Grayscale’s Zcash ETF (ZCSH) has filed for a 3-for-1 forward share split, days after the fund accounted for 32.5% of all spot crypto ETF trading volume in the biggest week of its short life. The split, disclosed in a filing with the US Securities and Exchange Commission, will give shareholders two extra shares for each one they hold at the close of trading on September 28.
The filing lands in the middle of a violent run for Zcash itself. The privacy coin’s ZEC token climbed as high as $1,521 early Friday, an effective all-time high, before easing back to around $1,440. ZEC is up roughly 175% in a month, and its market capitalization has pushed above $20 billion, the highest level since 2016.
A third of all ETF turnover, from a fund under $1 billion
ZCSH recorded $11.42 billion in trading volume in the week ending September 18, according to data compiled by FinScans and CoinMarketCap. That was 32.5% of all spot crypto ETF turnover for the week, a striking share for a fund that holds under $1 billion in assets and launched on August 27.
The volume was also wildly concentrated. About $11 billion of the week’s total changed hands on September 16 alone, the day the Federal Reserve delivered a 25 basis point rate hike and the Senate rejected the CLARITY Act on a 50-49 procedural vote. Analysts caution that the spike says more about arbitrage and volatility than about investors accumulating Zcash. Traders used the new fund as a fast, liquid vehicle to reposition around the macro shocks, then stepped back.
The distinction matters for anyone reading the volume as demand. Net inflows build an ETF’s assets over time; churn does not. Zcash ETFs rank third among altcoin products by assets, behind XRP and Solana, and ZCSH’s asset growth tracks the token’s price run far more closely than any steady accumulation story.
| Metric | Value |

| Weekly volume (to Sept 18) | $11.42 billion |
| Share of all spot crypto ETF volume | 32.5% |
| Single-day volume (Sept 16) | about $11 billion |
| Fund launch | Aug 27, 2026 |
| ZEC one-month gain | about 175% |
| ZEC Friday peak | $1,521 |
| Market capitalization | above $20 billion |
Why a split, and why now
The split itself is mechanical. Grayscale’s press release walks through the arithmetic: an investor holding 10 shares at $300 each, $3,000 in total, would own 30 shares at $100 after the split, with the same $3,000 of value. Nothing about the fund’s holdings changes. What changes is the ticket size.
Grayscale’s stated reason is accessibility. ZEC has gained about 2,800% over the past year, and the per-share price of the trust had climbed to a level the firm considered too high for comfortable retail participation, according to Cointelegraph. Forward splits of this kind are routine for funds whose unit prices drift far from where they launched. ZCSH simply got there in three weeks rather than three years.
The fund’s short history explains the speed. Grayscale converted its long-standing Zcash Trust into the spot-listed ZCSH on NYSE Arca late in August, after a record of swinging premiums and discounts to net asset value, at one point 240% premiums and, at another, 55% discounts. The listed, arbitrageable structure was the fix for that problem, and the split extends it. When a trust trades far from the value of its coins, big investors step in to close the gap, and the wrapper now lets them do that in market hours.
Paradigm’s Huang backs the network
The price run has pulled in new money. On Thursday, Paradigm co-founder Matt Huang disclosed that the crypto investment firm had bought an unspecified amount of ZEC and threw his weight behind the coin’s developer fund, as first reported by The Block.
“Zcash is a private complement to Bitcoin,” said Matt Huang, Paradigm co-founder, in his public case for funding the project.
Huang’s argument stretches beyond price. He framed sustained development funding as important as AI-driven cyber capabilities advance and quantum computing moves closer to practice, a nod to the zero-knowledge cryptography Zcash runs on. Whatever one makes of the investment case, a Paradigm co-founder publicly backing a privacy coin marks a shift from the quiet years when privacy tokens traded as a side bet with thin institutional cover.
The endorsement also landed on fertile ground. Fortitude, a Zcash mining operation, recently hired a former Hut 8 CEO as it prepares for a public listing, a sign that the ecosystem’s infrastructure layer is professionalizing alongside the price.
NU7 sets up a faster Zcash in November
The token’s fundamentals are in motion too. Zcash developers are targeting November 5 for the NU7 mainnet upgrade, with testnet activation on October 6 and a final go or no-go decision scheduled for October 20 after testnet performance is assessed, developer Sean Bowe said last week, as covered in Cointelegraph’s report.
NU7 would cut Zcash’s target block spacing from 75 seconds to 25 seconds, disable version 4 transactions and integrate the Network Sustainability Mechanism. The chosen NSM configuration preserves the coin’s halving schedule, with previously removed supply reintroduced beginning February 2031. Bowe said the upgrade would not introduce new transaction formats and should not significantly affect wallets, though full nodes, indexers and block explorers may need adjustments.
The community vote was about as lopsided as these things get. 98.9% of voting ZEC holders backed preserving halvings, and 99.9% of the ZEC-weighted vote supported the faster block proposal. Faster blocks mean quicker confirmations for shielded payments, the use case Zcash has always claimed as its own and the one its cryptography was built around.
The privacy sector is suddenly the hot trade
Zcash is not moving alone. Glassnode data cited by Cointelegraph showed the privacy coin sector trading 213% above its level at Bitcoin’s October 2025 peak, while a comparable basket of privacy tokens excluding ZEC was up about 85% over the past year. Monero changed hands above $520 on Saturday, up more than 9% on the day.
The drivers mix the old and the new. On the old side sits capital rotating into assets that operate outside mainstream financial plumbing, a theme that strengthens every time regulators stall. On the new side sit investors treating strong cryptography as a hedge against both AI-powered surveillance and, further out, quantum decryption. Paradigm’s developer-fund argument leans on the second, and it gives the trade an intellectual spine it lacked during the last cycle.
The regulatory backdrop does its part. The Senate’s failure to advance the CLARITY Act left crypto market structure unresolved, and money that might have waited for clarity rotated instead. Zcash’s shielded transactions, which conceal addresses and amounts with zero-knowledge proofs, are the most direct expression of that trade available to US investors through an ETF wrapper.
The risks on the other side
The same facts cut both ways. A fund that turns over more than ten times its assets in a week is being traded, not held, and one-day concentration of that magnitude usually fades. ZEC itself remains a high-volatility asset with a history of retracing hard after vertical moves; the token already pulled back from $1,521 within hours of the Friday peak.
There is also the older lesson from the trust era. Premiums and discounts made ZCSH’s predecessor a difficult holding for years, and while the ETF structure narrows those gaps, a fast-moving underlying token can still push the fund away from its net asset value during stress. Grayscale’s own filing language flags heightened volatility as a core risk of the product.
Regulatory attention on privacy tools has not disappeared either. Zcash survived years of delistings on major venues, and a price run built partly on regulatory frustration invites scrutiny of exactly that property. None of this cancels the momentum, but it defines the downside.
What to watch from here
Three dates frame the next stretch. September 28 brings the share split’s effective date. October 6 starts NU7’s testnet activation, followed by the October 20 decision on mainnet timing. Between those, the question is whether ZCSH’s volume normalizes back toward its size or the fund keeps punching far above its weight.
The bear reading of last week is that it was one wild macro day routed through a new fund. The bull reading is that a coin written off for years found a fresh buyer base and a working ETF wrapper at the same time. The split lowers the entry ticket just as the network prepares its biggest technical change in years. Whether that timing was careful planning or luck, Zcash has not had a month like this since 2016.
