What it charges
OG/Crypto.com's standard direct-member exchange-fee benchmark, and what that works out to per dollar of contract.
Fees per day
Cumulative
Effective rate
How this is measured
Reported fees divided by reported contracts, on days carrying both. Days without a defensible numerator are absent, not drawn as zero.
Why a fee rate moves at all. Most of these venues charge a parabola in price — roughly Θ × contracts × p × (1−p) — which peaks at 50¢ and falls to nearly nothing in the tails. So an effective rate tracks where on the probability axis the venue traded, not a change in its published schedule.
Restated per $1 of contract. OG/Crypto.com redenominated twice ($100 → $10 → $1) and the source counts one of each as a single contract, so the raw ratio would draw the first 141 days at 100¢ against Kalshi's 0.84¢ — a 119× cost gap that never existed, since $1.00 on a $100 contract is the same ~1%.
This is not Crypto.com's current app fee. The app moved on June 30, 2026 to a published 1–1.75¢ taker range, with maker and settlement fees at zero. The daily bulletin has no execution prices or member roles, so it cannot identify which retail rate applied; the comparison page draws both published bounds rather than fabricating a daily point.
