with the company to optimize its custom AI chips, Trainium, for model training workloads. Together, they are also working on Alexa's new version, Alexa+.
Anthropic was founded in 2021 by CEO Dario Amodei, who previously served as VP of Research at OpenAI but parted ways with the company over differences in future plans. Amodei, along with several former OpenAI employees, launched Anthropic, including former OpenAI policy lead Jack Clark.
Anthropic positions itself as more safety-focused than OpenAI.
