Global credit markets are flashing their strongest risk-off signal in more than a year. The prospect of technology companies borrowing heavily to build out artificial intelligence infrastructure, combined with rising oil prices and political turmoil in France, has driven corporate bond spreads sharply wider across the globe.

Bloomberg index data shows that global investment-grade corporate bond spreads surged to 129 basis points on Thursday, the widest level since May 2025.

Meanwhile, the CDX investment-grade index, which tracks the cost of default protection on U.S. blue-chip corporate debt, rose to 64 basis points on Friday, touching its highest point since March. Asia's high-rated dollar bond spreads also widened to their highest since July 2025, with heightened volatility forcing the Export-Import Bank of Korea to postpone a yen bond issuance.

At the heart of market concerns is the fact that tech giants led by Meta are preparing fundraising on an unprecedented scale, while whether AI investments can be converted into profits in a timely manner remains uncertain.

David Del Vecchio, co-head of U.S. investment-grade corporate bonds at PGIM Credit, said, "The market is digesting the shock from the potential issuance volume needed for AI buildout, and investors have little incentive to step in proactively to fill the gap."

Lakshmanan R, head of South and Southeast Asian corporate bonds at CreditSights in Singapore, said, "I think this is the beginning of a more sustained repricing of credit risk, the combined result of multiple global risks hitting the market in succession."

Meta's Massive Spending Plan Ignites Market Anxiety

The direct trigger for this round of credit market turmoil is Meta's latest capital expenditure plan disclosed this week.

Meta stated in its quarterly filing that the company is considering raising "hundreds of billions of dollars" over several years starting this autumn. Its spending commitments have climbed from approximately $700 billion in July to about $825 billion.

Meta also disclosed in the filing that its special committee views locking in capital ahead of others as a strategic priority, because it needs to complete financing "before competitors fill up all types of financing channels," and described the current environment as an "increasingly challenging financing environment."

This language further intensified market concerns about tech companies concentrating their fundraising efforts and crowding out a limited pool of capital.

SpaceX Borrows to Buy Chips, AI Financing Scale Continues to Break Records

Tech companies' borrowing ambitions extend beyond Meta. Elon Musk's SpaceX is seeking to raise $40 billion to purchase chips from Nvidia, a move that would rank among the largest debt financings in the history of AI buildout.

According to Semafor, citing people familiar with the matter, the financing rate will be higher than SpaceX's previous bond issuance, with lower-rated bonds priced at approximately 8.3%.

Bloomberg Trace data shows that as of Friday's close, the spread on SpaceX's 2046-maturity bonds with a 6.6% coupon widened by 13 basis points to 279 basis points.

According to data compiled by Bloomberg News, companies have raised more than $450 billion cumulatively in global debt markets this year for AI-related spending. John Lloyd, head of global multi-strategy and corporate credit at Janus Henderson in Denver, estimates that total debt issuance for AI buildout next year could approach $1 trillion.

Can the Market Absorb It? Divergence Emerges

Faced with the impending trillion-dollar financing wave, market participants hold differing views.

Lloyd said the market should be capable of absorbing this scale, and investors are not entirely unprepared for the coming issuance. But he also warned that market turbulence is inevitable: "The risks are widely known, so every data point can trigger volatility because it changes how the market weighs those risks."

The greater divergence lies in the return on AI investment itself. Ken Griffin, founder of hedge fund giant Citadel, warned that AI poses bubble risks; Blackstone President Jon Gray took the opposite stance, arguing that demand is growing "almost parabolically" and there is no need for excessive concern.

It is worth noting that despite the spread widening, the absolute level of U.S. investment-grade corporate bond spreads remains in a relatively low historical range, with 87 basis points notably below the roughly 109 basis point average of the past decade, indicating the market as a whole has not yet fallen into panic.

Strong Earnings Could Ironically Become a Risk Factor

A rather ironic market logic is taking shape: the more money tech companies make, the more investors may worry.

Both Meta and SpaceX reported results this week that beat analyst expectations, highlighting that these heavy borrowers can already generate excess profits before massive investments such as data centers are fully operational.

However, Travis King, head of U.S. investment-grade corporate bonds at Voya Investment Management, issued a warning. He said, "At the index level, spreads are still tightening, but beneath the surface it is a mess. If tech stock earnings deliver good news, the only implication may be that they will further expand their spending plans."

This means that strong earnings will not only fail to ease market concerns, but may instead set the stage for the next, even larger wave of borrowing.
