U.S. Exchanges Scrap Crypto ETF Options Caps, Unlocking Institutional Trading Scale

NYSE Arca and NYSE American scrapped the 25,000-contract position and exercise limits on options tied to 11 spot bitcoin and ether ETFs on Saturday, completing an industry-wide overhaul that began when crypto ETF options first launched just 16 months ago.

The SEC waived its standard 30-day review period, allowing the rule changes to take effect immediately. The agency retains a 60-day window to suspend the rules if further review is warranted, and public comment periods remain open until April 13.

The caps, introduced in November 2024 as a precautionary measure when crypto ETF options debuted, had capped positions at 25,000 contracts per trader. Under the new framework, limits for those products will follow each exchange's standard rules, specifically Exchange Rule 904, Commentary .07, which allows large, liquid ETFs to qualify for limits of 250,000 contracts or more based on trading volume and shares outstanding. The change also removes restrictions that had prevented these products from trading as FLEX options, the customizable contracts institutional traders use to tailor strike prices and expiration dates.

The affected products span the major crypto ETF sponsors: BlackRock's iShares Bitcoin Trust (IBIT), Fidelity's Wise Origin Bitcoin Fund, the ARK 21Shares Bitcoin ETF, Grayscale's Bitcoin Trust ETF and Bitcoin Mini Trust ETF, Grayscale's Ethereum Trust ETF and Ethereum Mini Trust ETF, the Bitwise Bitcoin ETF, the Bitwise Ethereum ETF, the iShares Ethereum Trust ETF, and the Fidelity Ethereum Fund.

NYSE was the final piece of a broader regulatory transition. Nasdaq ISE and Nasdaq PHLX filed to remove the same caps in January 2026, followed by MIAX in January, MEMX in February, and Cboe in March. With NYSE's action, every major U.S. options exchange has now completed the shift. Nasdaq argued in its filing that lifting the limits would allow crypto ETF options to be treated "in the same manner as all other options that qualify for listing," eliminating what it described as unequal treatment without undermining investor protections. The SEC, in reviewing the NYSE proposals, noted they raised no novel regulatory concerns, pointing to identical changes already operative at rival exchanges.

The commercial case for removing the caps was visible from the start. When IBIT options launched under the 25,000-contract constraint, Bloomberg senior ETF analyst Eric Balchunas noted the product generated nearly $1.9 billion in notional exposure on its first trading day. "$1.9b is unheard of for Day One," Balchunas said. "For context, $BITO did $363m and that's been around for four years. And also this is with 25,000 contract position limits. That said, $1.9b isn't quite big dog level yet tho, eg $GLD did $5b today, but give it a few more days/weeks."

The derivative market expansion comes against a backdrop of sustained institutional demand in the underlying spot market. Spot bitcoin ETFs have attracted more than $2 billion in weekly inflows recently, with BlackRock's IBIT accounting for roughly $1.7 billion of that total, even as one week saw a combined outflow of $349 million. Bitcoin has held near $70,000 through the volatility.

One further escalation remains pending. A separate proposal to raise the IBIT-specific options position limit to 1 million contracts is still awaiting SEC approval, a figure that would place BlackRock's bitcoin fund among the most actively traded derivatives vehicles in U.S. markets. Whether the SEC acts on that proposal within the existing 60-day suspension window for the current changes will be the next marker for how far regulators are prepared to normalize crypto as a mainstream asset class.
