Crypto market cap fell 12.6% to $2.1 trillion, lowest since Sept 2024. Bitcoin dropped 14%, Ethereum 25%. Trading volumes plunged 21% QoQ. Prediction markets surged 48.7% to $113.8B.
The second quarter of 2026 extended crypto's bear market into a third straight quarter of decline. Total market capitalization dropped 12.6%, shedding $304.8 billion to end at $2.1 trillion. The market hit its lowest point since September 2024, roughly 52% below the October 2025 peak. June delivered the sharpest correction of the year.
The June plunge followed ETF outflows, a hawkish Fed stance, and shifting US-Iran tensions. A symbolic Bitcoin sale by Strategy added to the pressure. Bitcoin fell 14.2% during the quarter. Ethereum dropped 25.4%. Both continued to decouple from US equities, which staged a strong recovery over the same period. The divergence between struggling majors and pockets of speculative altcoin demand widened. Hyperliquid's HYPE token broke into the top 10 on the back of new ETFs and a Coinbase deal.
Trading activity cooled for a second consecutive quarter. Average daily volume fell to $93.1 billion, a 20.9% quarter-on-quarter decline. Spot centralized exchange volume among the top 10 dropped 39.1% to $1.95 trillion. Monthly volume hit a low of $619 billion in May before a modest June rebound to $695 billion.
Binance extended its dominance with 38.7% of spot market share. Bybit was the only other exchange with a double-digit share at 10%, displacing MEXC. MEXC saw the biggest slump among top exchanges – volume more than halved from $275.2 billion to $121.2 billion, dropping its ranking from second to seventh. Crypto.com and KuCoin also fell sharply, down 40.9% and 38.5% respectively.
Perpetual futures held up better than spot. The top 10 perp exchanges recorded $12.7 trillion in volume, down 10% from $14.1 trillion in Q1. Monthly volume stayed above $4 trillion, still above the averages for the first three quarters of 2024. Traders favored perps over spot, the report showed, with perps volume declining only 10% versus spot's 39%. Growth in real-world asset perpetuals also helped maintain interest. Relative market share among the top 10 perp exchanges stayed largely unchanged. MEXC recorded a brief surge in April and early May. Those gains faded by June.
The stablecoin sector contracted for the first time since Q3 2023. Total market cap fell $4.8 billion, or 1.6%, to $305.1 billion. Circle's USDC posted the largest absolute outflow, dropping 4.8% ($3.7 billion) to $73.5 billion. Tether's USDT held roughly steady, rising 0.2% ($0.3 billion) to $184.4 billion, increasing its market share to 60%. Sky's USDS fell 16.4% ($2 billion) to $10 billion, reversing its prior quarter's momentum. Ethena's USDe resumed its contraction after a brief Q1 stabilization, dropping 24.4% ($1.4 billion) to $4.4 billion. The drop was driven by a compression in yield that fell below the risk-free rate, prompting sUSDS and sUSDe stakers to unstake.
Prediction markets were a bright spot. Notional volume totaled $113.8 billion in Q2, up 48.7% from Q1. June alone saw $50.7 billion, a 91.9% increase from the average of the previous five months and a new all-time high. The surge came from a concentration of major sporting events starting in late May – the UEFA Champions League Final, the Stanley Cup, the NBA Finals, the FIFA World Cup, and Wimbledon.
Polymarket saw Sports contracts jump from 40% of its volume in January to 81% in June. Kalshi increased its lead in market share from 42.4% in Q1 to 58.9% in Q2. Polymarket's share fell from 35.8% to 30.2%. Rothera, the Robinhood and Susquehanna International Group joint venture launched in May, rose to fourth place in June with $2.1 billion in notional volume.
The tokenized trading card game space saw a shift. Collector Crypt surpassed Courtyard as the top platform, recording a 317% increase in monthly volume from $97 million in January to $406 million in June. It now holds 62.8% of volume share. OpenSea recorded only $32.7 million in NFT sales in June. Collector Crypt and Courtyard recorded far higher volumes. Most of these platforms' volume comes from 'gacha' mechanisms – randomized NFT purchases – not secondary sales. On average, over 98% of a platform's transaction volume is generated through this feature.
