560,341 combo prints, 112,039,223 contracts, $14,584,822 notional. The fee schedule is silent on whether a combo is one execution or n_legs, so this is a band. HIGH is understated for 20,045 prints on combos that have not settled (leg count unknown; counted as one). Fees are flat per contract within a price band, so cheap combos pay a far larger share of their own premium. Combo revenue is not included in any figure above this section.

External benchmark check

A July 2026 press report cited $11,300,000,000 of weekly volume. For the week of Jun 29, 2026 the exchange's own files show 805,150 contracts and $388,580 of premium notional (max-payout notional $805,150) — three to four orders of magnitude below the reported figure. Lifetime single-leg premium notional across the entire archive is $84,984,916. Either the report used a measure not derivable from public data, or the figure is wrong. Shown for calibration, not endorsement.
