What's inside
Fidelity Wise Origin Bitcoin Fund is a straightforward vehicle for bitcoin exposure, holding 99.98% of assets in Bitcoin (XBTUSD) and the remainder in net other assets. Sector allocation is not reported, but with just two holdings and over two years on the market, the fund is focused exclusively on tracking bitcoin’s price. There are no notable quirks or leverage resets, and the fund does not track a named index.
iShares Bitcoin Trust ETF is even more concentrated, with 100% of its portfolio in bitcoin and cash, and no sector diversification. Its assets under management (AUM) are much larger, at roughly $64.8 billion, and the fund’s top holdings mirror FBTC’s, with bitcoin dominating the exposure. Like FBTC, IBIT is structured for simplicity, with no additional overlays or quirks.

What this means for investors
These are the two largest spot bitcoin ETFs available to investors, but IBIT is far and away the largest at around $65 billion in assets under management. FBTC is a distant second with about $17.7 billion.
There really is no difference in holdings, as both are 100% invested in bitcoin and have basically identical returns. Both are down about 16.3% year-to-date and 26% over the past 12 months, as of Feb. 4.
The similarities don’t end there, as the two ETFs carry the same expense ratio of 0.25%. IBIT had a lower ratio to start, but it is now 0.25% for new investors.
So, what, if anything, would give the edge to one of these ETFs over the other? Obviously, if you are a Fidelity brokerage customer, it would be more convenient to buy on the Fidelity platform and have custody handled in-house. It would also be kept with your other investments.
The advantage IBIT has is that it provides greater liquidity from significantly more trading volume. This typically results in lower trading costs and faster trade execution.
So, in reality, there is not a huge difference between the two aside from convenience for Fidelity brokerage customers and the liquidity edge for the iShares ETF.
