The SoftBank OpenAI investment plan has entered a new funding phase. According to a term sheet reported by Reuters, SoftBank Group Corp has launched senior unsecured notes worth $10B and €1B, a package that adds up to roughly $11 billion in dollar terms.
The term sheet surfaced on Monday, and the group could not be reached immediately for comment because it was a holiday in Japan.
For readers following crypto news today, the sale is a useful reminder of how much capital artificial intelligence expansion now requires.

The offering is split across five maturities, which spreads repayment dates instead of stacking them in a single year.
Series | Currency | Tenor |
Dollar (short) | USD | 3.5 years |
Dollar (mid) | USD | 5.5 years |
Dollar (long) | USD | 7.5 years |
Euro (short) | EUR | 4 years |
Euro (long) | EUR | 6 years |
Senior unsecured notes carry no specific collateral and rank ahead of subordinated debt.
That structure is common for large corporate borrowers, and the mix of dollar and euro buyers widens the potential investor base.

Proceeds are tied to the group's next payment on its follow-on stake in the ChatGPT maker. Because the SoftBank OpenAI investment arrives in stages, each stage needs its own cash source.
A $10B payment for the third tranche of the follow-on stake.
General corporate purposes, a standard clause that gives the issuer room to handle other needs.
Stating the use of funds gives buyers a simple story to evaluate.
The group earlier secured a $10B bridge loan facility for the same purpose, and the term sheet says the new notes will cancel it. Bridge loans are short-term stopgaps.
Feature | Bridge Loan | New Debt |
Typical role | Short-term cover | Longer-term funding |
Repayment timing | Sooner | 3.5 to 7.5 years in dollars |
Status | To be cancelled | Launched |
Longer maturities usually lower refinancing pressure, though they lock in the coupon investors demand at pricing.
That shift matters because the SoftBank OpenAI investment will no longer depend on a short-term facility.

The term sheet lays out a tight sequence, so timing matters as much as size.
Date | Event |
September 21 | Notes launched, sale opens |
September 24 | Pricing expected |
September 29 | Settlement expected |
October 1 | Follow-on closing expected |
Settlement on September 29 leaves two days before the follow-on closing, a tight gap for the SoftBank OpenAI investment timetable. Three practical points follow from that calendar:
The pricing date sets the final terms for every maturity.
Settlement is when buyers pay and the group receives the funds.
Any slip in either step would ripple into the closing.
Large financings like this show how AI expansion now leans on debt markets as well as equity. Buyers of the notes will weigh the SoftBank OpenAI investment case against several factors:
The coupon on offer compared with similar corporate debt.
How much weight the AI lab now carries in the group's spending plans.
Broader credit market conditions during the sale week.
Traders in the crypto market also watch financings of this size, because AI projects and digital assets compete for the same pool of risk capital.
The sale gives the group a longer runway and matches cash to its next scheduled payment, which is a sensible move for a borrower with large commitments ahead.
It also underlines how deeply the AI lab has become part of the group's financial planning.
The SoftBank OpenAI investment will stay in focus until pricing and the follow-on closing are confirmed.
Anyone tracking crypto news today should watch that outcome, since strong or weak demand will hint at how eager capital markets are to fund AI growth.
