Cameron and Tyler Winklevoss have filed with the U.S. SEC to launch a spot Zcash ETF, bringing their latest crypto fund effort more than 13 years after their first spot Bitcoin ETF filing.
The new Nasdaq product comes as Zcash native token ZEC rallies above 5%, now trading at $1,357.
ETF expert Nate Geraci confirmed that Winklevoss Asset Services filed a Form S-1 registration statement with the U.S. SEC on Oct. 6, 2026, to launch the WINK ETF on Nasdaq.
The proposed fund would be a spot Zcash ETF, meaning it would hold actual ZEC instead of futures or other derivatives. The fund would use a cash creation and redemption model, where authorized participants provide dollars, and the fund uses that money to buy ZEC.
The new filing also connects to the twins long history in the crypto ETF market. In July 2013, Cameron and Tyler Winklevoss filed one of the first proposals for a spot Bitcoin ETF.
The timing also comes after Grayscale’s Zcash ETF, which the reference says has surpassed $900 million in assets under management since its launch.
The twins’ interest in Zcash also extends beyond the proposed ETF. Their publicly traded digital asset treasury firm, Cypherpunk Technologies, has accumulated more than 290,062 ZEC, worth roughly $152 million based on the reference.
That represents about 1.76% of Zcash’s circulating supply. The company has also set a longer-term goal of holding at least 5% of the total supply.
The twins have further strengthened their connection to the project by bringing Zooko Wilcox, Zcash’s founder, in as a strategic adviser.
The new spot ETF filing has added to the strong buying interest in ZEC, which has already been one of the best-performing crypto assets this year.
The token is trading near $1,350 after a strong recovery from its summer decline. Demand has also grown as some traders look to Zcash for more privacy compared with Bitcoin.
