Anthropic Raises More Than Planned as Investor Demand Surges

Artificial intelligence startup Anthropic has officially closed its latest funding round above its original $10 billion target, pushing the company’s valuation to approximately $350 billion, according to people familiar with the matter.

Sources say the round ultimately landed somewhere between $10 billion and $15 billion, making it one of the largest private financings in tech history. The final figure could increase even further if Microsoft and Nvidia decide to participate, discussions that remain ongoing behind the scenes.

The fundraising comes amid intense global competition for exposure to leading AI platforms, with institutional investors and technology giants racing to secure strategic stakes in companies building foundational models.

Microsoft and Nvidia Could Still Add Billions

Microsoft and Nvidia previously announced intentions in November to invest up to $5 billion and up to $10 billion, respectively, into Anthropic. While neither company has confirmed participation in this specific round yet, sources indicate both remain in active talks and could still commit capital.

If either or both companies join, Anthropic’s total raise could move meaningfully higher, potentially placing the round closer to the upper end of the $15 billion range or beyond.

Such participation would further deepen Anthropic’s ties with major cloud and semiconductor players, strengthening its access to compute infrastructure, advanced GPUs, and enterprise distribution channels critical for scaling large language models.

Coatue and GIC Lead a High-Profile Investor Group

The financing is being led by Coatue Management alongside Singapore’s sovereign wealth fund GIC, highlighting growing international interest in U.S.-based AI innovation. Sequoia Capital is also participating, despite being a long-standing investor in Anthropic rival OpenAI, signaling broad-based conviction across the venture capital ecosystem.

The round was reportedly oversubscribed, reflecting overwhelming demand from both financial and strategic investors eager to gain exposure to Anthropic’s rapid growth and expanding product lineup.

The size and valuation of the raise place Anthropic among the most valuable private companies globally, alongside firms such as SpaceX and ByteDance.

From OpenAI Roots to Claude’s Rapid Rise

Anthropic was founded in 2021 by former OpenAI research executives, including CEO Dario Amodei, with a mission focused on building safer, more reliable artificial intelligence systems.

The company is best known for its Claude family of large language models, which compete directly with OpenAI’s ChatGPT and Google’s Gemini. In recent months, Anthropic has also seen explosive adoption of Claude Code, its AI-powered coding assistant, which has gained traction among software developers and enterprise teams seeking productivity gains.

Anthropic’s models are now integrated across multiple platforms and cloud environments, supporting use cases ranging from customer service automation and document analysis to advanced software development.

Revenue Nears $10 Billion as Commercial Adoption Accelerates

Amodei recently told CNBC that Anthropic generated close to $10 billion in revenue last year, a striking figure for a company founded just four years ago. That growth has been fueled by enterprise subscriptions, developer usage, and expanding partnerships with major technology providers.

Industry analysts note that Anthropic’s revenue trajectory places it among the fastest-scaling AI companies in history, driven by surging demand for generative AI tools across finance, healthcare, retail, and software engineering.

With operating costs rising due to massive compute requirements, the new capital injection is expected to fund further model development, global expansion, hiring, and long-term infrastructure investments.

A Landmark Deal in the Global AI Funding Race

Anthropic’s latest raise reflects a broader investment boom in artificial intelligence, as companies and governments pour unprecedented resources into foundational models and AI infrastructure. In 2025 alone, global AI funding is on track to exceed $150 billion, with hyperscalers and sovereign funds playing an increasingly prominent role.

For Anthropic, the combination of a $350 billion valuation, multi-billion-dollar backing, and accelerating revenue solidifies its position as a central player in the AI arms race. As competition intensifies among OpenAI, Google, Meta, and emerging startups, Anthropic’s expanded war chest gives it significant firepower to push innovation while scaling its commercial footprint worldwide.
