Cboe May List ETH ETF Options
On April 9, 2025, Cboe filed a rule change that allows the Exchange to list and trade options on the iShares Ethereum Trust (the Trust). If you invest in or trade options, this gives you a new, exchange-listed way to gain exposure to the price of ether through the Trust.
Listed Options Move Activity From OTC
The filing says investors who traded options on ether in the unregulated OTC market may prefer the listed option market because listed options give exchange trading, OCC clearing, OPRA reporting, and more market transparency. That could make it easier and safer to open and close ether-related option positions on an exchange.
25,000-Contract Position and Exercise Limits
The Exchange proposes a same-side position limit and equivalent exercise limit of 25,000 option contracts for options on the iShares Ethereum Trust. The filing explains the 25,000 limit and compares it to the Trust's market capitalization and average daily volume to support that level.
Trust Excluded From FLEX Options
The Exchange amends Rule 4.20 to exclude the iShares Ethereum Trust from the provision that would permit FLEX option classes on an equity security. That means FLEX-style customizable options will not be authorized for this Trust.
Settlement, Strikes, and Minimum Increments Set
Options on the Trust will be physically settled with American-style exercise. Strike intervals will be $1 (when strike ≤ $200) and $5 (when strike > $200). Where an option price is under $3.00 the minimum increment will be $0.05, and at $3.00 or higher the minimum increment will be $0.10 (with penny-interval program alternatives noted in the filing).

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."
