OpenAI is in advanced talks to sell approximately $6 billion in employee-owned shares, which would value the artificial intelligence company at around $500 billion, making it the most valuable private company globally. This valuation marks a substantial increase from its previous valuations of $157 billion in October 2024 and $300 billion in March 2025. The company, backed by investors including Microsoft and SoftBank, reported its first $1 billion revenue month in July 2025 and has an annual revenue run rate of $12 billion. OpenAI also secured a $40 billion contract with Oracle. Despite its rapid growth, the company faces challenges related to compute capacity, with CFO Sarah Friar highlighting that OpenAI is "constantly under compute" and has a voracious demand for GPUs and computing resources. Friar also indicated that OpenAI may consider going public in the future and envisions selling AI infrastructure services. The ongoing stock sale and valuation discussions underscore OpenAI's expanding influence in the AI industry and its positioning ahead of competitors.
