SoftBank borrows $11.1 billion in dollars and euros from lenders outside Japan

The euro leg is small. EUR 1 billion at the release's rate of $1.1383 per euro is about $1.14 billion, roughly 10% of an $11.14 billion total, so the three dollar tranches carry nearly nine-tenths of the principal ^[2][3][1][2]. The euro notes stop at 2032. Only the dollar side runs to 2034, the longest date in the deal ^[1].

SoftBank also states the total in yen, at JPY 1,763.2 billion ^[2]. That is the $10 billion at 158.30 yen, or JPY 1,583 billion, plus the EUR 1 billion at 180.19 yen, or JPY 180.2 billion ^[4][5][3]. The three rates in the release agree with each other: 180.19 divided by 158.30 is 1.1383 ^[4]. The split sets the currency exposure. Before any hedge, each 10 yen added to the dollar's price raises the yen cost of repaying the $10 billion by JPY 100 billion, about 6% of that leg ^[5].

The buyer pool is narrow by the release's own terms. In the United States the notes go only to investors reasonably believed to be both qualified institutional buyers under Rule 144A and qualified purchasers as defined in Section 2(a)(51) of the Investment Company Act ^[6]. Everyone else buys offshore under Regulation S, and there is no public offering in any jurisdiction ^[6][9]. The release sets that second test beside SoftBank's statement that it has not registered, and does not intend to register, as an investment company ^[7]. It is not registering the notes under the US Securities Act either ^[7]. Residents of Japan, including Japanese corporations, cannot be offered the notes except where Japanese law permits ^[8].

Because the release text does not state coupons, issue prices, ratings or the use of proceeds, it cannot show that high-yield buyers are paying for AI spending, or what they charged against government bond yields. Three readings fit the same $11.1 billion ^[2]. Coupons near SoftBank's prior borrowing costs would mean the size measures appetite. Coupons well above them would mean the size was bought with yield. A use of proceeds that mostly refinances maturing debt would tell investors little about new investment of any kind.

In my view the release supports a narrower claim: SoftBank can place five tranches in two currencies with a buyer pool limited by two US tests and closed to Japanese residents ^[1][6][8]. The counter-thesis is that qualified institutions will take almost any size if the coupon is high enough, so size alone proves access, and only the coupon shows its cost. Pricing that matches the second reading would prove the appetite thesis wrong.
