A consortium of 21 additional financial institutions has joined SoftBank’s unprecedented $40 billion bridge financing arrangement intended to support its substantial investment in OpenAI, according to sources with direct knowledge of the transaction.
These newly participating banks have collectively secured approximately $7 billion from the overall credit facility. Among the largest participants, First Abu Dhabi Bank, Singapore’s sovereign wealth fund GIC, and Standard Chartered Bank have each committed portions approaching $1 billion. Additional participants include banking institutions from Europe, Japan, and Taiwan.
The initial underwriting banks and senior lenders continue to hold the remaining $33 billion portion of the financing package. Industry sources indicate this segment may undergo further distribution among additional banking institutions, following conventional practices for transactions of this magnitude.
The financing agreement was executed in March with a maturity date of March 2027, establishing a 12-month term. Financial analysts classify this as among the most substantial bridge financing transactions ever arranged within the Asia-Pacific markets, with underwriting fees projected to exceed $100 million.
The lead arranging institutions for this transaction include JPMorgan Chase, Goldman Sachs, Mizuho Bank, Sumitomo Mitsui Banking Corporation, and MUFG Bank. Additional sub-underwriting support comes from HSBC, BNP Paribas, and Intesa Sanpaolo.
Capital Distribution to OpenAI
The credit facility was engineered to finance a $30 billion follow-on capital injection into OpenAI via SoftBank’s Vision Fund 2 investment vehicle. An additional $10 billion allocation supports broader corporate operations.
The initial drawdown of $10 billion occurred on April 1, 2026. Two subsequent disbursements of $10 billion are planned for July 1 and October 1 of the current year.
The financing arrangement features an initial interest margin of approximately 250 basis points above the Secured Overnight Financing Rate. Based on prevailing rates, this translates to an effective interest rate near 6.14%.
Son’s Massive AI Investment Strategy
SoftBank chairman and CEO Masayoshi Son has maintained a prominent and public commitment to OpenAI for an extended period. His aggregate financial commitments to the artificial intelligence company have now climbed beyond $60 billion.
OpenAI submitted documents for a public offering last month, following a March funding round that established the company’s valuation at $852 billion.
The $30 billion channeled through this financing structure constitutes one of the most substantial individual capital deployments ever directed toward a privately held technology enterprise. For perspective, Vision Fund 2’s original capitalization totaled approximately $56 billion.
The 12-month loan framework necessitates that SoftBank either refinance the debt, liquidate assets, or secure equity capital prior to the March 2027 deadline.
Several banking executives previously expressed reservations regarding SoftBank’s concentrated exposure to OpenAI, particularly as the company confronts intensifying competition from challengers such as Anthropic.
Prior to the broader syndication phase initiated in May, nine banking institutions had already participated in the financing arrangement.
Representatives from SoftBank, First Abu Dhabi Bank, Standard Chartered, and GIC all declined to provide statements.
