- The Japanese conglomerate is also preparing an offshore bond sale of up to $20 billion alongside a record 1 trillion yen retail bond.
Japanese technology investment giant SoftBank Group is assembling another massive borrowing package to fund its high-stakes artificial intelligence expansion. According to people familiar with the transaction, the Tokyo-based conglomerate is seeking a fresh $10 billion bank loan to help refinance debt obligations tied to its multi-billion-dollar stake in ChatGPT developer OpenAI. The financing adds to an aggressive wave of borrowing by founder Masayoshi Son as the firm races to secure a commanding position in the global artificial intelligence sector.
The proposed borrowing is structured as a two-year loan facility with an interest margin of approximately 275 basis points over the benchmark Secured Overnight Financing Rate. Japanese financial giant Mizuho Bank is serving as the mandated lead arranger and bookrunner for the debt syndicate. Lenders are currently evaluating the credit package, with bank commitments due by the end of August as institutional syndication gathers momentum across international financial centers.
The primary objective of the new loan facility is to help refinance a massive $40 billion bridge loan that SoftBank secured earlier in the year to finance its multi-stage equity injections into OpenAI. Under an ambitious investment roadmap, the Japanese conglomerate is slated to invest nearly $65 billion in the artificial intelligence pioneer by October. Completing these capital contributions will grant SoftBank an estimated 13% ownership stake in OpenAI, cementing the enterprise as one of the startup’s largest and most influential institutional backers.
The $10 billion loan represents just one component of a multi-pronged debt refinancing strategy. SoftBank is concurrently working with international investment banks to prepare an offshore corporate bond offering of between $10 billion and $20 billion, scheduled to launch as early as September. The potential bond issuance—which may be denominated in both United States dollars and euros—could rank as the largest corporate bond issue by an Asian company this year, allowing the firm to extend its debt maturities across institutional bond markets.
In addition to tapping global credit markets, the conglomerate is mobilizing capital in its home market through a historic retail debt offering. SoftBank is preparing to issue a record 1 trillion yen, equivalent to roughly $6.3 billion, in seven-year corporate bonds marketed directly to Japanese household savers. Dangling an expected annual coupon in the upper 4% range, the retail bond sale enables the firm to tap into Japan’s massive household cash savings while reducing its reliance on traditional commercial bank syndicates.
The aggressive borrowing spree is attracting heightened scrutiny from fixed-income analysts and rating agencies. While market enthusiasm for generative artificial intelligence remains high, corporate debt issuance across the global technology infrastructure ecosystem has topped $410 billion this year. Carrying speculative-grade corporate credit ratings, SoftBank’s decision to layer tens of billions of dollars in loans and bond obligations onto its balance sheet increases its annual interest payment burden, leaving the conglomerate vulnerable if artificial intelligence monetization timelines stretch longer than anticipated.
To reassure institutional lenders and rating agencies, corporate leadership is leveraging its valuable equity portfolio as collateral. The firm previously secured a $10 billion margin loan backed directly by its equity holdings in OpenAI and British chip designer Arm Holdings. The soaring market valuation of Arm—which expanded significantly during the artificial intelligence hardware boom—provides SoftBank with a vital liquid equity cushion, giving the parent company a total market capitalization of roughly $182.8 billion to support its debt service capabilities.
The relentless capital mobilization supports Masayoshi Son’s overarching vision of building a global physical artificial intelligence empire. Beyond its direct stake in OpenAI, SoftBank is deploying capital across advanced robotics and computing infrastructure. The company agreed to acquire the industrial robotics division of Swiss engineering leader ABB for $5.4 billion, invested $200 million into autonomous construction startup Gravis Robotics, and is currently in advanced discussions to acquire a majority stake in humanoid robotics startup 1X Technologies at a $6 billion valuation.
As banks finalize their commitments for the $10 billion loan facility, SoftBank’s aggressive financial maneuvers underscore the immense capital requirements of the artificial intelligence era. By combining syndicated bank debt, global corporate bonds, and domestic retail savings into a multi-billion-dollar war chest, Masayoshi Son is executing a high-stakes financial gamble. The outcome will determine whether SoftBank’s massive bet on OpenAI and physical robotics transforms the company into the undisputed titan of the modern technological revolution.
