AUG 16, 2025 — BlackRock’s iShares Ethereum Trust ETF (ETHA) recorded a $338.1 million net inflow on Aug. 15, 2025, even as the broader cohort of U.S. spot Ether ETFs posted a modest daily net outflow of $59.3 million, according to Farside Investors’ flow tracker.
By the numbers (Aug. 15, 2025)
- ETHA (BlackRock): +$338.1M net flow, topping the day’s leaderboard.
- FETH (Fidelity): -$272.2M; ETHW (Bitwise): -$15.8M; CETH (Invesco/Galaxy): -$4.4M; other funds were flat, producing a total net: -$59.3M for spot ETH ETFs.
- A separate summary from Cointelegraph also flagged the $59.3M daily net outflow, corroborating Farside’s dataset.
How much ETH is that?
Using Ethereum’s Aug. 15 average/close price of roughly $4,44x (varies by data provider), BlackRock’s $338.1M intake equates to about 76,000–76,500 ETH added to ETHA’s basket that day (est. ≈76.1k ETH at ~$4,440).
Market context: whales are active
On-chain and marketj coverage throughout August point to large holders adding exposure despite bouts of volatility. Cointelegraph reported fresh $1.3B whale purchases across multiple new wallets this week, while separate analysis highlighted whales “scooping” ETH from skeptical sellers as price probed multi-year highs.
Why it matters
- Institutional bid resilience: Even on a session with net outflows across the category, ETHA attracted sizable capital, underscoring its role as the default vehicle for many institutions.
- Liquidity & price transmission: Persistent ETF inflows/outflows have been a key driver of ETH’s liquidity profile and intraday moves in recent weeks, as documented by multiple market roundups.
- Accumulation backdrop: Reports of ongoing whale accumulation align with ETF demand and may cushion drawdowns while magnifying upside moves during risk-on sessions.
Summary:
Yes — the claim checks out. On Aug. 15, BlackRock’s ETHA saw $338.1M in net inflows (≈76k ETH at that day’s price), even as the overall U.S. spot ETH ETF set logged a smallj net outflow. Parallel on-chain and media reporting indicates whales are continuing to accumulate ETH into dips and consolidation.
