SoftBank is on the verge of finalizing a *$40 billion investment in OpenAI,* pushing its valuation to $300 billion, according to sources. This deal will make SoftBank the largest backer of OpenAI, overtaking Microsoft, which had previously led investments in the AI powerhouse. The funding will be distributed over the next 12 to 24 months, with the first tranche expected as early as spring. A significant portion of the investment is earmarked for Stargate, an ambitious AI infrastructure project backed by OpenAI, Oracle, and SoftBank, announced by Donald Trump earlier this year. The initiative aims to strengthen U.S. AI capabilities, injecting billions into AI research and deployment. OpenAI, under the leadership of Sam Altman, remains at the forefront of the generative AI revolution, competing with industry giants such as Elon Musk’s xAI, Google, Amazon, Meta, and Anthropic. The company continues to expand its reach with strategic partnerships, this high-stakes investment signals a new era of AI dominance.
