The cryptocurrency market ended the second quarter of 2026 with a total capitalization of US$2.1 trillion, down 12.6% from Q1 , according to CoinGecko's quarterly report published this Thursday (16). The number represents the lowest level since September 2024 and puts the market 52% below the all-time high reached in October 2025.
This marks the third consecutive quarter of decline. The worst moment occurred in June, when the Fed's hawkish stance, US-Iran tensions, and Strategy 's symbolic Bitcoin sale combined for the biggest pullback of the year.
Bitcoin and Ethereum disappointed while stocks rose.
The most revealing piece of data in the report is not the market downturn. It's the decorrelation with traditional assets.
Bitcoin retreated 14.2% and Ethereum dropped 25.4% in Q2, even as US stocks registered a strong recovery. In previous cycles, Bitcoin tended to rise along with risk assets when market appetite improved. In Q2, the correlation broke in the wrong direction for crypto holders.
Bitcoin is down 50% from its October 2025 high of $126,080 and, at certain points in June, retested the $58,000-$60,000 range. Ethereum suffered proportionally more, reflecting both widespread selling pressure and outflows from ETH ETFs.
Stablecoins retreated for the first time since Q3 2023.
The total market capitalization of the stablecoin sector fell 1.6%, or $4.8 billion , in Q2 2026, ending the period at $305.1 billion. This was the first decline since Q3 2023.
This movement is significant because stablecoins function as a liquidity reserve within the crypto ecosystem. When their total value falls, it means that capital is leaving the system, not just being reallocated between assets.
The dynamics by issuer were uneven. Circle's USDC registered the largest outflow in absolute terms, falling 4.8% to US$73.5 billion. Tether's USDT remained virtually stable , rising 0.2% to US$184.4 billion, expanding its market share to 60%.
Among the most significant losers are Sky's USDS, which fell 16.4%, and Ethena's USDe, which retreated 24.4%, both pressured by yield compression that fell below the risk-free rate.

The positive highlight: forecast markets exploded.
Amid the overall decline, one segment experienced significant growth. Notional volume in forecast markets totaled US$113.8 billion in Q2 2026, a 48.7% increase compared to Q1. June's volume reached US$50.7 billion, a 91.9% increase compared to the average of the previous five months, marking a new historical record.
The catalyst was sports: the concentration of major events since the end of May, including the Champions League final, the NBA Finals, the Stanley Cup, Wimbledon and the World Cup, transformed the month of June into an unprecedented peak of activity in the prediction markets.
On the Polymarket platform, sports contracts came to dominate volumes, representing 81% in June compared to just 40% in January . In terms of market share, Kalshi extended its lead from 42.4% in Q1 to 58.9% in Q2, while Polymarket fell from 35.8% to 30.2%.
Rothera, a joint venture between Robinhood and Susquehanna International Group launched in May, quickly rose to fourth place with $2.1 billion in notional volume in June.
HYPE enters the top 10 and becomes the standout asset of the quarter.
While the overall market retreated, HYPE, Hyperliquid's native token, broke into the top 10 by market capitalization. The move was driven by new ETFs, growth in the prediction markets integrated into the platform, and an agreement with Coinbase.
HYPE is the same asset that appears in Mercado Bitcoin 's July portfolio recommendations and that the Binance Research report points to as one of the most relevant in terms of perpetual volume.
Entering the top 10 during a quarter of widespread decline reinforces the argument that decentralized derivatives and prediction platforms are the segment with the most traction in the crypto ecosystem in 2026.
Centralized exchanges: volume plummeted.
Spot trading volume on the top 10 centralized exchanges fell 27.9% in Q2, from US$2.7 trillion to US$1.95 trillion. May recorded the lowest monthly volume of the year, with only US$619 billion.
Binance maintained its lead with a 38.7% market share. MEXC experienced the largest drop, with volume falling by more than half, from US$275.2 billion to US$121.2 billion, and its ranking falling from second to seventh place.
In the perpetual securities segment, the decline was smaller. The volume of perpetual securities on the top 10 centralized exchanges fell 10% in Q2, from US$14.1 trillion to US$12.7 trillion. The smaller decline compared to the spot market reflects traders' preference for leveraged speculation, in addition to the growth of RWA perpetual securities.
What to expect from Q3
The CoinGecko report doesn't make explicit projections, but the data points to a market that has yet to find catalysts for structural recovery. The hawkish Fed, the decorrelation with stocks, and outflows from ETFs are the three main obstacles.
The growth drivers identified in Q2, forecast markets, RWA, and decentralized derivatives platforms like Hyperliquid, provide indications of where the capital that remained in the ecosystem is concentrating.
