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.
