Overview

• Bloomberg, citing people familiar, reports a recent sale of employee shares that implies a roughly $500 billion private valuation for OpenAI.
• The price marks an increase of about $200 billion from a financing round reported in April.
• At this level, OpenAI is again ranked as the most valuable privately held company, ahead of SpaceX at about $350 billion.
• OpenAI remains private, which limits broad investor access and makes secondary transactions a key source of valuation signals.
• The ChatGPT creator operates in a crowded market that includes Meta, Microsoft, Google, Amazon, and Alibaba, with Microsoft counted among its investors.
