Semiconductor Stocks Take the Lead in S&P 500 Earnings Growth
Technology remains the main engine behind S&P 500 profit growth, but the leadership is starting to shift.
In the first quarter of 2026, major hyperscalers such as Amazon, Alphabet, Meta, and Microsoft contributed around 34% of the index’s year-over-year EPS growth. Semiconductor companies added another 31%.
Together, these two groups generated roughly 65% of total S&P 500 earnings growth. That was well above their 52% contribution in the first quarter of 2025. The rest of the index accounted for only around 36%, based on rounded figures.
The balance may change further in the second quarter. JPMorgan expects semiconductor companies to contribute a record 48% of EPS growth. The hyperscalers’ share is projected to fall sharply to around 9%.
