As of May 2026: Market leader implementing fee increases across subsidiary exchanges

Options exchanges are locked in a chaotic race to recalibrate fees as their regulatory costs collide with record trading volumes. Cboe doubled its Options Regulatory Fee to $0.0002 per contract on January 2, 2026, while NYSE slashed its fee from $0.0038 to $0.0026.
