Hyperscaler Credit Hinges on AI Cash Flow Bet

Apollo Global Management's chief economist Torsten Slok warns that the credit case for hyperscalers, Alphabet, Meta, Amazon, Microsoft, and Oracle, hinges on a single assumption: their combined operating cash flow will triple from $600B to $2T. This forecast is widely shared among investors, who have financed an unprecedented capital-expenditure cycle with debt as free cash flow turned negative.

The markets have accepted this leverage, expecting AI-related revenues to generate a sharp rebound in cash generation. However, Slok argues that if this rebound fails to materialize, the consequences will not be confined to a handful of technology balance sheets. Instead, investor appetite for the broader AI trade could fade, credit spreads on hyperscaler debt would likely widen, and companies may need to scale back spending plans.

The note frames this assumption as the single point of consensus holding the credit story together. While it does not forecast a miss, it makes the downside path explicit: weaker cash conversion would first hit valuations and funding costs, then investment, and finally the real economy.
