Altcoin Season Could Kick Off In September

Altcoin season could start in september – coinbase forecast

Coinbase Institutional’s latest report suggests that altcoin season could begin in September 2025. David Duong, Coinbase’s global head of research, highlights three key drivers: declining Bitcoin dominance, improved market liquidity, and capital rotation into higher-risk assets.

Bitcoin dominance drops – capital flows into altcoins

Bitcoin's market share has fallen from over 65% to around 59%, signaling that investors are shifting capital from BTC to promising altcoins in search of greater returns.

Altcoin market cap rises sharply

Since early July, the altcoin market cap has surged by over 50%, while trackers like CoinMarketCap’s Altcoin Season Index and Blockchain Center’s indicator are trending upwards, though still below the 75 threshold that historically confirms a full altseason.

Ethereum leads the shift

Ethereum is at the forefront of this trend, driven by strong demand from digital asset treasuries and growing interest in stablecoins and real-world assets (RWA). Related tokens like Arbitrum, Lido DAO, and Optimism are also gaining momentum.

Market conditions align for alt season

With BTC dominance declining, stablecoin-driven liquidity improving, and expectations for a Federal Reserve rate cut, Coinbase believes the stage is set for altcoin season to kick off in September.
