Bitcoin Spot ETF Inflows Reach $3.8B in Peak Three-Week Run of 2026

US-listed spot Bitcoin exchange-traded funds (ETFs) extended a late-summer demand surge, logging their strongest three-week stretch of 2026. The rebound coincided with Bitcoin trading around the $80,000 level, with weekly inflows accelerating into the week ending Friday.

SoSoValue data shows the funds pulled in $986.9 million during the week ending Friday. That pushed cumulative net inflows over the past three weeks to $3.8 billion. Total net assets across the suite were $101.3 billion on Friday, after rising to $103.3 billion the prior day. Since inception, cumulative net inflows reached $55.6 billion.

Key takeaways

• US spot Bitcoin ETFs attracted $986.9 million in the week ending Friday, lifting three-week net inflows to $3.8 billion.
• Friday’s total net inflow was $174.6 million, down from a much larger Thursday surge of nearly $731 million.
• BlackRock’s IBIT led demand with $117.4 million on Friday, about 67% of that day’s inflows, per Farside Investors.
• Bitcoin ETF momentum is improving versus the prior week, but year-to-date flows remain about $1 billion negative, reflecting lingering uncertainty from earlier 2026 outflows.
• While Bitcoin inflows strengthened, spot Ether and XRP ETF flows fell sharply on a weekly basis.

Three-week rebound highlights a demand shift

The latest inflow sequence represents a significant improvement from earlier in 2026, when spot Bitcoin ETFs experienced heavy outflows. The contrast matters for market participants tracking whether institutional demand is broadening or simply reacting to short-term price moves.

According to SoSoValue, the three-week net inflow total of $3.8 billion is far more consistent than the earlier part of the year. Still, the broader picture remains mixed: year-to-date net flows are reported to be roughly $1 billion negative. That implies the ETF complex is recovering, but not fully reversing the cumulative drain from prior months.

Net asset values also underline the pace of the recovery. Total net assets across the US-listed spot Bitcoin ETFs stood at $101.3 billion on Friday, following a brief bump to $103.3 billion on Thursday.

Friday inflows cool after Thursday’s spike

Demand didn’t maintain Thursday’s intensity. US spot Bitcoin ETFs recorded $174.6 million in net inflows on Friday, according to the reporting in the week’s flow recap. That figure was a sharp drop from the nearly $731 million recorded a day earlier, as referenced by earlier market coverage linked in the source.

Within the broader total, BlackRock’s iShares Bitcoin Trust (IBIT) remained the dominant driver. Farside Investors data cited in the source shows IBIT received $117.4 million on Friday, contributing about 67% of the day’s net inflows.

Elsewhere, Fidelity’s Wise Origin Bitcoin Fund (FBTC) was the only other fund to post net inflows, attracting $57.2 million. All other US spot Bitcoin ETFs recorded no net flows for the day, highlighting how concentrated inflow activity can be even in a strong overall period.

Price action also provides context for the flow pattern. Bitcoin slid from around $81,200 to briefly under $79,000 on Friday. At the time of publication, Bitcoin traded at $79,716, up about 2.6% over the prior seven days, based on CoinGecko data included in the source.

Rotation away from Ether and XRP ETFs

The rebound in Bitcoin ETF inflows came alongside a noticeable weakening in other crypto-asset ETF demand. Compared with the previous week, Bitcoin ETF inflows were up by about 7%, while flows into US spot Ether and XRP ETFs fell by roughly 74% and 83%, respectively, based on SoSoValue figures.

SoSoValue shows spot Ether ETF inflows dropped to $218.4 million from $824.4 million a week earlier. For XRP, inflows declined to $19 million from $110.5 million over the same comparison period.

Despite the weekly pullback, both Ether and XRP ETF products remain net positive for the year. SoSoValue data cited in the source indicates US spot Ether ETFs have recorded about $863 million in net inflows year-to-date, while XRP ETFs have attracted roughly $515 million.

This divergence is a useful signal for investors: even when institutional allocation preferences shift, it often happens unevenly across asset classes rather than uniformly. For traders and allocators, the key is whether the Bitcoin-specific demand trend continues long enough to further erode earlier negative year-to-date positioning.

What to watch next as flows become the focus

With Bitcoin ETF inflows showing resilience after earlier outflows, the next question is whether the complex can sustain inflow momentum beyond this three-week window—especially given Friday’s cooling versus Thursday’s outsized day. Investors should watch for whether IBIT and FBTC continue to concentrate the bulk of inflows, and whether Ether and XRP ETFs remain under pressure or stabilize after their recent weekly declines.
