Every Bitcoin and crypto ETF, in one place

Tickers, real fees after waivers, assets, custodians and listing venues for the whole US market — plus the part most sites skip: how to actually place the trade, and when owning the coin outright makes more sense than owning the fund.

Three ways people arrive at this page

Most visitors want one of three things. They want a straight list of the funds with the fees attached. They want to understand what they would actually own before they commit money. Or they already know and just need to place the trade without fumbling the order ticket.

The directory is built around those three jobs. Nothing here is a sponsored placement, no issuer pays for a position in a table, and every number carries the date it was checked — because in this corner of the market a figure without a date is close to useless. Bitcoin moved roughly 25% in August 2026 alone, and since these funds are essentially one asset in a wrapper, their assets under management moved with it.

The short version

The six largest US spot Bitcoin ETFs

Between them these six hold more than nine of every ten dollars invested in the category. Everything below them is a rounding error by comparison — which matters, because size drives the spread you pay every time you trade.

Analyst note

The concentration in this table is the single most under-discussed fact in the category. IBIT alone holds around 60% of the assets and roughly 63% of the bitcoin. That is not a criticism of BlackRock — it is a description of where the liquidity went. In practice it means the difference between the largest fund and the smallest is not a rounding error in fees, it is the difference between a 0.03% spread and one three or four times wider. If you trade in size, or trade often, that gap will cost you more than the expense ratio.

The fundamentals

What a spot Bitcoin ETF actually is

A spot Bitcoin ETF is a trust that owns bitcoin and issues shares against it. You buy the shares through an ordinary brokerage account, exactly as you would buy Apple or an S&P 500 fund. The trust holds the coins with a qualified custodian, publishes what it owns every day, and the share price tracks the bitcoin price minus the sponsor's fee.

The wrapper is where the nuance lives. These funds are grantor trusts registered under the Securities Act of 1933 — they are not registered investment companies under the Investment Company Act of 1940, which is the law that governs almost every other ETF you have ever bought. That single structural fact carries real consequences, and very few articles spell them out.

What the wrapper gives you

  • Full '33 Act disclosure plus 10-K and 10-Q reporting
  • An independent qualified custodian and audited financials
  • A regulated broker under FINRA supervision
  • SIPC protection on the brokerage account itself
  • Eligibility inside an IRA, Roth IRA or 401(k)
  • Daily transparent pricing and an arbitrage mechanism

What it does not give you

  • An independent board with fiduciary duties over fees
  • The 1940 Act limits on leverage and affiliated transactions
  • Mandated diversification — this is one asset, full stop
  • Any protection whatsoever against the price falling
  • The ability to withdraw, spend or self-custody your bitcoin
  • Trading outside US market hours

The fund owns the bitcoin. You own a share that references it — which is the whole distinction, and the reason the wrapper suits some people and not others.

None of that makes these funds bad. For most people they are the most practical way to hold bitcoin exposure alongside the rest of a portfolio, particularly inside a tax-sheltered account. But "SEC-approved" is not the same as "safe", and SIPC coverage protects you against your broker failing — never against bitcoin falling 50%. That distinction is worth internalising before you size the position.

Worth knowing

Every one of these trusts pays its sponsor fee in bitcoin, by selling a sliver of its holdings. Because a grantor trust passes everything through to shareholders, each of those sales is a taxable disposition for you — even in a year when you never touched a single share. It is small, but it is real, and it appears on the tax documents of people who assumed they had a completely passive holding. We cover it in the tax guide.

Fees look tiny. Over a decade they are not.

The spread between the cheapest and most expensive spot Bitcoin ETF is roughly ten to one. Morgan Stanley's MSBT charges 0.14%. Grayscale's original GBTC charges 1.50%. On a $25,000 position that is $35 a year against $375 a year, for exposure to the identical asset held in broadly similar custody arrangements.

Grayscale's fee has driven roughly $17.5 billion out of GBTC since it converted, and the fund has shed something like 447,000 bitcoin. Its answer was to launch a second fund — the Mini Trust, ticker BTC — with the same sponsor, the same custody, and a 0.15% fee. If you are still sitting in GBTC in a taxable account, the calculation is genuinely awkward: switching triggers capital gains, staying costs 1.35 percentage points a year. There is no clean answer, only arithmetic specific to your cost basis.

There is a second cost most comparison tables ignore entirely: the bid-ask spread. IBIT trades at roughly a 0.03% median spread and quotes in penny increments. The smallest funds can be three or four times wider. Buy and hold for a decade and the expense ratio dominates; trade monthly and the spread does. Our fee page works through both, with the arithmetic laid out.

