Volume Breaks Records as Non-Sports Trading Surges
Prediction markets achieved a milestone in the last week of June 2026, with single-week trading volume exceeding $14.4 billion for the first time, according to a new report from a16z. This marks the third consecutive weekly record, with volume more than doubling since the start of the year. Open interest also reached $1.6 billion, reflecting an approximate 8x increase from last fall and signaling much deeper liquidity and stronger market participation.
Structural Shift: From Sports Betting to Macro Forecasting
The composition of trading activity has undergone a significant transformation. Non-sports volume—spanning political elections, economic indicators, and geopolitical events—totaled $3.6 billion in the latest week. This figure already exceeds the entire market's non-sports weekly volume from last year, indicating that prediction markets are no longer dominated by sports betting. Instead, they are rapidly evolving into platforms for forecasting macroeconomic events and policy outcomes. With the U.S. election cycle and interest rate decisions approaching, prediction markets are poised to become critical infrastructure for on-chain data verification and risk hedging for professional traders and institutions.
The data also suggests that prediction markets are attracting a broader user base, including institutional investors who rely on these platforms for real-time sentiment analysis and probabilistic assessments of real-world events. As the market matures, the expansion into political and economic domains could further boost volume and open interest, solidifying prediction markets as a unique asset class in the crypto ecosystem.
