727 FinancePANews reported on October 4 that American billionaire and well-known investor Grant Cardone pointed out that driven by competition in the field of artificial intelligence, technology giants such as Meta, Google, and Amazon are raising funds through the issuance of high-yield (junk) bonds to maintain investment in research and development. About US$66 billion of such bonds have been sold worldwide, with coupon rates as high as 9.75%. Cardone analyzed that these technology companies believe that they must invest in AI at all costs to survive, but once the subsequent implementation results do not meet expectations, the related bond interest rates will fall back.
