OpenAI Valuation Jumps 20% to $933 Billion as GPT-5.6 and Codex Revive Demand
2 articles · Updated · Business Insider · Jul 20
Summary
$933 billion is OpenAI's latest secondary-market valuation, up 20% in three months as investor demand rebounded after a weak early second quarter.
GPT-5.6 Sol, Terra and Luna, released this month after a June preview, helped draw buyers back, while Codex and ChatGPT Work reached 9 million active users across two enterprise platforms.
Anthropic still leads private-market appetite, with about five buyers for every two seeking OpenAI shares, but traders said OpenAI is getting bid far more often than a month ago.
OpenAI's relative discount has also become part of the appeal after Anthropic climbed to a $1.2 trillion valuation, prompting some investors to hedge Anthropic positions with cheaper OpenAI stock.
The rebound follows months of concerns over slower growth, executive turmoil and competition, and it still faces pressure from Anthropic, Chinese rivals such as Moonshot AI and open-source models.
