Kalshi Exchange Fee Structure and Contract Pricing
As a CFTC-regulated designated contract market (DCM), Kalshi structures trading costs across contract execution tiers. Knowing precise contract fees per contract executed—along with ACH and wire withdrawal thresholds—is essential for quantitative traders capturing penny-spread mispricings across prediction venues.
| Transaction Tier | Volume / Frequency | Contract Fee | Settlement Cost |
|---|---|---|---|
| Standard Retail | Under 1,000 contracts/mo | Formula-based cents/contract | Zero settlement deduction |
| Institutional / Pro | 10,000+ contracts/mo | Volume-discounted maker tier | Direct clearing pass-through |
| ACH Deposit/Withdrawal | Standard electronic transfer | Free / $0.00 fee | 1-2 business days |
| Wire Transfer | Same-day domestic wire | Standard wire processing fee | Same-day settlement |
