US spot Bitcoin ETFs took in $3.08bn over nine consecutive sessions to 29 September, then gave up $148.7m on the 30th. The broken streak is what got reported. The shape of it is more telling.
Daily demand peaked at $999m on 21 September. Five sessions later it was $31m, a fall of 97% while the run was still technically unbroken.
Three quarters arrived in four days
The nine days were not steady accumulation. According to Farside Investors, $2.31bn of the $3.08bn landed in the first four sessions, between 17 and 22 September. That is exactly three quarters of the total. The final three days brought in $232m between them, or 7.5%.
By the time the streak ended, the last two sessions had come in under $70m. The reversal on 30 September was small in absolute terms. What came before it was the demand draining away.
What the funds are up against
The pressure is coming from the bond market. The Federal Reserve raised rates by 25 basis points on 16 September to a range of 3.75% to 4%, its first increase since July 2023, on a unanimous vote. Bloomberg reported the 10-year Treasury yield at its highest since 2007, and it closed the month at 5.29%. The 30-year, at 5.63%, is the highest since 2004.
Bitcoin pays nothing. When a government bond pays over 5% for a decade with no credit risk, an allocation yielding zero has to be argued for rather than assumed. The Fed’s own median projection points to one more increase this year, and the next decision lands on 28 October.
The run was a repair, not a breakout
Scale puts the nine days in proportion. Cumulative net inflows into the funds stand at roughly $57.6bn. They peaked at $62.8bn on 10 October 2025 and fell to about $50.9bn by 13 July 2026, a drawdown of $11.9bn across nine months.
September’s run was part of climbing out of that hole rather than breaking new ground. Even with it banked, the category sits around $5bn below where it stood a year ago.
Bitcoin itself is holding better than its fund flows. It trades at $84,708, up 1.2% on the day and close to flat over the week, though still 32.8% below its peak of $126,080.
