An altcoin season is the period in which the majority of large cryptocurrencies beat Bitcoin over several months. That is not a mood and not a feeling but a ratio: an index counts how many of the largest coins have performed better than Bitcoin over a fixed window. If that ratio reaches 75 percent or more, the altcoin season counts as confirmed. On October 23, 2026 it sits clearly below that.
