SEC notice detailed Nasdaq ISE’s move to ease crypto ETF options restrictions

On January 21, 2026, the U.S. Securities and Exchange Commission issued Release No. 34-104648, recording a Nasdaq ISE rule filing designed to remove special restrictions from options tied to a group of spot bitcoin and ether exchange-traded products. The filing was a market-structure change, not an SEC approval of bitcoin, ether, the funds or options as investments.

Nasdaq ISE had submitted SR-ISE-2026-01 on January 7, 2026. The exchange proposed treating the covered crypto-fund options more like other eligible options under its rules: removing specified 25,000-contract position and exercise limits, permitting additional products to trade as FLEX options, and deleting special aggregation language for certain FLEX and non-FLEX positions.

What the filing changed

The filing covered 12 exchange-traded products. Seven held bitcoin: the iShares Bitcoin Trust ETF, Grayscale Bitcoin Trust, Grayscale Bitcoin Mini Trust BTC, Bitwise Bitcoin ETF, Fidelity Wise Origin Bitcoin Fund, ARK 21Shares Bitcoin ETF and VanEck Bitcoin ETF. Five held ether: the iShares Ethereum Trust ETF, Fidelity Ethereum Fund, Bitwise Ethereum ETF, Grayscale Ethereum Trust and Grayscale Ethereum Mini Trust.

The treatment was not identical for every product because some restrictions had already been relaxed in 2025. For Fidelity, ARK and VanEck bitcoin-fund options and the five ether-fund options, ISE proposed deleting the explicit 25,000-contract position and exercise limits and applying its generally applicable rules. It also proposed allowing those eight products to trade as FLEX options, whose terms can be customized within exchange rules.

For the iShares Bitcoin Trust ETF, Grayscale Bitcoin Trust, Grayscale Bitcoin Mini Trust BTC and Bitwise Bitcoin ETF, earlier actions had already addressed the 25,000-contract cap and FLEX trading. The January filing instead removed special language that aggregated certain FLEX positions with non-FLEX positions. The exchange said the combined edits would place qualifying crypto-asset fund options on treatment similar to other options for position limits, exercise limits and FLEX trading.

Why it mattered

Options give institutions and other market participants tools to hedge, express volatility views and structure exposure without transacting directly in the underlying cryptocurrency. FLEX options add negotiated features such as exercise style, strike or expiration within the exchange framework. Removing product-specific restrictions could therefore expand the range and scale of regulated hedging around spot crypto funds.

The institutional significance was normalization, not immediate proof of deeper liquidity. ISE argued that consistent treatment promoted equitable trading and expected other options exchanges to adopt substantively similar proposals. That was the exchange’s stated rationale, not an independently measured result. The filing supplied no event-day evidence that spreads tightened, volume increased or investor outcomes improved, so this reconstruction makes no such claim.

Status and limits on January 21

The rule change became effective under the self-regulatory-organization filing process, but the filing said it would not become operative for 30 days after January 7 unless the SEC designated a shorter period. The SEC also retained authority to temporarily suspend it within 60 days of filing and institute proceedings. “Immediate effectiveness” therefore did not mean every operational change was available on January 21.

The SEC’s dated notice established the January 21 regulatory record; the Federal Register publication followed on January 26, 2026, with comments due February 17, 2026. That later publication clarifies procedure but does not change what the filing proposed. The next factual checks are the operative date, any SEC suspension, parallel exchange filings and actual post-implementation trading data.
