Summary

Goldman Sachs analysis indicates that hyperscalers such as Amazon, Microsoft and Google would need to generate roughly $1 trillion in additional revenue for their massive AI capital expenditures to earn a 15% return. The calculation directly ties AI infrastructure spending to the revenue that must eventually materialize, highlighting the large gap between current outlays and income.

Bubble analysis

This is core evidence in the bubble debate: it puts a number on how far AI capex is running ahead of the revenue AI actually generates today. Investors must first believe that roughly a trillion dollars of new revenue will eventually appear for today's spending to pay off, so the return hinges entirely on income that does not yet exist.
