SEC caps leveraged funds at 200%. Cboe just filed for 300%.

What Did Cboe Actually File For With the SEC?

For six years, the ceiling on U.S. leveraged funds has been 200%. A filing submitted on August 10 asks the SEC to let a crypto product go past it — using a wrapper the 200% rule does not reach.

Cboe BZX Exchange filed proposed rule change SR-CboeBZX-2026-065 with the SEC on August 10, 2026, asking for permission to list and trade six triple-leveraged (3x) exchange-traded products, two of which track bitcoin and ether . The SEC published the filing for public comment on August 14, 2026 under Release No. 34-106137 . If approved and launched, the bitcoin and ether sleeves would be the first products offering 3x daily crypto exposure on a U.S. national securities exchange.

Quick Answer: Cboe BZX filed SR-CboeBZX-2026-065 on August 10, 2026, seeking to list six 3x leveraged funds from Volatility Shares — including 3x Bitcoin and 3x Ether. They are structured as CFTC commodity pools, not 1940 Act funds, placing them outside SEC Rule 18f-4's 200% leverage cap .

The proposal is not crypto-only. All six funds are sponsored by Volatility Shares LLC and organized as separate series of VS Trust :

• 3x Gold ETF — 3x daily COMEX gold futures exposure
• 3x Silver ETF — 3x daily COMEX silver futures exposure
• 3x Bitcoin ETF — 3x daily CME bitcoin futures exposure
• 3x Ether ETF — 3x daily CME ether futures exposure
• 3x Crude Oil ETF — 3x daily NYMEX crude futures exposure
• 3x Natural Gas ETF — 3x daily NYMEX natural gas futures exposure

The crypto novelty is narrower than headlines suggest. Cboe's own filing notes that roughly 67 U.S.-listed exchange-traded products already target +3x or -3x performance — 51 Investment Company Act ETFs and 16 Securities Act ETNs . What is untested is 3x crypto-linked exposure inside a commodity-pool wrapper listed on a national exchange.

One point deserves emphasis before anyone starts watching for a ticker: this is a listing-rule filing, not a trading approval. The filing states plainly that the trust's registration statement is not yet effective and that shares will not trade until it is . Two separate gates must clear — SEC action on the 19b-4 listing standard, and S-1/registration effectiveness. As of today, no listing date, no tickers, and no expense ratios have been announced .

Why the SEC's 200% Leverage Cap Doesn't Block This Filing

The 200% ceiling that keeps every existing U.S. leveraged crypto ETF at 2x comes from SEC Rule 18f-4, adopted in 2020, which governs derivatives use by registered investment companies — funds registered under the Investment Company Act of 1940 . Cboe's proposed funds would not be registered investment companies at all. VS Trust and each of its six series would be CFTC-registered commodity pools, a wrapper that sits outside Rule 18f-4's jurisdiction entirely . That structural choice is not incidental — it is the mechanism that makes a 300% daily target arguable in the first place.

The distinction matters because two different federal statutes are in play. A 1940 Act fund answers to the SEC's derivatives rulebook, where value-at-risk limits translate into a hard 200% leverage ceiling. A commodity pool answers to the Commodity Futures Trading Commission and the National Futures Association, which impose registration, disclosure, and reporting duties on pool operators but do not carry an equivalent numeric leverage cap. Volatility Shares LLC would serve as sponsor and CFTC-registered commodity pool operator for all six series . The same issuer already runs BITX and ETHU, its 2x bitcoin and ether products on Cboe BZX, which stop at double exposure precisely because of where they sit in that regulatory map .

Cboe does not present the commodity-pool route as a loophole. According to The Block, the filing frames the structure as supplying "an additional layer of federal regulatory oversight — beyond what a physical commodity-based exchange-traded product would be subject to" .

"An additional layer of federal regulatory oversight — beyond what a physical commodity-based exchange-traded product would be subject to." — Cboe BZX Exchange, SR-CboeBZX-2026-065 (source: Cboe filing PDF)

The reasoning runs like this: a spot bitcoin trust holds an asset with no federal market regulator sitting above it, whereas a commodity pool holding CME futures is supervised by the CFTC on the derivatives side and by the SEC on the listing side. Whether the SEC accepts that framing is the open question the comment period exists to answer.

