U.S. Spot Bitcoin And Ether ETFs See $282 Million Weekly Inflows After Eight Weeks Of Outflows

The rebound marks the first positive week since early May, but inflows remain small relative to recent redemptions.

U.S. spot Bitcoin and Ether exchange-traded funds returned to weekly net inflows for the first time since early May, drawing a combined $281.8 million over the five trading sessions ended Friday, according to a Portal do Bitcoin report citing SoSoValue data. The move ended an eight-week stretch of redemptions across the products, though the recovery remained modest compared with the scale of recent outflows.

Bitcoin ETFs Led the Weekly Rebound

Spot Bitcoin ETFs accounted for most of the week’s recovery, with $197.4 million in net inflows. The positive week broke an eight-week run of net withdrawals during which the funds lost about $8.26 billion, according to the cited data.

The report described that sequence as the longest negative streak since U.S. spot Bitcoin ETFs began trading in January 2024. The prior positive week had been the period ended May 8, when Bitcoin funds attracted $622.7 million.

The latest weekly inflow represented only a small offset to the prior drawdown. Based on the figures cited in the report, the $197.4 million added last week amounted to about 2.4% of the $8.26 billion that exited during the preceding eight-week outflow period.

The week’s flow pattern was uneven. Bitcoin ETFs opened with $265.69 million in net inflows on Monday and added another $21.44 million on Tuesday. Those gains were partly reversed across Wednesday and Thursday, when investors withdrew a combined $180.16 million. Net inflows returned on Friday, totaling $90.44 million.

Friday’s Bitcoin ETF demand was concentrated in two products. BlackRock’s iShares Bitcoin Trust recorded $86.83 million in inflows, while VanEck’s HODL took in $3.61 million. The remaining spot Bitcoin ETFs posted no net flow for the day, according to the report.

Ether Products Also Ended an Eight-Week Slide

Spot Ether ETFs also moved back into positive weekly territory, adding $84.4 million in net inflows. The products had not recorded a positive week since the period ended May 8 and had lost approximately $1.20 billion during the eight-week outflow stretch.

The distinction matters for investors tracking crypto ETF demand. Bitcoin ETFs hold exposure to Bitcoin, while Ether ETFs provide exposure to Ether, the native asset of the Ethereum network. ETF flows reflect demand for the regulated fund products themselves and should not be treated as automatic evidence of broader Ethereum network adoption or direct demand for Ethereum-based applications.

The return to inflows suggests that selling pressure through the ETF channel eased during the week. However, the data does not show a broad-based acceleration across every fund. For Bitcoin ETFs, the final trading day’s positive flow was heavily concentrated in BlackRock’s and VanEck’s products, while the rest of the group was flat on a net basis.

Why the Flow Shift Matters for Crypto Markets

ETF flows are closely watched because they offer a transparent, daily read on regulated investor access to Bitcoin and Ether. Positive flows can indicate renewed interest from financial advisers, asset managers, and institutional accounts using ETF structures, while persistent outflows may signal risk reduction, profit-taking, or allocation changes.

The latest data points to stabilization after nearly two months of redemptions, but not yet a full recovery. The combined $281.8 million inflow across Bitcoin and Ether products was significantly smaller than the multibillion-dollar amount withdrawn during the prior losing streak.

For Bitcoin, the comparison is especially stark. The funds added less than $200 million last week after losing more than $8 billion over the previous eight weeks. That means the latest flow reversal may be better understood as an interruption in the outflow trend rather than definitive evidence of sustained institutional accumulation.

For Ether funds, the $84.4 million inflow was also positive but limited relative to the reported $1.20 billion in recent redemptions. Using the cited figures, last week’s inflow offset roughly 7% of the prior eight-week outflow total.

Background on the ETF Flow Cycle

U.S. spot Bitcoin ETFs began trading in January 2024, creating a regulated exchange-traded wrapper for investors seeking Bitcoin exposure without directly holding BTC. Spot Ether ETFs later expanded the ETF market’s coverage to Ether exposure.

Unlike futures-based ETFs, spot ETFs are designed to track the underlying asset more directly by holding the asset or related spot exposure through the fund structure. That distinction is important because spot ETF flows are often interpreted as a closer proxy for demand for the underlying crypto asset than futures ETF activity, though flows still reflect fund-level investor behavior rather than direct blockchain usage.

The eight-week outflow streak that ended last week followed a prior period of stronger demand. According to the report, the last positive week for both Bitcoin and Ether ETFs came in the week ended May 8. Since then, both asset groups experienced sustained withdrawals before the latest rebound.

Risks and Uncertainties Around the Rebound

The flow improvement comes with several caveats. First, the source data was reported through a third-party market data provider and cited by a financial news outlet, rather than an official regulator filing or issuer statement. ETF flow estimates can vary across data providers depending on methodology, timing, and treatment of late adjustments.

Second, one week of net inflows does not confirm a durable trend. The intraweek pattern showed that demand was not consistent across all five sessions, and Bitcoin ETFs still recorded withdrawals across the middle of the week. A more sustained recovery would require additional positive flow periods and broader participation across products.

Third, ETF flows are only one measure of market activity. They do not capture direct spot-market purchases, derivatives positioning, on-chain transfers, staking activity, mining economics, or corporate treasury decisions. They also do not establish whether institutional investors are increasing long-term allocations or making shorter-term tactical adjustments.

Macro conditions, crypto price volatility, regulatory developments, and issuer-level competition could all influence future flows. Investors should also distinguish between inflows into ETF vehicles and any claim about guaranteed price direction. The data confirms a weekly flow reversal, not a guaranteed improvement in asset prices.

Flow Data Points to Relief, Not a Full Reset

The latest week gave Bitcoin and Ether ETF issuers a break from sustained redemptions and showed that regulated crypto products can still attract capital after a prolonged outflow period. The strongest signal came from Bitcoin ETFs, particularly BlackRock’s iShares Bitcoin Trust on Friday, while Ether funds also returned to positive territory.

Still, the scale of the rebound remains limited against the recent withdrawals. The next several weeks of flow data will be important in determining whether the market is seeing renewed allocation demand or merely a short-term pause after an extended period of selling through ETF products.
