June 11 (Reuters) – Elon Musk’s SpaceX raised $75 billion in its blockbuster initial public offering on Thursday, shattering records and eclipsing Saudi Aramco’s 2019 listing by a wide margin to become the largest ​IPO ever.

The rocket and satellite maker is set to debut on ‌the Nasdaq on Friday, a listing expected to usher in a wave of mega IPOs.

High-profile private startups, including ChatGPT-maker OpenAI and rival Anthropic, have in recent weeks taken key steps toward stock market listings.

AI GIANTS MOVE CLOSER TO MEGA IPOs

Here is an overview of some of the other mega IPOs expected in 2026:

OPENAI

OpenAI, which operates AI chatbot ChatGPT, revealed on Monday it had ​confidentially filed for a U.S. initial public offering as investors seek exposure to the AI boom.

“We have not decided on timing yet; it ⁠may be a while because there are things ⁠we want to do that are likely easier as ​a private company,” OpenAI said.

“But it’s a complicated set of tradeoffs and this ​gives us the option to go public sooner if that ends ‌up being best.”

OpenAI is aiming to go public as early as September, Reuters reported last month. It was laying the groundwork to go public in an offering that could value it at up to $1 trillion.

In May, the Sam ⁠Altman-led company fended off an existential court challenge from Elon Musk, simplifies the path for OpenAI to proceed with a stock market listing.

ANTHROPIC

AI heavyweight Anthropic revealed ⁠earlier this month it ‌had confidentially filed for a U.S. initial public offering, ⁠setting the stage for what could become a watershed ​moment for ‌Wall Street’s AI frenzy.

Anthropic, which operates AI chatbot ​Claude, last raised $65 ⁠billion at a post-money valuation of $965 billion in late May, putting it ahead of rival OpenAI.

The listing would represent one of the most consequential stock market debuts in years, potentially reshaping benchmark indexes, investor flows and the broader narrative driving U.S. equities.
