OpenAI is reportedly in discussions for a share sale that could value the company at around $500 billion. This potential valuation marks a significant increase in the company's market worth, reflecting its growing influence and importance in the artificial intelligence sector. The move could attract substantial investment and shape the future landscape of AI development.

OpenAI is increasing its secondary share sale to $10.3 billion, up from an initial target of $6 billion, allowing eligible employees to sell stock at a $500 billion valuation. The opportunity is available to staff who have held shares for over two years, with a deadline at the end of September for participation. The transaction is set to close in October, with notable investors including SoftBank and T. Rowe Price.
