**BlackRock**'s spot Bitcoin ETF pulled in more than $1 billion in new funds in just four trading days, while Bitcoin (BTC) was consolidating above $87,000.
Key points
BlackRock IBIT saw approximately $1.02 billion in net inflows during September 17–22 (local time)
Over the same period, the entire U.S. spot Bitcoin ETF market attracted $2.31 billion in inflows; of that, about 44% went to IBIT
Bitcoin surged to around $87,283 during the day before retreating to the $84,000s
Bitcoin ETF fund flows
According to data compiled by Farside Investors, after $183.7 million flowed into IBIT on September 17 and $108.4 million on September 18,
on the 21st it increased sharply to $381.4 million, and on the 22nd it rose to $350.3 million.
When you combine these four trading days, the net inflow into IBIT totals about $1.02 billion.
Over the same period, the total inflow into all U.S.-listed spot Bitcoin ETFs was about $2.31 billion, and
IBIT accounted for roughly 44% of that.
This figure does not mean that BlackRock directly bought $1 billion worth of Bitcoin,
but rather how much investor capital has flowed into ETFs.
Thanks to this structure, investors can indirectly invest in Bitcoin without any separate wallet management or custody burden,
using existing brokerage accounts within the regulated framework.

Bitcoin price correction
Fund inflows into ETFs continued alongside the Bitcoin rally, but afterward, Bitcoin gave back part of its gains.
The price, which had risen to around $87,283 during the day, later slid to about $84,175,
with the daily decline at the time recording roughly 2.35%.
It is meaningful that even in the price-sliding range, money continues to flow into ETFs.
This is evidence that even if short-term profit-taking occurs, money does not immediately leave.
However, price direction is not determined by ETF fund flows alone.
Other factors also play a role, such as profit-taking in the spot and futures markets, adjustments to leverage, and changes in positions in other derivatives.
Because other factors operate at the same time.
After this correction, Bitcoin was still identified in technical analysis as a short-term support line,
and it is holding above around $80,000. This zone had acted as a strong resistance until just before,
turning into a support area after the recent rally.
If the $80,000 level breaks downward, the $75,000–$76,000 range where demand previously concentrated
could once again emerge as a key checkpoint.
This rally in net inflows also confirms that Bitcoin ETF demand has been swinging significantly throughout this year.
This is because, depending on changes in market conditions, institutional capital repeatedly shifts directions quickly.
IBIT, too, has seen large-scale redemptions and heavy net inflows alternate across Bitcoin’s upswings and correction phases.
