Bitcoin & Ethereum ETF Flows: Week Ending August 7, 2026

Disclosure: This article is information and opinion, not financial advice. Flow figures cover the week of August 3 to 7, 2026 and revise as providers reconcile data. See our full disclaimer.

Edition two of ETF Flows Weekly, and the tape did the most useful thing a tape can do: it challenged us.

Bitcoin ETFs just printed five consecutive days of net inflows, Monday through Friday, totaling more than $750 million. Not one down day. For products that bled $5.4 billion in the first half of the year, their first negative half since launch, that’s the strongest week in months by a wide margin.

BlackRock’s IBIT did the heavy lifting, capturing $479 million of one $626 million three-day stretch, and on-chain tracking shows no Bitcoin ETF sold a single coin all August. Fidelity added, and even Franklin Templeton bought for the first time in over a month. The cohort moved together.

And Ethereum? Still positive, suddenly small

ETH funds closed the week with four straight days of inflows, $49.6 million on Friday alone, pushing cumulative inflows since launch past $11 billion, essentially all of it BlackRock’s ETHA. The streak is real and intact.

But zoom out and the proportions inverted. Two weeks ago ETH was taking in double Bitcoin’s money. This week Bitcoin’s haul was several times Ethereum’s. The flow leadership we spent July documenting flipped, hard, in five sessions.

Solana and XRP products, meanwhile, posted literal zeros on multiple days. The two-tier structure of this market keeps confirming itself: BTC and ETH are the institutional doors, everything else is still a hallway.

Grading our own thesis, as promised

Two weeks ago, in the yield repricing thesis, I wrote that falsification would look like “flows flipping back to BTC on the next risk-on week”, and that if it happened, I’d say so in the weekly. It happened. So, per the deal: noted, in public.

Now the honest nuance, because grading isn’t the same as grade-inflation or self-flagellation. The falsification scenario described money leaving ETH for BTC. That’s not quite this week’s shape: ETH didn’t lose flows, Bitcoin found new ones. Both cohorts were positive simultaneously, which reads less like rotation and more like expansion, institutions re-entering risk through the most liquid regulated door first. One flow-desk observation making the rounds put it well: simultaneous BTC and ETH inflows complicate the usual “Bitcoin-first, Ethereum-secondary” narrative in both directions.

So the scorecard, honestly kept: the thesis’s weak version (ETH wins every flow week) is dead, and we said it would be judged in public. The strong version (staking yield unlocked a durable new buyer class for ETH) survives, on evidence that ETH kept attracting money even while Bitcoin dominated the headlines. What died this week was any claim that Bitcoin’s institutional bid was structurally broken. It was hibernating, and $750 million woke it up.

Housekeeping: the windows disagree again

Recurring feature of this series: depending on provider, July’s Bitcoin monthly total reads anywhere from $172 million to $280 million. Same funds, different measurement windows and methodologies, as we covered in edition one. Directions agree, decimals don’t. Treat every precise flow figure, including ours, as a well-sourced approximation.

What to watch this week

Three things. Whether Bitcoin’s streak survives its first red price day, because inflows during stability prove less than inflows during a dip. Whether ETH’s streak extends alongside it, which would confirm the expansion reading over the rotation one. And IBIT concentration, since one issuer supplying most of a $750 million week means one allocator’s pause can end the story as fast as it started.

Bitcoin enters the week recovering toward the mid $60,000s, ETH near $1,916. Both cohorts positive, both streaks alive. The most constructive week the ETF complex has printed since spring, and it gets graded again next Monday.

FAQ

How much did Bitcoin ETFs take in during the first week of August 2026?

More than $750 million in net inflows across five consecutive positive sessions, August 3 through 7, the strongest week in months. BlackRock’s IBIT captured the majority, including $479 million of one three-day stretch, and on-chain tracking showed no Bitcoin ETF selling coins at any point in August.

Did Ethereum ETFs lose money that week?

No. ETH products logged four straight days of inflows including $49.6 million on Friday, pushing cumulative inflows past $11 billion since launch. Bitcoin simply attracted several times more new money, inverting July’s pattern where ETH funds took in roughly double Bitcoin’s flows.

What does it mean when Bitcoin and Ethereum ETFs both see inflows?

Simultaneous inflows suggest expansion rather than rotation: new institutional capital entering crypto through its most liquid regulated products, rather than existing money switching sides. Historically, allocators returning after a risk-off period re-enter through the deepest vehicles first, which favors Bitcoin initially even when demand is broadening.

Which Bitcoin ETF has the most inflows?

BlackRock’s IBIT, and it isn’t close. It captured $479 million of one $626 million three-day stretch this week and has led the category since launching in January 2024. Across all issuers, US spot Bitcoin ETFs have accumulated roughly $52 billion in net inflows with total assets near $79.5 billion.

Why did Bitcoin ETF inflows recover in August 2026?

The likeliest mix: price stability after the July 1 cycle low reduced the fear of catching a falling knife, and institutional allocators deciding the risk-off period had run its course re-entered through the most liquid regulated vehicles first. The contrast is stark: the first half of 2026 saw $5.4 billion leave Bitcoin ETFs, their first negative half-year ever.

Are Solana and XRP ETFs getting inflows?

Barely. Both posted zero-flow days repeatedly during the week, and their assets remain a fraction of the majors’. The market’s two-tier structure keeps confirming itself: BTC and ETH products function as institutional doors, while the newer altcoin ETFs haven’t reached the critical mass needed for consistent daily participation.

Where can I track crypto ETF flows myself?

The two standard dashboards are SoSoValue and Farside Investors, which aggregate daily issuer disclosures, and Arkham’s on-chain tracking shows the ETF wallets’ actual coin movements. Expect small discrepancies between them: different windows and methodologies mean directions agree while precise figures don’t, which is worth remembering whenever a single flow number makes a headline.
