Prediction markets recorded $188 billion in volume in Q3 2026, nearly 70% above Q2 and 21 times the level in Q3 2025. Kalshi was the main driver of the growth, with sports accounting for around 40% of its Q3 trading volume.
Why it matters
The record marks a sharp expansion in prediction-market activity over both the previous quarter and the prior year. Kalshi’s contribution places the platform at the center of the reported growth, while the sports share highlights one major source of its trading activity.
Market impact
The figures point to rising activity across prediction markets, but the report does not break out volume by platform beyond identifying Kalshi as the main driver. The share of sports trading also applies to Kalshi, not the entire sector.
