Prediction market activity has reached record levels in March, fueled by rising interest in political and geopolitical event contracts, broader platform accessibility, and favorable regulatory momentum. Data tracked by Dune shows transaction counts have surpassed 191 million for the month, representing a 2,838% increase compared to the same point last year. Monthly notional trading volume has climbed to approximately $23.9 billion, up sharply from $1.9 billion at the same time in the prior year, though still about 12% below the all-time high set in January.
Blockchain intelligence firm TRM Labs published a report attributing the sector’s rapid expansion to improved accessibility, regulatory developments, and integration with mainstream platforms such as Google Finance. The firm noted that prediction markets are increasingly being used as real-time indicators of geopolitical and macroeconomic events. Mainstream media coverage of live odds has also contributed to growing public awareness of the space.
Prediction markets allow users to trade contracts tied to the outcomes of future events, and they are emerging as a notable real-world application for blockchain technology. Some platforms rely on crypto infrastructure and stablecoins for settlement and payments. TRM Labs observed that crypto-native topics have receded in prominence as users shift toward contracts linked to political and global developments.
According to TRM Labs, geopolitical events, US politics, and macroeconomic decisions now account for the majority of trading volume, while crypto-native subjects represent a shrinking share of overall activity. Data from Polymarket shows that the five highest-volume contracts as of Monday revolve around which candidates the major US political parties will nominate for the 2028 presidential race and whether Israeli Prime Minister Benjamin Netanyahu will remain in office by year-end. This shift reflects a broader trend of prediction markets being used to price real-world political risk.
The sector has not been without controversy, facing scrutiny over allegations of insider trading and potential violations of gambling laws. In March, both Kalshi and Polymarket announced plans to introduce trading guardrails on the same day US lawmakers unveiled a bipartisan bill aimed at banning event contracts that resemble casino-style gambling. A Nevada judge also temporarily blocked Kalshi from operating within the state, underscoring the regulatory pressures facing the industry.
Looking ahead, TRM Labs cautioned that the continued growth of prediction markets will depend on how the industry addresses key challenges, including market integrity and susceptibility to manipulation. The firm suggested that prediction markets have the potential to evolve beyond speculative platforms into core infrastructure for real-time information aggregation and risk pricing. How regulators and platform operators respond to current concerns is expected to play a significant role in shaping that trajectory.
