Corporate bond issuance worldwide reached approximately $3.68 trillion in the January-June 2026 period, marking a new first-half record as companies compete to finance artificial intelligence (AI) investments. This surge is driven largely by hyperscale technology firms such as Amazon and Oracle, which are issuing tens of billions of dollars in bonds to fund AI-related initiatives including data centers.

However, the aggressive borrowing has raised concerns among investors, who are beginning to seek higher yields amid widening credit spreads. The trend highlights the growing financial momentum behind AI development but also signals caution in the bond market regarding the sustainability of such rapid debt accumulation.

This information was reported from Tokyo and reflects a global trend in corporate finance linked to the AI funding race.
