OpenAI Secures Additional $10B, Pushing Megaround Past $120B

OpenAI disclosed it is raising an additional $10 billion as part of its historic funding round, with major backers including Andreessen Horowitz, D.E. Shaw Ventures, MGX, TPG, T. Rowe Price, Coatue Management, Thrive Capital, and Altimeter Capital. This fresh capital brings the total haul from OpenAI's latest funding round to over $120 billion, making it one of the largest capital raises in technology history. The company's valuation stands at approximately $850 billion including the newly raised funds, positioning it as one of the most valuable private companies globally.

The additional $10 billion tranche follows OpenAI's announcement last month of a $110 billion commitment from Amazon, Nvidia, and SoftBank. The company's aggressive capital raising reflects its substantial infrastructure and computing power requirements to develop advanced AI systems. OpenAI's CFO indicated this funding round could be the last before a potential IPO later in 2026, signaling the company's trajectory toward public markets. The investments are expected to be finalized by the end of March 2026.
