Overview
FBTC and IBIT are both spot bitcoin ETFs launched within a day of each other in January 2024, offering direct exposure to bitcoin's price without leverage or derivatives. The funds are structurally identical—both hold physical bitcoin and charge the same 0.25% expense ratio—but differ significantly in asset size, with IBIT holding $66.3B in assets versus FBTC's $14.7B.
How they differ
The single biggest difference is scale: IBIT has accumulated $66.3B compared to $14.7B, more than four times larger. Both charge 0.25% in annual fees and offer identical distribution structures—neither pays distributions. Their betas are nearly matched at 1.8779 and 1.8887, reflecting the same underlying bitcoin volatility. This distinction may influence which custodians or platforms offer easier access. Share price also differs—FBTC trades at $70.85 per share versus $46.15 for IBIT—but this reflects only the fund's share structure and does not affect the economic exposure to bitcoin.
Who each is best for
FBTC: Fits investors with existing Fidelity brokerage relationships or platforms that feature Fidelity products prominently, where account integration may streamline bitcoin exposure.
Key risks to know
- Bitcoin volatility and price movement. Both funds track bitcoin directly, exposing holders to sharp price swings. The 1.8779 and 1.8887 betas indicate sensitivity roughly double that of broad equities during market moves.
- Regulatory and custody risk. Bitcoin's regulatory status remains uncertain in many jurisdictions. Custody arrangements—how bitcoin is stored and secured against theft or loss—differ between operators and warrant independent verification.
- Spot price tracking divergence. While both hold physical bitcoin, small deviations between the fund's net asset value and the real-time spot price can occur due to custody fees, deposit/withdrawal mechanics, or trading spreads, potentially reducing returns over time.
- Adoption and liquidity risk. Bitcoin's price depends heavily on demand and adoption by institutions and retail investors. A sustained decline in adoption interest or regulatory crackdowns could suppress demand and prices.
Bottom line
If you already use Fidelity's ecosystem, FBTC offers seamless integration at an identical fee to IBIT. Both charge 0.25% and track the same underlying with similar volatility—the choice hinges on platform convenience and confidence in bitcoin's long-term role as an investable asset class.
