Key Takeaways

This chart shows all 500 companies in the S&P 500, sized by market cap and grouped by sector.
Nvidia, Apple, and Microsoft alone make up about 18% of the $57.6 trillion index.
A small group of mega-cap companies occupies a disproportionate share of the market.

What does the entire S&P 500 actually look like?

This visualization brings all 500 companies into a single view, with each sized by its share of the index and grouped by sector. It is based on data from Slickcharts as of March 30, 2026.

Each circle represents a company, making it easy to compare how market value is distributed across sectors—and to see which firms dominate the index.

One immediate takeaway is how much space is occupied by just a handful of companies. Just 10 firms now make up over 36% of the S&P 500, up from 23% in 2000.

Ranked: The Top S&P 500 Companies by Index Weight

Nvidia is now the largest company in the S&P 500, with a 7.0% index weight—larger than entire sectors like energy or utilities.

Apple follows with a 6.3% share, while Microsoft ranks third at 4.6%. These three companies account for about 18% of the S&P 500’s total value, while AI-driven firms represent 10 of the top 20 largest companies.

Berkshire Hathaway is the only financials company in the top 10 by market cap, with its ranking falling from sixth to 10th place since 2023. By contrast, Walmart has climbed to 11th from 29th in just two years amid strong online sales.

Among health care firms, Eli Lilly (#12) has overtaken UnitedHealth Group (#42) as the most valuable company, fueled by sales of its weight-loss drugs.

Why This Concentration Matters

While the top 10 companies’ share of the index has edged down from 41% in 2025, its still-elevated concentration relative to historical levels has real implications:

Diversification is shrinking: Index investors are more exposed to a handful of companies than at previous market-cycle peaks
Market performance is narrowing: A small group of firms is increasingly driving overall returns
The index is evolving: The S&P 500 may no longer broadly reflect the U.S. economy

In effect, the market is behaving less like a 500-company index, and more like a concentrated bet on a few dominant firms. At the center of this shift is the AI boom, illustrating how a single technological wave is reshaping the market’s hierarchy.
