3 Key Points

What happened
Anthropic, maker of the Claude AI model, filed a confidential IPO application with the Securities and Exchange Commission on June 1. The company's most recent funding round valued it at $965 billion（約150兆円）, and it reported an annual run rate of $47 billion（約7.5兆円） in revenue at that time.
Why it matters
Anthropic is one of the two major independent AI companies (the other being OpenAI), and its revenue substantially exceeds that of SpaceX—which generated just over $20 billion（約3.2兆円） in 2025 revenue—despite being valued at about half SpaceX's size. For investors, this suggests the company may offer significant upside when it goes public.
What to watch
If Anthropic follows a timeline similar to SpaceX's confidential IPO process, the company could go public in early fall. The company will likely list at a valuation greater than $1 trillion（約160兆円）. Until then, investors can gain exposure through Amazon or Alphabet, both of which own a significant stake in Anthropic.
