US bitcoin ETFs report the largest inflow day since January, worth $730.8 million
Bitcoin spot ETFs recorded a net inflow of $730.8 million on September 3, 2026, their largest single day since January, as the desk's ETF flows board confirmed. Fed Governor Christopher Waller's dovish comments are attributed by analysts as a driver of the capital surge.
US-listed spot Bitcoin ETFs drew $730.8 million on September 3, 2026, their largest single-day inflow since January, according to the desk's ETF flows board. The inflow came as Bitcoin price reclaimed the $80,000 level, per Cointelegraph's reporting.
Fed Governor Christopher Waller's dovish comments are attributed by analysts cited in The Block's reporting as a driver of the capital surge into bitcoin products. The timing and scale of the inflow suggest institutional positioning in response to signals of a potential shift toward looser monetary policy.
The desk's market boards showed Bitcoin at $79,792.03 as of Friday, September 4, down 1.81% in the 24 hours prior. Over the week ending September 4, Bitcoin rose 1.63%, and over the month it rose 22.66%. However, Bitcoin remains 36.0% below its 12-month high of $124,739.81 reached earlier in the year.
Ethereum ETFs also recorded inflow on September 3, pulling in $141.4 million, a fraction of Bitcoin's $730.8 million. The broader crypto market capitalization fell 4.14% in the 24 hours to September 4, despite the prior day's institutional inflow, and Bitcoin dominance held at 59.2%.
Year-to-date, US bitcoin ETFs have accumulated $55,512 million in net inflows. Ethereum ETFs have drawn $13,159 million cumulatively. The September 3 inflow broke a two-day streak of same-direction flows, per the desk's board data, suggesting a shift in institutional positioning after a period of either outflows or muted activity.
The size of the single-day inflow stands out, but the immediate price weakness that followed raises questions about the durability of the rebound. Bitcoin's weakness on September 4 and the broader market decline suggest the capital injection did not establish a sustained bid.
The desk's ETF flows board recorded net inflow of $730.8 million on September 3, 2026, with cumulative year-to-date inflows of $55,512 million across US bitcoin ETFs.
The $730.8 million inflow is the largest in eight months, but Bitcoin fell 1.81% the next day and the crypto market shed 4.14%, which complicates the narrative of a durable institutional reversal. Whether this inflow represents a durable repositioning on rate expectations or a single tactical move becomes clear as ETF flows evolve over the coming weeks.
