Altcoin Market Dominance — September 2026 Update

Current Market Overview — Around September 11, 2026

Bitcoin Dominance (BTC.D): ~57%–59%
Most common reading: around 58%–59%

Ethereum Dominance (ETH.D): ~10.9%–11.5%

Altcoin Season Index

The current Altcoin Season Index is around 33–37/100, indicating that the market is still in Bitcoin Season / No Altcoin Season territory.

A reading of 75+ is generally considered a strong Altcoin Season.

What Does This Mean?

Bitcoin still controls a large share of the total crypto market.

After the strong rally in August, BTC dominance has remained elevated or increased slightly in September.

This suggests that capital is still relatively concentrated in Bitcoin, while the broader altcoin market remains weaker.

Some individual altcoins, such as HYPE and ZEC, are showing strong performance, but the overall altcoin market has not yet clearly outperformed Bitcoin.

Historical Context

At the beginning of 2026, BTC dominance occasionally moved above 60%.

During Q2 2026, it dropped to around 55% at one point.

It has now returned to the 57%–59% range.

Bottom line: The broader market is not showing clear signs of a full-scale Altcoin Season yet. Bitcoin continues to maintain a strong dominance, while altcoin strength remains selective
