US spot Bitcoin ETFs pulled in $986.9 million over the week ending Friday, September 4. That brings three-week net inflows to $3.8 billion, the strongest stretch these funds have seen all year, according to SoSoValue data.
The inflow streak comes as Bitcoin trades near $80,000. Prices briefly dipped below $79,000 on Friday before recovering. Bitcoin sat at roughly $79,716 at publication time, up about 2.6% over the past week.
Total net assets across all US spot Bitcoin ETFs stood at $101.3 billion on Friday. That figure had briefly touched $103.3 billion a day earlier. Cumulative net inflows since the funds launched now sit at $55.6 billion.
The three-week run stands out against a rough year. Despite the recent buying, year-to-date net flows across Bitcoin ETFs remain about $1 billion negative. Heavy outflows earlier in 2026 had pushed the funds into the red, and this recent demand has only partly closed that gap.
Daily flow data shows the pace slowing toward the end of the week. Thursday brought in nearly $731 million, the highest single-day total since January. Friday's total dropped to $174.6 million, a sharp pullback from the day before.
BlackRock's iShares Bitcoin Trust (IBIT) led Friday's inflows with $117.4 million, about 67% of the day's total. Fidelity's Wise Origin Bitcoin Fund (FBTC) added $57.2 million. Every other US spot Bitcoin ETF recorded zero net flow that day.
Bitcoin ETFs opened 2026 under pressure. The funds had built up strong cumulative inflows since their 2024 launch, but repeated waves of redemptions through the year kept chipping into that base. By late summer, net flows for 2026 had turned negative, a signal that institutional demand had cooled compared to prior years.
The turn began building over the past three weeks as Bitcoin found footing around the $80,000 level after a volatile stretch. Thursday's $731 million single-day inflow was the clearest signal of returning appetite, arriving right as Bitcoin reclaimed $80,000 following a period where the US dollar weakened against the yen amid suspected central bank intervention.
A surprise nonfarm payrolls report later pushed Bitcoin back under $80,000, showing how tied these ETF flows remain to broader macro data. Traders are still reading jobs numbers and dollar strength as directly relevant to Bitcoin positioning, not treating it as a separate asset class yet.
While Bitcoin ETFs gained momentum, Ether and XRP funds cooled fast. Spot Ether ETF inflows fell to $218.4 million from $824.4 million the previous week, a drop of about 74%. XRP ETF inflows fell even harder, down 83% to $19 million from $110.5 million.
The contrast is worth sitting with. Bitcoin ETF inflows rose about 7% week over week while Ether and XRP inflows collapsed. That split suggests investors rotated back toward Bitcoin as a preferred vehicle, at least for this stretch, rather than spreading new capital evenly across crypto ETFs.
Ether and XRP funds still hold positive ground for the year despite the pullback. Spot Ether ETFs have brought in about $863 million in net inflows since January. XRP ETFs have attracted around $515 million over the same period. Both figures are smaller than Bitcoin's asset base by a wide margin, but they show the newer XRP fund category found real demand in its first year trading.
The three-week run gives Bitcoin ETFs their best flow data of 2026, but the setup underneath it is mixed. Assets under management remain far below the pandemic-era highs some analysts expected when spot approval first happened in 2024. Year-to-date flows are still negative, meaning this recent buying is recovery, not fresh net demand beyond where the year began.
The daily breakdown also shows concentration risk. BlackRock's IBIT alone accounted for two-thirds of Friday's inflows, and only one other fund recorded any inflow that day at all. A recovery driven by one or two dominant funds is less stable than broad-based demand spread across the fifteen-plus funds trading in this category.
Bitcoin's price action around $80,000 remains sensitive to macro data outside crypto markets entirely. The nonfarm payrolls surprise that pushed Bitcoin back under $80,000 within days of the inflow report shows that ETF demand and spot price can move in opposite directions quickly. Investors watching this trend should treat the $3.8 billion figure as a real but fragile signal, not proof that 2026's outflow problem is fully behind these funds.
