What is the Altcoin Season Index Value Today? When Will Altseason Come?

2025-07-22

When will altcoins finally outperform Bitcoin? Many crypto traders turn to the Altcoin Season Index, a popular tool that tracks whether top altcoins are outpacing BTC over the past 90 days.

By condensing market shifts into a single number from 0 to 100, this index reveals investor sentiment and signals whether we’re in “Bitcoin season” or heading into a full-blown altcoin rally.

What Is the Altcoin Season Index and How Is It Calculated?

The Altcoin Season Index is more than a catchy statistic. It is a market barometer built on comparative performance.

The formula is simple: if at least 75% of the top 50 altcoins have performed better than Bitcoin over the last 90 days, the market is considered to be in “altcoin season.”

Below that threshold, altcoin momentum is weaker and Bitcoin tends to lead.

This index is updated daily, relying on price data compiled from major exchanges and tracking services like CoinMarketCap.

The components shift regularly, removing stablecoins and wrapped tokens so the performance analysis centers only on “pure” altcoins.

Historical context adds nuance. For example:

The current yearly high for the Altcoin Season Index was 87, reached on December 4, 2024—a period marked by massive moves in smaller tokens and surges across altcoin sectors.
The yearly low was 12, recorded on April 26, 2025, during a sharp return of Bitcoin dominance.

These swings mirror changing market narratives, from periods of risk appetite and speculation to flights back to Bitcoin’s “safe haven” status.

Current Altcoin Season Index Value: Are We on the Edge of Altseason?

As of July 22, 2025, the Altcoin Season Index sits at 51.

This value signals a shift away from Bitcoin-dominated sentiment and toward renewed interest in altcoins.

While not yet at the classic “altseason” threshold of 75 or above, this midpoint shows altcoins are performing more robustly than they did in early June, or during last month’s low.

The recent surge is clear on the 90-day Altcoin Season Index chart, which shows a strong uptrend beginning in late June and accelerating in July.

The historical data shows yesterday’s index at 55, last week’s at 32, and last month at just 15—a rapid advance over a month, accompanying rallies across several altcoins.

This is further supported by the performance of the top 100 coins, where tokens like PENGU, SPX, CFX, and VIRTUAL posted triple-digit gains of over 100 percent in the last 90 days.

However, the transition to a true altseason is not automatic. Fluctuations around the current level suggest a market that is watching for cues—both from Bitcoin’s price behavior and broader crypto sentiment.

This standoff also sets the stage for dramatic moves if a clear narrative or catalyst emerges, such as regulatory news, large capital inflows, or significant upgrades to major altcoin ecosystems.

Key Drivers: What Triggers Altseason and Are We Close?

Altseason arises when a set of fundamental and technical factors align.

Historically, Bitcoin’s consolidation or sideways trading often serves as the backdrop for capital rotation into altcoins.

Other triggers include:

Increased speculative appetite, with retail and institutional investors seeking higher returns in smaller-cap coins.
Major developments or upgrades in leading altcoin platforms, generating hype and ecosystem liquidity.
Shifts in macroeconomic or regulatory environments, impacting Bitcoin dominance and risk sentiment.

Recent news points to a mixture of these factors in play. Reports highlight “altcoin season hopes” driving new momentum, alongside Bitcoin whales moving funds and signaling potential redistribution of capital toward alternative assets.

Looking forward, some analysts believe altseason could arrive if the Altcoin Season Index climbs above the 75 mark—something that occurred at the end of 2024, when a major rally swept through sectors like DeFi, gaming, and AI-related coins.

However, the current range-bound market may persist unless Bitcoin decisively enters a phase of low volatility, freeing traders to chase exponential upside elsewhere.

It is important to watch not just the index itself, but also money flows, volume trends, and market catalysts that could provide lift-off for the index and start a true altseason.

Market Opportunities and Risks as Altseason Approaches

A rising Altcoin Season Index brings both opportunities and risks.

For market participants, this period can reward those nimble enough to identify strong performers early—yet it also heightens the potential for price corrections and mispriced assets.

As the index climbs:

Top gaining altcoins tend to outperform dramatically. Over the past 90 days, coins such as PENGU, SPX, CFX, and VIRTUAL returned between 140% and 430%, highlighting the speculative energy that runs through altseason environments.
Market liquidity increases as more traders seek exposure beyond Bitcoin, often boosting smaller tokens and igniting sector-wide rallies.

Yet caution is warranted. Elevated volatility is common, with sharp pullbacks possible—especially when excitement outpaces fundamentals.

News-driven spikes can quickly reverse, and sudden profit-taking or negative headlines may sap momentum.

For both new and seasoned investors, tracking the Altcoin Season Index, monitoring volume and sentiment shifts, and applying basic risk management can help navigate these swings.

Periods when the index hovers between 50 and 75 often bring rotational opportunities, as traders attempt to position for the next major move or avoid being caught in rapid corrections.

Conclusion

The Altcoin Season Index today stands at 51—reflecting a market teetering between Bitcoin dominance and the opening moves of emerging altcoin leadership.

Recent trends and outlier performances among select tokens underscore building anticipation for altseason, but the index remains below the threshold that signals a true breakout.

Whether a full-fledged altseason arrives soon will depend on ongoing market rotation, Bitcoin’s stability, and external catalysts.

Investors who stay informed and cautious can seize opportunities as signals shift, while remaining mindful of the risks that come with increased volatility in altcoin markets.
