Goldman: AI spending boost to S&P 500 profits fades after 2026

Goldman Sachs warned Sept. 19 that AI capital spending — now propping up S&P 500 earnings, the profits of 500 big U.S. firms — will wane after 2026. Chief U.S. equity strategist Ben Snider expects growth to slow, not collapse. With AI driving about 40% of 2026 earnings-per-share growth (profit per share), savers should watch if broader profits can take over.
