Grayscale's Zcash ETF would erase its net inflows within eight trading days at late-September redemption rates
Grayscale's ZCSH, the first US spot Zcash ETF, lost $93.56 million to outflows in one week, leaving $212.56 million of net inflows since its August launch. Its assets fell further, to about $751 million from a September peak as high as $979 million, with ZEC's price accounting for much of the drop.
The Investor · Invest desk
What happened
- ZCSH began trading on NYSE Arca on August 25, 2026, after Grayscale converted its existing Zcash Trust into the first US-listed spot ZEC fund.
- The fund's best week, ending September 18, brought in $98.2 million of new money.
- Redemptions then ran at $30.25 million on September 30 and $26.93 million on October 2, with several other days in the $26 million to $30 million range.
- Grayscale announced a 3-for-1 split on September 18, and split-adjusted trading began September 30, the day of the fund's largest reported single-day redemption.
Why it matters
- What it costs cost At its 2.5% expense ratio, ZCSH now earns Grayscale about $18.8 million a year against $22.9 million to $24.5 million at the September peak, so both redemptions and ZEC's slide come out of the issuer's revenue.
- Who's exposed exposure A fund that held about 3.5% of ZEC's supply at its height needs less of the token whenever redemptions run, so ZEC holders now carry ZCSH's flow risk.
- What it sets up precedent ZCSH took up to 32.5% of spot crypto ETF turnover in its strongest week and still shed assets within six weeks, so a future single-token launch's trading share says little about how long its money stays.

The redemptions explain only part of the fall in ZCSH's assets. Crypto Briefing puts the September peak at roughly $915 million to $979 million, so the slide to about $751 million took out $164 million to $228 million [23]. Cumulative net inflows over the same late-September stretch went from around $268 million to $212.56 million, a net $55.44 million out [11]. On those figures, redemptions account for 24% to 34% of the shrinkage [12]. The rest is ZEC, which pushed past $1,500 after the fund's debut before settling lower [8].
The report's own numbers do not fully reconcile. Its $93.56 million outflow week [2] is $38.12 million larger than the entire decline in cumulative net inflows it gives for late September and early October [18]. The weekly figure may be gross redemptions before new money came in, or the two may cover different windows. The report does not say which. Take the larger number anyway and flows explain 41% to 57% of the fall in assets, leaving at least 43% to price [13].
Launch money was always the smaller part of the asset base. ZCSH is a converted trust [1]. Of its roughly $751 million, about $538 million, or 72%, is not accounted for by post-launch net inflows; that portion is the trust's existing ZEC plus price moves on everything the fund holds [19]. The money that arrived with the launch is the $212.56 million on top, about 78% of the $271 million cumulative peak reached by mid-September [3] [14].
Three readings fit. The first is that the late-September redemption days were launch-month traders leaving, and they taper. The second is that they keep coming. Run the September 30 and October 2 rates back to back with no new money and the remaining net inflows are gone in seven to eight trading days [20]. After that, redemptions start drawing on the trust's original holdings. In the third, flows settle and ZEC's price sets the asset figure regardless, as it did for much of the September decline [12].
Grayscale's response so far, the split, was aimed at liquidity, according to Crypto Briefing [24]. The report does not mention a fee cut [17]. The change Grayscale made is to how the shares trade, not to what they cost to hold [9].
I think the evidence supports a narrower claim than fragile demand for single-token spot ETFs. It covers one fund, 38 days from debut to the October 2 redemption [16], whose worst week of outflows came to 95% of its best week of inflows, $93.56 million against $98.2 million [15]. ZCSH is giving back part of its launch and remains net positive [7]. The fragility thesis gains real support if those cumulative net inflows turn negative in October, and it weakens if the $26 million-plus redemption days stop [6].
What to watch
- Whether Grayscale cuts ZCSH's 2.5% expense ratio if redemptions persist after the split.
- Whether a reconciled daily creation and redemption series settles the gap between the $93.56 million weekly outflow and the $55.44 million decline in cumulative net inflows.
- Whether the 3-for-1 split produces the liquidity Grayscale was aiming for, measured by ZCSH's share of spot crypto ETF turnover.

A fund that held roughly 3.5% of ZEC's supply is a meaningful source of supply and demand pressure for the token: inflows mean it must hold more ZEC, redemptions run the other way.
- [11]
Cumulative net inflows declined by a net $55.44 million over late September and early October.
- [12]
Net redemptions measured by the cumulative inflow decline account for about 24% to 34% of the fall in assets; price accounts for the remaining 66% to 76%.
