Altseason 2026: why the Altcoin Season Index and TOTAL2 are telling a very different story

Everyone keeps asking when the next altseason will arrive, but some of the core indicators are flashing a very different signal this cycle.

TOTAL2 (total crypto market cap excluding Bitcoin) hasn’t produced a sustained breakout after the 2024 halving like it did in previous cycles. At the same time, [CoinMarketCap’s Altcoin Season Index](https://coinmarketcap.com/charts/altcoin-season-index/) has spent most of the cycle in Bitcoin-dominant territory, with only short and shallow spikes toward “altseason” levels.

Instead of a broad rotation from BTC into hundreds of altcoins, capital flows seem to be concentrating in a narrow set of assets — mainly BTC, ETH, and a few ETF-eligible tokens. It starts to feel less like a delayed altseason and more like a structural change in how this market works.

Curious what others think — is altseason just late, or is the classic 4-year model finally breaking?
