Nasdaq ISE just updated the rules for trading options on three popular Bitcoin ETFs: Grayscale Bitcoin Mini Trust, Bitwise Bitcoin ETF, and Grayscale Bitcoin Trust. These changes adjust how many options traders can hold and exercise, aiming to keep things fair and smooth. The new rules kicked in right away on August 5, 2025, affecting anyone trading these Bitcoin ETF options and potentially impacting their trading strategies and limits.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
25,000-Contract Cap Removed
If you trade options on the Grayscale Bitcoin Mini Trust (BTC), the Bitwise Bitcoin ETF (BITB), or the Grayscale Bitcoin Trust (GBTC), the Exchange removed the old 25,000-contract position and exercise cap and will instead apply the tiered equity-option limits in ISE Options 9, Section 13 (25,000; 50,000; 75,000; 200,000; or 250,000 contracts, or another number set by the Exchange). This change took effect on August 5, 2025 and means those ETF option classes can qualify for an aggregated limit up to 250,000 same-side contracts where appropriate.
FLEX Options Permitted and Aggregated
If you trade options on BTC, BITB, or GBTC, the Exchange now permits FLEX Options on those ETFs and will aggregate FLEX and non-FLEX positions in the same underlying ETF when calculating position and exercise limits. For example, under a 250,000-contract limit the Exchange said it would restrict a participant from holding positions that could result in the receipt of more than 250,000,000 shares if all options were exercised; this change became effective on August 5, 2025.

2026-17183, Regulation Crypto Assets
The Securities and Exchange Commission ("Commission") is proposing new rules to create a tailored offering regime for certain investment contracts involving crypto assets. The proposed offering regime is intended to facilitate capital formation and accommodate innovation within the crypto asset markets while, at the same time, ensuring that investors are adequately protected and provided with the information they need to make informed investment decisions. The proposed rules would be set forth in a new regulation titled "Regulation Crypto Assets" and would include two exemptions from the registration requirements of section 5 of the Securities Act of 1933. The first exemption would permit offerings of up to $5 million during a four-year period. The second exemption would permit offerings of up to $75 million during each 12-month period. Under both exemptions, issuers would be required to make certain principles-based narrative disclosures available to their investors. In addition, issuers under the second exemption would be required to provide financial statements and would be subject to ongoing reporting requirements. Issuers that rely on these exemptions would remain subject to the antifraud and antimanipulation provisions of the Federal securities laws. The proposed rules also would include a conditional safe harbor from the term "investment contract" in the definitions of "security" in the Securities Act of 1933 and the Securities Exchange Act of 1934. If the conditions of that proposed safe harbor are satisfied, then a crypto asset would be deemed not to be subject to an investment contract for purposes of those definitions of "security."
