Bitcoin ETF Spot Institutional Fund Flows: Inflows Are Slowing Down, a Significant Hidden Risk Is Emerging!
Friends, let's first look at the latest ETF institutional fund flow situation (as shown in the figure below):
Yesterday, the US Bitcoin spot ETF had a net inflow of $134 million, marking the 7th consecutive day of net inflows.
However, the amount is continuously declining, which is not a good sign! ETF institutions are no longer aggressively buying BTC.
Let's look at the fund flow rhythm over this week:
September 21, single-day inflow of $999 million, setting the highest record in 2026.
September 22, $715 million.
September 23, $347 million.
September 24, $191 million.
September 25, $134 million.
From $999 million to $134 million, a drop of 87% over five days.
BlackRock IBIT remains the absolute main buyer of BTC among ETF institutions.
On September 25, IBIT had a single-day inflow of $96.99 million, accounting for 72% of the total inflow that day. Fidelity FBTC inflowed $49.32 million; together, these two accounted for almost all inflows.
In the past 7 trading days, IBIT has cumulatively inflowed about $1.35 billion, nearly half of the total inflow in the entire ETF category.
What does this mean?
ETF buying is rapidly slowing down. Monday's $999 million was a pulse inflow driven by short squeeze and FOMO sentiment combined, followed by three consecutive days of decline, indicating that chasing funds are retreating.
The direction hasn't changed; money is still coming in, just less so.
