Bridge from traditional non-tech corporate refinancing to hyperscaler AI and utility grid tranches
Goldman Sachs syndicate desk estimates that hyperscaler compute expansion now generates an annualized debt-funding overhang of $173B, elevating annual US IG supply from $1,350B to $1,520B. With power utility balance sheets absorbing an incremental $65B to interconnect nuclear and turbine capacity, dealer concession premia widen 10Y benchmarks by +18 bps, pushing aggregate corporate hurdle rates up to 6.12%.
