What it charges
Modeled customer cost on DKeX trades, and what that works out to per contract. All DKeX volume is routed through DraftKings, so the customer fee is DraftKings' all-in fee.
DKeX: fees per day
DKeX: cumulative fees to date
DKeX: effective fee rate per $1 traded
How this is measured
Fees here are computed, not reported. DKeX publishes no fee field. Its filed exchange schedule, effective June 1, 2026, gives the exchange's taker and maker charges, which feed exchange revenue. DraftKings' all-in fee is applied to each print as the customer fee. Both are divided by contracts afterwards. The schedule arithmetic is exact at execution grain; treating the printed side as the customer side is a modeled convention because those records have no aggressor or member identity.
Customer cost and exchange revenue are separate. Customer cost is DraftKings' all-in fee, which already includes the exchange fee. Exchange revenue is the exchange's own taker-plus-maker charge; use the measure toggle on the comparison page to see it. The fee is per side, so a buyer pays it on entry; the fee on a seller's exit is not modeled separately.
Each fee is price-banded and rounded up per execution. The exchange's taker charge is $0.0100 per contract at 3–98¢, $0.0050 at 1¢ and 99¢, and $0.0085 at 2¢. The maker pays $0.0025, or from October 1 on a combination contract round-up(0.035 × C × P × (1 − P)). DraftKings' all-in fee is multiplied by execution quantity and rounded up the same way, so neither is recomputed from daily totals.
None of DraftKings' schedules has a published effective date. Each window is estimated from when a schedule was first seen. The September ladder was first seen on September 2, 2026, and archived on September 24 and 25. The latest text is undated and was supplied on October 16. The September text printed $0.0880 at 97–98¢, a missing-zero typo we modeled as $0.0088. The latest text prints $0.0045 at 97–99¢.
