US spot Bitcoin ETFs registered their strongest weekly performance in nearly a decade, with institutional investors pouring $1.92 billion into the products as Bitcoin rallied above $79,000. According to reporting by CoinTelegraph, the inflows mark a significant inflection point after months of mixed investor sentiment.
The surge reflects renewed institutional appetite. Bitcoin climbed more than 20% during the week, jumping from near $63,000 at the week’s open to breach $79,000 by Friday’s close. Spot ether ETFs captured similar momentum, attracting approximately $700 million during the same period, according to ETF analyst Nate Geraci.
Despite the rally, Bitcoin ETFs remain underwater for the year. US spot Bitcoin ETF products have recorded $2.91 billion in net outflows so far in 2026, a headwind that illustrates the volatility institutional capital has faced navigating crypto markets this year.
The Year-to-Date Withdrawal Pattern
The recent inflow surge masks a turbulent first eight months. June delivered the heaviest monthly outflows at $4.51 billion, preceded by $2.43 billion in May withdrawals. Those declines followed Bitcoin’s tumble from October 2025 highs—the cryptocurrency has fallen roughly 38% from its $124,700 peak on October 6.
Yet August has shown recovery. Net inflows of $2.38 billion through the Friday close mark the strongest monthly performance for Bitcoin ETFs in 2026. The shift signals that after months of institutional retrenchment, asset managers are beginning to re-engage with spot Bitcoin products.
BlackRock’s IBIT Leads the Charge
BlackRock’s iShares Bitcoin Trust (IBIT) spearheaded last week’s rally, capturing $1.33 billion across five consecutive trading days. Inflows accelerated as the week progressed—daily flows rose from $160.2 million on Monday to a peak of $503 million on Thursday before moderating to $239.3 million Friday, according to Farside Investors data.
The pattern caught the attention of Bloomberg ETF analyst Eric Balchunas, who flagged what he termed a “classic Flipping the Bird pattern” in IBIT’s daily flows. Market technicians interpret such accumulation patterns as potential bullish reversal signals, though their predictive value in crypto markets remains contested.
The rebound carries weight given institutional positioning. BlackRock’s dominance in Bitcoin ETF flows underscores how the world’s largest asset manager continues to shape retail and professional capital allocation in crypto. IBIT’s performance last week suggests institutions may be viewing the recent price weakness as a buying opportunity rather than a warning sign.
