BlackRock’s iShares Bitcoin Trust (IBIT) has officially overtaken SPLG, a long-standing S&P 500 ETF, to become the fourth-largest ETF by year-to-date inflows in 2025. According to Bloomberg analyst Eric Balchunas, this milestone reflects a growing shift in institutional capital allocation—from traditional equities to regulated crypto investment vehicles.
Key Milestones for IBIT
- Net Inflows: $13.75 billion in 2025, slightly surpassing SPLG's $13.74 billion.
- Age: Just 18 months old, yet competing with established passive investment products.

Institutional Adoption of Bitcoin
The rise of IBIT underscores Bitcoin’s legitimization within institutional portfolios. As MicroStrategy Chairman Michael Saylor noted, IBIT could eventually challenge major equity index funds if its trajectory continues.
"Investors are prioritizing access to Bitcoin through regulated, institutionally accepted vehicles," — Eric Balchunas, Bloomberg Analyst.
Broader Market Implications
Despite crypto sector risks, spot Bitcoin ETFs like IBIT are now seen as credible long-term holdings. This shift highlights the convergence of traditional finance and digital assets, with Bitcoin ETFs securing a place among top U.S. investment products.
