Goldman Sachs' breakdown reveals that while S&P 500 companies' Q2 EPS year-over-year growth reached 45%, significantly exceeding market expectations, approximately 19 percentage points of this came from "other income" at Google and Amazon, primarily unrealized gains from equity investments. Excluding these non-operating gains, the S&P 500's Q2 EPS year-over-year growth was still about 26%, indicating that corporate fundamentals are not distorted, but earnings quality is changing and increasingly reliant on a few AI-benefiting companies. Concurrently, to support AI infrastructure investments, hyperscale tech companies' capital expenditures surged to $182 billion, while free cash flow during the same period was only about $5 billion, increasingly relying on debt and equity financing.
