The Altcoin Season Index (ASI) is stuck at 36 this week, well below the 75 threshold that historically marks the start of a genuine alt season. Meanwhile, Bitcoin dominance climbed to 59.88% over the weekend, a move that usually runs counter to any rotation into smaller tokens. The numbers paint a clear picture: the market isn't tilting toward altcoins yet, even if a few names are pumping.
The 36 reading
The ASI measures how many of the top 100 altcoins have outperformed Bitcoin over the past 90 days. A reading above 75 means at least 75% of those coins are beating BTC — the classic signal for alt season. At 36, that's not even close. The index has been hovering in this range for weeks, and the weekend's dominance jump only reinforced the status quo.
Why Ethereum matters
Ethereum is underperforming Bitcoin right now, which historically precedes the start of an alt season. In past cycles, ETH strength was the leading indicator — once ETH started to catch up, capital would flow further down the market cap ladder. That hasn't happened. ETH relative weakness suggests the broader market is still betting on BTC as the safe play.
Hyperliquid's rally in context
Hyperliquid hit a new all-time high recently, and that's grabbed headlines. But the data says it's a temporary spot rally, not the start of a sustained shift. Isolated pumps happen even in a bearish or neutral environment. Without broader participation — and without ETH turning around — these moves tend to fizzle. This one doesn't look different.
What to watch next
For a real alt season to begin, the ASI needs to cross 75 and stay there. That would require a sustained drop in Bitcoin dominance and a clear outperformance from Ethereum. Neither is happening now. Until those conditions line up, the market is waiting — and the odds remain stacked against an imminent rotation.
