US Spot Bitcoin ETFs Pull In $527M, Best Day Since Late September

US spot Bitcoin exchange-traded funds recorded $526.7 million in net inflows on Monday, their largest single-day intake since Sept. 22, according to Farside Investors. The move reversed Friday's $82.4 million in net outflows and broke a two-week streak of weekly losses.

The last comparable day came on Sept. 22, when the funds attracted $714.7 million. Monday's figure stands roughly $190 million below that benchmark, but it marks the strongest showing in nearly a month.

Which funds drove the inflows?

BlackRock's iShares Bitcoin Trust (IBIT) took in $665.2 million, a sum exceeding the net total across all US spot Bitcoin ETFs. Two issuers offset much of that demand:

• Fidelity's Wise Origin Bitcoin Fund (FBTC) bled $83.6 million
• Grayscale Bitcoin Trust (GBTC) lost $54.9 million
• All other funds in the category recorded no net flows

The concentration matters for market structure. A single issuer captured more than the category's entire net intake, meaning investor demand on Monday ran almost entirely through BlackRock's vehicle while competitors held ground or ceded assets.

What preceded the rebound?

Monday's reversal followed two consecutive weeks of net weekly outflows. Spot Bitcoin ETFs shed approximately $229 million last week after losing $681 million the week before, per Farside data. On Oct. 7, the funds recorded $483.9 million in outflows, their largest daily withdrawal since June.

Despite Monday's strength, the category remains about $88 million in negative territory for October, according to Farside's daily figures. One strong session has not yet erased the month's accumulated losses.

How did Ether funds perform?

US spot Ether ETFs moved in the opposite direction. They recorded $103.3 million in net outflows on Monday, led by $95.4 million in withdrawals from BlackRock's iShares Ethereum Trust (ETHA).

Ether funds lost roughly $320 million last week, marking their third consecutive week of net withdrawals. The divergence shows capital rotating back into Bitcoin exposure while Ether products continue to shed assets, even within the same issuer's lineup.

What comes next?

The flows bear watching through the remainder of October. Bitcoin ETFs need roughly $88 million in further net inflows just to bring the month back to breakeven, while Ether funds face the test of halting a three-week withdrawal streak when the next weekly figures land.
