OpenAI has closed a new capital raise of $40 billion dollars, at a $300 billion valuation

OpenAI announced on Monday that it plans to raise $40 billion in a new funding round led by SoftBank Group (9984.T), valuing the company at $300 billion. The capital will be used to advance AI research, expand computing infrastructure, and improve its tools and services.

According to a source familiar with the matter, SoftBank is expected to contribute 75% of the funding, with the remaining investment coming from Microsoft (MSFT.O), Coatue Management, Altimeter Capital, and Thrive Capital.

OpenAI said it aims to deliver increasingly powerful tools to support the 500 million people who use ChatGPT each week.

Investor interest in artificial intelligence has surged in recent years, fueled by the rise of AI chatbots and sophisticated AI agents. Enterprises have increasingly adopted AI solutions to boost efficiency and improve customer experiences, while venture capital firms continue to compete for stakes in the most promising AI startups.

Based in San Francisco, OpenAI previously raised $6.6 billion in October, placing its valuation at $157 billion. The new round would nearly double that figure.

"OpenAI has very ambitious plans on many fronts and needs a lot of capital to achieve these goals," said Gil Luria, an analyst at D.A. Davidson & Co.
"The list of investors wanting to support that scope has shrunk and may be largely limited to SoftBank, which itself may not have the necessary capital."

OpenAI is partnering with SoftBank and Oracle (ORCL.N) on the $500 billion Stargate project, which aims to build a network of data centers across the U.S. to support AI workloads.

The Microsoft-backed company also announced plans to restructure by forming a public benefit corporation. This shift is intended to attract greater investment while balancing shareholder interests with broader societal goals.

A source told Reuters on Friday that OpenAI must officially transition to a for-profit entity by year’s end in order to secure the full $40 billion investment led by SoftBank.

With this latest round, OpenAI is poised to join the ranks of the world’s most valuable private companies, alongside SpaceX, China’s ByteDance, and Stripe.
