The U.S. Securities and Exchange Commission has opened a public comment period on a Cboe 3x Bitcoin and Ethereum ETF proposal, moving the leveraged product filing into a formal feedback stage rather than toward any immediate approval or denial.
What the SEC Comment Period Means for Cboe’s ETF Proposal
The filing was submitted by Cboe BZX Exchange and is documented in the SEC’s self-regulatory organization rulemaking record under the SR-CboeBZX-2026-065 designation. It concerns a proposed rule change tied to leveraged exchange-traded funds referencing Bitcoin and Ethereum.

A public comment period is a procedural step in which the SEC invites investors, market participants, and other interested parties to submit written views on a proposed rule change. Opening comments is not an endorsement, and it does not mean the products have cleared review. For related coverage, see Best Bitcoin Lightning Wallet for Merchants.
The full text of the proposal is set out in the exchange’s filing published on SEC.gov. The comment stage precedes any order to approve, disapprove, or institute further proceedings. This is a familiar path for digital asset products, following the same public comment mechanism the SEC uses for broader ETF rule questions.
How the 3x Bitcoin and Ethereum ETFs Would Work
A 3x leveraged ETF is designed to deliver three times the daily percentage move of its reference asset. When Bitcoin rises one percent on a given day, such a fund targets a three percent gain, and losses are magnified by the same multiple.
The Cboe proposal covers exposure to both Bitcoin and Ethereum, the two largest assets by market value. Ethereum is the settlement layer for a large share of decentralized finance activity, a category of on-chain lending and trading applications that operates without traditional intermediaries.
Leverage compounds daily, so returns over longer holding periods can diverge sharply from a simple 3x of the underlying’s move. That decay characteristic is why leveraged funds are generally framed as short-duration tools, and it is central to the investor-protection questions such products raise for retail holders.
Why This Filing Matters for the Broader Digital Asset ETF Market
A dual Bitcoin and Ethereum leveraged filing signals that issuers are testing demand for structures beyond plain spot funds. The rule filings that Cboe BZX submits are tracked publicly through the exchange’s BZX rule filings page.
How the SEC treats higher-risk ETF structures can shape expectations for similar applications, since market participants read each procedural step for signals about the regulator’s posture toward complex crypto products. That interpretive weight sits alongside the agency’s wider work on a crypto regulatory framework as the CLARITY Act advances.
The distinction matters for Bitcoin specifically. A leveraged wrapper is a derivative of price, not of the network, and it does not alter Bitcoin’s fixed issuance schedule, its proof-of-work security model, or the base-layer settlement that continues independent of how exposure is packaged on regulated venues. That separation between financial products and monetary properties is a recurring theme in how U.S. proposals draw lines around issuers rather than the underlying protocol.
The comment window now sets the near-term timeline, with the SEC required to act within the statutory review periods that follow publication before the proposal can advance.
