In brief

  • SEC approved Cboe BZX's rule change to list Volatility Shares' ETHK on Oct. 2.
  • ETHK would reach 8,000 CME contracts at $362.1 million in assets, per CryptoSlate.
  • ETHU, the sister fund, already holds 19,204 contracts, 2.40 times CME's level.
  • CME aggregation of the two funds' positions isn't clear from the public record.

How the $362 million figure works

CryptoSlate built its math on ETHU, Volatility Shares' existing leveraged Ether fund. Fund disclosures cited by the outlet show ETHU 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.

Those holdings imply $135,800 of notional value per contract (which puts 8,000 contracts at $1.0864 billion). At that valuation, CryptoSlate calculated that a 3x fund with $362.1 million would target about $1.09 billion of exposure. If all of it sat in standard CME Ether futures, that's 8,000 contracts.

That number matters because CME cut its Ethereum accountability level to an aggregated 8,000 standard contracts, effective March 2.

ETHU is already at 2.40 times that level.

A threshold, not a cap

CryptoSlate was careful on this point:

An accountability level is a threshold, and participants can hold positions above it, as ETHU does.

CME Market Regulation can still request information under Rule 560 (even below 8,000 contracts), and it can order a participant to stop adding to a position or reduce it when needed to maintain an orderly market.

So what about aggregation? CME aggregates positions by ownership or trading control, and Volatility Shares manages both funds. If CME treats them as one controlled position, CryptoSlate estimated the combined footprint would reach about 27,200 contracts at $362.1 million of ETHK assets and 41,300 at $1 billion. An exemption could give ETHK a separate count. The outlet said the public record doesn't show whether one would apply.

Market footprint and fallbacks

The CFTC's Sept. 29 futures-only report counted 27,392 open Ethereum cash-settled futures contracts, and ETHU's Oct. 6 holdings equaled about 70% of that (the dates differ). At $362.1 million, CryptoSlate estimated a 5% benchmark move implies about $109 million of rebalancing flow, buying after rallies and selling after declines.

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, position limits, margin requirements or FCM limits.

Bitcoin has more headroom. CME's Bitcoin level is 5,000 contracts, and CryptoSlate estimated a 3x Bitcoin fund would get there at about $718 million, roughly double ETHK's threshold.

Frequently asked questions

What is CME's accountability level for Ether futures?

CME lowered its single-month and all-month Ethereum futures accountability level to an aggregated 8,000 standard contracts, effective March 2. According to CryptoSlate, it's a threshold rather than a cap, and participants such as ETHU can hold positions above it.

Can CME act on a position below 8,000 contracts?

Yes. Under Rule 560, CME Market Regulation can request information about a position, including one below the 8,000-contract level. CME's rules also let it order a participant to stop adding to a position or to reduce it when needed to maintain an orderly market.

What can ETHK hold if CME futures aren't available?

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, position limits, margin requirements or FCM limits.
