OpenAI has vaulted past Elon Musk’s SpaceX to become the world’s biggest startup after a share sale to investors including Abu Dhabi firm MGX valued the artificial intelligence giant at $500 billion.
Mubadala and G42-backed MGX, Thrive Capital, SoftBank Group, Dragoneer Investment Group and T. Rowe Price were among the named parties who bought $6.6 billion worth of stock from current and former employees.
The sale fell short of the $10 billion-plus limit on stock the company allowed for sale, potentially indicating the confidence of staff in the long-term trajectory of the business, Bloomberg reports.
It was the third major investment in OpenAI by MGX, which took part in a fundraising round earlier this year that valued the company at $300 billion, after making an initial investment in 2024.
OpenAI and CEO Sam Altman have a tight relationship with the UAE, where the company agreed earlier this year to partner with AI powerhouse G42, Oracle and Nvidia to build a 1-gigawatt computing cluster called Stargate UAE.
Altman met with UAE President Sheikh Mohamed bin Zayed and Sheikh Tahnoon bin Zayed, the National Security Adviser who oversees some $1.5 trillion in UAE assets, in Abu Dhabi on the weekend. He was awarded an honorary doctorate from the Mohamed bin Zayed University of Artificial Intelligence at a ceremony on Friday.
