OpenAI Soars to $500 Billion Valuation Milestone

OpenAI has reached a remarkable valuation of $500 billion after a secondary share sale, where current and former employees sold about $6.6 billion worth of their shares to investors including SoftBank, Thrive Capital, Dragoneer Investment Group, Abu Dhabi’s MGX, and T. Rowe Price. This marks a sharp rise from its previous valuation of around $300 billion, showing strong investor confidence in the company’s growth and influence in the AI industry.

The deal builds on earlier financing rounds, with SoftBank already having invested during OpenAI’s $40 billion primary funding round. The company had authorized more than $10 billion worth of stock sales in the secondary market. OpenAI’s strong financial performance also supports this valuation, as it generated $4.3 billion in revenue in just the first half of 2025, already surpassing last year’s total revenue by about 16 percent.

This development comes as competition in the AI sector continues to intensify, with leading technology firms racing to secure top talent and expand their market presence. OpenAI’s higher valuation not only highlights its current strength but also reinforces its position as one of the most influential players shaping the future of artificial intelligence.
