Tokyo, August 27, 2026 – SoftBank Group Corp. is considering a colossal bond issuance worth up to US$25 billion, a move that underscores both its ambition to dominate artificial intelligence and the risks of its debt heavy strategy.

The Japanese conglomerate, led by Masayoshi Son, is exploring the sale as part of efforts to finance investments in OpenAI and related ventures, according to people familiar with the matter.

The potential offering would mark one of the largest corporate bond sales in Asia, signaling SoftBank’s determination to secure long-term capital for its AI ambitions.

The proceeds are expected to support financing commitments to OpenAI, infrastructure for data centers, and broader initiatives tied to the global race in artificial intelligence.

For Son, who has long championed AI as the defining technology of the century, the bond sale represents a bold bet.

SoftBank has already poured billions into AI startups and infrastructure, but the scale of this issuance highlights the mounting costs of staying competitive against rivals such as Microsoft, Amazon, and Alphabet.

Market reaction has been cautious. Shares of SoftBank slipped in Tokyo trading following reports of the planned sale, reflecting investor unease over the company’s rising leverage.

Analysts warn that while AI promises transformative returns, the timeline for monetization remains uncertain, raising questions about whether debt financed expansion can deliver sustainable profits.

SoftBank’s reliance on debt markets is not new.

The company has a history of aggressive financing, from its Vision Fund investments to its stake in Arm Holdings.

Yet the sheer size of this proposed bond sale has drawn scrutiny.

Some observers note that banks may hesitate to absorb such risk, leaving SoftBank dependent on retail investors and institutional buyers willing to chase higher yields.

The issuance would also test investor appetite amid a volatile global environment.

Rising interest rates, concerns over tech valuations, and geopolitical tensions have made markets more sensitive to large scale debt offerings.

SoftBank’s ability to secure favorable terms will hinge on convincing investors that its AI strategy can generate returns commensurate with the risks.

Despite skepticism, Son remains steadfast.

He has repeatedly described AI as “the most important revolution in human history,” positioning SoftBank as a central player in shaping its trajectory.

The bond sale, if realized, would provide the financial firepower to back that vision, even as it amplifies the company’s exposure to debt.

The stakes are high. A successful issuance would reinforce SoftBank’s role as a major financier of AI innovation, while failure could deepen doubts about its financial resilience.

For now, the plan reflects both the urgency and fragility of the AI arms race vast sums are being mobilized, but the path to profitability remains clouded.

At its core, SoftBank’s contemplated bond sale is a gamble one that could either cement its place in the AI era or burden it with unsustainable obligations.

Investors will be watching closely as the company moves from deliberation to execution.
