Japanese investment holding company SoftBank has authorised a further $22.5bn investment in OpenAI, according to a report by the Information.

This latest funding would bring SoftBank’s total commitment to the AI company to $30bn, forming part of a larger $41bn financing round announced in April, reports Reuters.

The Information cited an individual familiar with discussions, stating that SoftBank's board approved the instalment on the condition that OpenAI completes a corporate restructuring aimed at enabling an eventual public listing.

In April 2025, SoftBank initially agreed to provide $10bn, followed by an additional $30bn in December, subject to OpenAI converting to a for-profit structure before the year’s end.

If this restructuring does not occur, SoftBank's investment would reportedly reduce to $20bn.

Neither OpenAI nor SoftBank have commented publicly on the reported agreement, and Reuters has not independently verified the Information’s report.

The funding is structured to support OpenAI’s operational growth and possible transition towards public markets.

The development follows increased investor focus on AI infrastructure and corporate governance models within the sector.

In September 2025, OpenAI, Oracle, and SoftBank unveiled plans to expand the Stargate AI infrastructure project by developing five new data centre sites across the US.

This expansion will boost Stargate’s total capacity to nearly 7 gigawatts (GW) and is backed by investments exceeding $400bn over the next three years. The initiative is part of a strategy to fulfil a 10GW, $500bn commitment by the end of this year.

Recently, SoftBank reached an agreement to acquire the robotics division of Swiss technology firm ABB for an enterprise value of $5.4bn.

The unit, which employs approximately 7,000 people, generated $2.3bn in revenue in 2024, representing nearly 7% of ABB’s total revenue. It also reported an operational EBITA margin of 12.1%.
