SoftBank
What SoftBank is up to now
New 09-04: the retail bond PRICED at 4.75% — the TOP of the 4.3-4.9% indicative range, not the middle, and more than double the ~2.3% YTD average for comparable yen retail corporate paper. The structure is the read: banks reportedly declined the risk, which removed the underwriter cushion and left households setting the clearing price directly. Seven-year unsecured duration sold to retail, in a rising-JGB regime with the BOJ reportedly weighing a quarter-point hike on 09-18. Japan's retail-bond issuance is at a record Y2.88tn YTD. Compare ByteDance the same morning: $29.6bn UNSECURED and oversubscribed. The market is still discriminating by what backs the borrowing. New 08-29: negotiating to buy majority control of 1X, an OpenAI-backed humanoid-robotics startup, around a $6bn valuation -- reported the same week as the OpenAI-stake loan below. Coverage headlines a "$6bn discount" without establishing the prior valuation it is measured against, so this is logged as the reported deal value only, not a confirmed markdown. New 08-28: borrowing against the OpenAI stake rather than trimming it. A reported $10bn two-year facility secured on the holding, priced around SOFR+275, Mizuho lead arranger, proceeds likely earmarked to refinance the existing $40bn OpenAI bridge loan. The posture is the point: it keeps the position intact while converting paper into spendable cash, stacking a second layer of leverage on an asset that is itself the collateral. HOLD PRECISELY: single-outlet, reported rather than filed. Separately still pending: the Y1tn retail bond prices 09-04.
as of 2026-09-04
Carries the $40B OpenAI bridge loan; the largest single lever into the stack. House Son the obvious next dynast.

This week — what changed
- The same filing's risk factors say the quiet part in SEC prose: SB Energy is "substantially dependent on OpenAI," whose guarantor credit it describes as sub-investment-grade, and 81% of the headline backlog is more than eight years out. OpenAI's PORTS-Pike lease alone is 8.0 of the company's 8.8 GW-IT of signed capacity — about 91% — with the rest split between SoftBank's Cosmos campus and OpenAI's Milam County buildings. OpenAI holds 3,991,809 warrants at a nominal $0.01 strike (ten-year term, reported at roughly $5.5bn in value, up from $3.6bn in January) plus a board designation right above a 5% stake, and separately put $500m of equity into SB Energy and pledged $50m of OpenAI product spend through 2028. Of the $439bn backlog, only about $82bn (19%) is expected to be recognized within eight years — $1bn in 24 months, $12bn in 25-48, $30bn in 49-72, $39bn in 73-96 — with the remaining $357bn "thereafter." SoftBank keeps voting control; SB Energy will list as a Nasdaq "controlled company," with share count and price range still to be filed by amendment. (SEC EDGAR S-1, Yahoo Finance citing WSJ)
- SoftBank's record ¥1 trillion ($6.3bn) seven-year retail bond priced at a 4.75% coupon — the top of the 4.3-4.9% indicative range, not the middle. That is more than double the ~2.3% year-to-date average for comparable yen retail corporate bonds. The structure is the story: banks reportedly declined the risk, which left households to set the clearing price, and they set it high. Japan's retail-bond issuance has hit ¥2.88tn year-to-date, already a record for a full year. (Bloomberg)
