Prediction markets saw a dramatic surge in activity in March, driven by growing interest in political and geopolitical event contracts, wider accessibility, and favorable regulatory developments.
According to Dune-tracked data, transactions exceeded 191 million through March so far — a 2,838% increase versus the same period last year. Blockchain intelligence firm TRM Labs said mainstream coverage, including Google Finance listing live odds, has amplified public awareness and participation. “Prediction markets have scaled rapidly due to improved accessibility, regulatory developments, and integration with mainstream platforms,” TRM Labs noted, adding that these markets are increasingly used as real-time indicators of geopolitical and macroeconomic events.
Users trade contracts that pay out based on the outcomes of future events; many platforms settle in crypto rails and stablecoins, making them a growing real-world use case for blockchain. Monthly notional trading volume reached roughly $23.9 billion in March so far, up sharply from about $1.9 billion at the same point last year, per Dune — though that figure remains roughly 12% below January’s all-time monthly peak.
TRM Labs also observed a thematic shift: crypto-native topics have lost share as traders concentrate on geopolitical flashpoints, U.S. politics and macroeconomic decisions. Polymarket analytics show the five highest-volume contracts currently center on which major U.S. parties will nominate candidates for the 2028 presidential race and whether Israeli Prime Minister Benjamin Netanyahu will remain in office by year-end.
The sector has attracted increased scrutiny amid allegations of insider trading and concerns about gambling-law violations. In response to those risks and public attention, platforms such as Kalshi and Polymarket announced plans in March to introduce trading guardrails. The same month, U.S. lawmakers unveiled a bipartisan bill aimed at banning event contracts that resemble “casino-style” games.
TRM Labs cautioned that future growth will depend on how platforms manage market integrity and manipulation risks. The firm suggested that, with deeper liquidity and broader participation, prediction markets could evolve from speculative venues into core infrastructure for real-time information aggregation and risk pricing — potentially complementing or competing with traditional forecasting tools.
