Anthropic — The AI IPO Positioned to Break SpaceX's Record
The biggest IPO currently expected to hit the market is from artificial intelligence company Anthropic. While SpaceX delivered the largest IPO in history this past June, Anthropic is now lining up to potentially eclipse it.
Backed by Amazon and Google, Anthropic has quietly become one of the most influential AI labs on the planet. Claude powers workflows inside Fortune 500 companies, government agencies and a growing slice of the developer ecosystem. When the S-1 lands, it could be the largest private-to-public transition ever attempted.

Why Anthropic Is Being Called the Next Big IPO
A reported October 2026 window, an over-$2 trillion target valuation and up to $100 billion in potential capital raised could put Anthropic ahead of every private-to-public debut on record.
SpaceX: $1.77T · June 2026
SpaceX completed its historic IPO on June 12, 2026 and is currently the largest debut on record. Anthropic's reported over-$2T target would make it the new benchmark.
OpenAI: Later, Less Certain
OpenAI has reportedly filed confidentially for an IPO but may not list until 2027. After raising significant private capital, it is not in a hurry — leaving Anthropic as the nearer-term AI mega-listing.
Claude, the flagship product
Anthropic's Claude family — Opus, Sonnet, Haiku — is the engine now embedded in Fortune 500 workflows, sovereign contracts and a fast-growing developer economy.

Founded by ex-OpenAI leadership
Dario and Daniela Amodei left OpenAI in 2021 to found Anthropic with a research bench that has since become one of the most decorated in the field. The IPO will be their first public capital event.
How It Compares to Other IPOs
SpaceX has already listed. OpenAI is still private and patient. Anthropic is the AI name closest to a record-breaking debut.
