Crypto ETF options are rapidly being folded into mainstream derivatives markets as U.S. exchanges abandon fixed caps, unlocking larger positions and reshaping how institutional capital can access bitcoin and ethereum exposure.
NYSE American Expands Crypto ETF Options With Flexible Limit Framework
The U.S. Securities and Exchange Commission (SEC) published a on March 18, 2026, of the filing and immediate effectiveness of a proposed rule change by NYSE American LLC regarding options on certain crypto assets. The development places the exchange as the most recent participant in a broader shift by major U.S. options venues to recalibrate limits and trading flexibility for crypto ETF derivatives.
Included in the scope are Grayscale Bitcoin Trust (GBTC), Grayscale Bitcoin Mini Trust ( BTC), Bitwise Bitcoin ETF (BITB), Blackrock’s Ishares Bitcoin Trust (IBIT), Fidelity Wise Origin Bitcoin Fund (FBTC), ARK 21Shares Bitcoin ETF (ARKB), Grayscale Ethereum Trust ETF (ETHE), Grayscale Ethereum Mini Trust ETF ( ETH), Bitwise Ethereum ETF (ETHW), Ishares Ethereum Trust ETF (ETHA), and Fidelity Ethereum Fund (FETH). The SEC stated:
“The Commission is publishing this notice to solicit comments on the proposed rule change from interested persons.”
Rather than keeping a uniform cap, NYSE American restructures exposure limits by placing these options under its tier-based framework tied to liquidity. The change eliminates the 25,000-contract restriction and removes aggregation between FLEX and non-FLEX positions. FLEX options, which allow market participants to customize key contract terms such as strike price, expiration date, and exercise style, would be available across all qualifying crypto ETFs without prior limitations.
Nasdaq and Cboe Align With Liquidity-Based Model for Crypto Derivatives
Earlier in 2026, Nasdaq similar revisions across its options platforms, replacing fixed caps with scalable limits and expanding FLEX availability. IBIT became a central focus in those filings, with efforts to raise its allowable exposure beyond 25,000 contracts as activity increased, placing it on a trajectory toward the highest tier of limits, which can reach up to 1,000,000 contracts for the most actively traded products.
Cboe followed with comparable updates in February, integrating crypto ETF options into its broader commodity-based trust framework. The exchange removed product-specific constraints, permitted broader use of FLEX options, and aligned position and exercise limits with liquidity-based thresholds rather than fixed ceilings.
Common eligibility standards underpin these changes, requiring that underlying assets maintain at least a $700 million average daily global market value over a 12-month period and trade in derivatives markets subject to surveillance-sharing agreements. Products meeting these benchmarks qualify for the expanded limit structure now applied across exchanges.
Finally, each filing took effect immediately, allowing the updated rules to be implemented without delay while leaving room for the SEC to suspend them within 60 days if necessary to protect investors or preserve orderly markets.
