CoinGecko's Q2 2026 Crypto Industry Report puts total market capitalization at $2.1 trillion by the end of June, a drop of $304.8 billion, or 12.6%, from the previous quarter. That marks the third consecutive quarterly decline and the weakest reading since September 2024, sitting roughly 52% below the peak reached in October 2025.
Bitcoin lost 14.2% over those three months. Ethereum fared worse, shedding 25.4%. Average daily trading volume across the market fell 20.9% quarter-on-quarter to $93.1 billion. April was actually one of the stronger months of the year, but momentum flipped hard, with June absorbing the bulk of the damage. CoinGecko points to a cluster of triggers: rising ETF outflows, a hawkish Federal Reserve, swings in US-Iran tensions, and a symbolic Bitcoin sale by Strategy.
Stablecoins crack for the first time in three years
The stablecoin sector contracted by $4.8 billion, or 1.6%, closing Q2 at $305.1 billion. It was the first quarterly shrinkage since Q3 2023. Circle's USDC took the hardest hit in absolute terms, dropping 4.8% to $73.5 billion. Tether's USDT barely moved, up 0.2% to $184.4 billion, which pushed its market share to 60%. Sky's USDS fell 16.4% and Ethena's USDe slid 24.4%, both casualties of yield compression that dropped below the risk-free rate.
Exchanges lose ground, prediction markets go the other way
Spot trading volume on the top 10 centralized exchanges dropped 27.9% to $1.95 trillion. May was the low point at $619 billion before a partial rebound to $695 billion in June. Binance held its ground with a 38.7% market share. MEXC had a rougher ride: its volume more than halved, knocking it from second place down to seventh. Perpetual futures volume fell 10%, from $14.1 trillion in Q1 to $12.7 trillion in Q2.
Prediction markets bucked every trend in the report, with notional volume growing 48.7% against the broader contraction across all other segments.
BTC and ETH both ticked lower in the hours after the report dropped.
