Bitcoin ETF Traders Can Now Hold Bigger Options Positions
Published Date: 6/15/2026
Notice
Summary
MEMX is raising the limits on how many options traders can hold and exercise for the iShares Bitcoin Trust ETF (IBIT). This change affects anyone trading IBIT options and lets them handle bigger positions starting right away. It’s designed to keep MEMX competitive and support growing market interest without any immediate cost impact.
Analyzed Economic Effects
3 provisions identified: 3 benefits, 0 costs, 0 mixed.
Aims to Support Liquidity and Keep Trading On-Exchange
MEMX says the higher IBIT options limits should help market makers and liquidity providers offer more liquidity and discourage moving trading to over-the-counter (OTC) markets. That intends to keep more price discovery and reported trades on public exchanges rather than in less transparent OTC deals.
IBIT Options Limits Raised to 1,000,000
If you trade options on the iShares Bitcoin Trust (IBIT), MEMX raised the position and exercise limits from 250,000 contracts to 1,000,000 contracts for the same side of the market. This change explicitly permits you to hold and exercise larger IBIT options positions (up to 1,000,000 contracts).
Change Effective Immediately Upon Filing
The Commission waived the normal 30-day delay, so the new 1,000,000-contract IBIT options limits became operative upon filing (filed May 27, 2026). That means you could use the higher limits right away after filing rather than waiting 30 days.
