Polymarket US's public fee schedule shows four taker tiers, not the eight it reported to the CFTC
QCX LLC, which trades as Polymarket US, told the CFTC in a weekly notification filed on 10 November (PMX-2026-63) that an amendment to its fee schedule 'took effect on November 6, 2026' and 'is reflected in the public Fee Schedule.' That letter set eight taker-fee tiers, from a coefficient of +0.1170 below $10,000 of notional taker volume to +0.0650 at $50,000,000 and above. The public Fee Schedule, checked on 13 November, instead shows four tiers, with coefficients from 0.095 below $10,000 to 0.0695 at $250,000 or more, and fewer volume thresholds. We have not found a later CFTC filing that adopts the four-tier schedule.
