Anthropic Raises $3.5 Billion at $61.5 Billion Valuation

AI startup Anthropic announced on Monday that it secured $3.5 billion in a Series E funding round, bringing its post-money valuation to $61.5 billion. The investment was led by Lightspeed Venture Partners, with contributions from Bessemer Venture Partners, Cisco Investments, D1 Capital Partners, Fidelity Management & Research Company, General Catalyst, Jane Street, Menlo Ventures, and Salesforce Ventures, among others.

The company plans to use the funds to advance AI research, expand compute capacity, and accelerate international growth. “With this investment, Anthropic will advance its development of next-generation AI systems, expand its compute capacity, deepen its research in mechanistic interpretability and alignment, and accelerate its international expansion,” the company stated.

In November 2024, the AI startup secured $4 billion from Amazon Web Services (AWS). With the latest funding, its total now stands at $18.2 billion, according to Crunchbase.

The announcement follows the release of Claude 3.7 Sonnet and Claude Code. “Claude 3.7 Sonnet has set a new high-water mark in coding abilities—an area where Anthropic plans to make further progress in the coming months,” the company said.

The company said that businesses across sectors are integrating Anthropic’s AI into their workflows. Replit uses Claude in its “Agent” tool to generate code from natural language and reported a 10X revenue increase. Thomson Reuters’ CoCounsel platform leverages Claude for tax assistance, while Novo Nordisk has reduced clinical study report writing time from 12 weeks to 10 minutes using Claude.

Recently, Amazon announced that Alexa+ is powered by Anthropic models, expanding its capabilities for Prime members.

The company said that it remains focused on AI research and safety. “We are committed to deepening our understanding of frontier AI systems and ensuring artificial intelligence serves human progress,”  the company stated.
