Altseason Is Postponed Again: Bitcoin Holds Nearly 59% of Crypto Market

There are still no signs of a broad shift of capital from Bitcoin to alternative cryptocurrencies, despite periodic rallies in individual tokens and Ethereum’s strengthening.

According to CoinMarketCap data as of September 12, 2026, the Altcoin Season Index stands at about 40 points out of 100, which is significantly below the 75-point threshold at which the market is considered to have entered a full-fledged altseason. Bitcoin’s dominance stands at about 58.7%, while Ethereum’s is 11.6%.

CoinMarketCap defines alt season as a period when at least 75% of the top 100 cryptocurrencies—excluding stablecoins and certain asset-backed tokens—have outperformed Bitcoin over the past 90 days.

BlockchainCenter’s alternative index also does not yet indicate an altseason: its value stands at around 33 points, while the required threshold is 75.

According to CoinGecko, the total market capitalization of the cryptocurrency market stands at approximately $2.76 trillion. Bitcoin remains the largest asset with a market capitalization of about $1.55 trillion.

Bitcoin’s high share indicates that a significant portion of new capital continues to be concentrated in the largest and most liquid crypto asset. This is driven by U.S. spot Bitcoin ETFs, corporate BTC purchases, and investor caution regarding less liquid tokens.

However, this situation differs from the classic cryptocurrency cycles of previous years, when, following strong growth in Bitcoin, capital would sequentially flow first into Ethereum, then into major altcoins, and finally into more speculative small-cap assets.

Certain altcoins have periodically significantly outperformed Bitcoin in the current cycle as well; however, so far these have been isolated instances rather than broad-based growth across the entire segment.

Ethereum has strengthened its position in recent months: its market share has grown from about 9% three months ago to around 11%, but this is not yet enough to trigger a full-scale rotation of capital away from Bitcoin.
