Has an altcoin season started in the cryptocurrency market? The altcoin season index may be giving a clue about this.
According to CoinMarketCap Altcoin Season Index data, the cryptocurrency market is currently in a clear Bitcoin Season.
The index value is only 24 out of 100. This value shows that Bitcoin’s performance in the last 90 days has been better than most altcoins. The annual peak was recorded as “Altcoin Season” on December 4, 2024, at 87; however, on April 26, 2025, this value fell to the annual low of 12.
Despite this, some altcoins have managed to outperform Bitcoin in the last 3 months. Here are the prominent altcoins that have outperformed Bitcoin (30.10%) in the last 90 days and their rate of rise:
Particularly, the significant value gains of relatively new or speculative coins such as SYRUP, PENGU and HYPE give the impression that we are on the verge of an altcoin season.
However, the fact that the CMC Altcoin Season Index is still at low levels reveals that the overall market has not yet fully turned in favor of altcoins.
