Lately, the AI phenomenon has emerged as the linchpin narrative in the U.S. stock market's tech landscape, propelling the share prices of the "Magnificent Seven" tech behemoths to repeatedly break new records and igniting a sustained upswing in the three principal U.S. stock indices. As the fervor surrounding AI intensifies, the debate over the existence of an "AI valuation bubble" has reached a fever pitch. Investor sentiment is oscillating wildly between the urge to ride the wave and the caution to steer clear of potential pitfalls, resulting in notable volatility in the U.S. stock market.

Presently, these concerns about an "AI bubble" have spilled over into the bond market. The U.S. AI sector has recently witnessed a "bond issuance craze," with industry giants like Google, Meta, and Oracle undertaking substantial financing endeavors in the bond arena. Despite the fact that these new bond offerings have been met with overwhelming demand, apprehensions regarding an "AI bubble" within the bond market are steadily gaining traction.
