Bitcoin ETFs buy $160M on Monday, total assets surpass $100B
I'm LongbridgeAI, I can summarize articles.US spot Bitcoin ETFs recorded $160 million in net inflows on September 14, pushing total assets past $100 billion. BlackRock's IBIT led with $134 million, while Fidelity added $53 million; ARKB saw outflows. This influx ended a four-day outflow streak, indicating short-term positioning rather than structural demand shifts. Since launch, cumulative inflows reached $55.3 billion, with IBIT holding $64.1 billion.
US spot Bitcoin ETFs attracted $160 million in net inflows on Monday, September 14, pushing the category's total net assets past the $100 billion threshold. The buying spree snapped a streak of outflows that had persisted from September 8 through 11.
BlackRock's iShares Bitcoin Trust (IBIT) did most of the heavy lifting, pulling in roughly $134 million of that total. Fidelity's Wise Origin Bitcoin Fund (FBTC) added approximately $53 million. Not every fund joined the party, though: ARK 21Shares' ARKB shed about $42 million on the same day.
This isn't the first time Bitcoin ETFs have crossed the $100 billion mark in 2026. The category has oscillated above and below that line multiple times this year, a product of both price-driven gains and capital flows that can swing hundreds of millions in either direction on any given day.
Since the spot Bitcoin ETFs launched on January 11, 2024, cumulative net inflows have reached approximately $55.3 billion. That figure represents real new capital entering the Bitcoin market through regulated fund wrappers, distinct from the asset appreciation that pushes total holdings higher when prices rise.
Bitcoin was trading between $77,000 and $78,000 around the time of Monday's inflows. For context, the flagship cryptocurrency was hovering near $46,000 when these ETFs first started trading in early 2024.
IBIT's cumulative total now sits at around $64.1 billion, making it far and away the dominant player in the space.
Collectively, spot Bitcoin ETFs hold between 6% and 6.3% of Bitcoin's total supply. That's a meaningful share of an asset with a hard-capped supply of 21 million coins.
Morgan Stanley's MSBT and Franklin Templeton's EZBC also recorded smaller inflows on Monday, though the amounts were modest compared to BlackRock and Fidelity.
The concentration of flows in IBIT raises a notable structural point. BlackRock capturing $134 million out of $160 million in gross inflows means the ETF market is becoming increasingly winner-take-most.
Monday's $160 million inflow followed four consecutive days of outflows from September 8 through 11. The quick reversal suggests the selling was more about short-term positioning than a structural shift in demand.
