Spot Bitcoin ETFs Close Their Best Week Since April

US spot bitcoin exchange-traded funds took in $853.54 million across the five sessions from 3 to 7 August, their strongest week since April, with no outflow days in the run. BlackRock's IBIT absorbed $693.5 million of that, roughly 81 percent of the total, on the flow data TFTC and coinpaprika compiled. Friday's session added $98.85 million, the smallest of the five daily prints. The week does not undo the year. The funds remain roughly $4.44 billion to $4.5 billion in net redemptions for 2026, and weekly trading volumes fell 9 percent for bitcoin ETFs and 21 percent for ether ETFs.

Monday to Friday: $244.42 million at the peak, $98.85 million at the close

The run began on Monday 3 August with $170.09 million and built through midweek: $211.49 million on Tuesday, $244.42 million on Wednesday, the strongest single session, and $128.69 million on Thursday. Friday's $98.85 million, which edgeX rounded to "approximately $102 million," broke down as IBIT $86.7 million, FBTC $41.0 million, BITB $2.1 million and ARKB $1.9 million, offset by redemptions of $19.4 million from BTCO and $10.6 million from HODL. Spot ether funds added $49.6 million the same day, a fourth consecutive positive session, split between ETHA at $38.1 million and Fidelity's FETH at $11.5 million. The five green sessions followed a $265.4 million redemption on the last session of July.

One week, five different totals

The weekly figure is genuinely contested. The outlets reporting it do not agree. The published totals span $754.69 million to $854.4 million, a gap of about $100 million on the same five days of the same funds:

$853.54 million, the figure at coinpaprika, news.bitcoin.com, CoinDesk and 99bitcoins
$853.5 million at TFTC, the same figure to one decimal place
$854.4 million from Crypto Rover, as quoted by 99bitcoins
$754.69 million from CoinDesk on 7 August, which is the four-day total through Thursday
$784 million from CoinGape on 7 August, which reconciles to nothing on the record

Two of those reconcile cleanly. The $754.69 million figure is the sum of Monday through Thursday, and $853.54 million is that sum plus Friday's $98.85 million. The $854.4 million and $784 million prints do not resolve against the daily series. edgeX declined to give a precise number at all, saying only that the week "exceeded $750 million." The framing disagrees too. news.bitcoin.com called it the strongest week since 17 April, CoinDesk the highest weekly total since mid-April, Cryptonomist the strongest weekly inflow since early May, and CoinGape, writing midweek, the best week since May 2026.

Four dollars in five went to one issuer

IBIT's $693.5 million is exactly the sum of its five daily lines of $111.4 million, $170.3 million, $196.8 million, $128.3 million and $86.7 million, which makes the concentration figure the most solid number in the week. Behind it, FBTC took $116.5 million, ARKB $50.8 million, BITB $25.9 million, MSBT $21.4 million and Grayscale's products $14.3 million between them. The ether side was more concentrated still: about $244.9 million for the week, of which BlackRock accounted for roughly $212 million, or about 87 percent. One caution on the tables in circulation: 99bitcoins published IBIT's weekly total alongside daily figures for the other funds, and one outlet described investors as adding through all five ether sessions when Monday was in fact an outflow of between $11.42 million and $12.3 million depending on the tracker.

A big week, not yet a turn

Liya Kalchev, an analyst at Nexo, said spot bitcoin ETFs had "taken in more than half a billion dollars so far in August…a sharp reversal from June, when the funds recorded their worst month," but added that "the marginal buyer looks more tactical than convicted, and a genuine recovery narrative likely needs a decisive close above $65,000 to take hold." Bitcoin did not close above that level during the week. The intraday high was $65,143.87 on Friday. With net outflows for the year still measured in billions and volumes contracting on both product sets, the test is whether the flows persist into a second week rather than whether the first one was large.
