Altseason Index Hits 9-Month High, Altcoin Market Cap Nears $1.64T

Altseason index readings climbed to 76 and then 78—the highest since December 2024—confirming that more than 76% of the top 50 cryptocurrencies have outperformed Bitcoin over 90 days. Data from Blockchain Center, CoinGlass and CoinMarketCap show the altcoin market cap (excluding BTC and stablecoins) surged to $1.63 trillion, nearing its late-2024 peak of $1.64 trillion. Bitcoin remains range-bound near $114,000, while leading altcoins such as DOGE, AVAX, XLM, LTC and TON posted daily gains of 3–18%, fueling risk-on sentiment and validating the altcoin rally. Analysts note that the altcoin market cap is approaching price-discovery territory. Prediction markets now price in a 50-basis-point Fed rate cut in September, which is expected to boost liquidity and spur further rally momentum. Traders are watching on-chain metrics, market-cap breadth and trading volume to confirm whether this momentum represents a sustainable altseason rather than a brief rotation. To prepare for the altcoin rally, traders are advised to set position limits, use trailing stops, monitor volume trends and reserve stablecoins for opportunistic buys. If history repeats, phase 3 of this altseason index surge could mirror the explosive growth seen in late 2021. Market breadth and rising altcoin market cap suggest a bullish outlook for altcoins.
Bullish
The news is bullish because the altseason index has reached its highest level in nine months, indicating broad altcoin outperformance. The altcoin market cap is nearing its late-2024 peak, and leading tokens are posting significant gains amid risk-on sentiment. Fed rate cut expectations further boost liquidity, likely fueling additional altcoin rallies. In the short term, traders may see momentum-driven price spikes, while sustained on-chain metrics and market breadth suggest a medium- to long-term bullish trend. However, traders should employ risk management to navigate potential volatility typical of late-stage altseasons.
