The same coin, two trusts
ARKB and BTC hold the same asset. Both are 1933 Act trusts holding Bitcoin through a custodian, so neither has a portfolio to compare: the whole of each fund is one line. Over the same days, ARKB finished 0.13 of a percentage point behind Bitcoin and BTC 0.09 of a percentage point behind, so BTC kept more of what holding the coin gave, by 0.04 of a percentage point. That gap is the fee, the custody, the creation and redemption friction and the market’s pricing of the shares, compounded into one number. ARKB has 202 more days of record than BTC, and a longer record is a longer window over which a cost can show itself.

ARKB
ARKB holds Bitcoin through a custodian and trades on an exchange, so a holder gets the coin’s return inside a brokerage account rather than a wallet. Over the year to Oct 28, 2026, Bitcoin moved −28.3% and ARKB returned −28.4%. That leaves it 0.13 of a percentage point behind. That difference is the fee, the custody cost, the friction of creating and redeeming shares in blocks, and whatever the market paid for the shares rather than for the coin, all of it together. It is the only number on this page the sponsor does not publish itself. ARKB charges 0.21% a year and finished 0.1% behind Bitcoin, so the fee is almost the whole of the difference. A spot trust is not a registered investment company. It files a 10-K rather than an N-PORT, and its holding is one line: the Bitcoin it custodies.
