AI Boom Drives Record $3.68T Global Corporate Bond Issuance
According to a London Stock Exchange Group (LSEG) report, global corporate bond issuance reached a record $3.68 trillion in the first half of 2026, representing a 10% year-over-year increase. This surge was heavily driven by massive fundraises from tech giants to fund AI and cloud computing infrastructure. This trend highlights the immense capital requirements of the AI race, as tech companies increasingly rely on debt markets to finance expensive data centers and hardware. It signals that the AI infrastructure buildout is accelerating, shifting macroeconomic capital flows toward technology sectors. While the total issuance value rose, the number of deals fell by 12% to 10,408, indicating larger individual transaction sizes. Amazon led the wave with a combined $54 billion raised in March 2026 through USD and EUR-denominated bonds for cloud and AI data centers.