The service-provider roster reinforces the point that this is a conventional institutional structure, not an offshore workaround. U.S. Bancorp Fund Services would act as transfer agent, fund accountant, and administrator; U.S. Bank National Association as custodian; and Wilmington Trust, National Association as trustee . These are the same names that appear across mainstream U.S. fund paperwork.

For traders, the practical read-through is narrower than the headline suggests. The 200% cap is not being repealed, challenged, or reinterpreted — 1940 Act funds will still stop at 2x whatever happens here. What is being tested is whether a parallel wrapper can carry a higher multiple onto a U.S. national securities exchange. If the SEC blesses it, the ceiling on U.S.-listed crypto leverage effectively becomes a question of fund structure rather than a fixed number. If the SEC rejects it, the 2x products already trading remain the practical maximum for onshore leveraged crypto exposure.

Why Cboe Needed a Special 19(b) Filing Instead of the Fast-Track Path

Cboe filed individually because its own generic listing standards forbid exactly what these funds do. BZX Rule 14.11(e)(4)(F) prohibits leveraged Commodity-Based Trust Shares, and Cboe states in SR-CboeBZX-2026-065 that the six proposed funds fail that standard because each seeks 3x daily benchmark returns . That disqualification is what forces the slower Section 19(b) route: an individual rule change the SEC must publish, take comment on, and formally act upon.

The fast-track path exists and works well — for everything else. In September 2025 the SEC approved generic listing standards for Commodity-Based Trust Shares, letting qualifying products list without a bespoke rule filing for each one . That framework is why the pipeline of single-asset spot commodity and digital-asset products has moved so quickly over the past year. A 3x daily-reset product simply cannot enter through that door, so Cboe had to knock on the other one.

What makes the sequencing informative is how recently Cboe touched the same rule. On August 3, 2026 — one week before the 3x filing — the SEC granted accelerated approval to SR-CboeBZX-2026-061, which amended Rule 14.11(e)(4) to permit a 15% NAV buffer of non-qualifying assets, add a definition of "digital commodity," and allow actively managed strategies . Cboe widened the generic standard first, then filed separately for the one attribute the standard still refuses to accommodate.

Read together, the two filings look less like an opportunistic swing and more like staged construction of a regulatory runway:

• September 2025: generic listing standards approved, removing per-product 19b-4 friction for qualifying commodity ETPs .
• August 3, 2026: SR-CboeBZX-2026-061 approved on an accelerated basis, adding the 15% buffer, the "digital commodity" definition, and active-management latitude .
• August 10, 2026: SR-CboeBZX-2026-065 submitted, seeking an exception to the leverage prohibition for six Volatility Shares funds .
• August 14, 2026: the SEC published the filing for public comment under Release No. 34-106137, starting the statutory clock .

For traders, the practical takeaway is procedural rather than directional. A 19(b) filing means a published comment file, a defined review calendar, and a decision that will be written down — all of which are observable in advance, unlike a quiet generic-standards listing that can appear with little warning. It also means the approval bar is higher: Cboe must persuade the SEC to accept an exception to a prohibition its own rulebook spells out, and the filing leans on surveillance arguments and the roughly 67 U.S.-listed +3x/-3x products already trading to make that case .

How Would a 3x Bitcoin or Ether ETF Actually Track Price?

Neither proposed fund would hold spot bitcoin or ether. Each seeks daily investment results, before fees and expenses, equal to three times the daily performance of a specified benchmark portfolio of first- and second-month CME futures contracts . Exposure comes primarily from CFTC-regulated futures listed on CME, COMEX or NYMEX, with the balance of assets held in cash and cash equivalents as collateral, and contract counts adjusted daily for creations, redemptions and to maintain the leverage target . That structure matters for anyone modeling tracking behavior: the reference price is the futures curve, not a spot index.

