US spot Bitcoin ETFs just pulled in over $600 million in a single day, the kind of number that makes you wonder whether Wall Street has quietly decided Bitcoin is just another line item in a balanced portfolio.
The massive daily haul, recorded on August 20, marked the highest single-day net inflow since May 1. And it wasn’t a one-off burst of enthusiasm. It capped a four-day streak of positive flows totaling roughly $1.61 billion, pushing August’s month-to-date inflows past the $2 billion mark.
BlackRock running the table
If you’re guessing which fund led the charge, the answer is the same one it almost always is. BlackRock’s iShares Bitcoin Trust, ticker IBIT, vacuumed up approximately $503 million of the day’s inflows. That’s about 83% of the total, a dominance level that would make most competitors quietly rethink their marketing budgets.
Fidelity’s FBTC came in a distant second with around $65 million in net inflows. Bitwise’s BITB added roughly $26 million. ARK/21Shares’ ARKB managed a minor uptick, while VanEck’s HODL actually saw slight outflows.
The bigger picture in numbers
Since US spot Bitcoin ETFs launched on January 11, 2024, cumulative net inflows have reached approximately $53.4 billion. Total assets under management across the 12 approved Bitcoin funds now sit near $90.2 billion.
Bitcoin’s price hovered around $75,500 during this latest wave of buying. The relationship between ETF inflows and price is a feedback loop worth watching: large inflows require fund issuers to purchase actual Bitcoin on the open market through a creation mechanism, which puts upward pressure on spot prices, which in turn attracts more capital from investors chasing momentum.
Daily fund activity, including creations and redemptions, is tracked by platforms like SoSoValue, Farside Investors, and TFTC, which have become essential dashboards for anyone trying to gauge institutional sentiment in real time.
