SoftBank is scrambling to raise $22.5 billion it needs to invest in OpenAI’s Stargate data center project, it has been reported.

The Japanese conglomerate was a founding partner in Stargate when it was unveiled in January. According to a report from Reuters, it needs to close a $22.5bn funding commitment to the ChatGPT-maker before the end of 2025, and is racing to raise the cash in a variety of ways.

In total, SoftBank has said it will invest $30bn in OpenAI, with a $19bn initial investment specifically for Stargate, the multi-gigawatt plan to build a network of AI data centers around the world.

As reported by DCD, SoftBank has sold its entire stake in GPU giant Nvidia for $5.83bn, and raised $9.2bn by disposing of some of its shares in T-Mobile.

Now Reuters says Masayoshi Son’s company will pursue a variety of other options, including selling some of its shares in Chinese ride-hailing app Didi, while a public listing of payments app PayPay could also raise funds, though this is likely to be in the first quarter of 2026.

Insiders who spoke to Reuters said Son had put a cap of $50 million on investments made by SoftBank’s Vision investment fund, with larger funding projects requiring his personal approval.

SoftBank could also look to borrow against British chip designer Arm. Son’s firm remains the majority shareholder in Arm after its public listing in 2023, and the company’s share price has risen significantly since its IPO. SoftBank has up to $11.5bn borrowing capacity that it could draw on against the company, Reuters said.

Though Son is reportedly fully focused on funneling money to OpenAI, this has apparently not stopped SoftBank investigating deals to acquire DigitalBridge, or its data center company Switch.
