NYSE Ditches Limits on Bitcoin ETF Options Trading
Published Date: 8/25/2025
Notice
Summary
NYSE Arca is changing the rules for trading options on the iShares Bitcoin Trust ETF (IBIT). They’re removing the 25,000-contract limit, letting traders hold bigger positions based on recent trading activity. This change kicks in right away and could shake up how much money traders can move in IBIT options.
Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
25,000-Contract Limit Removed
If you trade options on the iShares Bitcoin Trust (IBIT), NYSE Arca removed the 25,000-contract same-side position and exercise limit and will instead apply the position limits set by Rule 6.8-O, Commentary .06. Because IBIT meets the six-month trading thresholds (including the 100,000,000-share six-month volume test), the position and exercise limit for IBIT options may increase to 250,000 same-side contracts.
Exercise Limits Match New Position Limits
The exercise limits for IBIT options will be equivalent to the position limits set under Rule 6.8-O, Commentary .06 (so exercise limits would increase along with position limits). For example, the current exercise limit of 25,000 contracts would be modified to be equivalent to any higher position limit (including the possible 250,000-contract level).
Reporting Rules Stay The Same
Even after increasing IBIT position and exercise limits, the Exchange will keep existing reporting requirements: members must continue to report options positions and hedges to the Exchange, market makers remain exempt from the reporting requirement (though the Exchange may access their position information), and the customer large-position reporting threshold remains at 200 option contracts for the prior day.
Rule Effective Immediately Upon Filing
The Commission waived the 30-day operative delay and designated the proposed rule change as operative upon filing, following the Exchange's filing on August 15, 2025. That means the changed position and exercise limits (and related rules described in this filing) became effective immediately upon filing.
