Anthropic, maker of the Claude AI assistant, confidentially filed for an IPO with regulators on June 1 and is approaching a trillion-dollar valuation in private markets. Three early investors—Alphabet, Amazon, and Zoom Communications—are positioned to see major gains when the company goes public.
Why it matters
Alphabet holds a 14% stake in Anthropic valued at about $135.1 billion（約22兆円） at a $965 billion（約150兆円） private-market valuation; Amazon's combined Anthropic preferred stock and convertible notes are worth $74.2 billion（約12兆円） as of its first-quarter results; and Zoom's initial investment has grown to almost $1.3 billion（約2100億円）. These windfalls reflect how strategic AI bets by large tech companies have compounded in value as the sector has matured.
What to watch
Alphabet's total Anthropic investments include $300 million（約480億円） in April 2023, $2 billion（約3200億円） in October 2023, and $40 billion（約6.4兆円） in April 2026 (with $10 billion（約1.6兆円） upfront and $30 billion（約4.8兆円） dependent on performance milestones). Amazon's stack includes $1.25 billion（約2000億円） in September 2023, $2.75 billion（約4400億円） in March 2024, $4 billion（約6400億円） in November 2024, and $25 billion（約4兆円） in April 2026 in return for Anthropic spending more than $100 billion（約16兆円） on AWS technologies over the next decade.
Anthropic's confidential IPO filing marks a milestone for the AI sector, bringing one of the largest independent AI companies to public markets. The company's approach of $965 billion（約150兆円） valuation in private markets reflects how central large language models have become to corporate strategy. Alphabet, Amazon, and Zoom are not passive shareholders—they have built strategic relationships into their investments, with Amazon tying a $25 billion（約4兆円） commitment to future AWS spending by Anthropic, signaling how cloud infrastructure providers view AI as foundational to their competitive position.
Alphabet's portfolio of AI bets extends beyond Anthropic: the article notes its $900 million（約1400億円） investment in SpaceX in 2015 is now worth approximately $104.6 billion（約17兆円）, and its 75% stake in Waymo (valued at roughly $95 billion（約15兆円） at a $126 billion（約20兆円） valuation) demonstrates a long track record of early-stage AI and automation bets. Amazon's early bet of $1.25 billion（約2000億円） in September 2023 has compounded to a position worth $74.2 billion（約12兆円） in less than two years—a more than ninefold return on the initial deployment. For Zoom, an investment made through its venture arm during the Series C round in May 2023 has similarly appreciated to almost $1.3 billion（約2100億円）. These returns suggest that for large tech companies with capital and strategic vision, early exposure to leading AI models has proven highly lucrative.
