As Bitcoin continues to gain legitimacy in mainstream finance, spot Bitcoin exchange-traded funds (ETFs) have emerged as a preferred vehicle for investors seeking exposure to the leading cryptocurrency. Among the most prominent options are IBIT (iShares Bitcoin Trust) and FBTC (Fidelity Wise Origin Bitcoin Fund). Both offer direct access to Bitcoin’s price performance without the complexities of self-custody or trading on crypto exchanges.
This in-depth comparison explores the key differences and similarities between IBIT and FBTC across critical factors such as fund providers, expense ratios, performance metrics, risk profiles, and investment strategy—helping you make an informed decision aligned with your financial goals.
Understanding IBIT: iShares Bitcoin Trust
The iShares Bitcoin Trust, traded under the ticker IBIT, is managed by BlackRock, the world’s largest asset manager. Launched on January 5, 2024, IBIT was among the first wave of approved spot Bitcoin ETFs in the United States. It aims to track the price of Bitcoin by holding the actual cryptocurrency, providing investors with a regulated, transparent, and liquid way to gain long exposure to BTC while shorting the US dollar.
IBIT is built for integration into traditional brokerage accounts, making it accessible to both retail and institutional investors who prefer familiar investment channels over crypto-native platforms.

Exploring FBTC: Fidelity Wise Origin Bitcoin Fund
The Fidelity Wise Origin Bitcoin Fund, known by its ticker FBTC, launched shortly after IBIT on January 11, 2024. Offered by Fidelity Investments, a trusted name in retirement and investment services, FBTC also provides direct exposure to Bitcoin’s market price through physical BTC holdings.
Like IBIT, FBTC follows a “vanilla” investment strategy—meaning it holds only Bitcoin with no leverage, derivatives, or complex hedging mechanisms. Its structure is designed for simplicity, transparency, and regulatory compliance, appealing to conservative investors looking to enter the digital asset space through a reputable financial institution.
Core Comparison: IBIT vs FBTC
Below is a detailed side-by-side analysis of both ETFs based on essential investment criteria:
Fund Provider and Reputation
- IBIT: Backed by BlackRock, a global leader in asset management with over $10 trillion in assets under management (AUM). BlackRock's entry into the crypto space signals strong institutional confidence in Bitcoin’s long-term value.
- FBTC: Sponsored by Fidelity, which has been actively involved in blockchain and digital assets for years, including operating a Bitcoin custody solution and launching crypto trading for institutional clients.
Both institutions bring decades of financial expertise and robust infrastructure, enhancing trust in their respective ETF offerings.
Expense Ratio: Cost Efficiency Matters
One of the most significant differences lies in cost:
- IBIT carries an expense ratio of 0.12%, which is competitive but not the lowest in the market.
- FBTC, notably, offers a 0.00% expense ratio at launch—a powerful advantage that reduces drag on returns over time.
While promotional fee waivers may not last indefinitely, FBTC’s current pricing makes it highly attractive for cost-conscious investors.
Inception Date and Market Entry
- IBIT launched on January 5, 2024, giving it a slight first-mover advantage.
- FBTC followed six days later on January 11, 2024.
Although IBIT entered the market earlier, FBTC quickly gained traction due to Fidelity’s strong brand recognition and zero-fee structure.
Underlying Index and Asset Composition
Both ETFs track the CME Bitcoin Reference Rate (BRR), a widely accepted benchmark that calculates the daily reference price of Bitcoin using trading activity across major exchanges.
Additionally:
- Both hold 100% physical Bitcoin.
- Both are non-leveraged and classified under the cryptocurrency asset class.
- Both are US-listed, denominated in cryptocurrency value, and provide global exposure.
This alignment ensures that performance differences will primarily stem from operational efficiency and inflow dynamics rather than strategy divergence.
Performance and Risk Analysis
While historical performance data since inception remains limited due to their recent launch, early trends suggest both funds closely track Bitcoin’s price with minimal tracking error.
Key Performance Metrics (as of mid-2025)
- Cumulative Returns: Nearly identical, reflecting BTC’s price movement.
- Sharpe Ratio: Slight edge to FBTC due to lower expenses improving risk-adjusted returns.
- Volatility: Comparable levels, as both are directly exposed to Bitcoin’s inherent price swings.
- Drawdowns: Mirror Bitcoin’s market corrections; no significant deviation between the two.

Key findings:
- Median 10-year return projections exceed 15% annualized under base-case assumptions.
