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:
