Alphabet closes $25bn US dollar senior notes offering, taking 2026 debt raised past $45bn
On 10 August 2026 Alphabet closed an underwritten public offering of $25 billion of US dollar-denominated senior notes off its June 2026 Form S-3 shelf (File No. 333-296395), under the February 2016 BNY Mellon indenture. Ten tranches were issued: $750m floating rate due 2028, $1.25bn 4.500% due 2028, $500m floating rate due 2029, $2.0bn 4.625% due 2029, $3.5bn 4.875% due 2031, $2.5bn 5.200% due 2033, $4.5bn 5.450% due 2036, $3.0bn 6.250% due 2046, $4.5bn 6.375% due 2056 and $2.5bn 6.500% due 2066. Coupons of 6.25-6.50% at the long end are notably high for an AA-rated issuer and show the price of raising this much duration at once. Combined with the May euro, Canadian dollar and yen offerings (roughly $21bn) and the June $49.6bn net equity and mandatory convertible raise, Alphabet has taken in well over $95bn of external capital in four months, against a $40bn at-the-market equity programme still undrawn - the clearest single measure of what frontier AI infrastructure now costs.
