Bitcoin ETF Statistics 2026: Flows, Fees, Holdings

Ten US spot bitcoin exchange-traded products held 1,199,575.77 bitcoin between them as of June 30, 2026, worth a combined $70.78 billion. Each trust lodged a Form 10-Q with the SEC for that quarter, and the bitcoin ETF statistics below all trace back to those filings. The iShares Bitcoin Trust ETF held 734,261 bitcoin of that total on its own. The trust sits inside BlackRock, whose wider asset base dwarfs the bitcoin position many times over.

The same filings record a contraction. Across the nine trusts that disclosed bitcoin quantities at both December 31, 2025 and June 30, 2026, holdings fell by 93,308.46 bitcoin over the half-year. Only three of them finished the period holding more coin than they started with. Every figure carries a fixed reporting date and a permanent EDGAR URL, because it comes from a filing rather than a daily flow tracker.

Bitcoin ETF Sponsor Fees Compared

• Grayscale Bitcoin Trust ETF charges a Sponsor’s Fee of 1.5% of the aggregate value of the Trust’s assets, less its liabilities.
• Grayscale Bitcoin Mini Trust ETF charges 0.15% on the same basis, the lowest rate in the group.
• Bitwise Bitcoin ETF charges a Sponsor Fee of 0.20% per annum of the Trust’s bitcoin holdings.
• ARK 21Shares Bitcoin ETF charges a unitary Sponsor Fee of 0.21% of the Trust’s NAV, and incurred $2,756,701 in the six months ended June 30, 2026.
• Fidelity Wise Origin Bitcoin Fund charges a unified fee of 0.25% of the Trust’s Bitcoin Holdings.
• VanEck Bitcoin ETF charges 0.20% of average daily net assets on assets over $2.5 billion, having waived the entire Sponsor Fee below that level through July 31, 2026.

Source: SEC Form 10-Q filings, June 30, 2026

CoinShares Bitcoin ETF accrues its Sponsor Fee at an annual rate of 0.25% of the Trust’s bitcoin holdings. Invesco Galaxy Bitcoin ETF pays a unified fee equal to 0.25% per annum of the daily total net assets of the Trust. WisdomTree Bitcoin Fund will pay a unified fee of 0.25% per annum, which the Sponsor may waive in whole or in part for stated periods.

Worth noting: VanEck’s headline 0.20% rate and its effective rate were different things in this period. Its filing waives the entire Sponsor Fee on the first $2.5 billion of assets through July 31, 2026, charging the stated rate only on assets over that level. The trust held $958,827,545 at June 30, well inside that ceiling, so the rate it actually applied was zero.

Who Collects the Bitcoin ETF Fee Revenue

• The ten trusts carried a combined annualised sponsor-fee run rate of $271.3 million at June 30, 2026.
• Grayscale Bitcoin Trust ETF alone accounts for $122.0 million of that figure.
• IBIT, holding five times the assets, contributes $108.5 million.
• The older Grayscale trust held 11.49% of the category’s assets.
• Fidelity’s fund contributes $25.8 million on the second-largest asset base.
• Grayscale’s Mini Trust contributes $4.8 million despite holding more bitcoin than six other trusts.

By the numbers: Grayscale Bitcoin Trust ETF collects 45.0% of every sponsor-fee dollar in the US spot bitcoin ETF category while holding 11.49% of its assets. IBIT, five times its size, contributes $108.5 million. The gap is the rate doing the work, not the asset base.

Rank the trusts by size, and one order appears; rank them by what the sponsor earns, and the order inverts at the top. That split between headline scale and underlying economics recurs across the sector.

Bitcoin ETF Flows in the First Half of 2026

• Nine trusts disclosing both dates shed a net 93,308.46 bitcoin between December 31, 2025 and June 30, 2026.
• IBIT gave up 36,531 bitcoin, the largest absolute fall in the group.
• Fidelity’s fund gave up 27,301 bitcoin, close behind on a much smaller base.
• Grayscale’s Mini Trust added 5,805.46 bitcoin, the largest gain.
• VanEck’s trust added 431.30 bitcoin, and CoinShares added 97 bitcoin.
• Fidelity’s fund issued 49,450,000 Shares and redeemed 80,525,000 across the six months.

