Bitcoin ETF Flows and Holdings: Who Holds How Much Bitcoin?

Short answer: Bitcoin ETF flows show how much money investors put into or pull out of the US spot ETFs on a given day. Since launch on Jan 11, 2024, a net $55.1 billion has flowed in. Together, the twelve US spot ETFs hold about 1.27 million BTC, a little over 6% of all 21 million bitcoin. Since October 2025, money has been flowing out on balance (as of Nov 12, 2026).

Every morning you read headlines like "Record outflows from bitcoin ETFs" or "BlackRock buys 5’000 bitcoin". Sounds important, but what is behind it? Here you'll see what bitcoin ETF flows really measure, who holds how many bitcoin, when the money came and went, and why you as a long-term holder need to worry about it less than the headlines suggest.

What is a bitcoin spot ETF?

A bitcoin spot ETF is an exchange-traded fund that buys real bitcoin and stores them with a custodian. Each fund share stands for a fixed, slowly shrinking amount of bitcoin. "Spot" means the fund holds the coins itself, not futures contracts.

The US Securities and Exchange Commission (SEC) approved the first eleven funds on Jan 10, 2024, and trading began on Jan 11, 2024. Bitcoin cost about $46’400 at the time. More funds have joined since, most recently the Morgan Stanley Bitcoin Trust in April 2026.

An ETF is not a company like Strategy: it doesn't borrow money, doesn't issue preferred stock and only buys bitcoin when investors want new shares. How real treasury companies work by contrast is explained in the overview Bitcoin treasury companies.

How bitcoin ETF flows come about

When you buy an ETF share on the exchange, you usually buy it from another investor. The fund doesn't notice. A flow only arises when demand is greater than supply:

1. The share becomes more expensive than the bitcoin behind it. Many buyers, few sellers.
2. A wholesale trader steps in. So-called authorized participants (mostly big banks and trading firms) have the fund issue new shares.
3. The fund buys bitcoin. For the new shares it receives cash and buys bitcoin with it, or it receives the bitcoin directly. The SEC has allowed this exchange in bitcoin instead of dollars since Jul 29, 2025.
4. Outflows work the other way round. Shares are returned, and the fund hands over bitcoin.

So the daily "flow" is the number of new or returned shares times their value. The issuers report their holdings every trading day; services such as Farside Investors add up the flows of all funds from these reports.

Bitcoin ETF holdings: who holds how much?

Together, the twelve US spot ETFs hold about 1’265’800 BTC. That is 6.0% of all bitcoin that can ever exist and 6.3% of the bitcoin that exist today (about 20.1 million). At the price on Nov 13, 2026, that is about €80.1 billion or CHF 73.9 billion.

Holdings: bitcoin-powerlaw.com's treasury overview, from the issuers' reports and their quarterly SEC filings. Fees: quarterly reports (10-Q) at the SEC, not checked for HODL. Morgan Stanley and WisdomTree as of Jun 30, 2026; their holdings are higher by now.

IBIT alone holds almost as many bitcoin as Strategy, the largest treasury company (more in the profile of Strategy stock). On top of that come ETFs outside the US, for example about 34’000 BTC in Canada in two funds from Purpose and Fidelity. All states together hold only about half as much as the US ETFs, about 646’000 BTC; exactly who is shown in the article Countries holding bitcoin.

The special role of Grayscale GBTC

GBTC was already a bitcoin fund before 2024, but without redemption of shares. That is why at times in late 2022 it traded almost half below the value of its bitcoin. On Dec 31, 2023, it held 619’526 BTC. With the conversion into an ETF, investors could exit at full value for the first time, and many did: also because of the high fee of 1.5% a year, six times as much as IBIT.

Since then, a net $28.1 billion has flowed out of GBTC. Today it still holds 123’694 BTC. Grayscale moved part of the coins to its own investors in the cheaper Mini Trust (BTC) on Jul 31, 2024. What discounts to bitcoin value mean and why ETFs hardly know them thanks to redemption is explained in the article mNAV explained.

Bitcoin ETF flows since 2024 at a glance

The flows came in waves. In 2024 a net $35.2 billion flowed in, in 2025 another $21.3 billion. So far 2026 is $1.5 billion negative.

Flows: Farside Investors, all US spot ETFs, as of Nov 12, 2026. Bitcoin amount: our own calculation, each daily flow divided by that day's bitcoin closing price (Yahoo Finance, BTC-USD). Zone per bitcoin-powerlaw.com's methodology.

The biggest days: +$1.37 billion on Nov 7, 2024, two days after the US presidential election, and −$1.11 billion on Feb 25, 2025. Of 729 trading days, 421 had an inflow and 292 an outflow; the rest were zero.

What do the flows say about the bitcoin price?

This is where it gets interesting for you as a holder. Put the flows next to the Power Law model and a clear pattern appears:

• In the "Hot" zone (the upper half of the way from the trend to the top band), a net $36.0 billion flowed in on 199 trading days.
• In the "Fair" zone (around the trend), a net $24.3 billion flowed in on 398 trading days.
• In the "Accumulation" zone (from the floor to halfway to the trend), a net $5.0 billion flowed out on 131 trading days.
• At the floor (Jun 30, 2026, bitcoin at $58’559), $0.2 billion flowed out on that one day.

On balance, ETF investors bought when bitcoin was fairly valued or hot according to the model, and sold when it was cheap. That is no accusation, just human: people buy what is rising. For you it means the headline "record outflows" says nothing about whether bitcoin is expensive or cheap. It only shows what the crowd is feeling right now.

Rule of thumb: ETF flows follow the price more often than they lead it. Where bitcoin stands in its long-term trend is shown by the model, not by the daily flow.

On Nov 13, 2026, bitcoin stood at 0.64 times the trend, in the Accumulation zone and about 4% above the floor of €60’575 (CHF 55’923). The average price of all ETF inflows is about $84’650. At a price of $70’018, ETF investors as a group are therefore about 17% below their cost basis. That explains part of the outflows: if you're in the red and get nervous, you sell.

The floor is a model value, not a guarantee. Where it lies on a given day you can work out in the floor calculator. How the model is built and where its limits are is in the methodology.

ETF or your own bitcoin: what the fee costs

An ETF costs you part of your bitcoin every year. The funds continually sell small amounts to pay their fee. The bitcoin per share therefore shrinks year after year, no matter how the price moves. Together, all US spot ETFs give up at least about 4’500 BTC a year this way, a good 40% of that from GBTC alone.

Can you buy US ETFs from Germany, Austria or Switzerland?

Usually not. US funds have no key information document (KID) as required by EU law, so most brokers don't let retail investors in the EU buy them. In Switzerland it depends on the broker. Instead, you can get bitcoin ETPs here: securities that are also backed by real bitcoin and cost similar fees. The guide Buying bitcoin shows the options.

On taxes in Germany: your own bitcoin and physically backed ETPs with a delivery claim are tax-free after a one-year holding period, while gains from funds fall under the Abgeltungsteuer (flat withholding tax on capital income), with no holding period. How ETPs are built and what they cost is compared in Bitcoin ETP or real bitcoin. The details are in the article Bitcoin taxes in Germany.

Bitcoin ETF, treasury stock or your own bitcoin?

An ETF is the easiest way to put bitcoin into a brokerage account, for a pension fund or an asset manager, say. For your own long-term reserve, bitcoin in your own custody is cheaper and more independent. How to set that up safely is shown in the guide How to store bitcoin safely. How many bitcoin you accumulate with a monthly amount you can work out in the savings plan calculator.
