Record $2.39B Floods Into US Bitcoin ETFs: Is the Bull Run Back?
In a powerful display of renewed institutional interest, US spot Bitcoin exchange-traded funds (ETFs) posted their strongest weekly inflow in years. Last week, these funds collectively saw a net addition of $2.39 billion, marking the highest single-week figure since early 2026.
The Flow Trajectory: A Strong Start Followed by Moderation
The week began with a bang, as nearly $1 billion flowed in on Monday alone. However, the daily pace gradually tapered off, dipping to around $134 million by Friday—a decline of roughly 87% from the week's peak. Crucially, inflows persisted for seven consecutive trading days, underscoring sustained, albeit variable, demand.
Market Volatility Meets Macroeconomic Crosscurrents
The initial surge coincided with sharp moves in the Bitcoin market. Prior to Monday's massive ETF inflows, Bitcoin's price rallied 6.7% on heavy volume. This move triggered a cascade of liquidations, with approximately $262 million in short positions forcibly closed within an hour, adding fuel to the upward momentum.
The landscape shifted mid-week. A S&P Global business survey released on September 23 indicated the US economy was growing at its fastest pace since July 2021. This robust data pushed the yield on the 10-year US Treasury note above the symbolic 5% threshold. In response, Bitcoin faced selling pressure, briefly falling below $84,000 within an hour.
The New Landscape and Path Ahead
Following this active week, the total assets under management (AUM) for US spot Bitcoin ETFs now stand at $108.42 billion. This record-setting influx, occurring against a backdrop of macroeconomic uncertainty and crypto market volatility, signals deepening integration of digital assets into traditional portfolios.
Market observers suggest the consistent net inflows, despite daily fluctuations, point to institutions and long-term capital potentially building positions during periods of price dislocation. The coming weeks will be critical, as investors weigh inflation data, Federal Reserve policy cues, and Bitcoin's own on-chain metrics to gauge whether this inflow trend has staying power.
