OpenAI Expands Secondary Share Sale to $10.3B, Hits $500B Valuation

OpenAI has significantly increased its secondary share sale target to $10.3 billion, up from an initial $6 billion, propelling its valuation to $500 billion. The MOVE provides a rare liquidity opportunity for employees holding shares for over two years, with the transaction set to close in October.

High-profile investors, including SoftBank, Thrive Capital, and Abu Dhabi’s MGX, are participating in the deal. Secondary sales like this are becoming a mainstream alternative to IPOs for top-tier private companies seeking liquidity without dilution.

The artificial intelligence leader’s soaring valuation—from $300 billion earlier this year to $500 billion now—underscores its dominant position in the tech landscape. The transaction structure allows existing shareholders to sell stakes to new investors without issuing new shares or raising fresh capital.
