The proposed financing would add materially to SoftBank’s debt burden while deepening its exposure to OpenAI’s valuation, funding trajectory and expanding need for AI infrastructure. The transaction also marks SoftBank’s first 144A issuance, broadening its potential access to US high-yield investors.
AFII’s analysis considers the credit, infrastructure and climate dimensions of this strategy. While SoftBank has set targets for net-zero Scope 1 and 2 emissions by FY2030 and net-zero across Scopes 1–3 by FY2050, its associated AI infrastructure plans require substantial, reliable power supply.
In particular, the planned Ohio development is expected to be supported by significant new gas generation capacity. We explore how this concentration of financing, infrastructure and energy risk could affect SoftBank’s deleveraging plans, its reliance on OpenAI, and the credibility of its climate strategy.
