Bitcoin’s Share in Top 100 Crypto Assets Excluding Stablecoins Rises to 67%: 5-Year Peak

Concentration in cryptocurrency market capitalization has returned to 2021 levels among Top-100 assets excluding stablecoins.

The total market capitalization of the top 100 crypto assets excluding stablecoins is increasingly concentrating in a narrower group of large assets rather than spreading across a wider altcoin base. Data from CryptoRank dated September 10, 2026, shows that the share of the seven major crypto assets referred to as the MAG7 has risen to 92.1%.

This ratio covers the total market capitalization of Top-100 crypto assets excluding stablecoins. While the MAG7’s share was at 91% in 2021, it dropped to 80.2% in 2022, only to rise again every year thereafter. The share reached 85.9% in 2023, 86.1% in 2024, and 88.5% in 2025.

Bitcoin’s Share Within the Top-100 Rises to 66.6%

The most prominent part of the concentration was Bitcoin. Bitcoin’s share in the same metric reached 66.6%, hitting its highest level in the last five years. This ratio was recorded as 56.7% in 2021, 44.9% in 2022, and 50.2% in 2023.

Bitcoin’s share rose to 56.7% in 2024 and 61.7% in 2025. Thus, while the weight of both Bitcoin and the MAG7 group in the total market capitalization increased, the share of the broader altcoin market narrowed.

CryptoRank data indicates that market growth is relying more heavily on a small number of large crypto assets.
