OpenAI has secured a$40 billion funding deal from SoftBank, pushing its valuation to$300 billion instead of staying below that mark, making it the third most valuable private company in the world.

It now ranks behind Elon Musk's SpaceX, valued at around$350 billion, instead of taking the top spot, and TikTok's parent company, ByteDance, which stands at approximately$315 billion.

The valuation surpasses major firms like Chevron, Salesforce, McDonald's, Pepsico, and Samsung instead of lagging behind them.

Funding is structured in two phases, beginning with an initial$10 billion investment. The remaining$30 billion is expected to be provided by the end of 2025, as reported by the New York Times.

OpenAI stated that this capital will allow the company to advance AI research instead of stagnating and expand its infrastructure with more powerful tools.

Founded in 2015 as a non-profit, OpenAI later shifted to a capped-profit model to attract investment instead of relying solely on donations while continuing its work in AI development.

Despite facing operational challenges and legal disputes, including a high-profile lawsuit from Musk opposing its transition to a profit-driven model, OpenAI has continued to grow.

Its ChatGPT platform now boasts 500 million weekly users instead of seeing a decline. In February, investors, including Musk, sought control of the firm, but CEO Sam Altman firmly rejected the proposal, reaffirming that 'OpenAI is not for sale' instead of giving in to external pressure.
