Winklevoss Zcash ETF files for Nasdaq, but it is not approved

A Winklevoss-backed spot Zcash fund wants to trade on Nasdaq under the ticker WINK and would hold ZEC directly, Cointelegraph and Decrypt report, citing the filing. Cameron Winklevoss signed the registration statement as chief executive officer on Oct. 6, 2026. For you, the filing is a first step toward a fund in your brokerage account, not an approval. Whether WINK can take the SEC's 2025 fast track to an exchange depends on three tests that ZEC has yet to be shown to pass.

WINK would hold ZEC directly, and a Winklevoss fund has signaled up to $100 million

Both reports describe WINK as a spot product that would own ZEC, the coin of the Zcash network. Cointelegraph adds that the fund would use no leverage or derivatives to pursue its investment objective. Your exposure would run through the coin itself rather than through futures or borrowed money.

The reports also name a possible early buyer. Winklevoss Capital Fund has indicated interest in buying up to $100 million of the fund's shares. The indication is non-binding. It marks a ceiling stated at filing rather than money already in the fund.

Decrypt adds a governance detail. The trust named Cypherpunk Technologies, a Winklevoss-backed company, its "Zcash Ecosystem Partner." The partner would advise on protocol matters and coinholder voting.

Decrypt calls the filing only a first step and says the SEC must still sign off before trading can begin. That raises the question that decides your timing: what kind of sign-off? A 2025 rule change gives two possible answers.

Since 2025, a qualifying crypto fund can list without its own SEC approval

On Sept. 17, 2025, the SEC approved generic listing standards for commodity-based trust shares. They let Nasdaq, Cboe BZX and NYSE Arca list a product that meets the standards without Commission approval of each individual product (Rule 19b-4(e)). A product that misses the standards still needs a rule filing with the SEC.

The standards turn on the coin a fund holds. Each commodity in the trust has to pass at least one of three tests:

1. It trades on a market in the Intermarket Surveillance Group, meaning a market from which the listing exchange can obtain trading information.
2. Futures on it have been listed for at least six months on a designated contract market, and that futures exchange has a surveillance-sharing agreement with the listing exchange.
3. For a first listing only, an ETF already listed on an exchange has at least 40% of its net asset value exposed to the coin.

Here is how that plays out for WINK. If ZEC passes any one of the three tests, Nasdaq could list the fund on the generic route without SEC approval of the product. If ZEC passes none, Nasdaq would first have to file a rule change with the SEC.

Grayscale's Zcash fund came first, but its filings stop in July

WINK follows an earlier Zcash effort. Grayscale's Form S-3, filed Nov. 26, 2025, set out Grayscale's intention to list its Zcash trust's shares on NYSE Arca under the symbol ZCSH.

Grayscale's Amendment No. 3, filed July 31, 2026, still described that NYSE Arca listing as intended. The amendment named Coinbase Custody Trust Company as the trust's custodian and left the sponsor fee rate blank.

Cointelegraph reports that ZCSH already trades in the U.S. and Decrypt dates its conversion into a spot ETF to August, after the July 31 amendment, so the exchange and listing route remain unconfirmed.

Grayscale's filing puts numbers on ZEC's risks

The July 31 amendment records a recent shock. In June 2026, a security researcher engaged by ZODL disclosed a critical vulnerability in Zcash's Orchard shielded pool, and an emergency network upgrade fixed it. ZEC's market price fell about 50% after the disclosure and has since substantially recovered.

Set against that drop of about half, the year's swing was far wider. Grayscale's ZEC Index Price ranged from $35.01 to $685.96 in the 12 months ended June 30, 2026, so the high was about 20 times the low. The range spans the year's lowest and highest readings, so it measures volatility rather than a one-year return.

On the regulatory side, the amendment notes that the SEC terminated its investigation or enforcement action into the Zcash Foundation in January 2026. That closes one inquiry into one organization. ZEC's legal status and the treatment of privacy coins stay where they were.

An amended S-1 and Nasdaq's next filing will show WINK's route

The S-1 dated Oct. 6, 2026, is still preliminary. It leaves the date and figures of its underlying-index trading-platform table blank, along with most expense lines, including the listing fee. The SEC registration fee shows $0 with an unexplained asterisk.

Two places will show the next step. On SEC EDGAR, look for an amended S-1 that fills in those blanks. From Nasdaq, a listing under the generic standards would mean the fund met them. A rule filing with the SEC would mean the route that needs Commission approval.

The S-1's table of contents also lists sections on custody of the trust's assets, a seed capital investor and conflicts of interest. Those three sections are worth reading first when the full prospectus text is available.

As of Oct. 7, 2026, one question decides the timing: which of the three tests ZEC passes, if any. That answer, or a Nasdaq rule filing, will set WINK's path to a trading date.
