GBTC launched as a private trust in 2013 and converted to an ETF on January 11, 2024. Its negative all-time flow reflects investors leaving after the conversion, not losses. Rows may not add up exactly to the totals because of rounding.
Hashdex’s DEFI, the 13th fund, is shutting down and no longer holds bitcoin, so it is not in the table.
Bitbo also lists BlackRock’s iShares Bitcoin Premium Income ETF (BITA), with 785.5 BTC. BITA launched on June 9, 2026. It holds bitcoin but also sells call options on IBIT shares to earn income, which caps its gains above the option strike price. That makes it an income fund, not a plain spot fund, so it is not in the table or the totals. If you see a total of 1,289,954 BTC elsewhere, that figure includes BITA.

Flows through October 22, 2026. Friday, October 23, 2026 is not reported yet. Data: Farside Investors.
Last week (October 12 to October 16, 2026) the funds lost $228.4 million, the second losing week in a row. This week started with two of the best days of the month, +$526.7 million on October 19 and +$524.8 million on October 21, 2026, then turned on October 22, 2026, the worst day of October so far at −$635.6 million.
From October 1 to October 22, 2026, net flows stand at −$175.6 million over 16 trading days (9 days in, 7 days out). For each day’s top movers and each fund’s October total, see our October 2026 Bitcoin ETF flows page.
What the numbers say
One fund dominates. IBIT holds 811,478 BTC, more than all eleven other funds combined (477,690 BTC). It also has the deepest trading volume and options market, which draws large holders: Jane Street alone disclosed more than $1 billion in Bitcoin ETFs, led by IBIT. From October 1 to October 22, 2026, IBIT took in a net $865.5 million while the group as a whole lost money.
Fidelity is carrying the outflows. FBTC lost a net $556.7 million from October 1 to October 22, 2026, more than any other fund. Its holdings fell from 181,891 BTC on October 7, 2026 to 176,390 BTC on October 21, 2026.
Fees matter more than they look. On $10,000, the gap between MSBT (0.14%) and GBTC (1.50%) is $136 a year. Over ten years, with no change in the bitcoin price, that is $1,360 on a single $10,000 position. GBTC still holds about $10.2 billion. A likely reason is that many holders bought before the ETF conversion and would owe capital gains tax if they switched.
Grayscale’s split tells the same story. GBTC has lost about $28 billion to outflows since January 11, 2024, while Grayscale’s own Mini Trust (BTC), at 0.15%, has gained almost $3 billion. Together the two still hold 14.6% of all ETF bitcoin.
A newcomer is holding steady. MSBT launched on April 8, 2026, more than two years after the others, and already holds more bitcoin than BRRR, EZBC, BTCO and BTCW. It has not had a single outflow day in October 2026 and is up $26.2 million for the month. Its low fee and Morgan Stanley’s wealth-management network likely both help.
Institutions held through the second-quarter dip. In the second quarter of 2026, bitcoin fell 14.2%, yet institutional holdings of Bitcoin ETFs rose 7.5%.
How to read this tracker
- BTC held is the bitcoin the fund actually owns. It is the cleanest way to compare fund size, because it does not move with the price.
- Assets is BTC held multiplied by the bitcoin price on the “as of” date (about $81,473 on October 21, 2026, the price implied by Bitbo’s totals).
- Net flows is money in minus money out, in dollars, on the day it happened. A fund can have positive flows and still shrink in dollars if the price falls.
- Fee is the annual sponsor fee. It is taken from the fund’s assets daily, so you never see a bill, but your share is worth slightly less each day.
- Cost per $10,000 is simply the fee applied to a $10,000 position for one year.
Daily flows come from Farside Investors, which compiles issuer disclosures; holdings come from Bitbo. Issuers report with a one-day lag, so the most recent day can change slightly after publication.
What this tracker does not cover
This page covers only spot Bitcoin ETFs, which hold real bitcoin. Futures-based funds such as BITO, inverse funds and leveraged products work differently: they hold derivatives, not bitcoin, and their costs and risks are much higher. Option-income funds such as BITA are also left out, as explained above. The SEC has approved 3x leveraged Bitcoin and Ether ETPs; they are not included here either. For filings and SEC decisions as they happen, see our Bitcoin ETF news page.
FAQ
How many spot Bitcoin ETFs are there in the US? Twelve are trading and hold bitcoin as of October 21, 2026. A thirteenth, Hashdex’s DEFI, is closing and holds none.
Which spot Bitcoin ETF is the biggest? BlackRock’s iShares Bitcoin Trust (IBIT), with 811,478 BTC worth about $66.1 billion, or 62.9% of all bitcoin held by US spot ETFs.
Which spot Bitcoin ETF has the lowest fee? Morgan Stanley’s MSBT at 0.14% a year, followed by Grayscale’s Mini Trust (BTC) at 0.15% and Franklin’s EZBC at 0.19%.
Why is GBTC so expensive? GBTC kept a 1.50% fee from its years as a closed trust. Many long-time holders would owe capital gains tax if they sold, which likely keeps them in the fund and reduces the pressure on Grayscale to cut the fee. Grayscale’s Mini Trust offers the same exposure for 0.15%.
How much bitcoin do the ETFs hold in total? 1,289,168 BTC as of October 21, 2026, about 6.14% of the 21 million bitcoin that will ever exist. Adding BlackRock’s BITA income fund brings it to 1,289,954 BTC.
Is BITA a spot Bitcoin ETF? Not in the plain sense. It holds bitcoin, but it also sells call options on IBIT shares for income, which limits how much it can gain when bitcoin rises. We track it separately from the twelve spot funds.
How often is this page updated? Every Friday. Monthly totals are published separately at the start of each month.
