IEX reorganizes its fee schedule ahead of a confirmed October 2 launch for IEX Options. In a filing published in the Federal Register today, Investors Exchange (SR-IEX-2026-26) restructures its fee schedule to specify that the current schedule applies to equities trading and splits out a new "Additional Fees" schedule shared between equities and options, with incremental tier adjustments, effective immediately. The substance is fee-schedule housekeeping, but it firms up IEX's timeline to become a new listed-options venue. IEX filing, Federal Register
