SoftBank Retires $25.9 Billion Bridge Loan as Bond Investors Line Up

SoftBank will repay its $25.9 billion bridge facility on September 15, ahead of schedule, as it prices a ¥1 trillion bond and weighs a dollar high-yield sale.

SoftBank Group is wasting little time in reshaping the debt stack behind its artificial-intelligence ambitions. The Japanese conglomerate said it will repay the entire outstanding balance of its $25.9 billion bridge facility on September 15, well ahead of schedule, drawing on the financing arrangements tied to its OpenAI commitment. Of the $40 billion facility originally arranged, $30 billion had been tapped.

The early repayment lands in the middle of a crowded funding calendar. On September 4, SoftBank priced its 70th unsecured corporate bond — a ¥1 trillion issue with a seven-year tenor and a 4.75% coupon. The deal settles on September 17, with proceeds earmarked to redeem domestic notes and to help bankroll the purchase of ABB Ltd.'s robotics division. Retail subscriptions opened on September 7 and run through September 16.

Demand from Japanese households has been brisk. Several domestic brokerages reported their allocations for individual investors sold out shortly after the sales window opened, a sign that home-market confidence in the group has held up even as its leverage climbs. The picture is rounded out by investor meetings in New York running from September 14 to 17, where Chief Financial Officer Yoshimitsu Goto is sounding out appetite for a potential dollar-denominated high-yield bond. Media reports suggest the group could raise between $10 billion and $20 billion, possibly with a euro tranche attached.

A Balance Sheet Built for Scale

The two moves — retiring the bridge loan early while lining up fresh paper — point to a company deliberately diversifying how it funds its multi-billion-dollar bets on AI and robotics rather than leaning on a single credit line. That strategy carries a cost. SoftBank sits at BB+ with S&P Global Ratings, the top rung of speculative grade, a notch below the investment-grade status enjoyed by the tech giants it competes with. Japanese media have drawn the contrast sharply: Alphabet carries AA+, Amazon AA.

The gap matters because the borrowing is set to grow. Bloomberg Intelligence analyst Sharon Chen estimates gross debt could climb from roughly $80 billion in March 2025 to more than $130 billion if SoftBank finances its pipeline through debt.

Skeptics Supply the Fuel

Meanwhile, the equity has been on a tear. Friday's session added 2.1%, taking the shares to €37.45, after closing at €36.70 on Thursday. The seven-day gain stands at 23%, the 30-day advance at 22%. Market capitalization has reached about €209.09 billion.

What makes the run notable is who is on the other side of it. Short interest as a share of free float rose to 2.27% by Wednesday, the highest since July 2025, according to Bloomberg. The notional value of those bearish positions hit $3.9 billion — a record at least since early 2015. Bloomberg speculates that a forced unwind of those bets could push the stock even higher, meaning the more convinced the skeptics became, the more fuel they supplied for the move they were betting against.

That rally does not come without warning signs. The relative strength index reads 71.2, firmly in overbought territory, and annualized volatility of 62% suggests the market is prone to sharp reversals. For investors, the question has shifted from price momentum to how SoftBank manages its expanding debt load. Retiring the bridge loan curbs near-term refinancing risk, while the yen bond and the prospective dollar sale show a group intent on spreading its funding sources. Whether the New York meetings generate the same reception the domestic bond enjoyed should become clear in the coming days.
