OpenAI Becomes World's Most Valuable Startup With $6.6B Share Sale

OpenAI has raised a staggering $6.6 billion in a secondary share sale, catapulting the company's valuation to a whopping $500 billion. This makes it the world's most valuable startup, surpassing SpaceX. The sale involved a host of investors, including SoftBank, Thrive Capital, Dragoneer, and MGX from Abu Dhabi.

The sale, worth a hefty $6.6 billion, comes hot on the heels of OpenAI's rival Anthropic raising $13 billion at a $183 billion valuation last month. SoftBank, a major backer, had previously committed $40 billion to OpenAI by the end of 2025, valuing the company at $300 billion.

OpenAI plans to spend big in the coming years, investing hundreds of billions to build computing infrastructure for its AI services. The company generated around $4.3 billion in revenue in the first half of 2025. Meanwhile, Nvidia has pledged an investment worth up to $100 billion, raising concerns about a potential bubble in the generative AI sector.

The successful share sale has solidified OpenAI's position as the world's most valuable startup. With substantial investments planned and a strong revenue stream, the company is well-positioned to continue its growth and innovation in the AI sector.
