Glassnode Flips Bullish on Altcoins: Is Altcoin Season Finally Here?

After months of price action primarily driven by Bitcoin, the altcoin market has entered a more significant phase in 2026. Glassnode's latest signal has turned positive in favor of altcoins, indicating that relative momentum is moving beyond the largest cryptocurrency.

The altcoin cycle signal from Glassnode has shifted from a bias towards Bitcoin to altcoins. Unlike a rally in isolated altcoins, this move appears to be broadening as market participation has increased. This development offers additional validation that the crypto market could be witnessing a rotation.

Breadth is improving across the market, with price action reflecting gains spreading out across multiple sectors and market-cap sizes. This suggests that the latest rally looks different from what took place in August, when Bitcoin drove the majority of the price action and numerous altcoins failed to match its strength.
