OpenAI is the world's largest company with a $500 billion investment and UAE participate.

OpenAI has surpassed Elon Musk's SpaceX to become the world's most valuable private company, after completing a deal allowing its employees to sell their shares at an estimated valuation of $500 billion.

According to Bloomberg News, current and former OpenAI employees sold $6.6 billion worth of shares to investors including Thrive Capital, SoftBank, Dragoneer Investment Group, the UAE's MGX, and T. Rowe Price. This deal significantly increased the US company's valuation from the $300 billion it reached in a previous funding round led by SoftBank earlier this year.

In the same context, a source confirmed to Reuters on Thursday that OpenAI's value reached $500 billion after a deal in which current and former employees sold approximately $6.6 billion worth of shares. This rapid rise reflects the investment frenzy surrounding AI technology pioneers, which are expected to radically transform the global economy and industry.

OpenAI, led by Sam Altman, is among the most prominent companies leading this race, alongside companies like Nvidia, as organizations race to build data centers and develop AI services—projects that could require trillions of dollars.

Although the company has yet to turn a profit, it is contributing to this expansion by concluding massive deals with companies like Oracle and SK Hynix. The new deal has boosted OpenAI's valuation above SpaceX's approximately $400 billion, at a crucial time for the company, which is in negotiations with Microsoft to transition to a traditional for-profit entity.

OpenAI was founded in 2015 as a nonprofit organization aiming to develop artificial intelligence for the benefit of humanity. However, the planned changes will give the existing nonprofit entity control over a new public-benefit company.

OpenAI generated revenues of approximately $4.3 billion in the first half of 2025, an increase of approximately 16 percent over the entire previous year, according to Information this week.

The following is a ranking of the world's most valuable private companies, according to Bloomberg:

OpenAI (USA) $500 billion

SpaceX (USA) $400 billion

ByteDance (Chinese) $220 billion

Anthropic (USA) $183 billion

Ant Group (China) $150 billion

Reliance Retail (India) $100 billion
