Bitcoin ETFs Top $100 Billion as $160M Floods In

The Bitcoin ETF market saw significant inflows on Monday, September 14, as spot Bitcoin ETFs attracted $160 million in net inflows. This brought the category's total net assets past the $100 billion threshold.

BlackRock's iShares Bitcoin Trust (IBIT) was the biggest contributor to this buying spree, pulling in roughly $134 million of that total. Fidelity's Wise Origin Bitcoin Fund (FBTC) added approximately $53 million. However, not all funds joined the party: ARK 21Shares' ARKB shed about $42 million on the same day.

This is not 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, due to both price-driven gains and capital flows that can swing hundreds of millions in either direction on any given day.
