Altcoin Market Cap Closes August Above $1 Trillion: What Comes Next?

The total market capitalization of altcoins, excluding Bitcoin and Ethereum, closed in August above $1 trillion, a key milestone. The monthly close, by trader Ash Crypto, signals that altcoins may be on the verge of a major breakout as the market enters the final quarter of 2025.

Data from TradingView shows the monthly chart of the altcoin market cap (TOTAL3) closing at $1.03 trillion, with a high of $1.04 trillion and a low of $999.95 billion during August trading. This marks the first sustained close above the $1 trillion threshold since 2021.

The chart indicates that $1.1 trillion has acted as long-term resistance, capping gains in both 2021 and 2024. The monthly close above this level would confirm strength and potentially trigger a move toward the $1.3 trillion to $1.5 trillion range. Notably, altcoins have been in an uptrend since late 2022, when the market bottomed near $300 billion.

Meanwhile, a rejection at current levels remains a risk, with support expected near $910 billion if momentum weakens. However, traders view the latest monthly close as a constructive signal for the broader altcoin market. “Q4 will be huge for alts,” Ash Crypto noted. This suggests that capital may shift into smaller-cap digital assets soon.

In a separate analysis, Kiri, the “FX Professor” that altcoins are setting up for a critical test at the $1.12 trillion mark. The total crypto market cap excluding Bitcoin and Ethereum (TOTAL3) remains within a long-term ascending channel, with the $1.12T level having already caused two strong rejections. A third test at this level could either confirm a breakout or trigger a pullback.

The analyst also noted that the broader macroeconomic environment appears supportive, with the S&P 500 holding above key resistance, interest rate cuts expected in September, and Bitcoin and Ethereum maintaining their strength, particularly Ethereum.

As a projection, the analyst noted that if TOTAL3 breaks through $1.12 trillion, targets could reach $1.39 trillion to $1.51 trillion. Meanwhile, a rejection could see a return to the lower channel boundary near $898 billion.

Interestingly, analyst Nobler the “Golden Altseason of 2025” kicking off this month.

He noted that altcoin rallies follow repeatable patterns, recalling how he turned $450 into $210,000 during the 2021 cycle. This year, he plans to capitalize even more on high-potential new altcoins as he expects the altcoin market to surge by 200X compared to 125X to 150X in the past cycles.
