SoftBank has been aggressively investing in artificial intelligence (AI), funding its initiatives through borrowings, bond sales, and asset disposals. This includes the sale of stakes in companies like NVIDIA and T-Mobile.

The company's latest bond issuance comes as firms across Asia are increasing their spending on AI infrastructure.

Just recently, Chinese e-commerce and cloud computing company Alibaba announced a $10.2 billion share placement to bolster its "full stack" AI capabilities.
