Prediction markets hit $113.8B record as crypto trading slumps

Prediction markets recorded $113.8 billion in notional volume during the second quarter of 2026, setting a quarterly record even as the wider cryptocurrency market contracted. The milestone highlights a divergence in digital asset demand, according to CoinGecko’s latest industry report. While traders pulled back from traditional crypto exposure, they poured capital into contracts tied to real-world events.

Total cryptocurrency market capitalization fell 12.6% to $2.1 trillion in Q2. Spot trading volume across the top 10 centralized exchanges dropped 27.9% to $1.95 trillion, down from $2.7 trillion in the first quarter. Perpetual futures volume on centralized platforms declined 10% to $12.7 trillion, and the stablecoin market cap slipped 1.6% to $305.1 billion. Decentralized exchanges mirrored the downturn, with the top 10 spot DEXs processing $408.9 billion, down from $556.4 billion.

The downturn concentrated market share among the largest players. Binance extended its dominance to capture 38.7% of the spot CEX market. MEXC suffered the steepest drop among major centralized exchanges, with its volume more than halving from $275.2 billion to $121.2 billion. In the decentralized sector, Uniswap held a 41.2% market share despite a 21.4% volume decline to $168.5 billion. The quarter also brought security challenges, with April marking a record month for DeFi hacks.

The surge in prediction markets was driven primarily by sports and politics. Monthly notional volume peaked at $50.7 billion in June, a 91.9% increase over the prior five-month average, coinciding with the start of the FIFA World Cup. Polymarket’s contract for the World Cup winner alone attracted more than $3.3 billion in volume. Contracts on the 2028 US presidential election also ranked among the platform's most traded.

Despite Polymarket's high-profile events, Kalshi maintained its position as the largest prediction market platform with a 58.9% market share. Polymarket's share fell from 35.8% to 30.2%, while Robinhood-backed Rothera Markets climbed to fourth place. This rapid expansion is attracting intense regulatory scrutiny. US regulators and states are locked in legal battles over whether to classify these platforms as financial markets or gambling operations, with lawsuits involving Kalshi escalating this year. Authorities in other jurisdictions are also imposing restrictions, citing gambling rules, market integrity, and insider trading risks.
