Winklevoss Brothers File for Spot Zcash ETF with SEC

Tyler and Cameron Winklevoss are making strides in the cryptocurrency market with their recent filing for a spot Zcash ETF. Their firm, Winklevoss Asset Services, LLC, submitted a Form S-1 registration statement to the US Securities and Exchange Commission on October 6, 2026.

The proposed product, known as the Winklevoss Zcash ETF, is designed to hold ZEC, the native token of the Zcash network, directly. If approved, it is expected to trade on Nasdaq under the ticker WINK. The fund will operate under a cash-create and cash-redeem model, where authorized participants exchange cash for new shares, while the fund itself will manage the purchase of underlying ZEC tokens.

Custody for the ETF will be handled by Gemini Trust Company, LLC, the Winklevoss twins' own cryptocurrency firm. Additionally, the filing indicates a partnership with Cypherpunk Technologies for services related to the Zcash network.

This filing comes on the heels of Grayscale's Zcash ETF, which launched on NYSE Arca on August 25, 2026, becoming the first US spot ETF for Zcash. Grayscale's fund quickly amassed over $500 million in assets under management within two weeks of its launch, charging a management fee of 2.5%, which the Winklevoss team will need to consider as they finalize their offering.

The regulatory landscape has shifted favorably for Zcash, as the SEC concluded a review of Zcash-related matters in January 2026 without taking enforcement action. This development has opened the door for new products like the Winklevoss Zcash ETF.

As the ETF market evolves, the Winklevoss filing marks a significant step for Zcash, highlighting the competitive dynamics in the cryptocurrency space, especially as institutional interest continues to grow.
