Prediction Markets Hit $25.7 Billion Monthly Volume, Reaching Nearly 5% of Crypto Spot Trading

Summary
$25.7 billion in March 2026 volume pushed prediction markets to nearly 5% of centralized crypto spot exchange trading, up from about 1% six months earlier.
That growth reflects a 10.6% monthly increase from February and a jump from roughly $1.2 billion a year earlier, while crypto spot volumes stayed relatively steady at $1 trillion to $2 trillion-plus.
Polymarket and Kalshi have led the expansion, with sports, politics and crypto contracts driving activity; crypto-specific prediction markets alone handled about $900 million in a March weekly snapshot.
The surge is still concentrated in a small number of popular contracts, leaving many markets thinly traded and raising execution and price-discovery risks for larger traders.
