SEC approves Cboe BZX rule change for six Volatility Shares 3x ETFs

The Securities and Exchange Commission approved a Cboe BZX rule change on Oct. 2 that allows six Volatility Shares ETFs to come to market, each aiming to deliver three times the daily return of an underlying asset. Two of them are crypto funds, tracking bitcoin and ether. The other four cover gold, silver, crude oil and natural gas, which makes the order as much an expansion of the commodity-leverage shelf as a crypto event, even though crypto is where the change of substance sits.

CoinDesk frames the approval as a milestone for a specific reason: until now, crypto funds in the U.S. had been capped at 2x leverage. A suite built for 3x daily returns pushes past that ceiling, and for traders who have watched bitcoin's volatile years from the sidelines, the third multiple is the point of the filing rather than a marketing detail.

None of the six can trade yet. The issuer still needs the SEC to declare its registration statement effective, and the Oct. 2 order sets no deadline for that step. Approval of a rule change and effectiveness of a registration are separate gates, and only the first one has opened.

It is worth being precise about what the crypto funds will hold, because "bitcoin ETF" has become shorthand for a spot product with a custodian. These will hold regulated futures tied to bitcoin and ether, not the tokens themselves, per the CoinDesk report. The structure suggests no token custody arrangement is required at all, since there is no coin to hold. The trade-off arrives in the futures market's own costs.

Keeping leverage pinned at exactly 3x requires the fund to rebalance every day: buy more futures after a gain, sell some after a loss. Those flows are mechanical, they usually hit near the close, and they scale with the fund. The bigger the product grows, the bigger the impact its own rebalancing has on the market it tracks.

The same reset does something quieter over multiple days. A 10% rise followed by a 10% fall leaves the underlying down 1%; the same two days at 3x produce a 30% gain and then a 30% loss, ending 9% lower. The more the price whipsaws inside a range without a consistent directional trend, the more the leveraged product gives up. That is volatility decay, and a flat market is when a holder eats the most of it.

Blockstream chief executive Adam Back, quoted in the newsletter, describes the mechanism as auto-releveraging strategies that bleed capital in a sideways chop, and notes the effect sharpens against a high-volatility underlying such as bitcoin. Bloomberg senior ETF analyst Eric Balchunas framed the audience question in a single line on X: "Leveraged ETFs are for trading, not investing."

Volatility Shares does not argue with any of it. In its preliminary prospectus, filed as part of a Form S-1 registration statement, the firm writes that the more volatile the benchmark, the greater the potential for volatility decay. The same document says an investment in 3x Bitcoin ETF "is not suitable for all investors, may be deemed speculative, and should be considered only by persons who can bear the risk of total loss associated with an investment in 3x Bitcoin ETF."

That is an issuer describing its own product in the plainest available terms, and for an adviser it carries more weight than any fact sheet, because it speaks to holding period. A product whose own filing contemplates total loss belongs in a client account only with a defined exit, sized and reviewed the way a trading position is rather than the way a strategic sleeve is.

Futures add a further cost on top of the decay. As contracts approach expiry, the fund sells them and buys later-dated ones, so the roll recurs as each contract ages out — the third charge stacked into the wrapper, after the reset drag and the leverage itself.

For now the practical fact is procedural. Six products are approved on paper, two of them offering 3x exposure to bitcoin and ether through futures rather than tokens, and the order sets no clock for the registration statement to be declared effective. Until that happens there is nothing here to buy, and the shelf technically holds a leverage level no U.S. crypto fund has been able to reach before.
