The Winklevoss twins file for a spot Zcash ETF
Updated: 6 days ago
TL;DR: Cameron and Tyler Winklevoss have filed with the SEC for a spot Zcash ETF that would hold ZEC directly and list on Nasdaq under the ticker WINK.
The filing
The Winklevoss twins filed a Form S-1 for a spot Zcash ETF, reported in early October 2026, with the fund holding ZEC directly and set to list on Nasdaq as WINK. The filing is corroborated by a Winklevoss Zcash ETF registration on the SEC’s EDGAR system.
It adds to an increasingly crowded race for a Zcash ETF, alongside Grayscale’s existing ZCSH fund, which recently crossed roughly $1 billion in assets under management.
Why it matters
Privacy coins have historically made US regulators wary, given the shielded, privacy-preserving design of assets like Zcash. A move to wrap ZEC in a mainstream, exchange-listed ETF is therefore a notable shift in what the market expects to get approved.
It reflects a broader pattern of issuers testing how far the current, more permissive regulatory mood extends — pushing beyond bitcoin and ether into more contentious assets.
What to watch
Approval is not guaranteed, and a privacy coin presents a sharper regulatory test than the large-cap assets that led the ETF wave. The filing is a signal of intent as much as an imminent product.
For businesses tracking digital-asset adoption, the direction of travel is clear: the ETF wrapper is becoming the default on-ramp for institutional exposure, and the list of eligible assets keeps widening.

Is this the only Zcash ETF?
No — it joins a crowded race that includes Grayscale’s existing ZCSH fund, which recently crossed around $1 billion in assets.
Why is a privacy-coin ETF notable?
Regulators have historically been wary of shielded, privacy-preserving assets like Zcash, so wrapping one in a mainstream ETF signals a more permissive environment — though approval is not guaranteed.
When a privacy coin starts queuing for an ETF wrapper, you know the regulatory weather has changed. The ETF has quietly become the default on-ramp for institutional crypto exposure, and the list of eligible assets keeps widening — even into the corners regulators once treated as off-limits. — Daniel Nikolla, Founder of Merx Marketing
