BlackRock’s iShares Bitcoin Trust (IBIT) has reportedly overtaken Fidelity’s Wise Origin Bitcoin Fund (FBTC) in total net assets, cementing its status as the dominant spot bitcoin ETF in the United States. As of June 26, 2026, BlackRock’s official fund page listed IBIT’s net assets at $44,869,214,850, while Fidelity disclosed approximately $11.3 billion for FBTC as of June 18, 2026 — a gap of nearly four times. The milestone underscores how quickly bitcoin exposure has been concentrated into a few large issuers since the SEC approved spot bitcoin ETPs in January 2024.
The asset comparison is more than a ranking shift; it reflects the self-reinforcing dynamics of ETF markets. Deeper liquidity, tighter bid-ask spreads, and BlackRock’s vast distribution network have funneled institutional and retail demand into IBIT. Fidelity remains a critical player in digital assets, but BlackRock’s scale has created a feedback loop where the biggest fund continues to attract more flows. While the exact date IBIT surpassed FBTC remains unconfirmed, the numbers signal that bitcoin’s institutional era is increasingly shaped by traditional finance forces like brand trust and liquidity.
The milestone arrives amid cautious market conditions: bitcoin traded around $59,799 with a Crypto Fear & Greed Index of 12 (Extreme Fear). The ETF asset growth occurred despite this sentiment, suggesting a sticky institutional base. However, analysts caution that ETF dominance does not guarantee resilient flows during downturns, and that the ETF wrapper and bitcoin’s price are distinct.
