The Altcoin Season Index, closely followed by investors in the cryptocurrency market, provides a clear picture of the current market outlook.
According to CoinMarketCap data, the index is calculated based on 90-day performance and reveals the distinction between Altcoin Season and Bitcoin Season.
According to current data, the index is at 21. This value clearly indicates that the market is in a Bitcoin Season. According to the index methodology, an Altcoin Season is declared if more than 75% of the top 100 cryptocurrencies outperform Bitcoin in the last 90 days. However, the current situation is far from this.
The index, which signaled a Bitcoin season at 21 the day before, was measured at 16 last week and 25 last month.
An even more striking comparison emerges when examining the annual data. The Altcoin Season Index, which rose to 78 on September 20, 2025, indicated a strong altcoin season. However, on April 26, 2025, the index fell to 12, recording its lowest point of the year. The current level of 21 shows that the market has not yet fully emerged from this weak zone.
The performance of the top 100 cryptocurrencies over the last 90 days also aligns with the index data.
Here are all the major altcoins that have outperformed Bitcoin in the last 90 days, along with their growth rates:
