US spot Bitcoin ETFs log $1.92B weekly inflows, strongest since Oct 2025

US spot Bitcoin exchange-traded funds recorded their strongest weekly inflows in nearly 10 months as Bitcoin rallied sharply over the same period. SoSoValue data shows net inflows of $1.92 billion for the week ending Friday, the best weekly tally since early 2026. The pickup appeared broad across crypto ETFs. ETF analyst Nate Geraci said Sunday that spot Ether ETFs brought in about $700 million, with both Bitcoin and Ether funds posting their biggest weekly inflows since October 2025. Bitcoin jumped more than 20% on the week, rising from roughly $63,000 to briefly top $79,000 on Friday, according to CoinGecko. Despite the surge, US spot Bitcoin ETFs remain negative for 2026, with year-to-date net outflows of about $2.91 billion. BlackRock's iShares Bitcoin Trust (IBIT) led last week's rebound. Farside Investors data shows IBIT attracted around $1.33 billion in net inflows over five straight trading days. Daily inflows increased from $160.2 million on Monday to $503 million on Thursday before easing to $239.3 million on Friday. Bloomberg ETF analyst Eric Balchunas described the sequence as a "classic Flipping the Bird pattern" and framed it as a bullish signal. Recent inflows follow months of uneven demand. The report notes that June saw the heaviest monthly outflows of 2026 at $4.51 billion after $2.43 billion of withdrawals in May. August has turned supportive, with $2.38 billion in net inflows through Friday, the strongest inflow month of 2026 so far. The piece also points back to the prior major inflow wave in October 2025, when ETFs drew $3.42 billion. It links that period to the Oct. 10 crypto market crash, which it says triggered the largest liquidation event in industry history, wiping out about $19 billion in leveraged positions in 24 hours. Since Oct. 6, when Bitcoin traded near $124,700, the report says the asset is down roughly 38%. Market watchers are now focused on whether August inflows can persist. A single strong week can occur within a broader downtrend, so sustained monthly inflows and broader participation beyond a handful of products will be key signals of whether ETF demand is regaining durability.
