Spot Bitcoin ETFs have recorded over $2.3 billion in net inflows across the last four trading days, signaling a strong reversal from earlier October outflows. Daily inflows accelerated significantly during this period, totaling $160 million, $433 million, $999 million, and $715 million respectively. This sustained buying pressure is rapidly erasing the net outflows that began earlier in October. The recent surge suggests renewed institutional demand and marks a pivotal shift in fund flow momentum for spot Bitcoin products since October 10.
