Per Bloomberg, Microsoft is returning to the US bond market for the first time since its $17B sale in 2017, seeking at least $25B across up to 10 tranches. Its 40-year note is priced near Alphabet's and Amazon's long bonds despite Microsoft's stronger AAA rating, suggesting the flood of AI data center debt is lifting borrowing costs for everyone.
