Ark and Fidelity redemptions outweigh BlackRock's $69.85 million bitcoin ETF inflow

ARKB's $85.21 million exit ^[6] and FBTC's $74.55 million ^[7], less IBIT's $69.85 million intake ^[8], come to a net outflow of $89.91 million ^[20]. The category as a whole lost $89.90 million ^[1], so every other US spot bitcoin fund, taken together, ended Monday close to flat ^[20]. Ark and Fidelity redeemed about $2.29 for every dollar BlackRock took in ^[24].

Bitcoin.com News presents the split as a trend, writing that recent bitcoin ETF demand "has increasingly favored the largest vehicles, particularly IBIT, while redemptions elsewhere have become more frequent" ^[25]. The outlet did not publish the fund-level figures from earlier sessions behind that statement. Cointelegraph's figures, from SoSoValue, cover the days just before Monday: bitcoin funds took in about $293 million over the two preceding October sessions ^[9].

Set against the price, the flows are small. Bitcoin sits about 32% below its October 2025 record ^[10], and over that year holders have pulled a net $3.6 billion ^[14], or 5.8% of cumulative inflows ^[3]. Monday's outflow equals about 0.08% of the funds' $110.77 billion in net assets ^{[2] [15]} and about 4% of the $2.18 billion in trading value that day ^[16].

The ether funds test whether buyers favor BlackRock or a single BlackRock product. Ether ETFs lost $50.76 million on Monday ^[4], and BlackRock's ETHA, down $31.88 million, and Fidelity's FETH, down $18.88 million ^[11], account for all of it ^[22]. BlackRock had the larger outflow. Measured against the ether funds' $17.69 billion of net assets ^[12], Monday's withdrawal was about 0.29%, roughly three and a half times the bitcoin rate ^[23], and the five-day streak has taken out about 1.2% ^[17].

If IBIT keeps taking money while FBTC and ARKB keep redeeming through the week ^{[8] [6] [7]}, the concentration claim gets a multi-session record behind it. A return to inflows at Fidelity and Ark would make Monday a one-day reversal inside a positive stretch ^[21]. Should IBIT turn negative, the bitcoin funds would start to resemble the ether funds, where BlackRock's product led the exits ^[11].

I think the evidence supports the narrow version: on Monday, buyers chose IBIT, and the preference did not reach BlackRock's ether fund ^{[8] [11]}. A run of sessions in which IBIT and ETHA both take in money while Fidelity's two funds lose it would point to BlackRock itself as the destination and prove that reading wrong ^{[8] [11]}.
