Summary
Bitcoin ETFs attracted $66.2 million in net inflows, more than double Monday's $31 million. BlackRock's iShares Bitcoin Trust (IBIT) led the charge with $51.1 million, underscoring its dominant market position among institutional Bitcoin exposure vehicles. ARK 21Shares' ARKB contributed an additional $33.2 million, positioning the two largest Bitcoin ETF managers as the primary beneficiaries of Tuesday's demand. These gains were partially offset by $18.1 million in outflows from Bitwise's BITB, while Fidelity's FBTC, Grayscale's GBTC and Bitcoin Mini Trust, Morgan Stanley's MSBT, and other tracked products recorded flat activity.
The positive Bitcoin momentum contrasted sharply with Ether's reversal. Ether ETFs posted $2.8 million in net outflows, halting a six-session winning streak. Solana products added $5.4 million but slowed considerably from Monday's $7.7 million, suggesting some consolidation across smaller-cap digital asset exposure.
The aggregate inflow picture masks a significant deceleration in Bitcoin ETF demand. The category had recorded extraordinary flows the previous week, attracting $999 million on September 21 and $714.7 million on September 22. This momentum deteriorated substantially through the week, declining to $346.9 million on Wednesday, $190.7 million on Thursday, and $134.5 million on Friday. Monday and Tuesday extended the positive streak but at materially lower velocity, indicating potential exhaustion of near-term institutional demand.
Bitcoin itself consolidated in the $83,000–$84,000 range on September 29, reflecting its strong third-quarter performance while facing headwinds from elevated Treasury yields that continued to pressure broader risk assets. This price action aligns with the observed flow deceleration, suggesting that institutional interest may be stabilizing at lower levels after the initial wave of quarterly strength.
