Volatility Shares' proposed 3x Ethereum futures ETF, ETHK, would need just $362.1 million in assets to reach CME's 8,000-contract accountability level for Ether futures, according to the SEC filing and the sponsor's Oct. 6 disclosed holdings. The SEC approved Cboe BZX's rule change to list ETHK on Oct. 2; the fund's first trading date remains pending.

At ETHU's Oct. 6 disclosed futures valuation of $135,800 of notional per contract, a fund with $362.1 million in assets targeting three times daily exposure would control roughly 8,000 standard CME Ether futures contracts — about $1.0864 billion of notional exposure. Volatility Shares' existing 2x fund, ETHU, already held 19,204 October CME Ether futures contracts worth $2.61 billion as of Oct. 6, against $1.31 billion of net assets as of Oct. 5. That position stands at 2.40 times the accountability level.

What does the 8,000-contract level mean?

CME cut its single-month and all-month Ethereum futures accountability level to an aggregated 8,000 standard contracts effective March 2. An accountability level is a threshold, not a hard cap — participants can hold positions above it, as ETHU does. CME Market Regulation can request information about a position under Rule 560, including positions below the threshold, and can order a participant to stop adding to or reduce a position when needed to maintain an orderly market.

Will CME aggregate the two funds?

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 ETHU and ETHK. If CME treats them as one controlled position, the combined footprint would reach approximately:

• 21,400 contracts at $100 million of ETHK assets
• 27,200 contracts at $362.1 million
• 41,300 contracts at $1 billion

An exemption from aggregation could give ETHK a separate count. The public record leaves that question open.

For context, the CFTC's Sept. 29 futures-only report counted 27,392 open Ethereum cash-settled futures contracts. ETHU's Oct. 6 holdings equal about 70% of that earlier figure, though the dates differ.

How would the fund rebalance daily?

A 3x fund resets its exposure every day, trading roughly six times its starting assets times the benchmark's daily move in a simplified calculation 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, selling after a decline.

ETHK's SEC filing permits later-dated futures, ETH-linked ETPs and ETFs, exchange-traded options, and cash when benchmark futures become unavailable due to accountability levels, position limits, margin requirements, or FCM limits and risk controls.

How does Bitcoin compare?

Volatility Shares' BITX held 6,368 CME Bitcoin futures contracts worth about $2.74 billion as of Oct. 6, against CME's 5,000-contract Bitcoin accountability level. Using BITX's blended disclosed valuation, a 3x Bitcoin fund reaches that level at about $718 million of assets — roughly double ETHK's Ethereum threshold.

If ETHK stays near $100 million in assets, it adds roughly 2,209 contract equivalents. Between $362.1 million and $1 billion, its own position reaches or exceeds 8,000 contracts, and the combined footprint could move far past that if CME aggregates the funds — raising the odds the fund leans on later-dated futures, linked ETPs or options, with wider execution costs or larger tracking error.

ETHK's holdings disclosures once trading begins will show whether front-month Ethereum futures can carry its 3x exposure as assets build, or whether the fallback instruments take over.
