Methodology

Overview

Kalshi fee revenue is computed from actual trade executions retrieved via the Dome API. Each trade record includes the number of contracts, execution price, and taker side.

Fee Formula

Each trade contributes fee revenue from both sides:

Taker Fee = 0.07 × contracts × P × (1 − P)

Maker Fee = 0.0175 × contracts × P × (1 − P)

where P is the trade's yes-side execution price. Kalshi charges a 7% taker fee and a 1.75% maker fee on each trade. Fees are aggregated into 1-minute buckets.

Scope & Limitations

Both taker fees (7%) and maker fees (1.75%) are computed for each trade.
The fee formula uses raw (un-ceiled) values rather than applying the per-contract ceiling, which slightly understates actual per-contract fees but is more accurate in aggregate.
Only the two Super Bowl moneyline markets (Seattle, New England) are included. Prop bets, player markets, and other related Kalshi contracts are not captured.
Trade data covers the game-day window (Feb 8 22:00 UTC through Feb 9 04:00 UTC).
