The BlackRock Bitcoin ETF, known by its ticker symbol IBIT, has achieved a significant milestone in the world of exchange-traded funds. As of April 23, IBIT has recorded 70 consecutive days of positive investment inflows, securing its place among the top 10 longest-running streaks in ETF history. This remarkable consistency highlights the growing institutional confidence in Bitcoin as a viable and attractive asset class.
Unlike many ETFs that experience fluctuating flows, IBIT has not seen a single day of outflows since its inception. Each day, the fund’s Bitcoin holdings have increased, reflecting sustained investor demand and trust in BlackRock’s execution. This unbroken inflow streak underscores the strength of market sentiment and the increasing integration of digital assets into traditional finance.
The Rise of U.S. Spot Bitcoin ETFs
IBIT’s success is part of a broader trend fueled by the U.S. Securities and Exchange Commission’s (SEC) approval of multiple spot Bitcoin ETFs earlier in 2025. These regulatory green lights have opened the floodgates for institutional and retail investors alike to gain exposure to Bitcoin through regulated, accessible financial products.
Since their launch, U.S.-listed spot Bitcoin ETFs have collectively surpassed $200 billion in total cumulative trading volume. This staggering figure reflects not only the popularity of these funds but also the deep demand for regulated crypto investment vehicles. Among them, BlackRock’s IBIT has emerged as the clear leader, accounting for a substantial share of total inflows.

BlackRock’s Strategic Shift on Bitcoin
Just a few years ago, BlackRock CEO Larry Fink was skeptical about Bitcoin’s long-term viability. Today, the world’s largest asset manager holds over 270,000 bitcoins, valued at more than $18 billion, making it one of the most significant institutional holders of the cryptocurrency.
This dramatic shift in stance from a financial giant like BlackRock signals a pivotal moment in the maturation of Bitcoin as an asset class. Fink has since acknowledged Bitcoin’s role as a potential hedge against inflation and a store of value—narratives once dismissed by traditional finance but now gaining traction at the highest levels.
BlackRock’s entry into the Bitcoin space isn’t just symbolic; it’s strategic. By leveraging its vast distribution network, regulatory expertise, and investor trust, the firm has accelerated mainstream adoption and set a precedent for other asset managers to follow.
Why IBIT’s Inflow Streak Matters
The 70-day inflow streak is more than just a number—it’s a powerful indicator of market confidence, product reliability, and sustained demand. In the ETF world, consistent inflows are often seen as a vote of confidence from both institutional and retail investors.
Eric Balchunas, senior ETF analyst at Bloomberg, highlighted this achievement on social media, noting that “$IBIT inflow streak currently at 69 DAYS. One more day and it moves into Top 10 and ties $JETS.” Reaching this threshold places IBIT alongside long-standing, established ETFs in aviation, technology, and energy sectors—many of which took years to achieve similar momentum.
This milestone also reinforces the idea that Bitcoin is no longer a speculative fringe asset, but a core component of modern portfolios. The fact that a fund like IBIT can attract daily capital without interruption speaks volumes about its structural appeal and market positioning.
Institutional Adoption: A New Era for Bitcoin
The involvement of major financial institutions like BlackRock marks the beginning of a new chapter in Bitcoin’s evolution. When giants like BlackRock allocate billions to Bitcoin, it legitimizes the asset in the eyes of pension funds, endowments, and global investors who previously hesitated due to regulatory or custody concerns.
Moreover, BlackRock’s infrastructure—including custody solutions through partnerships with regulated custodians—addresses key pain points around security and compliance. This reduces friction for traditional investors who want exposure to Bitcoin without managing private keys or navigating exchanges.
As more institutions follow suit, we’re likely to see increased liquidity, tighter bid-ask spreads, and greater price stability in Bitcoin markets—hallmarks of mature financial assets.

Global Implications of U.S. Bitcoin ETF Success
The success of U.S. spot Bitcoin ETFs isn’t just a domestic phenomenon—it has global ripple effects. Regulators in Europe, Asia, and Latin America are closely watching how these products perform in terms of investor protection, market integrity, and capital flows.
Countries that have been cautious about crypto regulation may now reconsider their stance, especially if U.S. ETFs continue to demonstrate resilience and attract trillions in assets over time. The BlackRock effect—where one major player influences an entire industry—could accelerate international adoption and pave the way for similar products abroad.
Additionally, traditional investors who were once skeptical may now view Bitcoin ETFs as a safe on-ramp to digital assets. This could lead to broader portfolio allocations across asset management firms worldwide.
