Anthropic IPO: AI Giant Files for Trillion-Dollar Listing

Anthropic has confidentially filed a draft S-1 with the US Securities and Exchange Commission. This moves the Claude-maker closer to a public listing this fall. What's interesting is that investors expect the company's valuation to comfortably clear $1 trillion. This filing comes after Anthropic closed a $65 billion Series H round at a $965 billion post-money valuation, surpassing OpenAI. The company's annualized revenue grew from $9 billion at the end of 2025 to $47 billion last month. This growth has impacted markets. A successful listing would place Anthropic in a three-way IPO race with OpenAI and Elon Musk's SpaceX. The bottom line: This development shows a significant step for a major AI company towards public ownership.
