Grayscale’s Zcash ETF just had its first bad week on Wall Street. The fund, ticker ZCSH, saw investors pull 93.56 million USD over the week ended October 2, according to SoSoValue data — the first net outflow week for the fund since late August.

The Hook: A Sharp Reversal After a Hot September
For regular investors, this story is a classic example of how fast sentiment can flip in crypto. ZEC, the token behind privacy-focused Zcash, was one of September’s standout performers — gaining roughly 102% in a month at one point. That rally pulled a flood of money into the newly converted ETF. Now, some of that money is heading for the exits.
The outflows were not spread evenly. Daily redemptions reached 30.25 million USD on September 30 alone, followed by another 26.93 million USD on October 2, according to SoSoValue. Those two days did most of the damage in a week that wiped out a meaningful chunk of the fund’s September gains.
On-Chain Evidence: What the Fund Numbers Show
Here is where things stand for ZCSH, the Grayscale fund that gives investors exposure to ZEC without holding the coin directly:
- 93.56 million USD — net outflows for the week ended October 2, the first negative week since late August
- 751 million USD — approximate total net assets remaining in the fund
- 212.56 million USD — cumulative net inflows since launch, still positive
- Roughly 100 million USD — invested by Digital Currency Group on September 8 through an authorized participant transaction
To put that in perspective: by late September the fund had crossed 1 billion USD in assets as ZEC climbed above 1,000 USD for the first time in years. At its strongest, mid-September, the fund had attracted around 271 million USD in cumulative inflows, including approximately 98.2 million USD in a single peak week.
The Core Conflict: Price Drag or Investor Exit?
Not all of the fund’s shrinkage is investors selling. Because ZCSH simply holds ZEC, the dollar value of its assets falls when the token’s price falls — even if nobody redeems a single share. And ZEC has fallen hard.
CoinGecko historical data shows the token closing at 1,653.12 USD on September 26, then sliding to 1,483.24 USD on September 28, 1,438.21 USD on September 30, and 1,301.16 USD on October 2. It closed October 3 near 1,304 USD — a decline of roughly 21% from the September 26 peak, and about 23% below the levels that made headlines just a week earlier.
The futures market told a similar story. ZEC perpetual open interest on OKX declined from 236.8 million USD on September 18 to 165 million USD on September 28, a sign that leveraged traders were unwinding their bets as the price retreated. In plain terms: fewer people were borrowing money to bet on ZEC going higher.
A Share Split in the Middle of the Storm
In a coincidence of timing, Grayscale completed a three-for-one forward share split of ZCSH on September 30 — the very same day the fund saw its 30.25 million USD single-day outflow. According to Grayscale’s September 30 SEC filing, the fund had 7,989,300 shares outstanding before the split, each with a net asset value of 111.41 USD. After the split, the count rose to 23,967,900 shares.
A share split does not change the value of anyone’s investment — think of it like swapping one 20-dollar bill for four 5-dollar bills. It simply makes each share cheaper, which can make the fund more accessible to smaller investors. But the optics of a split landing on the biggest outflow day of the week added to the noise around the fund.
Market Implications: What This Means for Your Portfolio
The bigger picture matters more than any single week. Grayscale converted its long-running Zcash Trust into the ZCSH ETF on August 25, listing it on NYSE Arca. The fund launched with roughly 304 million USD in assets, rose past 400 million USD as ZEC climbed, and then crossed 1 billion USD at the September peak. Even after the rough week, it remains a roughly 751 million USD fund — far from a failure.
For everyday investors, there are two takeaways. First, ETF flows are a sentiment gauge, not a crystal ball: the same Wall Street money that piled in during September can leave quickly when prices turn. Second, a token that roughly doubled in a month was always likely to see profit-taking — the outflows and the price drop are two sides of the same coin, and the data does not prove one caused the other.
The Verdict
Zcash’s first ETF outflow week is a normalization, not a collapse. Cumulative inflows remain positive, the fund is still large by niche-crypto standards, and the token — after a parabolic September — is digesting its gains. Watch whether outflows continue into next week and whether ZEC holds the 1,300 USD area. If the bleeding stops, this will read as a healthy cooldown after a hot run. If it deepens, the September rally may be remembered as the top — for now.

93.56M pulled in one week and people still call this a healthy pullback. first red week since august, lets see if the etf flow story survives contact with reality
^ the september inflows were mostly momentum money, that stuff reverses fast when the chart turns
healthy pullback or not, ZEC held up way better than the flow number suggests. 1300 is the line that matters, agree there
zec holding near 1,300 while zcsh bleeds is the actual tell. the coin outperforming its own wrapper means redemption is tax planning, not conviction loss
the tax angle checks out too. anyone who rode the 102 percent september candle can redeem the wrapper, keep the coins, and defer the gain. thats not conviction loss
watching 1,300 too but that 102 percent september candle leaves a lot of air underneath. monthly closes matter more than any weekly flow print right now
Olenna Prieto the 102 percent candle is exactly why a monthly close above 1300 matters more than any weekly print. the air underneath has to get bought or the flow story resets lower
two days, 30.25M and 26.93M, did most of the damage. that clustering smells like one or two big redeemers, not broad sentiment turning
if its one AP working a window the outflow prints stop the moment the window closes. watch for two clean green days and the whole narrative flips overnight
agreed, 30.25M and 26.93M back to back is one desk working an exit window. broad sentiment doesnt redeem in round blocks like that
30.25M and 26.93M on consecutive days, agreed that reads like one redeemer working a window, not sentiment turning. flows flip green above 1,300 and the narrative resets in a week
two prints near 30M back to back is exactly what a single large redeemer looks like on a flow chart. agree the 1,300 reclaim matters way more than this redemption noise
gritz_k one redeemer working a window fits the clustering perfectly. two consecutive prints near 30M is not a crowd changing its mind, it is an AP doing a job
First outflow week since August and ZEC sliding toward 1,300 at the same time. The September ETF enthusiasm is getting stress tested for sure.
One bad week after weeks of inflows is barely a trend. Watching whether 1,300 holds is the real signal here, not the weekly flow number.
stress tested is right. september enthusiasm was 90 percent momentum chasers, lets see the next full month of filings before calling the etf trend dead
1,300 was the breakout shelf before the september run. if it holds the etf story is intact, if it goes then the 102 percent month was the exit
the september run launched off 1,300 twice. third touch with 93M of outflows already absorbed is the test most people miss until its behind them
93.56M out is basically two days of flows in a market this size. the zec etf story was always a slow burn, one red week after five green ones is noise
first red week since august right after a 102 percent month and the fund still held the low 1300s. ill take that stress test result over the headline print
93.56M out on a week where price held the low 1300s is actually divergence in ZECs favor. if outflows could not break 1300 the sellers may already be spent
102 percent september candle and the first red week gets the scary headline. 93.56M on a fund this size is noise, 1,300 decides the story
everyone fixated on the first red week forgets zcsh absorbed a month that saw zec double. 93.56M out after that run is just profit taking with extra steps, the wrap story aint dead
flowdrift_ right, the fund absorbed a month of zec doubling without breaking. one 93.56M week after that is a rounding bruise, the wrap story needs a monthly close below 1300 to actually die
zkcandle_ a monthly close below 1300 is a high bar when every redemption so far got absorbed without breaking the shelf. if tax-driven selling could not do it, what does
first red week since august right after a 100 percent month is just profit taking with a ticker. watching whether inflows come back below 1,300
watching the zec/zcsh spread instead of the flows. zec holding the low 1300s while the wrapper bled all week is the cleaner tell on who is actually leaving
