AI boom lifts its own cost of capital: hyperscaler debt spreads widen ~25bps this year

Citing a piece from The Information, Rohan Paul argues the AI boom is raising its own cost of capital: hyperscalers' flood of bond issuance has made their debt pricier relative to other top-rated companies.

Key data point: the extra yield investors demand to hold hyperscaler debt has risen by about 0.25 percentage points this year.

His core thesis: the physical bottleneck (compute) is turning into a financing bottleneck — as giants pile into debt to fund data centers, bond markets are repricing that risk, making AI expansion more expensive to fund.
