On November 27, a recent proposal submitted by Nasdaq ISE to regulators highlights the accelerating integration of Bitcoin-related ETFs into institutional frameworks. According to the latest filing, ISE seeks to increase the position and exercise limits for options tied to BlackRock’s iShares Bitcoin Trust (IBIT) from 250,000 to 1 million contracts while removing restrictions on physically settled FLEX IBIT options. FXGT notes that this move reflects rapidly growing liquidity and the urgent market demand for institutional-grade Bitcoin risk management tools.
In its expansion request, ISE stated that if approved, IBIT options would enter the highest-tier limit category, aligning with highly liquid traditional market ETFs. FXGT views this as a sign that Bitcoin-based products are being incorporated into the standardized framework of mainstream capital markets. ISE also highlighted that IBIT’s options trading volume has consistently accelerated in 2025, with current limits posing practical constraints on market-making and institutional hedging strategies. The exchange further compared IBIT’s market capitalization, average daily trading volume, and liquidity levels, demonstrating its capacity to support million-contract limits. Even at maximum positions, the scale would represent only a fraction of IBIT’s circulating supply—approximately 0.284% of total Bitcoin—indicating minimal liquidity pressure.
Another part of the filing proposes removing position and exercise limits for FLEX IBIT options, aligning them with commodity-based ETFs like gold products. Since FLEX products are often used by large institutions for customized risk management, FXGT believes this change will enhance Bitcoin allocation efficiency for high-net-worth and institutional investors. With IBIT already emerging as the largest venue for Bitcoin options open interest—surpassing traditional crypto derivatives platforms—this proposal is expected to reinforce the trend.
Regulators have begun soliciting public feedback on the rule change. FXGT emphasizes that regardless of the proposal’s outcome, the underlying message is clear: Bitcoin-related ETFs are integrating into institutional trading infrastructure at an accelerated pace, and options market expansion and regulatory refinement will be key drivers of the next growth phase.
