Bitcoin ETFs record $3.8B inflows in strongest three-week stretch of 2026

Strong weekly inflows continue for Bitcoin funds

US spot Bitcoin exchange-traded funds (ETFs) attracted nearly $1 billion in the latest week, marking the strongest three-week stretch for the funds in 2026. An ETF is a fund that trades on stock exchanges and holds assets like Bitcoin, allowing investors to gain exposure without buying the cryptocurrency directly. According to SoSoValue data, the funds brought in $986.9 million by the end of last Friday. This push brings total net inflows over the past three weeks to $3.8 billion. The surge in demand comes as Bitcoin traded around $80,000, despite briefly dipping below $79,000 on Friday. The recovery follows heavy outflows earlier in the year, though total net flows for 2026 remain slightly negative at roughly $1 billion.

BlackRock leads Friday gains

Friday's inflows cooled compared to the previous day, which saw nearly $731 million enter the market. On Friday, net inflows totaled $174.6 million. BlackRock’s iShares Bitcoin Trust (IBIT), the largest spot Bitcoin ETF by assets under management, drew $117.4 million, accounting for about 67% of the day’s total. Fidelity’s Wise Origin Bitcoin Fund (FBTC) was the only other fund to record net inflows, adding $57.2 million. All other US spot Bitcoin ETFs recorded no net flows for the day, according to Farside Investors data.

Bitcoin flows rise while Ether and XRP lag

Bitcoin ETF inflows increased by about 7% compared to the previous week. In contrast, demand for other major crypto ETFs slowed significantly. Inflows into US spot Ether ETFs fell about 74%, dropping from $824.4 million to $218.4 million. XRP ETF inflows declined roughly 83%, falling from $110.5 million to $19 million. Despite these weekly drops, both Ether and XRP ETFs remain positive for the year. Year-to-date, spot Ether ETFs have recorded about $863 million in net inflows, while XRP ETFs have attracted roughly $515 million.

What is confirmed

- US spot Bitcoin ETFs saw $986.9 million in net inflows for the week ending Friday. - Three-week cumulative inflows reached $3.8 billion, the highest for any three-week period in 2026. - Total net assets across the funds stood at $101.3 billion on Friday. - BlackRock’s IBIT accounted for $117.4 million of Friday’s inflows. - Ether and XRP ETF inflows fell sharply compared to the prior week.

Why it matters

The data highlights a divergence in investor interest within the crypto ETF market. While Bitcoin continues to draw significant institutional and retail capital, interest in alternative crypto ETFs has weakened. This trend underscores Bitcoin's continued dominance in the ETF space despite short-term price volatility.
