AI investment fever spills over into the credit financing market, with large technology companies issuing bonds worth over a trillion US dollars this year.

Technology companies that need a large amount of funding to foot the bill for their ambitions in artificial intelligence are achieving heavyweight debt financing deals at the fastest pace in recent years, capitalizing on investors' insatiable interest to secure funding, even though there is no guarantee that the related investment projects will ultimately yield returns. Borrowers are tapping into various credit financing channels to find the right buyers. According to Bloomberg data, technology companies have raised approximately $157 billion in the US public bond market so far this year, an increase of about 70% from the same period last year. Oracle led the way by issuing nearly $26 billion in public trading bonds, with most of the proceeds coming from a large bond issuance on Wednesday. The company is prepared to spend billions of dollars to lease data centers equipped with Nvidia chips and provide them to customers of artificial intelligence such as OpenAI. "This is the latest indication that the AI investment frenzy, which has long been a focus in the stock market, is spilling over into the credit market," wrote Jonathan Owen, a member of TwentyFour Asset Management's investment-grade investment portfolio management team, in a letter to investors on Thursday.
