Bitcoin and Ethereum ETFs Top $1B in Best Week Since April as BlackRock Takes 80%

Bitcoin and Ethereum ETFs pulled in more than $1 billion in combined net inflows over the past week, their strongest showing since April, with BlackRock capturing roughly 80% of the total cash.

The weekly haul across U.S. spot Bitcoin and Ethereum ETFs topped $1.1 billion, marking the best inflow week since April even as trading volumes stayed low. The figure spans both asset classes, tying the rebound to spot ETF products rather than a single fund line. For related coverage, see Spot Bitcoin ETFs Draw Over $170M in Net Inflows on Monday.

• TLDR: Combined Bitcoin and Ethereum ETF inflows crossed $1 billion for the week.
• It was the strongest weekly total since April.
• BlackRock accounted for about 80% of the money that entered the funds.

Why BlackRock captured 80% of the week’s ETF inflows

The most striking detail is concentration: roughly four out of every five dollars that entered these ETFs went through BlackRock’s products, per issuer-level flow data. The bulk of the week’s momentum came from one issuer rather than being spread evenly across the field.

That dominance is what separates this week from a routine inflow report. Heavy tilting toward a single issuer can signal where investors are steering their allocations, and BlackRock has repeatedly drawn outsized interest, including when its clients bought Ethereum through the spot ETF.

The contrast matters. Aggregate ETF strength above the billion-dollar mark looks broad, but the issuer breakdown shows the strength is narrow, resting on demand for one provider’s funds rather than a market-wide rush.

What the breakout week could signal for crypto sentiment

A return to the fastest weekly pace since April points to renewed institutional appetite for both assets. Because the headline covers Bitcoin and Ethereum together, the read-through extends beyond a single token, echoing recent stretches when Ethereum ETF inflows outpaced Bitcoin.

The caveat, noted in the reporting, is that the inflows came despite low trading volume, so the demand is not yet backed by broad market turnover. That mix warrants caution before reading the week as a durable trend.

Readers watching for confirmation should track whether the pace holds in the next weekly flow reports and whether inflows broaden beyond BlackRock. Single-day swings, such as the days when Bitcoin and Ethereum ETFs both logged fresh inflows or when several funds recovered after a large outflow, offer the clearest near-term signal of whether this billion-dollar week extends or fades.
