MSCI World: the top 10 already weigh 27.9% of the index

The MSCI World groups 1,249 large and mid-cap companies from 23 developed markets. It is the benchmark for a large share of global index funds.

As of September 30, 2026, the 10 largest holdings already account for 27.9% of the index. NVIDIA alone weighs 5.81%, and the Magnificent Seven together, 24.8%.

The practical reading: a global index fund is diversified by company count, but concentrated by weight. Out of every 100 euros invested in the index, about 28 go to just 10 companies.
