Kalshi's Non-Sports Fees Surge on 15-Minute Crypto Markets

Kalshi, a prediction market platform, has seen a surge in fee revenue from non-sports contracts, with figures set to exceed $100 million this month. This growth is primarily driven by 15-minute cryptocurrency markets, which have brought in over $20 million in fees over the past seven days. These markets, along with similar 15-minute commodity and finance markets, now account for around 80% of Kalshi’s non-sports fees, surpassing the fees from non-parlay bets on football during the same period.

The non-sports segment has grown significantly faster than sports, making up 19.2% of fee revenue in 2026 compared to just 11% in 2025. In September, non-sports fees constituted more than 25% of fee revenue, with an all-time high of $4.1 million in a single day. The non-sports fee revenue for the year is projected to exceed $700 million, a 24-fold increase from 2025.

Despite the rapid growth, the non-sports fee revenue is heavily concentrated in 15-minute cryptocurrency markets. These markets have grown from generating less than $10,000 per day in January to over $2 million per day in September. Kalshi has expanded into 15-minute markets for commodities and financial indices, further boosting fee revenue. Over the last seven days, 15-minute markets accounted for 20% of fees, despite representing only 13% of volume.

Kalshi representatives argue that these markets facilitate real price discovery, unlike traditional gambling products. Research from financial forecasting platform Synth found that Kalshi’s crypto markets are increasingly predicting subsequent moves in Binance BTC. However, some critics have compared these fast-moving markets to casino-style games, highlighting their similarity to slot machines. The legal status of these contracts has faced few challenges, with only a few states like Minnesota attempting to outlaw them.
