Zcash ETF Records $93.6M Exit as ZEC Falls 23%, NU7 Looms

ZCSH Posts First Weekly Outflow Since August

Grayscale's U.S.-listed spot Zcash ETF, ticker ZCSH, logged a substantial weekly net outflow of $93.56 million for the week ended Oct. 2 as the underlying token ZEC retreated from late-September highs. This marked the fund's first negative weekly flow since late August and came amid a notable pullback in ZEC price action after an intense rally that sent attention and capital into Zcash-related products.

ETF Flows: Timing and Scale of Redemptions

Daily Redemption Spikes

SoSoValue ETF data indicates redemptions accelerated at the end of September. ZCSH recorded daily net outflows of $30.25 million on Sept. 30 and another $26.93 million on Oct. 2. When combined with smaller withdrawals across other sessions, total weekly net outflows summed to $93.56 million. Prior to this reversal, the fund had accumulated strong inflows during September, with cumulative net inflows reaching roughly $271 million by mid-month.

Assets Under Management and Net Flows

Net assets under management for ZCSH declined to about $751 million after the outflows. Even with the weekly setback, cumulative net inflows since the ETF conversion remain positive at around $212.56 million. It is important to note that ZCSH holds physical ZEC, so the dollar value of the fund can rise or fall with ZEC market price changes independent of creation or redemption activity.

ZEC Price Action: From Parabolic Gains to Pullback

Recent Price Moves

ZEC surged during September, briefly trading above $1,600 after starting the month below $1,000. CoinGecko historical data shows ZEC closing at $1,653.12 on Sept. 26, then pulling back to $1,483.24 on Sept. 28 and to $1,438.21 on Sept. 30. By Oct. 2 ZEC had declined to $1,301.16 and closed Oct. 3 at $1,304.32 — roughly a 21% slide from the Sept. 26 close.

Drivers of the Retracement

The price retreat was likely multi-factorial. On-chain and derivatives metrics signaled de-risking: perpetual futures open interest on OKX dropped from $236.8 million on Sept. 18 to about $165 million on Sept. 28, suggesting traders reduced leveraged positions. Profit-taking after a rapid rally and reduced speculative leverage appear to have exerted downward pressure alongside shifting spot demand.

Did ETF Redemptions Cause the Price Drop?

While ETF redemptions coincided with the price decline, available evidence does not establish a direct causal link that fully explains ZEC's pullback. Because ZCSH holds ZEC, redemptions can increase selling pressure if shares are redeemed and tokens are liquidated into fiat or other assets. However, falling leverage, profit-taking, and general volatility after a dramatic September run-up were occurring concurrently. In short, ETF outflows were one of several factors affecting ZEC price.

Grayscale Actions: Share Split and DCG Investment

Three-for-One Share Split

Grayscale executed a three-for-one forward share split for ZCSH on Sept. 30. Before the split the fund reported 7,989,300 shares outstanding with an NAV of $111.41 per share; post-split the share count rose to 23,967,900 and NAV per share fell to $37.14. The split did not change the economic value of investors’ holdings and ZCSH continued trading on NYSE Arca under the same ticker.

Digital Currency Group's Authorized Participant Transaction

A separate Grayscale filing revealed Digital Currency Group (DCG) acquired roughly $100 million in ZCSH earlier in September. On Sept. 8 DCG took fund shares through an authorized participant or its designee in exchange for 85,705.32563297 ZEC. Grayscale said the shares received by DCG carried no special rights and were economically equivalent to other ZCSH shares.

Why ZCSH Grew Quickly After Launch

ZCSH is the product of Grayscale converting its long-running Zcash Trust into an exchange-listed spot ETF on Aug. 25, providing U.S. investors with easier exposure to ZEC via NYSE Arca without maintaining direct custody of the token. The ease of access combined with ZEC's price momentum drove rapid asset accumulation, pushing ZCSH past $1 billion in AUM at the height of September’s buying pressure.

NU7 Upgrade and the Zcash Roadmap

Testnet Activation and Zebra Release Candidate

Zcash developers are preparing a meaningful protocol upgrade, NU7. On Oct. 2 the Zcash Foundation announced the release candidate Zebra 7.0.0-rc.0, and testnet activation was expected around Oct. 6 at block height 4,465,026. The NU7 upgrade aims to reduce the target block time from 75 seconds to 25 seconds and introduce a Network Sustainability Mechanism that directs part of transaction fees toward future block rewards. The release also includes limits designed to protect shielded transactions from spam.

Timeline and Mainnet Decision

Developers planned a final decision on the mainnet activation height after reviewing testnet results, with a current roadmap targeting Nov. 5 for mainnet activation and an Oct. 20 deadline for finalizing the activation height. Mainnet node operators do not need to update yet; testnet operators were asked to install Zebra 7.0.0-rc.0 ahead of the Oct. 6 activation to participate in NU7 testing.

Outlook: Volatility and Institutional Adoption

The ZCSH outflows underscore the volatile dynamics that can accompany new spot crypto ETFs and concentrated rallies in their underlying tokens. Institutional interest — evidenced by DCG's authorized participant purchase — and product mechanics such as share splits signal sustained institutional engagement. At the same time, the NU7 upgrade and on-chain developments will remain closely watched by traders and ETF investors because protocol changes can influence network utility, transaction throughput, and long-term demand for ZEC.

For market participants, the near-term story will hinge on whether ZEC stabilizes around current levels, whether leveraged positions remain subdued, and how ETF flows evolve as the market digests both the share-split mechanics and upcoming network upgrades. Investors should continue to monitor ETF inflows/outflows, derivatives open interest, and Zcash engineering updates for a clearer view of supply-demand dynamics in the weeks ahead.
