Everybody's Gotta Have an Opinion: Prediction Markets Log 192M Transactions in March

Prediction markets casually shrugged off skeptics and logged 192 million transactions in March 2026—because apparently, everyone wants to bet on what happens next. Volume and user growth kept their relentless moon mission going, year over year, no signs of stopping.

The monthly user count hit a smug new high of 865,411, roughly 118% more than the 396,642 users grinding away in March 2025. Monthly notional trading volume stumbled into approximately $23.89 billion, a face-melting 1,107% increase year over year. For the spreadsheet obsessives keeping score: that's still about 10.7% below January's all-time high of $26.7 billion. Close, but no cigar.

BeInCrypto's analysis found that sports, crypto, and politics form the holy trinity of weekly volume on Polymarket. Meanwhile, over on Kalshi, the exotics category snuck past politics in late February to elbow its way into the top three categories by weekly volume. Turns out people really want to know if it'll snow on Christmas before they actually bet on it.

User behavior tells a fascinating tale of democracy in action. On Polymarket, over 57% of users throw around less than $100 per position—picnic money in crypto terms. The average active participant executes roughly 25 trades per day, a frequency that whispers "retail stock trader energy" rather than "traditional betting grandpa."

Of course, no crypto success story arrives without its villain arc. Prediction markets are catching the regulatory stink eye. Lawmakers introduced multiple bills in March alone, ranging from curbing insider trading to banning war-related contracts.
