- Altcoin Season Index surges to 84, the strongest altcoin dominance since late 2024.
- Analyst James Bull expects retail driven altseason activity to intensify in October with fast inflows.
- Historical data shows altcoin seasons average 17 days, with some extending up to 117 days.
The Altcoin Season Index has reached 84, its highest level since December 2024, confirming a strong phase where altcoins outperform Bitcoin. According to analyst James Bull, this rare event may lead to a new wave of speculative inflows from retail traders.
Historical data shows Bitcoin has maintained dominance far more frequently, with 953 days in Bitcoin Season compared to just 407 for altcoins. However, the latest surge shows a clear rotation of capital into alternative assets.
Altseason Index Shows Rare Highs
The index, which defines altcoin dominance once it rises above 75, shows a broad change in market behavior. The current reading of 84 surpasses the level and supports accelerating momentum across multiple assets. The last comparable level appeared in late 2024 before the market cooled sharply into early 2025.
Data further reveals that altcoin seasons are historically shorter than Bitcoin cycles. On average, altcoin phases last 17 days compared to Bitcoin’s 10. However, the longest streak for altcoins stretched to 117 days, suggesting that extended runs remain possible if current conditions persist.
Analyst Outlines Phases of Upcoming Cycle
James Bull described the early signals as a prelude to larger market shifts. He noted that retail investors often begin with small entries, like $100 in wallets such as Phantom. Once these initial bets multiply, traders typically increase allocations to higher amounts, driving liquidity into smaller tokens.
According to Bull, this escalation may intensify in October. He expects a period where traders push $5,000 increments into newly launched projects several times daily. This behavior, he said, has historically aligned with peak altseason conditions, where portfolios reach six figure levels in a short span.
Historical Context and Market Rotation
Bitcoin recently completed its dominance phase, which ended 65 days ago, creating room for altcoins to rise. The current trend began in June 2025, when the index stood below 30, indicating Bitcoin control. From that point, the index climbed steadily, a decisive rotation toward altcoins.
Cycles often feature sharp reversals. In previous cases, once Bitcoin regained strength, many altcoins had fast dips of up to 90 percent. Historical records also confirm that altcoin cycles end faster, indicating the importance of timing during such rare surges.
