Overview
- SoftBank completed its third $10 billion follow‑on payment to OpenAI, bringing total commitments to about $64.6 billion and leaving it with an estimated 13% stake in the company.
- Most of the cash for the final tranche came from an $11.1 billion high‑yield bond package that priced at yields up to 9.75%, a level that reflects materially higher borrowing costs.
- Market signals show investors were willing to buy the debt but demanded steep compensation, with five‑year credit‑default swap costs on SoftBank rising above 400 basis points.
- Key parts of OpenAI’s headline funding remain conditional because Amazon’s reported $50 billion pledge is tied to milestones and Nvidia did not add an extra $10 billion tranche in October.
- Watch points include how quickly OpenAI brings new compute and data centers online, whether Amazon’s milestone payments materialize, and whether SoftBank can keep its loan‑to‑value ratio below its 25% internal ceiling while managing rising debt service costs.
