These mega-cap stocks are grouped together due to ranking among the largest tech companies (although some are technically part of other market sectors) and because of their connections to AI.

The Magnificent Seven accounted for 33.9% of the S&P 500 in August 2026, according to data sourced from Stock Analysis. Their combined weight relative to the S&P 500 index has been fairly steady, typically ranging from 32% to 35% over most of the last year.

The S&P 500 is often used as a measure of the average stock market return, and the Magnificent Seven are significantly more volatile -- for better and for worse. Collectively, they've underperformed the S&P 500 in 2026, but outperformed over the trailing one-year period. Returns vary quite a bit within the Magnificent Seven, as Amazon has led the pack this year while Tesla has plummeted.

|---|---|---|
Apple | 15.25% | 42.4% |

The overall composition of the Magnificent Seven has shifted over the last decade. Nvidia is the biggest story, growing from less than 1% of the total Magnificent Seven market cap in 2015 to now being the largest contributor, accounting for more than 22% of it, according to market capitalization data from Stock Analysis and Yahoo! Finance.
Investors who buy S&P 500 index funds sometimes worry about the index's top-heavy composition. It's a logical concern, given that seven AI stocks contribute over one-third of the index's value.
However, anyone invested in the S&P 500 has shared in the Magnificent Seven's success, particularly during the periods when this group drove most of the index's returns.
The Magnificent Seven's stock percentage of the S&P 500 ultimately depends on how the group performs. They make up a large portion of the index because they've outperformed. When they lag the market, as they had through the first half of 2026, the index rebalances accordingly.
