US spot Bitcoin ETFs brought in $110.3 million in net inflows on Monday, October 26. BlackRock’s iShares Bitcoin Trust (IBIT) took all of it.
Every other fund in the category recorded no net flows for the day.
Monday’s number looks modest next to what IBIT pulled in a week earlier. On October 19, the fund recorded a single-day inflow of $665 million.
Three days after that, the mood reversed. The category posted a net outflow of $635.5 million on October 22, nearly erasing IBIT’s big day in one session.
Put those moves together and the month still leans negative. Bitcoin ETFs logged net outflows of roughly $202 million month-to-date through October 26.
Trading activity stayed healthy despite the whiplash. Volume across the Bitcoin ETF category hit $1.86 billion on October 26.
Volume and flows measure different things, and the gap is worth noting. Volume counts shares changing hands between investors. Net flows track whether new money is actually entering or leaving the funds.
A day with $1.86 billion in trading and only $110.3 million in net creations tells you plenty of investors were swapping positions. Fewer were adding fresh capital.
IBIT’s grip on the category
The broader numbers show just how dominant BlackRock’s fund has become. Total assets under management across all US spot Bitcoin ETFs stood at approximately $102.84 billion as of October 26.
IBIT alone held about $64.8 billion of that. That puts well over half the category’s assets in a single product.
The flow picture is even more lopsided. Since the products launched in January 2024, US spot Bitcoin ETFs have collectively accumulated $57.29 billion in net inflows.
IBIT’s own cumulative inflows sit at $66.24 billion. Yes, one fund’s tally is larger than the entire category’s total.
That only works if the rest of the field, taken together, has bled money over time. IBIT has captured more inflows than all other Bitcoin ETFs combined since its launch.
Shorter-term momentum points the same way. IBIT posted a 30-day net inflow of +$933.1 million, ranking first among spot Bitcoin ETFs.
The background
US spot Bitcoin ETFs debuted in January 2024, giving traditional investors a way to get Bitcoin exposure through an ordinary brokerage account.
Since then, the funds have grown into a meaningful slice of the Bitcoin market. Cumulative net inflows of $57.29 billion amount to approximately 6.41–6.44% of Bitcoin’s market value.
What this means
The more durable story is concentration. When a single fund holds about $64.8 billion of a roughly $102.84 billion category and captures every dollar of net inflow on a given day, its flows effectively become the category’s flows.
For investors tracking ETF data as a sentiment gauge, that changes how to read the reports. A strong IBIT day can mask weakness elsewhere, and a weak IBIT day can drag the whole category into the red.
Traders looking for signals have a few things to watch. The first is whether the October month-to-date deficit of roughly $202 million narrows or widens before month end.
The second is whether other funds start recording inflows again, or whether IBIT keeps operating as the only door new money walks through.
The third is the relationship between trading volume and net flows. A session like Monday, with $1.86 billion traded and $110.3 million in net creations, suggests active repositioning rather than a wholesale rush in.