The benchmark itself is not static. It rolls monthly from the near-month contract into the next-month contract over a five-business-day window that begins on the sixth business day before expiry, moving roughly 20% of the expiring position each day . Staggering the roll across five sessions is a standard design choice to limit execution impact on any single day, but it also means the fund's effective exposure is a blend of two contract months for one week out of every month. When CME bitcoin futures trade in contango, that roll converts curve shape into a persistent drag layered on top of fees; in backwardation it works the other way.

The filing also anticipates the futures market becoming unusable. If benchmark contracts are unavailable because of price limits, accountability levels, margin requirements, exchange or FCM position limits, or similar constraints, the funds may substitute later-dated futures, benchmark-linked ETFs or ETPs, and listed options on futures, ETFs or ETPs . Those substitutions are a resilience feature, not a neutral one — options and later-dated futures carry different sensitivities than the front-month contract the benchmark nominally targets, so tracking quality can degrade precisely during the stressed sessions when a 3x holder cares most.

The mechanic most likely to surprise buyers is the daily reset. The 3x target applies to a single session, and the fund rebalances at each close to restore three times exposure against the new, larger or smaller asset base. Over multi-day holding periods, returns can diverge sharply in either direction from three times the underlying's cumulative move — the standard consequence of compounding and volatility drag. ProShares' own preliminary 3x registration statement carries the same caution that results over periods longer than one day can differ significantly from the stated daily objective .

Two directional consequences follow from that math:

• Choppy, range-bound tape erodes value. A sequence of alternating up and down days can leave the underlying flat while a daily-reset 3x product finishes materially below its starting point. Higher realized volatility widens the gap.
• Sustained trends compound in the holder's favor. In a clean multi-day move without meaningful retracement, daily rebalancing adds exposure into strength, and cumulative returns can exceed a static 3x calculation — the same mechanism that punishes chop rewards persistence.

None of this is unique to crypto; it is how every daily-reset leveraged product behaves. What is different here is the input. Bitcoin and ether realize higher daily volatility than the gold, silver, crude oil and natural gas sleeves filed alongside them , which magnifies both the erosion in sideways markets and the compounding in trends. Volatility Shares says as much about its existing lower-leverage funds, describing BITX and ETHU as products intended for investors who understand daily leveraged exposure and who monitor positions actively . A 3x version raises that monitoring requirement by half again.

3x Filing vs. Today's 2x Products vs. ProShares' Rival Bid

The 3x filing is an incremental step for Volatility Shares, not a debut. The sponsor already operates two leveraged crypto funds on the same exchange: BITX, a 2x bitcoin ETF listed June 27, 2023, and ETHU, a 2x ether ETF listed June 4, 2024 . As of July 9, 2026, BITX held $895.7 million in net assets at a 2.75% total expense ratio and ETHU held $661.5 million at 2.97% . Together that is roughly $1.56 billion of existing demand for daily-reset crypto leverage — the commercial case the new filing rests on.

The competitive wrinkle is that a second sponsor is chasing the same leverage tier through a different door. ProShares filed a preliminary N-1A registration statement on February 9, 2026 for an UltraPro Bitcoin ETF and an UltraPro Ether ETF, each targeting 3x daily exposure to the Bloomberg Bitcoin Index and Bloomberg Ether Index . An N-1A is the registration form used by Investment Company Act funds, which means ProShares is pursuing the '40 Act route while Volatility Shares uses a CFTC-registered commodity-pool wrapper. Two different regulatory paths, one destination.

Three practical differences matter for anyone comparing these:

• Cost is unknown at 3x. No ticker or fee level has been announced for either the Volatility Shares or ProShares 3x funds . The 2.75%–2.97% charged on the 2x pair is the only reference point available, and it is a high starting bar.
• Benchmark design differs. The Cboe-listed funds would track specified portfolios of first- and second-month CME futures , while ProShares references Bloomberg index levels . Tracking behavior around roll periods will not be identical.
• "First" is still undecided. Cboe's submission is the first exchange listing-rule request of its kind, but whichever product clears registration and lists first earns the label .

Decision Framework: Is a 3x Crypto ETF Actually For You?

