$110M Zcash Buying Plan Anchors ETF Filing Rally as ZEC Gains 12%

CoinGecko data shows a single institutional buyer committed $110 million to purchase ZEC over 12 months, contingent on the SEC approving a spot Zcash ETF filed Monday. ZEC jumped 12% by 14:00 UTC Tuesday, outpacing bitcoin's 11.6% gain to $71,587 and a 7.2% broad-market advance that pushed total crypto capitalization to $2.45 trillion. The commitment appears in an amendment to the Zcash ETF Trust's Form 8-A/A filed with the SEC on August 18. per CoinGecko, the document identifies the buyer as a "qualified institutional buyer" under Rule 144A and states the $110 million will be deployed in monthly tranches beginning the first business day after the fund's effectiveness. No custodian or prime broker is named in the public filing. Bitcoin's rally provided tailwinds. BTC has added 13% over the past seven days, with the 7-day close series climbing from $63,417 to $69,755. Ether dominance held at 11.2% while bitcoin dominance ticked up to 58.7%, suggesting the altcoin move was beta-driven rather than rotation. The Zcash filing is the first U.S. spot crypto ETF registration to pair a binding purchase commitment with the initial application. Previous filings, including the 11 spot bitcoin ETFs approved in January, disclosed authorized participants and seed capital but not a pre-committed buyer of the underlying asset. The structure mirrors the capital formation conditions some commodity ETFs used in the 2000s to assure the SEC of initial liquidity. Figures from the desk show zEC traded at $38.42 on CoinGecko at 14:00 UTC Tuesday, up from $34.30 24 hours earlier. Volume hit $412 million, roughly 3.5x the 30-day average. Open interest on CME ZEC futures (listed June 2025) rose 22% to 1,840 contracts, indicating derivatives desks are hedging the spot move. The SEC now has up to 240 days to rule. The first comment-period deadline is September 27. CoinGecko data shows if approved, the $110 million mandate would represent roughly 18% of ZEC's current circulating supply of 16.5 million coins at Tuesday's price.

What the filing structure signals

The 8-A/A amendment is unusual because Form 8-A typically registers a class of securities for exchange listing, while ETF approvals proceed on Form S-1 or 19b-4. The dual-track approach suggests the sponsor is seeking exchange listing readiness in parallel with the ETF effectiveness order, a tactic the bitcoin ETF sponsors adopted only after their 19b-4 approvals.

Custody and redemption mechanics unresolved

per CoinGecko, the filing does not specify whether the $110 million buyer will hold ZEC directly or through the ETF's custodian. It also leaves the redemption mechanism for the monthly tranches undefined. Analysts at Kaiko noted that without a named custodian, the commitment functions more like a letter of intent than a binding subscription agreement.

September comment period is the first hard deadline

Interested parties have until September 27 to submit comments on the 19b-4. The SEC's Division of Trading and Markets typically issues a notice of filing within 10 business days, which would land around September 2. That notice starts the 45-day initial review window, after which the Commission can extend for another 90 days and then a final 60 days.
