Bitcoin and Ethereum ETFs break $1B in their best week since April and BlackRock brought in 80% of the cash
US-listed spot Bitcoin and Ethereum ETFs drew over $1B in fresh inflows in the week ended Aug. 7, according to SoSoValue. Bitcoin ETFs collected $853.54M, with IBIT taking about $693M. Ethereum ETFs added $244.94M, with ETHA taking about $203M. The rebound followed disclosures of the Coldcard hack, though no direct link to ETF flows was shown.
How this was made
The 30-second read
Why it matters
The reported inflow data is a direct, measurable read-through for institutional demand for spot BTC and ETH via regulated vehicles, which can influence short-term price and positioning.
Market read
Weekly spot ETF inflow rebound provides a fresh flow-based catalyst for BTC and ETH, with BlackRock concentration suggesting a clear institutional channel.
What to watch
The article explicitly says there is no evidence the Coldcard breach directly caused ETF inflows, so traders should watch for whether flows fade once the custody narrative cools.
Background
US spot Bitcoin and Ethereum ETFs recorded their strongest weekly inflows since April, with BlackRock’s IBIT and ETHA dominating the totals.
Ticker impact
Spot Bitcoin ETFs pulled in $853.54 million in the week ended Aug. 7, the biggest haul in nearly four months.
Mild to moderate upside bias for BTC over the next several sessions, assuming flows persist.
The article provides concrete weekly inflow totals and notes inflows in every session, which typically supports spot demand expectations even though it does not prove causality from the Coldcard hack.
Ethereum-focused ETFs collected $244.94 million in their strongest week since April, extending a five-week weekly inflow streak.
Potential near-term support for ETH, with follow-through dependent on whether the inflow streak continues.
The text includes session-by-session flow reversals and a multi-week inflow streak, which is actionable for flow-driven positioning, but it lacks direct linkage to any new ETH-specific fundamental catalyst.
Market effects
Stronger spot ETF flows can lift broader crypto sentiment and improve perceived institutional bid for liquid majors.
Primarily US-driven via US-listed spot ETF demand, but can spill over to global crypto markets through price correlation.
Signals to global allocators that regulated access is regaining momentum, potentially affecting cross-venue liquidity and derivatives positioning.
Counterpoint
Inflows may be temporary mean reversion after a custody-related news cycle, not a durable shift in long-term demand.
