Anthropic has emerged as the world's most valuable artificial intelligence startup after securing a $65 billion Series H funding round that pushed its post-money valuation to $965 billion, overtaking rival OpenAI in the rapidly expanding AI market.
The funding round marks one of the largest private fundraising events in technology history and reflects growing investor confidence in AI companies that are building large-scale enterprise and consumer applications. The latest valuation places Anthropic ahead of OpenAI, which was most recently valued at $852 billion following its funding activities earlier this year.
The round was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital, alongside previously committed investments from major technology partners. The financing includes $15 billion in earlier commitments from hyperscale cloud providers, including a reported $5 billion investment from Amazon.
Anthropic said the new capital will be used to expand its research efforts, strengthen computing infrastructure and support wider deployment of its AI products. The company has seen strong demand for Claude, its family of large language models, which are increasingly being adopted by enterprises for productivity, coding, workflow automation and customer-facing applications.
Founded in 2021 by former OpenAI executives Dario Amodei and Daniela Amodei, Anthropic has positioned itself as a major competitor in the global AI race while maintaining a strong focus on AI safety and responsible development. Over the last two years, the company has attracted substantial backing from technology giants including Amazon and Google, both of which have invested billions of dollars into the startup.
Anthropic's valuation growth has accelerated sharply in recent months. The company was valued at $380 billion during a funding round announced in February 2026. The latest fundraising nearly triples that figure, underlining the pace at which investor enthusiasm for AI companies continues to rise.
Industry analysts point to the increasing enterprise adoption of generative AI as a key driver behind the surge in valuations across the sector. Businesses are moving beyond experimentation and are beginning to integrate AI tools into everyday operations, creating new revenue opportunities for model developers and infrastructure providers.
Anthropic has also expanded its product portfolio through Claude Code, an AI-powered coding assistant that has gained traction among software developers and enterprise technology teams. The company has released multiple upgraded AI models over the past year as competition intensifies among leading AI developers.
The broader AI sector has witnessed an unprecedented wave of investment over the past 18 months. OpenAI, Anthropic, Google-backed ventures and Elon Musk's AI initiatives have all attracted significant funding as investors seek exposure to technologies expected to transform industries ranging from software development and customer service to healthcare and financial services.
Despite strong investor optimism, the sector continues to face questions around profitability, infrastructure costs and long-term sustainability. AI companies are spending heavily on computing power, semiconductor resources and research talent to maintain their competitive positions. Industry observers note that future growth will depend not only on model performance but also on the ability to generate sustainable business returns.
Anthropic's latest milestone signals a shift in the competitive landscape of the AI industry, where leadership is increasingly being measured by enterprise adoption, revenue growth and investor backing. As the race for AI dominance continues, the company's new valuation highlights the scale of capital flowing into the sector and the growing importance of AI in shaping the future of global technology markets.
