- Glassnode’s Altcoin Cycle Signal has flipped to Altcoin Season, reaching 86, as Bitcoin faces a drawdown.
- After nearly two years of altcoin selling pressure, the metric signals exhausted sellers on altcoins.
- The signal has historically preceded altcoin decoupling, raising questions of capital rotation into alts.
On June 22, 2026, Glassnode reported its Altcoin Cycle Signal hit 86, returning to Altcoin Season territory as Bitcoin (BTC) faces heavy drawdown. The shift is driven primarily by Bitcoin’s sharp decline rather than altcoin strength, with altcoins (alts) simply running out of sellers after nearly two years of pressure.
Glassnode’s Altcoin Cycle Signal Shifts to Altcoin Season
On-chain analytics platform Glassnode reported that its Altcoin Cycle Signal has shifted back into Altcoin Season territory, reaching approximately 86. This is well above the 50 threshold that separates altcoin-favoring conditions from BTC dominance.

The Altcoin Cycle Signal compares the relative performance of BTC against a broad basket of the top 250 altcoins (excluding stablecoins) by market capitalization. Values above 50 indicate conditions favoring altcoin outperformance, while values below 50 signal BTC Season. The metric updates daily based on price data.
BTC Drawdown Causes Signal Flip After Two Years of Altcoin Selling Pressure
In a typical altcoin season signal, altcoins rally while BTC holds steady or remains “bid.” The current flip is driven primarily by an opposite dynamic. Altcoins has faced nearly two years of consistent selling pressure following the previous cycle peaks. This exhaustion of sellers has left many altcoins more stable on a relative basis during the latest leg down, even as broader market sentiment remains cautious.
Glassnode highlighted the atypical nature of the current signal stating, “The typical version of this print has alts running while BTC stays bid. Currently, we see alts running out of sellers after nearly two years and BTC drawing down aggressively. For now, the BTC side is still doing most of the work.”

What’s Next for Altcoin Season and Market Rotation?
For this signal to translate into a sustained altcoin outperformance phase, several conditions need to align. BTC stabilization or recovery is key, as a genuine alt season typically emerges when BTC holds steady or rises modestly while capital rotates into altcoins. Continued sharp BTC drawdowns could keep the signal elevated but may also drag the broader market lower.
Analysts expect a more selective alt season in 2026 compared to previous cycles, with capital concentrating in high-conviction narratives rather than broad-based rallies. Historical patterns show altcoin rotations can move quickly once triggered, often lasting 4–12 weeks, though this cycle may be shorter due to institutional flows and ETF-driven market structure.
Meanwhile, other indices remain more cautious. The Blockchain Center Altcoin Season Index is currently around 51, still below the 75 threshold that confirms alt season, where 75% of the top 50 coins outperform BTC over a 90-day period. CoinMarketCap’s index is also lower at roughly 47, suggesting mixed signals across the market.
