The five-year credit default swap spread on SoftBank rose 22 basis points to 466 bps, the widest since October 2022, according to Markit data. The move reflects rising investor scrutiny of the company's finances as it has borrowed more at record yields to fund its $64.6 billion investment in OpenAI.
Why it matters
Concerns about AI profitability have unsettled global financial markets, and the rising credit costs of firms that borrowed to build out AI infrastructure signal growing unease about the sector's debt load. Midterm election results in the United States have also raised questions about the pace of AI infrastructure development.
SoftBank's five-year CDS spread widened to 466 bps, a 22 basis point rise that is its widest level since October 2022. The stake in OpenAI is valued at $64.6 billion, while SoftBank also holds a 90% stake in chip designer Arm.
The players
SoftBank Group
A Japanese multinational conglomerate led by Masayoshi Son that holds major technology investments including Arm and a large stake in OpenAI.
OpenAI
An artificial intelligence research company that develops the ChatGPT chatbot and is backed by a large investment from SoftBank.
Futurum Group
A technology research and advisory firm whose analyst Rolf Bulk authored a report on the risks midterm results pose to US data centre capacity.
The details
SoftBank has taken on more debt at record yields to fund its OpenAI stake, and investors have responded by pricing in greater default risk. OpenAI has delayed its public offering to 2027, adding to uncertainty around the value of SoftBank's holdings.

Data Centers Context
The 466 bps spread matches the stress last seen in October 2022, when SoftBank's credit costs spiked during a broader market sell-off. The renewed widening now centers on borrowing tied to AI infrastructure rather than general market conditions.
Higher credit costs for AI-linked borrowers can ripple into the companies and funds that hold their debt, including pension and retirement portfolios. Delays to AI infrastructure projects could also slow the data centre capacity that many online services depend on.
The takeaway
Rising credit spreads on heavily indebted AI investors are an early signal that the cost of financing the AI build-out is becoming a market concern. Watching how these spreads move will show whether investors see the sector's borrowing as sustainable.
