At that asset size, the proposed ETHK would match CME’s accountability limit if it held only standard Ether futures, the report says.
The SEC approved Cboe BZX’s rule change to list Volatility Shares’ proposed ETHK on Oct. 2, and the report says a 3x Ethereum ETF would reach CME’s 8,000-contract accountability level with $362.1 million of assets if it holds standard CME Ether futures. ETHK’s first trading date is pending.
What meets the 8,000-contract line
Using the sponsor’s disclosures, the report derives $135,800 of notional per CME Ether contract from ETHU’s Oct. 6 position. At that value, 8,000 contracts equal $1.0864 billion of exposure. Because a 3x fund targets three times daily performance, it would need about one-third of that in assets, or roughly $362.1 million, to align with CME’s threshold.
The report says Volatility Shares’ existing ETHU held 19,204 October CME Ether futures worth $2.61 billion as of Oct. 6, against $1.31 billion of net assets as of Oct. 5. That position equals about 2.40 times the 8,000-contract level.
CME cut the single-month and all-month accountability level for standard Ether futures to an aggregated 8,000 contracts effective March 2. An accountability level is a threshold: participants can hold positions above it. CME Market Regulation can request information about a position under Rule 560, and the exchange can order a participant to stop adding or to reduce a position when needed to maintain an orderly market, the report notes.
If ETHK holds its full target exposure in standard CME Ether futures, the report estimates contract equivalents of about 2,209 at $100 million of assets, 11,046 at $500 million, and 22,091 at $1 billion, based on ETHU’s Oct. 6 notional per contract. Those counts move with futures prices and portfolio construction.

Aggregation risk and fallback tools
The report explains that CME aggregates positions by ownership or trading control, including accounts where a person controls trading or holds a 10% or greater ownership interest. Volatility Shares manages both funds, so if CME treats them as one controlled position, the combined footprint would reach about 27,200 contracts at $362.1 million of ETHK assets and about 41,300 at $1 billion. An exemption from aggregation could give ETHK a separate count; the public record leaves that answer open, and CME confirmation would clarify it.
Leveraged products reset daily. The report describes a simplified framework in which a 3x fund trades roughly six times its starting assets times the benchmark’s daily move to rebalance, before flows and fees. At $362.1 million of assets, a 5% benchmark move implies about $109 million of rebalancing flow, buying after a rally and selling after a decline.
ETHK’s SEC filing allows later-dated futures, ETH-linked ETPs and ETFs, exchange-traded options, and cash when benchmark futures become unavailable because of accountability levels, exchange position limits, margin requirements, or FCM limits and risk controls. For holders, the report says that route hinges on tracking quality and execution cost, while Ethereum derivative traders focus on the size and timing of futures flows.
Bitcoin comparison
The report says Volatility Shares’ BITX held 6,368 CME Bitcoin futures across October and November worth about $2.74 billion as of Oct. 6, and CME’s Bitcoin accountability level is 5,000 contracts. Using BITX’s blended disclosed valuation, a 3x Bitcoin fund reaches that level at about $718 million of assets, roughly double ETHK’s $362.1 million threshold on Ether.
ETHK’s holdings disclosures once it trades will show whether front-month Ether futures can carry its target exposure as assets build, or whether the filing’s fallback instruments take over.

🧠 HafidWatch Take
CME’s aggregation rules and fallback mechanisms could significantly influence ETHK’s liquidity and risk management as assets grow. If ETHK’s positions are aggregated with Volatility Shares’ other holdings, its effective exposure and accountability levels may be higher than reported, potentially leading to earlier use of fallback instruments that might affect tracking accuracy and execution costs. Monitoring how front-month Ether futures versus fallback products are employed will be crucial for understanding ETHK’s ability to maintain leveraged exposure without undue market impact.
