SoftBank is the latest company interested in making a massive investment in OpenAI, with the company reportedly looking to invest as much as $25 billion.

OpenAI has been wooing investors as it continues to spend money at an extraordinary rate in its quest for true artificial intelligence. Microsoft has been one of the company’s largest investors, but the relationship between the two companies appears to be cooling.

According to Financial Times, via TechCrunch, SoftBank could invest between $15 and $25 billion dollars in the AI firm. The investment would be in addition to the $15 billion it plans to invest in the US Stargate AI project.

As the outlets point out, the investment would be SoftBank’s largest since its failed WeWork bet. What’s more, the investment would also serve to give OpenAI more independence from Microsoft.
