OpenAI secured $110 billion in new funding on Friday at a $730 billion pre-money valuation to support infrastructure expansion. 

Amazon (NASDAQ: AMZN) provided $50 billion of the total investment. SoftBank Group and NVIDIA (NASDAQ: NVDA) each contributed $30 billion to the round, and additional investors are expected to join the raise as the process advances.

The capital raise coincides with a 300% increase in weekly users for the Codex product since the start of the year, OpenAI said.

OpenAI signed a multi-year strategic partnership with Amazon to accelerate global AI innovation. The organization also expanded a computing agreement with NVIDIA to secure 3GW of dedicated inference capacity and 2GW of training capacity. This NVIDIA expansion builds upon existing Hopper and Blackwell deployments using new Vera Rubin systems.

OpenAI’s new $730 billion valuation pushes the OpenAI Foundation stake in OpenAI Group past $180 billion. This funding round addresses capital requirements as the organization builds out infrastructure. Previous estimates projected OpenAI to spend $115 billion through 2029 on operating activities and data centers.

ChatGPT currently maintains more than 900 million weekly active users alongside 50 million consumer subscribers and over 9 million business subscribers who utilize the system for enterprise applications.

Amazon recently acquired power agreements to support AI/HPC infrastructure partnerships. The technology provider signed a $5.5 billion lease for 300MW of power at the Bear Lake facility operated by Cipher Mining (NASDAQ: CIFR). This 15-year agreement provides the physical electricity required for large-scale computing deployments.
