OpenAI Funding Round Nears $10B at $730B Valuation

Bloomberg reports OpenAI is nearing an additional $10B primary equity deal at a $730B pre-money valuation, with investors including MGX, Coatue Management, Thrive Capital, and possibly Altimeter Capital. The tranche would keep the valuation unchanged from the February round, implying strong demand for OpenAI funding despite the company’s massive capital needs. If closed by end-March, total proceeds across the broader raise could approach $120B (adding the previously secured $110B). That would place OpenAI’s post-money valuation around $840B–$850B, positioning it among the world’s most valuable private firms. OpenAI plans to use the funds for data centers, compute clusters, hiring, and product expansion. The article also cites heavy burn (reported ~$4B per month) but notes revenue support: ChatGPT has surpassed 900M weekly users and more than 50M paid subscribers. Separately, OpenAI’s nonprofit arm plans $1B in 2026 grants focused on AI safety, biological risk mitigation, and life-sciences applications, while leadership changes add emphasis to safety and philanthropy. The foundation’s stake is valued at over $180B, giving it significant influence over how OpenAI funding is deployed. Overall, this OpenAI funding round headline is a major signal of ongoing capital inflows into frontier AI infrastructure.
