Bitcoin ETF Momentum Extends to Six Sessions as BlackRock Dominates Flows
U.S. spot Bitcoin exchange-traded funds maintained their upward trajectory on September 24, marking the sixth consecutive trading session of positive net capital inflows. According to data compiled by SoSoValue, the cohort of Bitcoin investment products attracted approximately $190.7 million in combined net inflows during the session. The momentum underscores sustained institutional and retail appetite for regulated Bitcoin exposure amid a constructive macro backdrop for digital assets.
BlackRock’s iShares Bitcoin Trust (IBIT) continued to function as the primary conduit for new capital, capturing $162.6 million of the day’s total — representing roughly 85% of aggregate inflows across all spot Bitcoin ETFs. The fund’s dominance reflects its first-mover advantage, deep liquidity profile, and widespread adoption across advisory platforms. Trailing significantly behind, Fidelity’s Wise Origin Bitcoin Fund (FBTC) recorded $12.9 million in net subscriptions, while Morgan Stanley’s Bitcoin Trust (MSBT) added $10.2 million. Franklin Templeton’s Digital Holdings Trust (EZBC) and Bitwise’s Bitcoin ETF (BITB) rounded out the positive contributors with $4.9 million and $4.1 million, respectively.
WisdomTree BTCW Bucks Trend With Modest Outflow
Not every fund participated in the rally. WisdomTree’s Bitcoin Fund (BTCW) registered a net outflow of $4 million, the sole negative print among Bitcoin ETFs on the day. The divergence suggests investors are discriminating based on factors such as expense ratios, custodial arrangements, or distribution reach. Despite the single-fund redemption, the category’s overall net flow remained firmly in positive territory, reinforcing the broader accumulation narrative.
Ether ETFs Build on Momentum With Fifth Straight Day of Inflows
A parallel trend emerged in the spot Ether ETF complex, where net inflows reached approximately $66.1 million on September 24 — extending the positive streak to five consecutive trading sessions. BlackRock’s iShares Ethereum Trust (ETHA) led the category with $26.8 million in net creations, followed closely by Fidelity’s Ethereum Fund (FETH) at $21.5 million. Grayscale’s Mini Ethereum Trust (ETHE), the lower-fee successor to the firm’s legacy Grayscale Ethereum Trust, continued to attract capital with a $17.8 million net inflow, signaling successful migration of assets from its higher-cost predecessor.
The synchronized inflows across both Bitcoin and Ether vehicles indicate broadening demand for diversified crypto exposure within traditional portfolio frameworks. Market participants note that the dual-asset momentum coincides with improved regulatory clarity, evolving institutional custody infrastructure, and growing advisor comfort with digital asset allocations.
Why This Matters
The six-day Bitcoin ETF inflow streak and five-day Ether ETF streak represent the longest sustained periods of simultaneous positive flows since the products launched earlier this year. This consistency suggests the initial post-launch volatility has given way to a more structural demand phase, where allocators treat spot crypto ETFs as core portfolio building blocks rather than tactical trades. BlackRock’s outsized share of flows across both asset classes highlights the asset manager’s distribution advantage and the trust advisors place in its brand. Meanwhile, Grayscale’s Mini ETHE success demonstrates that fee competition can recapture assets even from entrenched incumbents. Going forward, market observers will monitor whether inflows persist during periods of price consolidation or if they remain tightly correlated with bullish price action. The next inflection point may come from options approvals on spot ETFs, which could unlock additional institutional strategies and deepen liquidity.
