CFTC-filed fee schedule, per-contract formula: fee = ⌈rate × C × (1 − C)⌉ where C is contract price (0.01–0.99) — same parabolic shape as Polymarket, peaking at 50¢. Maker fee is ~25% of taker fee (charged only on fills, cancels free). Settlement is free.

About

Kalshi is a federally regulated Designated Contract Market (DCM) authorised by the US CFTC. It runs as a centralized limit-order-book exchange with USD bank-rail deposits and KYC. Contracts resolve to $1.00 or $0.00 against an outcome defined in Kalshi's specifications. The company spent years winning regulatory clearance for event contracts and prevailed against the CFTC in court in 2024, opening congressional and election markets to US retail.
