BlackRock’s official fund page shows IBIT holding $44,869,214,850 in net assets as of June 26, 2026. Fidelity’s FBTC, by comparison, reported total net assets of approximately $11.
BlackRock’s iShares Bitcoin Trust ETF (IBIT) has reportedly surpassed Fidelity’s Wise Origin Bitcoin Fund (FBTC) in total net assets, cementing its position as the largest spot bitcoin ETF in the United States.
BlackRock’s official fund page shows IBIT holding $44,869,214,850 in net assets as of June 26, 2026. Fidelity’s FBTC, by comparison, reported total net assets of approximately $11.3 billion as of June 18, 2026, according to its official holdings disclosure.

The gap between the two funds is substantial. IBIT’s assets are roughly four times those of FBTC, reflecting BlackRock’s dominance in the spot bitcoin ETF category since both products launched in January 2024.
How IBIT Built a Commanding Lead
Both IBIT and FBTC entered the market after the SEC approved the listing and trading of spot bitcoin exchange-traded products on January 10, 2024. That regulatory approval of bitcoin-linked exchange-traded products opened the door for traditional asset managers to offer direct bitcoin exposure through familiar brokerage accounts.
IBIT’s fund inception date of January 5, 2024 gave it a slight head start. But the scale of its asset accumulation, reaching nearly $44.9 billion in under two and a half years, reflects BlackRock’s distribution network and brand recognition among institutional allocators.
The asset comparison matters because ETF size influences liquidity, tracking accuracy, and institutional adoption. Larger funds typically offer tighter bid-ask spreads and attract more market-maker participation, which can create a self-reinforcing cycle of inflows. This dynamic has been visible across the broader spot bitcoin ETF market, where flow patterns have varied significantly between issuers.
Bitcoin Market Context
The reported asset milestone comes with bitcoin trading around $59,799, up roughly 0.35% over the prior 24 hours.
The crypto Fear & Greed Index sits at 12, deep in “Extreme Fear” territory. That sentiment reading suggests the ETF asset growth has occurred despite cautious broader market conditions, not because of speculative euphoria.
Competition among spot bitcoin ETF issuers continues to intensify. VanEck has targeted BlackRock directly with fee-competitive offerings, while BlackRock itself has expanded into tokenized fund products beyond its bitcoin ETF.
What Remains Unconfirmed
The word “reportedly” in the headline reflects that while official issuer disclosures confirm the individual asset totals, the exact timing and circumstances of when IBIT first overtook FBTC have not been pinpointed to a specific date.
According to one unconfirmed report, IBIT held 742,870 bitcoin on behalf of investors. That figure has not been independently verified against official BlackRock disclosures in this reporting cycle.
The FBTC asset figure of $11.3 billion dates to June 18, 2026, eight days before the IBIT snapshot. Asset totals fluctuate daily with bitcoin’s price and fund flows, meaning the precise gap between the two products shifts continuously.
