Unmasking the AI Bubble: What Bond Investors Must Know to Navigate Uncertainty and Protect Their Future
According to Bob Michele, chief investment officer at JPMorgan Asset Management, the recent surge in bond issuance from hyperscaler tech companies shouldn’t alarm investors. While the market has been preoccupied with geopolitical issues like the U.S.-Iran conflict, stock investors are also wary about the impact of artificial intelligence on certain businesses. However, this disruption doesn’t seem to concern the bond market as much. A recent survey by Bank of America revealed that credit investors now cite an AI bubble as their top worry, with expectations of $285 billion in issuance from major tech firms this year.
Historically, companies like Alphabet, Amazon, Oracle, and Meta have financed their growth through their own substantial cash reserves, but they are now increasingly leaning on the bond market to fund ambitious capital expenditures. “When you see the hyperscalers come to market, it is jarring to a market that has viewed them as having tremendous excess free cash flow,” Michele explained. Yet upon examining credit and leverage metrics, he remains optimistic. In fact, he noted that elevated issuance isn’t unprecedented; similar patterns were seen in the banking sector during the 1990s. Investors tend to adapt over time, distinguishing between solid borrowers and those less likely to perform.
Michele emphasized that these tech giants are approaching the bond market thoughtfully. “They’re not borrowing and spending unless they’re seeing demand there, and that demand must be enormous for them to invest in expansion,” he stated. The presence of strong demand indicates that cash flow should follow. Interestingly, marginal borrowers have yet to tap into the bond market, and much of the financing for AI has shifted to the private credit sector, which is facing scrutiny over its debt issuance.
Market dynamics indicate that an influx of supply may pressure bond valuations, subsequently increasing yields due to their inverse relationship with prices. Guy LeBas, chief fixed income strategist at Janney Montgomery Scott, projects a growth of 9% to 11% in the investment-grade corporate bond market by 2026, following a 6% rise in 2025. Currently, spreads in the corporate bond market are near historic lows, meaning that investors are receiving less compensation for credit risk. LeBas expects spreads to widen as new supply enters the market. “The corporate bond markets have arguably been under-supplied, so pricing is somewhat expensive historically,” he added.
Michele advocates for portfolio diversification that includes hyperscaler bonds, viewing them as reasonably priced. He mentioned his participation in new bond offerings, although he opted not to disclose specific names. “We like the way they’ve managed their business and are confident they can convert capital expenditures into revenue,” he said. The JPMorgan Core Bond Fund holds various Alphabet bonds with maturities ranging from 20 to 40 years.
Conversely, BlackRock’s Rick Rieder remains cautious, suggesting it’s not yet time to invest. He compares current issuers to historical giants like auto manufacturers and utility companies but believes that better opportunities will emerge. “The levels have not been intriguing,” Rieder stated, expressing excitement for future offerings that come with more attractive terms.
Retail investors, too, need to reevaluate their tech allocations, warns LeBas, advising caution in investment-grade bonds. “In equities, there’s a strong case for tech exposure,” he highlighted, “but when it comes to investment-grade bonds, there may be better opportunities for taking on tech risk.” As the bond market evolves, staying informed and prepared could yield strategic advantages for savvy investors.
