Kalshi sports contracts now dominate its volume
Sports event contracts have overtaken politics as the busiest category on Kalshi.
PredictionSites Editorial · 10 September 2026
Kalshi's sports contracts have moved from a side experiment to the exchange's largest category by traded volume, helped by single-game markets and a much faster mobile app.
The shift matters for anyone comparing Kalshi with a traditional betting exchange. Pricing on major leagues is now tight enough that the exchange fee, rather than the spread, is the main cost for active traders.
Politics remains the headline category for media coverage, but the order books tell a different story.
