The U.S. Securities and Exchange Commission has opened a public comment period on Cboe BZX’s proposal to list and trade a 3x Bitcoin ETF and a 3x Ether ETF, formally launching the regulatory review clock on one of the most aggressively leveraged crypto products yet to reach the SEC’s desk, with feedback due Sept. 9, 2026.
The comment window stems from filing SR-CboeBZX-2026-065, which the SEC issued as Release No. 34-106137 with an SEC issue date of Aug. 14, 2026, according to the Commission’s rulemaking notice. Opening comments does not signal endorsement; it is a procedural step under the SEC’s self-regulatory-organization framework that invites public input before the agency decides how to proceed.
The notice reached the Federal Register on Aug. 19, 2026 as document 2026-16854, carrying citation 91 FR 53686. That publication date matters because the SEC’s statutory review timeline runs from the Federal Register date, not the earlier internal issue date.
What a 3x Bitcoin and Ethereum ETF Would Actually Track
The proposed 3x Bitcoin ETF seeks three times the daily performance of bitcoin, achieved through first- and second-month CME bitcoin futures rather than physically held bitcoin, per the Cboe filing. The 3x Ether ETF mirrors that design, targeting three times ether’s daily move via first- and second-month CME ether futures instead of spot ether.
Triple leverage means a fund engineered to return roughly three times an asset’s daily percentage change, resetting each session, so a 5% single-day bitcoin gain targets a 15% fund move. That daily reset also compounds against holders in choppy or declining markets, amplifying losses as sharply as gains, a structural risk that distinguishes these products from the spot funds now common in the market.
Combining leveraged bitcoin and ether exposure in a single filing is notable because these would rank among the first U.S. 3x single-crypto ETFs, escalating well beyond the 2x leveraged crypto funds already trading, and beyond the reinvesting-dividend structures firms like Franklin Templeton have pursued for bitcoin exposure.
Why the Comment Period Does Not Equal Approval
The filing sits at the notice-of-filing stage, meaning the SEC has acknowledged Cboe’s submission and solicited feedback but has taken no position on the merits. Within 45 days of Federal Register publication, extendable to as many as 90 days, the Commission must approve, disapprove, or institute proceedings on the proposal, according to the issued notice.
Comment periods let issuers, market participants, and the public weigh in on structure, investor protection, and market-manipulation concerns, and that feedback can shape whether the SEC extends review or moves to formal proceedings. For crypto ETF watchers tracking the pipeline from spot products toward derivatives-based and leveraged formats, the Sept. 9 deadline is the first concrete milestone; approval, if it comes, would land later.
How Cboe’s Filing Fits the Leveraged Crypto ETF Conversation
Cboe’s SR-CboeBZX-2026-065 covers six VS Trust products in total, including the 3x Bitcoin ETF and 3x Ether ETF, positioning the exchange as the listing venue driving the leveraged-crypto push. Cboe filed the proposal on Aug. 10, 2026, ahead of the SEC’s Aug. 14 release, establishing a compressed timeline from exchange submission to public comment.
Unlike standard spot-style crypto ETFs that can qualify under generic listing rules, these leveraged funds required a special proposed rule change. Cboe states the funds do not satisfy BZX Rule 14.11(e)(4)(F) because that generic listing standard prohibits leveraged products, forcing case-by-case SEC review rather than automatic qualification.
That rule-specific hurdle is precisely why regulators scrutinize structure and investor risk here: leveraged commodity-trust products fall outside the pre-approved framework, so the SEC must weigh the futures-based design and daily-reset mechanics before any listing. The distinction underscores why this filing carries more regulatory friction than the spot bitcoin and ether ETFs that cleared earlier review cycles.
Where Bitcoin Sits as the Review Opens
Bitcoin traded at roughly $78,619 as the comment period opened, up about 7.4% over 24 hours, with a market capitalization near $1.58 trillion and 24-hour volume around $71.8 billion, per CoinGecko market data referenced in the research snapshot. The crypto Fear and Greed Index sat at 72, in “Greed” territory, signaling a risk-on backdrop as the leveraged-product debate advances.
Industry reaction skewed constructive rather than skeptical. ETF analyst Nate Geraci flagged the SEC’s acknowledgement of the 19b-4 filing and grouped it with parallel 3x leveraged commodity ETF efforts spanning gold, silver, oil, and natural gas.

The next concrete trigger is the Sept. 9, 2026 comment close, after which the SEC’s 45-day statutory window, extendable to 90 days, governs whether the agency approves, rejects, or opens formal proceedings on the leveraged funds. Institutional desks watching the broader crypto ETF pipeline, including recent regulatory shifts abroad such as Vietnam’s licensing pilot for crypto exchanges, will read the SEC’s handling of this filing as a signal on how far U.S. regulators are willing to extend the product frontier.
FAQ: The SEC Review of Cboe’s 3x Bitcoin and Ethereum ETF
What is an SEC comment period? It is a formal window during which the public, issuers, and market participants can submit written feedback on a proposed rule change before the SEC decides whether to approve, disapprove, or extend review. For this filing, comments are due Sept. 9, 2026.
Does opening a comment period mean approval is likely? No. It is a procedural step signaling active consideration, not endorsement. The SEC must still act within 45 days of Federal Register publication, extendable to 90 days.
What does 3x mean in a Bitcoin and Ethereum ETF? It means the fund targets three times the daily percentage move of bitcoin or ether, here through CME futures rather than physical crypto, which amplifies both gains and losses and resets exposure daily.
Why is Cboe involved? Cboe BZX is the exchange seeking to list the funds and filed SR-CboeBZX-2026-065 with the SEC, using a special rule change because BZX Rule 14.11(e)(4)(F) bars leveraged products from generic listing standards.
