Catenaa, Sunday, August 30, 2026- US spot bitcoin and ether exchange-traded funds attracted a combined $2.6 billion last week, marking their strongest inflow since October as cryptocurrency prices and ETF trading volumes surged.
Bitcoin ETFs recorded about $1.9 billion in net inflows, while ether funds attracted $697.2 million, according to SoSoValue data analyzed by The Block.
Both categories posted their largest weekly inflows of 2026.
The result represented a sharp reversal from the previous week, when the two groups recorded a combined $392 million in net withdrawals.
That amounts to a week-over-week swing of about $3 billion.
The latest inflows also more than doubled the $1.1 billion combined total recorded during the week ending Aug. 7.
Spot bitcoin ETFs recorded their strongest weekly inflows since the week ending Oct. 10, 2025.
Those funds attracted about $2.7 billion during that earlier period.
Last week’s $1.9 billion lifted cumulative net inflows into US spot bitcoin ETFs to about $53.7 billion since their launch.
The change was also visible in trading activity.
Weekly bitcoin ETF volume reached about $22.1 billion, compared with $6.9 billion during the previous week.
That represents an increase of more than 219%.
The funds’ combined net assets rose to about $96.1 billion from $76.6 billion.
That increase reflects both fresh investor money and bitcoin’s sharp price appreciation during the week.
Much of the strongest buying came during Wednesday and Thursday.
Bitcoin ETFs attracted about $517 million Wednesday, their biggest daily inflow since early May.
Another $606 million entered the products Thursday.
BlackRock’s iShares Bitcoin Trust, or IBIT, accounted for about $503 million of Thursday’s total.
The concentration highlights BlackRock’s continuing influence over US institutional bitcoin demand.
IBIT has become one of the largest vehicles for investors seeking regulated bitcoin exposure without directly holding the cryptocurrency.
Large inflows into the product can therefore have an outsized effect on total ETF demand.
The renewed buying came as bitcoin broke out of a prolonged trading range.
Bitcoin briefly moved above $79,000 Friday during its strongest weekly advance in two years.
The cryptocurrency later traded near $77,200 Saturday.
Ether ETFs also recorded their strongest week since October 2025.
The funds attracted $697.2 million, compared with a $2.3 million net outflow the previous week.
Their cumulative net inflows since launch reached about $12.2 billion.
Weekly trading volume climbed to approximately $6.9 billion from $1.9 billion.
That represents an increase of about 259%.
Combined net assets held by ether ETFs rose to $14.3 billion from $10.5 billion.
That increase was larger than the flow figure alone because ether prices also climbed sharply.
Ether gained more than 20% during the broader market rally and traded near $2,423 Saturday.
ETF asset growth does not come only from investors adding money.
When bitcoin or ether rises, the value of cryptocurrency already held by the funds also increases.
That effect was particularly visible in ether products.
Their combined net assets now exceed cumulative net inflows by about $2.1 billion.
Two weeks earlier, net assets were roughly $711 million below cumulative inflows.
The reversal largely reflects ether’s recent price appreciation.
Bitcoin ETFs experienced the same effect.
Their assets increased about 25% during the week even though the amount of new money entering the products was much smaller than that percentage increase.
The figures suggest institutional and brokerage demand strengthened as crypto prices broke higher.
ETF flows are closely watched because they offer a measure of demand through regulated investment channels.
Unlike direct cryptocurrency purchases, ETFs can be held through conventional brokerage and portfolio-management systems.
That makes them accessible to investors who may not want to manage private keys, cryptocurrency wallets or exchange accounts.
The products are also used by advisers, hedge funds and other professional investors.
A sharp increase in both flows and trading volume therefore suggests more than passive appreciation in existing holdings.
It shows investors were actively trading and adding exposure as prices advanced.
The strong week does not erase the difficult start to 2026.
Bitcoin ETFs remain in net outflow territory for the year.
They have lost about $2.9 billion on a net basis during 2026 despite last week’s surge.
Ether ETFs are also still slightly negative for the year, with approximately $192 million in net outflows.
Before last week’s rebound, the two categories were running a combined year-to-date deficit of about $5.7 billion.
The latest inflows reduced that shortfall to approximately $3.1 billion.
That provides important context for the rally.
The week was exceptionally strong, but investors have not yet reversed all the withdrawals recorded earlier in the year.
Trading volume may be the more immediate signal of changing sentiment.
Bitcoin ETF turnover more than tripled from the previous week.
Ether ETF volume increased by an even larger percentage.
That suggests investors were not simply returning slowly after months of weaker demand.
Activity accelerated rapidly as cryptocurrency prices broke higher.
Higher volume also improves liquidity in ETF shares, making it easier for large investors to enter or exit positions.
If the increase persists, it could strengthen the role of ETFs as a primary bridge between traditional capital markets and crypto assets.
The question now is whether ETF demand continues after the initial price breakout.
Strong inflows can reinforce crypto rallies because ETF issuers must acquire underlying assets to support new shares.
But flows can reverse quickly when prices weaken or investors reduce risk.
The previous week demonstrated that volatility.
A $392 million combined outflow was followed immediately by $2.6 billion in inflows.
The roughly $3 billion swing shows how rapidly institutional sentiment can change.
For bitcoin and ether, the next several weeks will indicate whether last week marked a temporary reaction to rising prices or a broader return of sustained ETF demand.
The current numbers offer the strongest evidence this year that regulated crypto investment products are again drawing large amounts of capital.
The more difficult test is whether that demand survives once the market’s momentum slows.
