SEC clears first 3x bitcoin and ether ETFs: a 30-day replay shows what daily resets do

The Securities and Exchange Commission on October 2 approved a Cboe BZX rule change that allows six exchange-traded funds from Volatility Shares, each aiming for three times the daily return of its underlying asset, CoinDesk reported. The lineup covers bitcoin, ether, gold, silver, crude oil and natural gas. Until now, US crypto funds had been capped at 2x leverage.

The funds cannot trade yet. According to CoinDesk, the issuer still needs the SEC to declare its registration statement effective, and the order sets no deadline. The products would hold regulated futures tied to bitcoin and ether, not the coins themselves.

What "3x daily" means, and what it does not

The promise is three times the return of a single day. It is not three times the return of a week or a month. Because the fund resets every day, losses and gains compound on a new base, and that changes the outcome whenever the price whipsaws.

CoinDesk gives the textbook case. Bitcoin rises 10% one day and falls 10% the next, ending down 1% (1.10 x 0.90 = 0.99). A 3x fund gains 30% and then loses 30%, ending down 9% (1.30 x 0.70 = 0.91). The underlying lost 1%, the fund lost 9%.

Our own replay on real bitcoin prices

To put numbers on it, we took Coinbase's BTC-USD daily candles and compounded a hypothetical 3x daily return across them. This is an illustration, not a fund result: it ignores management fees, financing costs and the cost of rolling futures, all of which would reduce a real fund's return.

Window (Coinbase daily closes)	Bitcoin	Simple 3x of that move	3x reset daily, compounded
30 daily candles ending Oct. 5 (close of the first to latest price)	+7.2% ($79,832 to $85,616)	+21.7%	+19.4%
14 daily candles ending Oct. 5	-1.1%	-3.4%	-3.8%

In a month with a clear upward drift, the daily-reset fund came in about 2.3 points under a flat 3x. In a choppy two weeks where bitcoin ended slightly lower, it lost somewhat more than three times the decline. Neither gap is dramatic over these windows, and both would widen in a more violent market. That is the point: the product is designed for a day, and the longer it is held the more the path matters.

The risks the issuer itself flags

CoinDesk quotes Volatility Shares' preliminary prospectus: "The more volatile the benchmark, the greater the potential for volatility decay." The same filing says an investment in the 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."

Two more mechanics from the same report matter to anyone who trades around the close:

• Daily rebalancing. To keep leverage at 3x, the funds must buy more futures after gains and sell more after losses. CoinDesk notes those flows typically cluster near the close and can amplify intraday moves, more so as the funds grow.
• Roll cost. As futures approach expiry, a fund sells them and buys later-dated ones, which often cost more. CoinDesk says standard bitcoin futures ETFs faced the same drag when they launched in 2021.

Bloomberg's senior ETF analyst Eric Balchunas, quoted in the CoinDesk piece, put it this way: "Leveraged ETFs are for trading, not investing."

Who this is for, and what changes now

Nothing changes for spot holders today. The funds are not trading, and the approval does not make bitcoin more or less likely to rise. The practical effect is on short-term traders, who gain a way to take amplified, defined-risk-per-day exposure inside a brokerage account, and on market structure, since a large 3x fund adds a predictable late-session flow. Bitcoin traded near $85,600 on Coinbase on Monday afternoon, up about 0.3% over 24 hours, according to our crypto prices board.

This sits next to a larger regulatory move the same day. See our report on the CFTC's 60-day comment period on leveraged retail crypto trading. What to watch next: the date the SEC declares the registration effective, and the first week of volume.
