Summary
U.S. spot bitcoin ETFs experienced their strongest weekly inflow period since mid-April, attracting $853.54 million across five consecutive trading sessions during the first week of August 2026. This performance represents a decisive reversal from the prior week, when the same vehicle class posted $61.53 million in net outflows and terminated a three-week inflow streak. The resurgence underscores renewed institutional appetite for regulated cryptocurrency exposure.
BlackRock's IBIT bitcoin ETF served as the primary driver of this recovery, capturing $693.5 million of the weekly total—representing more than 80% of all inflows. Fidelity's FBTC contributed the second-largest share at $116.5 million, while ARK 21Shares' ARKB added $50.8 million. Smaller allocations flowed into Bitwise's BITB ($25.9 million) and Morgan Stanley's MSBT ($21.4 million). Grayscale's GBTC and Bitcoin Mini Trust recorded nominal inflows of $7.5 million and $6.8 million, respectively. This distribution reflects institutional preference for products from established asset managers with significant market share.
Daily inflow patterns demonstrated consistent accumulation throughout the week. Monday opened with $170.09 million, followed by Tuesday's $211.49 million. Wednesday posted the week's peak at $244.42 million, with momentum sustaining through Thursday ($128.69 million) and Friday ($98.85 million). The uninterrupted five-day positive flow contrasts sharply with recent volatility in the sector. Notably, two products recorded outflows: Vaneck's HODL shed $53.6 million and Invesco's BTCO posted a $12.7 million withdrawal, yet these redemptions proved insufficient to dampen overall market momentum.
Beyond bitcoin vehicles, ether ETFs captured approximately $245 million in inflows during the identical period, while emerging digital assets including XRP, Solana, and HYPE ETFs also posted net gains. This broadening of inflows across multiple asset classes within the ETF ecosystem signals expanding institutional confidence in crypto-linked securities more broadly, rather than concentration in bitcoin alone. The week's performance represents a meaningful institutional re-entry into regulated cryptocurrency products following a period of reduced activity.
