BlackRock Leads the Pack
The latest data shows that total net inflows into all Bitcoin spot ETFs for the week reached $2.71 billion. Out of that, BlackRock IBIT alone accounted for the lion’s share. This signals growing investor confidence in the world’s largest asset manager’s Bitcoin product. IBIT total historical net inflow has now climbed to $65.26 billion.
An impressive figure that underscores the fund’s position as the go-to vehicle for institutional Bitcoin exposure. With $93.98 billion in net assets, IBIT now controls roughly 4.13% of Bitcoin total market capitalization. Despite a minor 0.09% discount to its net asset value and a 3.7% daily price drop, trading volume remained robust. The ETF saw $7.02 billion in value traded across 105 million shares. This reflects continued demand even during short-term market corrections.
Market Sees Mixed Flows
While IBIT soared, several other major Bitcoin ETFs saw outflows. Fidelity FBTC recorded a $10.18 million outflow, and Grayscale GBTC saw a larger $19.21 million withdrawal. This continues its months-long streak of redemptions since converting from a trust to an ETF. Meanwhile, smaller players like Ark 21Shares (ARKB) and Grayscale BTC fund also reported modest outflows of around $5-6 million each.
Overall, the total cumulative net inflow across all Bitcoin ETFs stood at $62.77 billion as of October 10. Despite a $4.5 million net outflow on the day, the market maintained a strong position, with total ETF assets reaching nearly $159 billion. This is equivalent to 7% of Bitcoin’s total market cap.
Institutional Confidence Remains High
The surge in IBIT inflows comes as Bitcoin continues to face short-term volatility. But strong long-term optimism. Institutional investors appear to be doubling down on spot ETFs. As a regulated and liquid way to gain Bitcoin exposure without handling the asset directly. BlackRock consistent inflow streak since the ETF’s launch highlights this shift. With its low 0.25% management fee, deep liquidity and brand reputation. IBIT has become the preferred choice for traditional finance players entering crypto markets. Analysts believe that the strong ETF demand could help stabilize the Bitcoin price in the coming weeks. As large inflows often reduce selling pressure.
ETF Race Heats Up
While BlackRock dominates, competitors like Fidelity, Ark 21Shares, and Grayscale continue to adjust their strategies to attract inflows. Fidelity FBTC still holds $24.19 billion in assets. This makes it the second-largest Bitcoin ETF, though far behind IBIT’s scale. The ETF race reflects a broader trend: traditional finance firms are now competing for a share of the crypto market, using ETFs as their main bridge.
As more capital flows in, Bitcoin institutional narrative grows stronger. It is setting the stage for another potential leg up in adoption. BlackRock lead in this race not only shows investor trust. But also signals how deeply Bitcoin has entered mainstream finance. The line between Wall Street and crypto keeps fading and IBIT is at the front of that evolution.
