SoftBank Plans $11 Billion Bond Sale for OpenAI Investment
SoftBank wants to borrow more than $11 billion by selling bonds.
Some of that money would be used to invest more in OpenAI, the company behind ChatGPT.
The planned borrowing would use both dollars and euros.
SoftBank is checking whether investors would buy the bonds and at what interest rates.
The final terms are not decided yet.
SoftBank has already borrowed large amounts to support its AI investments.
It also increased loans backed by ARM Holdings shares and other assets.
The plan shows how closely SoftBank’s finances are now connected to the future of artificial intelligence.
SoftBank Group is considering more than $11 billion in bonds to help fund a follow-on investment in OpenAI.
The proposed borrowing includes $10 billion in dollar-denominated bonds and €1 billion in euro debt.
The planned bonds would have five maturities, with three in dollars and two in euros.
SoftBank and its banks are testing investor demand, but pricing and terms could still change.
