ETH ETFs surge $713M as Bitcoin holds $884M inflow
Bitcoin (BTC)

Cryptobriefing.com reports that Ethereum spot ETFs recorded their strongest weekly inflows in ten months, pulling in $713 million. This figure nearly matches the $884 million that flowed into Bitcoin ETFs during the same period. The combined inflows rank among the largest for any single week since October 2025.
BlackRock’s iShares Ethereum Trust, ticker ETHA, led the charge by absorbing over $122 million in a single day in mid-August. BlackRock’s Bitcoin counterpart, IBIT, similarly dominated BTC flows across multiple sessions. Trading volumes for both products more than tripled compared to prior periods during this peak week.
Cumulative assets under management for BTC ETFs now sit between $96 billion and $100 billion. ETH ETFs currently hold between $13 billion and $15 billion in total AUM. Two macro forces are driving this shift: falling Treasury yields and an improved regulatory backdrop. Fund managers describe this reversal from earlier outflows as a genuine shift in sentiment rather than a tactical bounce.
How the market reacted
Whalio's own Binance spot order flow for BTC, measured when this story was written up on 28 August 2026. Not the outlet's figures.
Bitcoin is trading at $80,249.58 with a 24-hour buy ratio of 45.2%, indicating a slight bearish lean compared to the neutral 50% mark. The 1-hour buy ratio of 43.1% and the 4-hour buy ratio of 47.7% suggest that short-term buying pressure is fading relative to the daily average. Volume delta data reinforces this trend, showing a net outflow of $123,102,218 over the last day, with negative deltas of -$4,402,810 and -$7,192,899 for the 1-hour and 4-hour periods respectively. The Cumulative Volume Delta (CVD) closed at -$97,886,034, confirming that sellers have been more aggressive than buyers over the full 24-hour cycle. Net buying occurred for only 9 out of the 24 hours, highlighting a day where selling pressure dominated the majority of the trading session.
The latest daily buy ratio of 46.7% sits at the 18th percentile of the last 322 days, against a median of 49.2% - weaker buying than most days.
Twenty-four hours later
What BTC did over the 24 hours after the story broke. The market moves for its own reasons; this is what happened, not what the story caused.
Was that an ordinary day?
The same Binance spot measurements for BTC, averaged over the days leading up to the story.
Over the preceding week, the average buy ratio was 51.1%, meaning the current 24-hour ratio of 45.2% represents a notable decline in buying interest. Volume over the last day was only 0.65 times the weekly average, indicating significantly lower participation than usual. While the previous eight days saw a total volume delta of +$171,556,665 and a price increase of 9.9%, today’s negative delta of -$123,102,218 marks a sharp reversal from that momentum. This is an unusual day for the coin, characterized by a drop in both volume and buy ratio compared to the strong weekly trends. The shift from net buying to net selling suggests a cooling off period after the recent price surge.