A 3x crypto ETF is a short-horizon tactical instrument, not a portfolio holding. Each fund would reset its leverage target every trading session, so the compounded result over any multi-day window depends on the path the underlying takes, not just its net move. ProShares' own preliminary N-1A registration for its UltraPro Bitcoin and Ether funds warns that returns over periods longer than one day "can differ significantly" from three times the daily target . Holding period, not directional conviction, is the single largest risk variable in these products.

That framing matters because the cost base is already high before leverage does anything. Volatility Shares' existing 2x funds carry a 2.75% total expense ratio on BITX and 2.97% on ETHU as of July 9, 2026 . No fee level has been disclosed for the proposed 3x series , but a commodity-pool wrapper running CME futures with a monthly five-day roll is not a structure that gets cheaper as the multiple rises. Roll costs and financing drag compound daily alongside the leverage reset.

Match the instrument to the holding period

Cboe's proposal does not leave suitability entirely to the buyer. The filing states that member suitability obligations under BZX Rule 3.7 would apply, and that an information circular describing the products' special characteristics and risks must be distributed to members before trading begins . In practice that means brokers carry a documented obligation to assess whether a leveraged, daily-reset commodity pool matches a given account — the same gate that governs existing leveraged ETPs.

Three structural guardrails are written into the proposal itself: a minimum of 100,000 shares outstanding at commencement of trading, daily NAV disseminated to all market participants simultaneously, and an intraday indicative value published every 15 seconds during regular trading hours, with trading halted if NAV, IIV, or reference-asset information stops being broadly available . These reduce pricing-opacity risk. They do nothing to reduce compounding risk.

"Volatility Shares states that BITX and ETHU seek 2x daily exposure, do not invest directly in bitcoin or ether, and are intended for investors who understand the consequences of seeking daily leveraged investment results" — Volatility Shares LLC, product disclosures (source: Volatility Shares).

A practical screen before touching a 3x product, if it ever lists:

• Can you close the position the same session? If not, the daily reset is working against your thesis, not for it.
• Do you need spot exposure? These funds hold CME futures and cash collateral, never coins . Roll periods introduce tracking behavior spot ETFs do not have.
• Is 2x already sufficient? BITX held $895.7 million and ETHU $661.5 million in net assets as of July 9, 2026 — liquid, live, and available today without waiting on an SEC decision.
• Have you sized for a 33% adverse move? At 3x daily exposure, that is the arithmetic that wipes a single-session position.

The honest recommendation: for anyone whose horizon extends past a few sessions, the existing 2x products or unlevered spot ETFs remain the more coherent tool. The 3x sleeves are aimed at traders who already run intraday risk systematically and understand exactly why a 30% weekly gain in bitcoin may not translate into a 90% gain in a 3x fund .

Timeline: When Could Trading Actually Start?

No 3x bitcoin or ether ETF can trade until two separate approvals land, and neither has a fixed date. Under standard Section 19(b) procedure, the SEC must act within 45 days of the filing's Federal Register publication, a window it can extend to 90 days and ultimately stretch to 240 days before a final order is required . The SEC published SR-CboeBZX-2026-065 for public comment on August 14, 2026 under Release No. 34-106137 , which places the earliest possible decision point in late September 2026 and the outer deadline in the second quarter of 2027.

The second gate is the one most headlines skip. Approving Cboe's listing standard only settles whether the shares may be listed; it does not register the shares for sale. The filing states plainly that the trust's registration statement is not yet effective and that no shares will trade until it is . Two independent SEC processes must both clear, and the slower one sets the launch date. A favorable 19b-4 order accompanied by a still-pending registration statement produces exactly zero tradeable product.

Three things a trader would normally want to price this out simply do not exist yet:

• No listing date. Neither Cboe nor Volatility Shares has published a target commencement date for any of the six funds .
• No tickers. The 3x bitcoin and ether sleeves have no announced symbols, unlike the sponsor's live BITX and ETHU products .
• No fee levels. No expense ratio has been disclosed for the 3x series .

