Apollo's Chief Economist Torsten Slok has raised concerns over the significant scale of debt issuance by AI hyperscalers, which could reach approximately $700 billion.

The ability of the market to absorb this substantial new supply remains uncertain, posing challenges for investors and policymakers.