An ETF tracks the price. An exchange gives you the asset.

If you want bitcoin you can withdraw to your own wallet, send to someone, or buy at two in the morning, the fund wrapper is the wrong tool. A regulated exchange is the right one.

The real decision

Fund or coin?

This is the question underneath almost every other question on this site, and the honest answer is that it depends on what you want the exposure to do.

If bitcoin is a line item in a diversified portfolio, sitting in a retirement account next to index funds, rebalanced once a year and never thought about in between — the ETF is almost certainly the right wrapper. It is simple, it is tax-sheltered where it can be, and there are no private keys to lose.

If you want bitcoin because it is bearer property that settles without a counterparty — because you want to withdraw it, hold your own keys, move it across a border, spend it, or simply buy on a Sunday evening when something happens — then an ETF gives you almost none of what you came for. You would be buying a share that references the price, which is a completely different thing.

Plenty of people sensibly do both: the fund inside the IRA where it is tax-efficient, the coin on an exchange or in self-custody for everything else.

Market context

Where the category stands

The launch in January 2024 was the most successful ETF debut in history by almost any measure. Cumulative net inflows have reached roughly $54.8 billion, and the funds collectively hold something close to 6% of all the bitcoin that will ever exist.

The story since has been less linear than the headlines suggest. Category assets peaked around $158 billion in October 2025 and sat near $99.6 billion at the end of August 2026 — most of that swing is the bitcoin price rather than investors leaving, but not all of it. The first half of 2026 saw net outflows of about $5.4 billion, the first negative half-year since launch, with June alone taking out $4.5 billion. August then turned decisively positive at roughly $3 billion.

Two structural things changed in 2025 and both matter. In July the SEC allowed in-kind creations and redemptions, letting market makers deliver bitcoin rather than cash — which tightens spreads. In September it approved generic listing standards, so an exchange no longer needs a bespoke rule filing for each new product. That second change collapsed approval timelines from roughly eight months to something closer to two, and it is the direct cause of the flood of Solana, XRP and other single-asset funds that arrived through late 2025.

And in August 2026 the category recorded its first ever closure. Hashdex's DEFI wound down with about $14.7 million in assets. It will not be the last — several funds sit below the level at which a sponsor can plausibly cover its own costs.

Common questions

How many Bitcoin ETFs are there in the US?
Twelve US spot Bitcoin ETFs were trading as of September 2026. Eleven launched together on 11 January 2024 after the SEC approved them the day before, Grayscale added its low-cost Mini Trust in July 2024, and Morgan Stanley became the first major US bank to put its own name on one in April 2026. One fund, Hashdex's DEFI, closed in August 2026 — the first spot Bitcoin ETF ever to wind down. That count excludes futures funds, leveraged and inverse products, covered-call funds and mining equity ETFs, all of which are listed separately in our full crypto ETF list.
Which Bitcoin ETF has the lowest fee?
Morgan Stanley's MSBT carries the lowest standing sponsor fee at 0.14%, followed by Grayscale's Mini Trust (BTC) at 0.15% and Franklin's EZBC at 0.19%. But headline fees are only half the story: a fund with a wider bid-ask spread can cost a frequent trader more than a slightly higher expense ratio ever will. We break the maths down on the fee comparison page.
Is a Bitcoin ETF safer than buying Bitcoin directly?
It is different, not automatically safer. The ETF removes private-key risk and gives you a regulated broker, SIPC coverage on the account itself and easy access inside an IRA or 401(k). It does not remove price risk — these funds hold one extremely volatile asset. And it adds things direct ownership does not have: an annual fee, exchange trading hours, and the fact that you cannot withdraw, spend or self-custody what you own. See our side-by-side comparison.
Can I buy a Bitcoin ETF in my retirement account?
Usually yes. Because spot Bitcoin ETFs are exchange-listed securities, most brokers allow them in a traditional IRA, Roth IRA and many self-directed 401(k) plans. This is one of the clearest practical advantages of the fund wrapper — holding bitcoin itself in a mainstream retirement account generally requires a specialist self-directed IRA custodian. Individual plan rules still vary, so check with your provider.
Where do Bitcoin ETFs actually keep the bitcoin?
With a qualified custodian, held in cold storage. Coinbase Custody Trust Company holds roughly 80% of all bitcoin sitting inside US ETFs, which is a genuine concentration risk worth understanding. Fidelity is the notable exception — it self-custodies through Fidelity Digital Assets — and ARK 21Shares spreads its holdings across three custodians. Our issuers and custodians page maps who holds what.
