Crypto's total value fell $304.8 billion in the second quarter of 2026, a third straight losing quarter that dragged the sector to its lowest point since September 2024. CoinGecko's report puts Bitcoin and Ethereum at the center of the slide, while separate Glassnode data tracks roughly $28 billion in institutional outflows during June.
Total crypto market capitalization fell 12.6% in the second quarter of 2026, erasing $304.8 billion and leaving the industry at $2.1 trillion — its lowest level since September 2024. It was the third straight quarter in the red, roughly 52% below the October 2025 peak, according to CoinGecko's 2026 Q2 Crypto Industry Report.
June drove the quarter's losses
June delivered the hardest blow. A hawkish Federal Reserve, shifting US-Iran tensions, and a symbolic Bitcoin sale from Strategy pushed prices lower, the report said.
Bitcoin fell 14.2% over the quarter, while Ethereum dropped a sharper 25.4%. Both majors underperformed even as US equities staged a comeback, a clear split from traditional risk assets.
Average daily trading volume slid to $93.1 billion, down 20.9% from the prior quarter. Stablecoins followed the broader pullback for the first time since the third quarter of 2023, with the sector's market cap falling 1.6% to $305.1 billion.
Institutional money left the building
Separate data from Glassnode points to an institutional retreat. Net capital outflows reached $16.3 billion for Bitcoin and $5.8 billion for Ethereum, alongside $5.7 billion in stablecoin contraction during June — roughly $28 billion across major asset categories.
Drawing on data from more than 400 asset managers, the report found directional funds recorded broad losses while market-neutral strategies on average generated gains. US spot ETFs saw net outflows of 69,200 BTC and 292,900 ETH during June.
Prediction markets bucked the trend
Not every corner of the market retreated. Notional volume on prediction markets jumped 48.7% quarter over quarter to $113.8 billion, and June alone brought in $52.8 billion, an all-time high.
Kalshi grew its market share from 42.4% to 58.9%, while Polymarket's slipped from 35.8% to 30.2%. Hyperliquid's HYPE token broke into the top 10 by market cap on the back of new ETFs, growing prediction market activity, and a partnership with Coinbase.
