The Japanese technology conglomerate [[LINK_START_1]]SoftBank[[LINK_END_1]] is moving ahead with a substantial bond issuance surpassing $11 billion as it gears up for another significant capital deployment related to its OpenAI partnership.

SoftBank Group Corp., SFTBY

The debt offering consists of $10 billion in senior unsecured notes denominated in U.S. dollars, complemented by approximately €1 billion (roughly $1.15 billion) in euro-based bonds.

The capital generated from this transaction will partially support a $10 billion contribution representing the third installment of SoftBank’s continuing investment in the artificial intelligence firm OpenAI.

This substantial transfer is anticipated to finalize on October 1.

Bond Market Strategy Powers AI Ambitions

The U.S. dollar component features three separate maturity profiles: 3.5 years, 5.5 years, and 7.5 years.

Meanwhile, the euro-denominated securities offer investors options between four-year and six-year durations.

Market participants expect pricing to occur on September 24, with settlement following on September 29.

Previously, the investment giant had secured a $10 billion bridge financing arrangement to cover its OpenAI obligations.

According to offering documents, revenues from the new bond sale will retire that temporary credit facility.

Additional funds beyond refinancing requirements may be allocated toward general corporate operations.

Should the transaction close at its targeted size, it would establish a new benchmark as the largest non-financial corporate bond deal ever recorded in the Asia-Pacific and Japan markets, based on LSEG data referenced by Reuters.

The offering would also secure a position among the top 20 largest corporate debt transactions worldwide for the current year.

Credit Assessment Points to BB+ Grade

Fitch Ratings has designated a BB+ rating for the forthcoming debt instruments.

The credit evaluation firm noted that SoftBank’s overall debt burden is projected to expand as the organization funds its investment pipeline.

Nevertheless, Fitch expressed confidence that SoftBank will maintain sufficient liquidity reserves and sustained access to capital market channels.

Citigroup has taken the lead bookrunner role for the dollar-based securities.

JPMorgan holds the equivalent position for the euro segment.

For the dollar notes, Citigroup, Goldman Sachs, JPMorgan, and Morgan Stanley are serving as joint global coordinators.

The euro issuance coordination involves JPMorgan, Deutsche Bank, and Goldman Sachs.

AI Partnership Anchors Corporate Vision

The OpenAI relationship has emerged as a cornerstone of CEO Masayoshi Son’s broader artificial intelligence roadmap for SoftBank.

The conglomerate has pledged tens of billions toward the AI developer as it deepens its involvement in generative AI technologies and supporting infrastructure.

This latest financing underscores the substantial capital requirements necessary to sustain such strategic positioning.

OpenAI continues to allocate significant resources toward computational capacity and infrastructure expansion as it scales its model development and service offerings.

This dynamic has elevated the strategic importance of major external backers like SoftBank.

The debt transaction also follows recent comments from OpenAI CEO Sam Altman indicating the company has no intention of pursuing an initial public offering in 2026.

Consequently, SoftBank’s equity position remains concentrated in a privately-held entity rather than benefiting from a near-term public market exit opportunity.

SoftBank’s Vision Fund has already realized valuation gains across portions of its AI-focused portfolio.

Currently, the firm is leveraging international bond markets to secure financing for its next-phase OpenAI commitment, with the substantial $10 billion disbursement set for October 1.
