US-listed spot Bitcoin and Ethereum exchange-traded funds attracted a combined $1.1 billion in net inflows during the most recent trading week. This performance stands as the most robust weekly result for these vehicles since April, according to the latest figures and data compiled by SoSoValue.
Spot Bitcoin ETFs led the charge, securing approximately $853.5 million across five consecutive sessions of positive flows.
Daily contributions varied, with stronger activity earlier in the week giving way to more moderate gains toward the close.
BlackRock’s iShares Bitcoin Trust (IBIT) dominated the category, accounting for the overwhelming majority of the new capital—more than 80 percent in some tallies—while other providers such as Fidelity also recorded meaningful additions.
Cumulative net inflows into Bitcoin products have now surpassed $52 billion since their launch, with total net assets hovering near $80 billion.
Ethereum-focused spot ETFs contributed the remainder, drawing in roughly $245 million.
This marked their strongest weekly showing since the same period in April and extended a streak of positive weekly flows to five consecutive periods.
BlackRock’s corresponding Ethereum product again captured the bulk of the activity.
The combined result for Bitcoin and Ethereum funds highlights a clear rebound after a quieter stretch of summer trading.
Interestingly, the surge in capital occurred against a backdrop of relatively subdued trading volumes.
Bitcoin ETF turnover declined notably, and Ethereum volumes fell even more sharply.
Analysts have interpreted this pattern as evidence that longer-term institutional allocators are steadily building positions rather than short-term speculative traders driving the activity.
The concentration of inflows into the largest and most established funds further suggests a preference for scale and perceived quality among professional investors.
Market observers have pointed to several potential contributing factors.
Some have linked the timing to heightened attention on self-custody risks following a recent hardware wallet security incident, which may have reinforced the appeal of institutional-grade products for certain holders seeking long-term exposure.
Others note broader improvements in sentiment toward digital assets after periods of weaker flows earlier in the year.
Regardless of the precise catalysts, the data indicates that demand for regulated access to Bitcoin and Ethereum has strengthened meaningfully in the short term.
These products have transformed how traditional investors gain exposure to the two largest cryptocurrencies.
By holding the underlying assets directly and trading on conventional exchanges, they remove many of the operational and custodial hurdles associated with direct ownership.
The latest weekly figures underscore their continued role as a primary conduit for institutional capital entering the space.
While one strong week does not guarantee sustained momentum, the scale of the inflows—especially after months of more muted activity—offers a constructive signal. Investors and market participants will now most likely closely monitor subsequent flow data to determine whether this represents the start of a more durable recovery in demand for crypto ETFs.
