The cryptocurrency market is receiving contrasting signals from two widely followed on-chain metrics. CoinMarketCap’s Altcoin Season Index fell to 45 on July 4, 2026, down three points from the previous day, indicating a tilt toward Bitcoin dominance. The index, which tracks whether 75% of the top 100 crypto assets (excluding stablecoins and wrapped tokens) have outperformed Bitcoin over the trailing 90 days, sits well below the 75 threshold for a confirmed altcoin season. A reading of 45 means fewer than half of the top altcoins have beaten Bitcoin’s returns, placing the market in a neutral-to-Bitcoin-dominant zone.
Meanwhile, on-chain analytics firm Glassnode released a contemporaneous report stating that its Altcoin Cycle Signal still points to an active altseason with genuine momentum. This contradicts the simple narrative of a Bitcoin comeback. Glassnode had earlier flagged the ‘denominator effect’ – a phenomenon where altcoins appear to gain ground merely because Bitcoin’s price is stagnant or declining. The firm now clarifies that the current altcoin strength has moved beyond that illusion, with both relative and absolute performance metrics showing real capital inflows into the broader altcoin market, not just a rotation out of Bitcoin.
These diverging indicators highlight a transitional phase. Historically, a sustained CMC Altcoin Season Index below 40 has preceded market corrections or prolonged Bitcoin dominance, while readings above 75 coincide with risk-on altcoin rallies. Glassnode’s signal, which incorporates realized capitalization, network activity, and investor behavior, suggests the current environment may be more nuanced. Traders are now weighing the possibility of a ‘Bitcoin season’ against structural strength in the altcoin sector driven by developer activity, DeFi/NFT growth, and anticipation of regulatory clarity. The data does not offer a clear directional call, reflecting a market in flux.
