IBIT Options Limits Raised Tenfold
MIAX is increasing the position and exercise limits for options on the iShares Bitcoin Trust ETF (IBIT) from 25,000 contracts to 250,000 contracts. The Exchange filed the change on August 5, 2025 and the new limit subjects IBIT to the position-limit parameters in Exchange Rule 307(d), with six-month reviews thereafter.
Reporting and Surveillance Rules Stay in Place
Even with higher IBIT position and exercise limits, MIAX will keep existing reporting requirements: member organizations must continue to report account information and positions as specified, and customer large-position reporting at 200 or more option contracts per class remains. Market-Makers remain exempt from the reporting requirement, though the Exchange may access their position information.
