Alphabet Floats £1 Billion Century Bond Amid $32 Billion, Three-Currency AI Funding Blitz

Private companies issuing 100-year debt is historically rare: Motorola’s 1997 dollar century bond ($0.3 bn) and IBM’s 1996 issue are the tech sector’s only precedents, while Argentina’s 2117 sovereign bond famously defaulted within three years. Alphabet’s move echoes the late-19th-century railroad era when dominant firms financed vast physical networks with ultra-long bonds, and more recently Austria’s 2120 note (0.85%, 2020) that has since lost >70% of its value as rates normalised. The offering underscores two secular shifts: (1) Big Tech’s transition from “asset-light” software margins to capital-hungry, quasi-utility AI infrastructure, and (2) the bond market’s willingness—driven by pension and re-insurance liability matching—to treat a $4 trillion platform company as infrastructure on par with sovereigns. On a 100-year horizon this moment may prove either a watershed, cementing megaplatforms as enduring public-utility-like entities, or a sign of exuberance near the apex of an AI investment cycle whose pay-offs remain uncertain across technological epochs measured in mere decades.