Are Bitcoin ETF flows positive or negative?

Negative over the first half of 2026, based on the filed evidence. The nine trusts reporting both dates ended the period 7.23% lighter in bitcoin, and six of the nine shrank. Direction can reverse inside a quarter, so any flow figure is only as current as the reporting date attached to it.

IBIT Creations and Redemptions by Quarter

• IBIT took $7,758,988,443 in contributions for Shares issued during the March quarter.
• It paid out $6,646,969,666 in distributions for Shares redeemed over the same three months.
• Contributions fell to $4,285,909,689 in the June quarter while redemptions rose to $7,236,496,312.
• Net redemptions across the half-year came to $1.84 billion.
• The trust issued 277,840,000 Shares and redeemed 340,480,000 across the six months.
• Price and valuation movement, not investor exit, drove 92.3% of the fall in net assets.
• In billions, the four gross flows read 7.76 for March-quarter creations, 6.65 for its redemptions, 4.29 for June-quarter creations, and 7.24 for its redemptions.

Splitting the decline this way is what separates useful bitcoin ETF statistics from a headline, because the two causes carry different meanings. A fund that shrinks on price is holding the same investor base through a drawdown; a fund that shrinks on redemptions is losing it. IBIT’s filing points overwhelmingly at the first.

Book Cost Versus Market Value Across the Funds

• Grayscale Bitcoin Trust ETF carried its bitcoin at a book cost of $2.55 billion against a June 30 fair value of $8.14 billion.
• IBIT carried its bitcoin at a book cost of $61.00 billion against a fair value of $43.40 billion.
• ARK 21Shares carried bitcoin at a book cost of $2.74 billion against a fair value of $1.89 billion.
• Bitwise Bitcoin ETF carried bitcoin at a book cost of $1,891.2 million against a fair value of $2,126.0 million.
• WisdomTree Bitcoin Fund carried bitcoin at a book cost of $158.6 million against a fair value of $136.5 million.
• Invesco Galaxy carried bitcoin at a book cost of $233.0 million against a fair value of $315.9 million.
• VanEck carried bitcoin at a book cost of $1,291.7 million against a fair value of $958.8 million.
• Its fair value sat at 3.185 times its book cost, the highest ratio in the group.

Source: SEC Form 10-Q filings, June 30 2026

Key finding: IBIT’s bitcoin carried a June 30 fair value of 0.711 times its book cost, because the trust bought most of it through creation baskets struck at higher prices during 2024 and 2025. The older Grayscale trust shows the inverse at 3.185 times cost, because its coin was accumulated years before the ETF conversion.

Grayscale’s Two Bitcoin Funds and the Fee Migration

• The older Grayscale trust charges 1.5% of the aggregate value of the Trust’s assets, less its liabilities.
• Grayscale Bitcoin Mini Trust ETF charges 0.15% on identical wording, differing only in the rate.
• The costlier trust lost 27,085.74 bitcoin over the half-year.
• The cheaper one gained 5,805.46 bitcoin over the same period.
• Shares outstanding in the older trust fell from 211,920,100 to 178,580,100.
• Shares outstanding in the Mini rose from 109,539,963 to 122,749,963.

One sponsor, one asset, two fee tiers, and holders moving opposite ways on each. Cost, not a view on bitcoin, moved this money.

Bitcoin ETF Share of Circulating Supply

• Blockchain.com’s series recorded a cumulative issued supply of 20,050,440.625 bitcoin at the close of the June quarter.
• The ten trusts together held 5.98% of that circulating supply.
• IBIT on its own held 3.66% of every bitcoin then in existence.
• The combined ETF position stood at 1,199,575.77 bitcoin.
• Blockchain.com’s total-supply endpoint returned 2007970300000000 satoshis on the September query date.

A single-digit share still reshapes who holds the float, a split visible in allocation data on retirement portfolios.

Buyer mix matters as much as the total. Hedge funds trade the wrapper for basis reasons, and retail investors reach it through brokerage accounts that never touched a private key.

