Factbox-From Saudi Aramco to Alibaba: World's biggest IPOs

June 1 (Reuters) - Anthropic ‌said ​on ​Monday it has confidentially filed for a U.S. initial public offering, ‌as the Claude chatbot maker races with ⁠arch rival OpenAI to go public in ‌what would be one ‌of the biggest IPOs of all time.

The move comes ahead of SpaceX's mega ​IPO, which is set to rewrite the record books as the Elon ⁠Musk-led company pursues a $1.75 trillion valuation.

If SpaceX raises the $75 ​billion it wants, the IPO would eclipse the world's largest to date, ​which was oil major ‌Saudi Aramco's listing in 2019.

ChatGPT-maker OpenAI is also preparing to confidentially ⁠file for a U.S. initial public offering in the coming weeks, Reuters had reported ⁠in May, citing a source familiar with the ​matter.

Here is an overview of the biggest IPOs globally, ranked by deal size:
