OpenAI Finalizes $6.6 Billion Secondary Share Sale at $500 Billion Valuation
OpenAI has successfully closed a secondary share sale totaling $6.6 billion, enabling current and former employees to liquidate stock holdings at a record $500 billion valuation. This transaction underscores OpenAI’s dominant position within the artificial intelligence sector and marks a significant milestone for the private technology company. The secondary sale was completed in early September, with eligibility limited to employees who had held shares for more than two years. While OpenAI had authorized the sale of up to $10.3 billion in shares—an increase from the initial target of $6 billion—approximately two-thirds of the authorized shares were ultimately transacted.
Robust Valuation and Strong Investor Appetite
The $500 billion valuation represents a substantial increase from the $300 billion valuation OpenAI held earlier in 2025. Insiders interpret the lower-than-maximum participation in the share sale as a vote of confidence in the company’s long-term growth potential, with investor demand remaining strong despite the elevated valuation. Key investors in this round included Thrive Capital, SoftBank, Dragoneer Investment Group, Abu Dhabi’s MGX, and T. Rowe Price, all of whom had expressed interest in the secondary offering earlier this year.
Industry Leadership Amid Intensifying Talent Competition
This transaction solidifies OpenAI’s status as the world’s most valuable privately held company, overtaking SpaceX’s $456 billion valuation. The company’s valuation surge coincides with an increasingly competitive market for AI talent, with competitors such as Meta reportedly offering nine-figure compensation packages to attract leading researchers. OpenAI’s use of secondary share sales aligns with a growing trend among high-profile startups—like SpaceX, Stripe, and Databricks—to provide liquidity options for employees while remaining private. This strategy serves to retain top talent and reward long-serving employees without resorting to an initial public offering (IPO).
“The lower participation in the share sale is seen internally as a strong endorsement of OpenAI’s future prospects,” said a source familiar with the transaction.
Context of Previous Funding and Outlook
This secondary sale follows a $1.5 billion tender offer completed with SoftBank in November 2024, marking OpenAI’s second major liquidity event in less than a year. As the AI sector continues to expand rapidly, OpenAI’s valuation trajectory and ability to attract investment will be critical metrics to watch. The company’s substantial capital influx supports its ongoing development and infrastructure expansion, including the Stargate AI data center in Abilene, Texas, which CEO Sam Altman recently toured.
