BTC: Average Cost Basis of US Spot ETF Deposits
US Spot Bitcoin ETF Cost Basis (Daily, Issuer Files) was $77,194.73 on 5 Nov 2026 (latest daily value).
The average price the US spot bitcoin ETFs collected daily paid for the bitcoin they hold: their total cost divided by their bitcoin, in US dollars per BTC.
Why use it. It is where ETF holders as a group break even: with the price above it the funds' bitcoin is worth more than it cost, below it less. Large inflows at prices above the line pull it up. How to read it. One point per US trading day, dated the day the holdings are as of, on the same axis as the price. The gap between the price and the line is the funds' average unrealized profit or loss per BTC; outflows leave at each fund's average cost and do not move it.
Calculation. The sum over the included funds of each fund's cost (from its average-cost ledger) divided by the sum of their bitcoin on the day. Funds: IBIT (BlackRock), FBTC (Fidelity), BITB (Bitwise), ARKB (21Shares), HODL (VanEck) and EZBC (Franklin Templeton), the funds collected daily whose holdings can be followed back to their launch. FBTC (Fidelity) and BITB (Bitwise) publish only the current day, so their holdings before their daily record here (from 22 October 2026) come from their own quarter-end filings (10-Q and 10-K): each quarter's change is valued at the mean of our daily closes over that quarter, because when inside it the coins moved is not known, and that part of the cost is marked estimated. Funds whose issuers' sites refuse automated reads (CoinShares, Grayscale, Morgan Stanley, WisdomTree and Invesco since 30 October 2026) are not in the daily figures, so not in the cost basis either; we do not work around that. Invesco's BTCO is in the cost basis from 22 October 2026 to 29 October 2026, its last collected day (except 28 October 2026, a day its file could not be read), and left out from 30 October 2026: its holdings are not carried forward at the last read. Method: each fund keeps an average-cost ledger over its daily holdings. Coins it adds cost the change times CryptoKeyhole's own USD close of that UTC day; coins it removes (redemptions, bitcoin sold to pay its fee, cash payouts of staking rewards) leave at its average cost, so they do not move its cost basis, and realize a profit or loss of the coins removed times (the close - the average cost). A change across days with no figure in between (a short gap in an issuer's history, a quarter before the daily record) is valued at the mean of our closes over those days. The cost basis is the funds' total cost divided by their total bitcoin, on days every included fund has published. Source: the funds' own daily holdings files, as on the ETF flows charts (read by CryptoKeyhole every 5 minutes until each issuer has published), their own quarterly SEC filings for the time before a fund's daily record, and our own BTC/USD index for prices. The figure for a day needs that day's close, so it appears once the UTC day has ended and every included fund has published. Limitations: the funds' cost is reconstructed from their holdings, not from what each shareholder paid for their shares (that depends on the share price on the day each investor bought, which the funds do not publish); creations are valued at our close of the day rather than at the benchmark price a fund used for its NAV that afternoon. A step on a day funds join the daily coverage is their cost entering the figure, not a change in what holders paid.
