US spot Bitcoin exchange-traded funds recorded their strongest week of inflows this year, drawing $2.39 billion in net inflows after adding $134.5 million on Friday, according to data from SoSoValue.

The weekly total marks the largest since the week ending Oct. 10, 2025, when net inflows reached $2.71 billion. It also surpasses the previous 2026 high of $1.92 billion, set in August.

The inflows mark a sharp reversal in the funds' annual trajectory. Year-to-date flows climbed to roughly $926 million as of Friday, recovering from a deficit that stood near $5.55 billion in early July. For the first half of the year, the products had bled assets; the past several weeks have put them back into positive territory on a net basis.

Momentum slowed as the week progressed. Daily net inflows peaked at nearly $1 billion on Monday before tapering through Friday, a deceleration that coincided with Bitcoin retreating from above $87,100. The asset traded near $83,116 at the time of publication, down 1.6% over the past 24 hours but still up 1.7% over the past seven days, according to CoinGecko.

Sentiment indicators remained firmly risk-on. The Crypto Fear & Greed Index, compiled by Alternative.me, stood at 74, up from 70 a week earlier and still within "Greed" territory.

Allocations were not confined to Bitcoin products. US spot Ether ETFs attracted approximately $690 million in net inflows last week, reversing roughly $140 million in outflows recorded the previous week. Spot XRP ETFs added about $76 million over the same period, according to SoSoValue.

The breadth across Bitcoin, Ether and XRP products suggests the renewed demand reflects broader portfolio allocation into regulated crypto vehicles rather than a single-asset trade. Ether funds flipping from outflows to nearly $700 million in weekly inflows represents the sharpest week-over-week swing among the three categories.

For issuers including BlackRock, Fidelity and Bitwise, the sustained inflow streak restores the asset-gathering narrative that defined the products through 2024 and 2025 but stalled during this year's first-half drawdown. Year-to-date figures turning positive also removes a lingering talking point for critics who had pointed to the $5.55 billion deficit as evidence of structural demand fatigue.

The test ahead is durability. Friday's $134.5 million daily figure, while positive, is a fraction of Monday's near-$1 billion peak, and Bitcoin's pullback from above $87,100 has historically coincided with decelerating creation flows. Whether weekly inflows hold above the $1 billion mark in the coming sessions will indicate whether this week marks the start of a sustained reaccumulation phase or a one-off repricing of positioning.
