SoftBank Funding Could Lead OpenAI to IPO

SoftBank Group confirmed a $40 billion unsecured bridge loan on March 27, 2026, to finance its $30 billion commitment to OpenAI. The loan’s short-term structure has fueled speculation that OpenAI’s long-anticipated initial public offering could arrive before the end of the year.

SoftBank Group confirmed Friday it has secured a $40 billion unsecured bridge loan to fund its $30 billion commitment to OpenAI, the maker of ChatGPT. The loan’s structure short-term, backed by Wall Street heavyweights, and carrying no collateral has drawn fresh scrutiny about when OpenAI may finally go public.

The loan, which matures in March 2027, was arranged with a consortium of five major banks: JPMorgan Chase, Goldman Sachs, Mizuho Bank, Sumitomo Mitsui Banking Corp. and MUFG Bank, the company said in a statement.

Most striking is that the loan is unsecured and has a 12-month term, meaning it must be repaid or refinanced by next year. This could be a signal that lenders believe OpenAI’s highly anticipated public listing will indeed come later this year.

The reasoning is straightforward, if OpenAI’s IPO proceeds as expected, SoftBank would gain the liquidity needed to repay the debt within the loan’s window. In other words, Wall Street’s willingness to extend an unsecured $40 billion facility to SoftBank may itself be the strongest signal yet that major financial institutions expect a listing to materialize.

SoftBank’s latest $30 billion commitment is part of OpenAI’s record-breaking $110 billion funding round, announced Feb 27, 2026, consisting of a $50 billion investment from Amazon as well as $30 billion each from Nvidia and SoftBank, against a $730 billion pre-money valuation. The post-money valuation reached $840 billion, making OpenAI the most valuable private technology company in history.

A month after the initial announcement, OpenAI CFO Sarah Friar disclosed that the round has since grown to north of $120 billion, with Andreessen Horowitz, D.E. Shaw Ventures, MGX, TPG, T. Rowe Price and Microsoft among the new participants.

By the end of 2025, SoftBank held an estimated 11% stake in OpenAI through earlier investments and deals. With the new $30 billion commitment through Vision Fund 2, SoftBank’s total investment in the ChatGPT maker now exceeds $60 billion.

A key driver behind SoftBank’s financial recovery has been its AI investments, especially OpenAI, from which the Japanese technology and investment giant has already recorded approximately $19.8 billion in cumulative valuation gains over the nine months through December.

SoftBank has unloaded assets, including its stake in NVIDIA, to bankroll its growing bet on OpenAI. The U.S. company now represents one of SoftBank’s biggest holdings, alongside a roughly 90% stake in chip designer Arm Holdings.

SoftBank and OpenAI were among the companies behind the Stargate Project, which said it aimed to invest up to $500 billion over four years to build AI infrastructure in the United States. SoftBank founder Masayoshi Son separately pledged to invest $100 billion in AI and related infrastructure in the U.S. over four years, an announcement made alongside then President-elect Donald Trump in December 2024.
