SoftBank's record $11 billion junk-bond sale comes as corporate borrowing has surged this year, with Amazon, Alphabet and Tencent among the major issuers. The offering's highest-ever yields suggest investors are demanding greater compensation for the risk tied to SoftBank's strategy. That strategy leans heavily on AI, including $64.6 billion in backing for OpenAI, which has made the conglomerate a bellwether for AI sentiment. The pressure on CEO Masayoshi Son is compounded by his mixed track record: his Alibaba investment succeeded, but he directed $16 billion to Adam Neumann's WeWork, which ultimately went bankrupt. The bond sale's terms appear to reflect concerns about possible overheating in the AI market, though the body does not specify what those concerns are beyond that phrase.
