Consensus estimates for S&P 500 earnings growth in 2026 have increased from about 15% to roughly 24%, with Goldman Sachs projecting operating EPS near $340 in 2026 and $385 in 2027. This growth is partly structural due to a tech-heavy index with higher profit margins, but much of the recent surge is driven by a small group of AI-focused companies. Margins tend to revert to the mean, and the main risk to earnings growth is a slowdown in AI-related capital spending, which is already showing early signs. Investors should watch for this potential earnings mean reversion, which is not necessarily tied to a recession but to changes in AI investment dynamics.
Earnings mean reversion and estimate changes provide context for market watchers.