In-Kind Creations and Redemptions After the 2025 Rule Change

• The Commission’s orders were a departure from the earlier spot bitcoin and ether ETPs, which were limited to creations and redemptions on an in-cash basis.
• The SEC issued orders permitting in-kind creations and redemptions by authorized participants for the Trust on July 29, 2025.
• An amendment to the Trust’s registration statement on Form S-1 was declared effective on July 31, 2025.
• IBIT recorded $771,263,116 of bitcoin paid for the in-kind redemption of Shares in the three months ended June 30, 2026.
• A second footnote records $460,163,388 of bitcoin paid for in-kind redemptions in the six months ended June 30, 2026. The filing attaches those two amounts to different columns of one line, and the six-month figure sits below the three-month one, so they do not add to a half-year total.
• In-kind delivery covered 10.66% of IBIT’s gross redemptions in the June 2026 quarter.
• The orders cover Bitcoin and Ethereum products alike, so both assets now share one creation mechanism.

Source: SEC Press Release 2025-101, July 29 2025

Why it matters: The Commission also approved options on certain spot bitcoin ETPs, Flexible Exchange (FLEX) options on shares of certain BTC-based ETPs, and an increase of position limits up to 250,000 contracts. Options change how a fund is hedged and therefore how tightly its shares track the coin, which moved these products onto the same operating footing as long-established commodity ETPs.

How US Spot Bitcoin ETFs Reached the Market

• The Commission disapproved more than 20 exchange rule filings for spot bitcoin ETPs between 2018 and March 2023.
• The D.C. Circuit vacated the Grayscale order and remanded the matter, which the Chairman cited as the change in circumstances.
• Approval turned on whether an exchange held a comprehensive surveillance-sharing agreement with a regulated market of significant size related to the underlying bitcoin assets. That reasoning is set out in the SEC’s approval order. The SEC and CFTC crypto enforcement data show the same litigation-first pattern across the sector.
• IBIT’s registration statement was declared effective on January 10, 2024, and its Shares listed on Nasdaq on January 11, 2024.
• The Sponsor’s fee started accruing at an annualised rate of 0.25% of net asset value on January 5, 2024.

The bitcoin ETF statistics above rest on a framework that arrived through litigation rather than rulemaking, a pattern that recurs across crypto policy.

What does a Bitcoin ETF sponsor fee cost an investor?

The fee is deducted from trust assets rather than billed separately. It reaches the holder as a slow reduction in the bitcoin backing each share. Grayscale’s Sponsor’s Fee accrues daily in US dollars and is payable in Bitcoin, daily in arrears. Bitwise applies the same mechanism at 0.20%, reducing the trust’s net asset value each day by the accrued amount.

The spread compounds over holding periods. On identical wording, Grayscale’s two trusts charge 1.5% and 0.15% of assets less liabilities. That difference is the mechanical reason a share count can fall in one fund while rising in another holding exactly the same asset.

Do Bitcoin ETFs hold actual bitcoin?

Yes. Each trust’s Schedule of Investments lists bitcoin as its sole holding, at a stated quantity and fair value. That is why bitcoin ETF statistics tie to a coin count rather than an index weighting.

The iShares fact sheet lists a single holding, BITCOIN at 100.00% of the portfolio, with USD CASH at 0.00%. The WisdomTree Bitcoin Fund reported a net closing balance of 2,309.689 bitcoins valued at $135,360,252.

Shares are not redeemable coin-for-coin by individual investors. Shares of the Trust are not redeemable except in large, aggregated units called Baskets. Only registered broker-dealers that become authorized participants may purchase or redeem Baskets. Only authorized participants deal with the trust directly; everyone else trades the share. Network-level Bitcoin data covers the coin itself.

Conclusion

The ten trusts closed the June 2026 quarter holding 1,199,575.77 bitcoin worth $70.78 billion. IBIT holds the clear majority; the remaining nine split what is left. Two things separate these bitcoin ETF statistics from the tracker prints. The half-year was a contraction in coin terms, and the category’s fee revenue concentrates in a trust that ranks third by size.

The next filings land after the September quarter closes. The regulatory footing beneath them is settled in a way it was not two years ago, and institutional demand still shows up in the allocation data on pension funds.
