Kalshi Runs 87.6% of Crypto Prediction Market Volume; Sports Category at $33.5B in Q3
Kalshi dominated four of seven prediction market categories by volume in Q3 2026, according to @Bitwise Asset Management data from Allium covering July 1 to September 30, 2026.
In the crypto category, Kalshi held 87.6% market share on $12,401.4 million in total Q3 volume. In sports, Kalshi ran 65.4% of volume on $33,460.0 million, the largest single category in prediction markets by far. Kalshi also led others (93.4% on $6,306.3 million) and business (93.7% on $971.2 million).
Polymarket leads the politics category with 70.4% of $902.0 million in Q3 volume and weather/climate at 52.7% of $274.2 million.
Sports is now the dominant prediction market category by raw volume at $33.5 billion in Q3, dwarfing the combined volume of crypto, politics, and business. That composition matters for understanding where liquidity is actually concentrating in onchain prediction infrastructure.