Context matters for how this proposal will be received. The filing landed in a soft tape: U.S. spot bitcoin ETFs recorded roughly $389.7 million in net outflows over August 10–14, 2026, including about $57 million on August 14 alone, while ether ETFs took in roughly $14 million in combined net inflows across a three-day stretch . Demand for leverage tends to be procyclical, so a request to triple daily exposure arriving during a redemption week is a useful reminder that filings are made on sponsor timelines, not market ones.

The concrete takeaway: treat this as a regulatory calendar item, not a trade. Watch the Federal Register docket for the SEC's first action window in late September 2026, then watch EDGAR for registration-statement effectiveness — until both clear, there is nothing to buy, and the practical exposure ceiling for U.S. listed crypto funds stays at 2x .

Frequently asked questions

Will Cboe's 3x bitcoin ETF definitely get SEC approval?

No. SR-CboeBZX-2026-065 is a 19b-4 listing-rule filing that the SEC published for public comment on August 14, 2026 under Release No. 34-106137 . Standard procedure gives the Commission 45 days from Federal Register publication to act, extendable to 90 days and ultimately up to 240 days . Approval of the listing standard alone would not put shares on screen either: the VS Trust registration statement is not yet effective, and the filing states shares will not trade until it is . Two independent gates, either of which can stall or fail.

Why can Cboe file for 300% leverage when the SEC caps funds at 200%?

Because the 200% ceiling in SEC Rule 18f-4, adopted in 2020, applies to registered investment companies under the Investment Company Act of 1940 — which is why every existing U.S. leveraged crypto ETF stops at 2x . VS Trust and its six series would instead be CFTC-registered commodity pools, sponsored by Volatility Shares LLC as commodity pool operator, and are not registered investment companies . That wrapper sits outside Rule 18f-4 entirely. The filing frames the CFTC/NFA supervision as an "additional layer of federal regulatory oversight — beyond what a physical commodity-based exchange-traded product would be subject to" . Whether the SEC accepts that framing is the central open question.

Is this the first 3x bitcoin ETF ever proposed?

It is the first exchange listing-rule request of its kind, not the first 3x crypto fund proposed. ProShares filed a preliminary N-1A registration statement on February 9, 2026 for an UltraPro Bitcoin ETF and UltraPro Ether ETF seeking 3x daily exposure to the Bloomberg Bitcoin Index and Bloomberg Ether Index, using a different regulatory path . Whichever product reaches listing first takes the "first to trade" label, and that race is unresolved. Worth noting for scale: the Cboe filing itself states roughly 67 U.S.-listed ETPs already target +3x or -3x performance — 51 Investment Company Act ETFs and 16 Securities Act ETNs — so 3x is not new as a category, only as crypto-linked commodity-pool exposure .

How is a 3x bitcoin ETF different from BITX, the existing 2x product?

The mechanism is largely the same; the multiple and the legal wrapper differ. BITX, the Volatility Shares 2x Bitcoin ETF listed on Cboe BZX on June 27, 2023, does not hold spot bitcoin and targets 2x daily performance . As of July 9, 2026 it showed $895.7 million in net assets with a 2.75% total expense ratio, alongside ETHU at $661.5 million and 2.97% . The proposed 3x funds would likewise hold CME futures rather than spot, reset daily, and sit inside a CFTC commodity-pool structure that the 200% rule does not reach. Practical consequence: a higher multiple compounds daily path effects more aggressively, so multi-day drift is larger in both directions than with a 2x product.

What happens if I hold a 3x crypto ETF for more than one day?

Your return can differ substantially from three times the underlying's cumulative move, in either direction. The 3x target applies to a single trading session and resets at each close, so multi-day results depend on the path prices take, not just the start and end points — the standard consequence of daily compounding and volatility drag. ProShares includes the same caution in its own preliminary 3x filing, warning that returns over periods longer than one day can differ significantly from the stated daily objective . Volatility Shares similarly describes its existing 2x funds as intended for investors who understand daily leveraged products . These are short-horizon tactical instruments, and the expense ratios on the comparable 2x funds — 2.75% and 2.97% — compound against a long hold as well.
