Bitcoin ETF inflows hit $3.8B in strongest three-week stretch of 2026

US spot Bitcoin ETFs recorded their strongest three-week inflow stretch of 2026, attracting nearly $1 billion in net inflows in the week ending Friday, bringing net inflows over the past three weeks to $3.8 billion, according to SoSoValue data cited by Cointelegraph. The funds pulled in $174.6 million on Friday alone, down sharply from nearly $731 million a day earlier. BlackRock's IBIT drew $117.4 million on Friday, about 67% of the day's total, while Fidelity's FBTC attracted $57.2 million, with no other funds recording net flows. Total net assets across the funds stood at $101.3 billion on Friday after briefly rising to $103.3 billion the day before, and cumulative net inflows reached $55.6 billion. The inflows mark a sharp turnaround from heavy outflows earlier in 2026, though year-to-date net flows remain roughly $1 billion negative. Only one source covers this story, so all claims should be treated with appropriate caution.
