Man Group Warns of Bubble Risk as AI Bond Sales Hit Record Levels
0xBroomberg
Man Group, the world's largest listed hedge fund, warns that the AI infrastructure race is driving record bond issuance and creating bubble risk — with the scale set to dwarf the 2001 dot-com peak.
How big is the AI bond wave?
Citing Morgan Stanley estimates, Man Group says AI and hyperscale cloud-related bond issuance could reach $400 billion in investment-grade and $65 billion in junk-rated debt.
Combined, that would account for nearly 20% of all bond issuance.
This means → roughly one in every five dollars raised in the bond market is now tied to AI — concentration is already very high.
How does this compare to the dot-com bubble?
At the 2001 dot-com peak, tech-sector bond issuance totaled $85 billion, averaging 14.5% of total issuance across 2000–2001.
Today, AI-related junk bonds alone nearly match that entire figure; investment-grade issuance is several times larger.
In plain terms = the dot-com bubble's footprint in the bond market looks like a rounding error next to today's AI debt wave.
What worries Man Group the most?
The core concern targets the high-yield and leveraged-loan markets — loans extended to already heavily indebted companies at floating rates — where many borrowers remain persistently free-cash-flow negative.
In plain terms = these companies are borrowing money while their operations keep burning cash. Debt repayment depends on continued refinancing — if the market tightens, the chain can snap.
Sriram Reddy, Man Group's head of client portfolio management, said market enthusiasm has produced "clear signs of overextension."
Can returns support the debt?
Man Group flags a fundamental uncertainty: the return profile of AI investment remains unproven, a problem most acute among lower-rated emerging cloud and data-center operators.
This means → more and more companies are borrowing to build data centers, but who can actually generate enough AI revenue to service that debt is still an open question.
Higher leverage ratios and capital intensity add further risk — the faster the build-out, the greater the execution risk.
What does this mean for investors?
Man Group's conclusion: given the execution risk embedded in such rapid expansion, investor caution is warranted.
This reflects a deeper signal — even if AI technology itself has a bright future, the credit market financing it may not safely absorb this speed and scale.
In plain terms = the technology may be right, but if debt accumulates faster than returns materialize, the bubble can burst first.
