AI company Anthropic has officially overtaken OpenAI to become the world’s most valuable artificial intelligence startup after securing a massive $65 billion funding round that pushed its valuation to an extraordinary $965 billion.
The funding milestone marks one of the largest private technology investment rounds ever recorded and signals the growing global demand for advanced AI systems.
Anthropic, the company behind the Claude family of AI models, has rapidly emerged as one of the most influential players in the global AI race.
According to reports published on May 28, the new Series H funding round was led by major investment firms, including Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital. Strategic technology partners such as Amazon also participated in the round as competition intensifies among AI firms seeking dominance in enterprise AI, cloud infrastructure and generative AI services.
The latest investment places Anthropic ahead of OpenAI, which was previously valued at approximately $852 billion.
The dramatic rise highlights how quickly investor confidence in the AI sector continues to expand as businesses worldwide integrate AI into software development, automation, customer service and data analysis.
Anthropic said the new funding will support the expansion of its AI research, computing infrastructure and global product deployment.
The company has recently increased its partnerships with major technology firms, including Amazon, Google, Broadcom and SpaceX, to strengthen computing capacity for its fast-growing AI operations.
Founded in 2021 by former OpenAI researchers, including Dario Amodei and Daniela Amodei, Anthropic has positioned itself as a leading advocate for AI safety and responsible AI development.
Its Claude chatbot and coding-focused AI tools have gained strong traction among enterprise users, helping the company significantly increase revenue growth in recent months.
Reports indicate Anthropic’s annualised revenue run rate has surged sharply alongside growing enterprise adoption of its AI products.
Analysts say the company’s rapid expansion reflects increasing demand for AI coding assistants, large language models and automation tools across industries.
The funding announcement also reshapes the broader AI industry landscape as major companies continue investing billions into artificial intelligence infrastructure.
Investors are increasingly betting that AI will become one of the most transformative technologies of the decade, driving competition between firms such as Anthropic, OpenAI, Google, Meta and xAI.
Despite the excitement surrounding the valuation, industry experts continue to raise concerns about AI regulation, ethics and the enormous costs associated with training advanced AI models.
Anthropic has frequently promoted stronger AI governance frameworks and has publicly supported stricter oversight measures for powerful AI systems.
The company’s rapid rise could also accelerate speculation around a future public listing. Both Anthropic and OpenAI are widely expected to explore IPO opportunities as demand for capital and computing power continues to grow.
Anthropic’s near-trillion-dollar valuation represents a historic moment for the AI industry and underscores how artificial intelligence has become one of the most aggressively funded sectors in global technology.
