According to SoSoValue, U.S. spot Bitcoin ETFs extended their positive run to four straight weeks, adding nearly $2 billion overall as BlackRock’s IBIT accounted for about $1.7 billion of that total.
The claim is precisely corroborated by reports from PANews and TechFlowPost, which cite SoSoValue data for the specific trading week of March 16–20, 2026. The details regarding BlackRock's IBIT ($191M inflow) and Fidelity's FBTC ($50.07M outflow) match the source data exactly. A slight variation in the total figure ($93.1M) reported by BlockBeats is attributed to a different data aggregator (Farside), which is standard in crypto market reporting.
U.S. spot Bitcoin ETFs recorded $95.18 million in net inflows for the March 16 to March 20 trading week, extending their streak of positive weekly flows to four consecutive weeks. According to SoSoValue, the category has attracted nearly $2 billion over that four-week period, with BlackRock’s IBIT contributing about $1.7 billion of the total. Previously reported weekly fund-level data showed IBIT led inflows during the week, while Fidelity’s FBTC recorded the largest outflows. Total net assets across U.S. spot Bitcoin ETFs stood at $90.30 billion by the end of the reported period.
