*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.
Hashdex’s DEFI, the 13th fund, announced in August that it is shutting down and no longer holds bitcoin, so it is not in the table.

What the numbers say
One fund dominates. IBIT holds 805,222 BTC, more than all eleven other funds combined (488,596 BTC). It also has the deepest trading volume and options market, which is why large holders keep adding to it: Jane Street alone disclosed more than $1 billion in Bitcoin ETFs, led by IBIT.
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 more than $1,300 on a single $10,000 position. GBTC still holds about $10.9 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 almost $28 billion to outflows since January 2024, while Grayscale’s own Mini Trust (BTC), at 0.15%, has gained almost $3 billion. Together the two still hold 14.7% of all ETF bitcoin.
Newcomers can still win. MSBT launched in April 2026, more than two years after the others, and already holds more bitcoin than BRRR, EZBC, BTCO and BTCW. Its low fee and Morgan Stanley’s wealth-management network likely both help.
Institutions are not leaving on dips. 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 $86,160 on October 5).
- 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. The SEC approved 3x leveraged Bitcoin and Ether ETPs in early October; they are not included here.
FAQ
How many spot Bitcoin ETFs are there in the US? Twelve are trading and hold bitcoin as of October 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 805,222 BTC worth about $69.4 billion, or 62% 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? 1,293,818 BTC as of October 5, 2026, about 6.16% of the 21 million bitcoin that will ever exist.
