BlackRock’s iShares Bitcoin Trust (IBIT), the firm’s flagship spot Bitcoin exchange-traded fund (ETF), has achieved a remarkable milestone by generating nearly $245 million in annual revenue from management fees, making it the most profitable ETF in BlackRock’s portfolio. This figure, based on current assets under management (AUM) and a 0.25% fee structure, surpasses established funds like the iShares Russell 1000 Growth ETF (IWF) and iShares MSCI EAFE ETF (EFA), both earning around $219 million annually despite decades of operation. For investors, crypto analysts, and ETF enthusiasts searching BlackRock IBIT $245 million revenue, most profitable Bitcoin ETF, or IBIT AUM milestone 2025, Bloomberg ETF analyst Eric Balchunas highlighted this “absurd” achievement on October 6, 2025, via X, noting IBIT’s rapid ascent just 22 months after its January 2024 launch. With AUM nearing $100 billion—a record pace faster than Vanguard’s VOO—IBIT’s success underscores Bitcoin’s mainstream adoption, driven by $62.6 billion in cumulative inflows and BTC’s rally above $120,000.
IBIT’s revenue model—0.25% on AUM—has scaled with investor demand and Bitcoin’s price appreciation, positioning BlackRock as a crypto powerhouse amid a $74 billion ETF inflow surge in 2025.
IBIT’s Revenue Milestone: Outpacing Decades-Old ETFs
IBIT’s $244.5 million annualized revenue eclipses BlackRock’s top legacy products, with Balchunas emphasizing the fund’s age disparity: IBIT is just 22 months old, while IWF and EFA have operated for 25 and 24 years, respectively. The iShares Core S&P 500 ETF (IVV) ranks fourth at $210 million, and the iShares Gold Trust (IAU) fifth at $151 million.
- AUM Trajectory: $97.8 billion as of October 6, 2025—$2.2 billion from $100 billion, on track to set the fastest record (vs. VOO’s 2,011 days).
- Inflow Record: $969.95 million on October 6 alone, part of $1.19 billion daily ETF inflows—the largest in 2025.
- Weekly Surge: Bitcoin ETFs drew $3.2 billion last week, with IBIT capturing $1.78 billion.
Balchunas tweeted: “$IBIT a hair away from $100 billion, is now the most profitable ETF for BlackRock by a good amount now based on current AUM. Check out the ages of the rest of the Top 10. Absurd.”
| ETF | Annual Revenue ($M) | Age (Years) | AUM ($B) |
|---|---|---|---|
| IBIT (Bitcoin) | 244.5 | 1.8 | 97.8 |
| IWF (Russell 1000 Growth) | 219.3 | 25 | N/A |
| EFA (MSCI EAFE) | 219 | 24 | N/A |
| IVV (Core S&P 500) | 210 | 25 | N/A |
| IAU (Gold Trust) | 151 | 20 | N/A |
Strategic Context: BlackRock’s Crypto Dominance
IBIT’s profitability reflects BlackRock’s pivot to digital assets, with total crypto inflows at $14.1 billion in Q2 2025 alone. The firm holds 756,000 BTC ($85.29 billion) and 3.8 million ETH ($16 billion), making it the largest institutional custodian.
- ETF Expansion: BlackRock’s Ethereum ETF (ETHA) saw $512 million inflows last week; a Bitcoin premium income ETF filing targets Delaware trust status.
- Market Momentum: Bitcoin’s 9% weekly gain to $120,000, amid ‘Uptober’ hype, has fueled $3.3 billion in Bitcoin ETF inflows last week.
- Institutional Shift: Harvard’s 1.9 million IBIT shares and $3.9 billion Strategy Q3 Bitcoin gains highlight adoption.
BlackRock’s revenue from IBIT—0.25% fee—scales with AUM and BTC price, outpacing zero-fee S&P 500 funds like IVV.
Implications: A New Era for Crypto ETFs
IBIT’s milestone signals:
- Profit Center: Crypto now 1% of BlackRock’s AUM but a key revenue driver.
- Adoption Acceleration: $74 billion ETF inflows in 2025 validate Bitcoin as “digital gold.”
- Competition: Pressures rivals like Fidelity and Grayscale to innovate.
Conclusion: IBIT’s $245 Million Crown
BlackRock’s IBIT Bitcoin ETF $245 million profit cements its status as the firm’s top earner, nearing $100 billion AUM in record time. As inflows hit $1.19 billion daily, it’s a crypto triumph. For investors, it’s validation—will $200,000 BTC follow? The assets accumulate. Tradingview
