WisdomTree Physical Bitcoin AUM Hits $1.45 Billion Amidst Spot ETF Outflows

The assets under management (AUM) of WisdomTree Physical Bitcoin reached $1.45 billion as of September 16, 2026.

This milestone was achieved after Grayscale's GBTC saw net outflows of $43 million on a recent Thursday, while WisdomTree recorded zero net flows on the same day.

The IBIT fund from BlackRock led inflows with $14 million, followed by Bitwise with $7 million. Other funds like Fidelity, Ark Invest, Invesco, Galaxy Digital, and Franklin Templeton logged single-digit net inflows totaling $11 million.

Despite this, the total net outflows for all US spot Bitcoin ETFs on that Thursday totaled $11.29 million, even though most funds except GBTC recorded positive daily net inflows.
