Shares of [[LINK_START_1]]SoftBank Group[[LINK_END_1]] experienced a notable decline Friday as developments from Oracle sparked fresh uncertainty surrounding artificial intelligence infrastructure financing. The technology investment giant’s stock retreated 3.1% to 6,154.0 yen after Bloomberg disclosed Oracle’s recent actions concerning a substantial data center development.
Oracle delivered a force-majeure notification to Blue Owl’s subsidiary involved in Project Jupiter, an expansive data center facility in New Mexico. The project represents a critical element of Stargate, the half-trillion-dollar AI infrastructure venture uniting Oracle, OpenAI, and SoftBank Group.
Reasons Behind Oracle’s Force Majeure Notice
The database giant issued its notification due to potential complications in obtaining adequate electrical power for the facility. Industry sources informed Reuters and Bloomberg that Oracle seeks contractual protection from financial obligations should construction milestones slip beyond scheduled deadlines.
Initial projections targeted a 2028 operational launch for the data center. However, challenges involving power procurement, construction logistics, and capital availability now cast uncertainty over achieving that target date.
The development has intensified scrutiny regarding whether substantial capital pledges directed toward AI infrastructure can be deployed according to established timelines. Similar operational constraints are affecting numerous technology companies industry-wide.
The circumstances carry particular significance for SoftBank given its expanding leverage to finance artificial intelligence ambitions. The organization completed an $11.1 billion bond offering spanning both dollar and euro denominations this week.
Proceeds from this capital raise are designated partly to support SoftBank’s ownership position in OpenAI. The investment firm has allocated $64.6 billion toward the AI laboratory and anticipates controlling approximately 13% of the company behind ChatGPT in the near term.
Rising Borrowing Expenses for SoftBank
The financing transaction represents the largest high-yield corporate bond offering globally, eclipsing the $10.9 billion issuance from French telecommunications provider Numericable completed in 2014.
SoftBank placed $10 billion in dollar-based securities across three maturity profiles. Coupon rates on these instruments spanned 8.625% to 9.75%.
Additionally, the company issued 1 billion euros in notes carrying yields between 7.125% and 8%. These borrowing costs substantially exceed SoftBank’s 2021 bond transaction, which featured yields ranging from merely 2.125% to 5.25%.
Year-to-date, SoftBank has mobilized $14.6 billion through speculative-grade bond markets. This volume constitutes 63.4% of the complete Asia-Pacific and Japan high-yield corporate bond marketplace, based on Reuters analysis.
Concurrent capital deployment includes SoftBank’s $5.4 billion acquisition of ABB’s robotics division and a $3.1 billion purchase of DigitalBridge.
Fixed-income investors demonstrate heightened selectivity toward AI-connected obligations. Reuters data shows spreads on AI-linked securities expanded to roughly 115 basis points, contrasting with 78 basis points across the broader corporate bond universe.
Debt issuance from hyperscale technology providers is projected to accelerate substantially as organizations seek financing for data infrastructure and semiconductor procurement. This trend intensifies competition within an already crowded lending environment.
SoftBank’s AI infrastructure interests extend through SB Energy, currently positioning for a potential United States equity market debut. The energy subsidiary maintains a $430 billion data center project pipeline, though substantial capacity concentration exists with SoftBank and OpenAI, with extended delivery schedules.
Public listing plans for both OpenAI and SB Energy have encountered postponements, eliminating prospective funding channels for SoftBank during a period of escalating capital costs.
The critical question centers on how SoftBank will secure financing for outstanding AI commitments moving forward. Whether portfolio liquidations or eventual public offerings can generate supplementary capital remains uncertain.
