Overview

  • Those talks envisage a roughly $500 billion valuation, a significant jump from the $300 billion set in an April 2025 financing round.
  • If completed, OpenAI’s valuation would exceed SpaceX’s most recent estimates of $350 billion to $400 billion.
  • The proposed sale remains in early-stage discussions, underlining the company’s focus on meeting internal demand for liquidity due to its privately held equity structure.
  • Major backers such as SoftBank and Microsoft have driven past funding rounds yet broader investor participation remains restricted.
  • OpenAI continues to lead AI innovation with ChatGPT and advanced text, image and video generation tools in a highly competitive field.
