Anthropic Hits $965 Billion Valuation Ahead of 2026 IPO
Anthropic's valuation soared to $965 billion in 2026 after massive funding rounds, with the AI company confidentially filing for a U.S. IPO in June.
Anthropic raised $30 billion in February 2026, more than doubling its valuation to $380 billion. In May 2026, the company announced a $65 billion funding round at a $965 billion post-money valuation. This trajectory, from a $124 million funding round in 2021 to a near-trillion dollar valuation in five years, highlights the unprecedented speed of frontier AI industry development. The company, founded by siblings Dario Amodei and Daniela Amodei, confidentially filed for a U.S. IPO in June 2026.
Strategic partnerships and revenue acceleration
Major investments from Amazon and a landmark cloud deal with Akamai have driven explosive revenue growth. Amazon committed up to $4 billion in September 2023 and an additional $4 billion in November 2024. Google agreed to invest up to $2 billion in October 2023. In September 2026, Anthropic secured an $11.6 billion cloud services agreement with Akamai over seven years. That agreement could expand by a further $9 billion and includes a warrant for up to a 5% stake in Akamai.
The company's annual revenue run rate surpassed $65 billion by the end of July 2026. This was up from $47 billion in May and just $9 billion at the end of 2025. Anthropic has forecast revenue of roughly $190 billion to $200 billion for 2028.

Legal and regulatory challenges
Anthropic faces significant legal and regulatory headwinds alongside its commercial success. A federal judge in San Francisco approved a $1.5 billion settlement in July 2026 involving authors who accused Anthropic of misusing their books to train its AI system. Round Hill Music sued Anthropic and Suno in August 2026 in California federal court, alleging improper use of songs to train AI systems. Three authors had also filed a class-action lawsuit against Anthropic in August 2024 over alleged misuse of copyrighted books for training Claude.
On the regulatory front, Anthropic sued to block the Pentagon from placing it on a national security blacklist in March 2026. In February 2026, President Donald Trump directed the government to stop work with Anthropic, and the Pentagon designated it a supply-chain risk. That same month, the company unveiled Mythos, described as its most advanced model for defensive cybersecurity applications.
The company's IPO prospectus presents an ambitious view of AI's potential economic impact, suggesting it could reshape the global economy on a scale exceeding previous technological transformations. Reuters reported Anthropic was discussing an IPO that could raise up to $100 billion at a valuation of around $2 trillion, with Nvidia considering a potential investment of up to $10 billion. The company is pursuing a corporate structure where its seven co-founders would collectively control 50.1% of voting power through special class shares.
