SoftBank Provides $40 Billion Bridge Loan to OpenAI

SoftBank Group secures a $40 billion unsecured bridge loan from Goldman Sachs, JPMorgan Chase, and three Japanese banks to increase its stake in OpenAI from 10% to 13%, bringing its total investment to $64.6 billion. The bridge loan, executed on March 27, 2026, matures in one year and will support SoftBank's general operations while fulfilling its follow-on commitment to OpenAI. This follows OpenAI's massive $110 billion funding round in February 2026 that included $50 billion from Amazon and $30 billion from Nvidia, with Microsoft maintaining the largest stake at 27%. SoftBank CEO Masayoshi Son is also backing the $500 billion Stargate AI infrastructure project alongside OpenAI, positioning the Japanese conglomerate as a major player in the global AI race despite taking on significant financial leverage.
