Total crypto market cap fell 12.6% in Q2 as stablecoin outflows and declining spot volumes signaled capital leaving the ecosystem, CoinGecko data shows.
Total cryptocurrency market capitalization declined 12.6% during the second quarter, falling by roughly $305 billion to $2.1 trillion, according to CoinGecko's 2026 Q2 Crypto Industry Report. The market ended June at its lowest level since September 2024, extending a third consecutive quarter of declines.
Stablecoin capitalization contracted for the first time since Q3 2023, slipping 1.6% to $305.1 billion. Average daily trading volume dropped 20.9% to about $93.1 billion, CoinGecko said.
ETF outflows, a hawkish Federal Reserve, and geopolitical tensions weighed on sentiment during June. A symbolic Bitcoin sale by Strategy added pressure.
Circle's USDC and Sky's USDS recorded the largest absolute declines as onchain yields fell. Tether's USDT held its ground, edging up its market share to 60%. Unlike previous downturns when investors often rotated into dollar-backed tokens, the latest figures suggest a portion of capital left the ecosystem entirely, according to the report.
Yet some segments drew activity. Derivatives trading held up better than spot markets. Prediction markets posted record volumes on major sporting events including the UEFA Champions League final, NBA Finals, Wimbledon, and the FIFA Club World Cup. Kalshi expanded its market share while Robinhood-backed Rothera emerged among the sector's largest platforms.
Hyperliquid's HYPE token entered the top ten cryptocurrencies by market capitalization after new exchange-traded funds, growing prediction market activity, and an expanded partnership with Coinbase.
Bitcoin lost 14.2% during the quarter. Ethereum fell 25.4%. Both underperformed U.S. equities.
The divergence shows a market where liquidity concentrates around products offering leverage, event-driven participation, or specific utility rather than lifting digital assets broadly, CoinGecko said.
The stablecoin contraction was the first since the third quarter of 2023, the report noted.
