The U.S. SEC approved the listing and trading of spot bitcoin ETP shares on January 10, 2024, while explicitly stating that approval does not equal endorsement of bitcoin. Structurally, iShares Bitcoin Trust ETF (IBIT) sits outside CFTC commodity-pool oversight, holds its bitcoin through custodian Coinbase Custody Trust Company, and restricts creation and redemption to registered Authorized Participants — with net assets reaching $60,018,939,295 as of September 2, 2026.
When Did the SEC Approve Spot Bitcoin ETPs?
The SEC approved the listing and trading of a number of spot bitcoin exchange-traded product shares on January 10, 2024CITE:E1. The approval was announced in a statement issued under the name of then-Chair Gary Gensler, who wrote: "Today, the Commission approved the listing and trading of a number of spot bitcoin exchange-traded product (ETP) shares"CITE:E1.
Does SEC Approval Mean It Endorsed Bitcoin?
No — the SEC drew a explicit line between approving a listing and endorsing the underlying assetCITE:E2. In the same statement, the agency said: "While we approved the listing and trading of certain spot bitcoin ETP shares today, we did not approve or endorse bitcoin. Investors should remain cautious about the myriad risks associated with bitcoin and products whose value is tied to crypto"CITE:E2. That distinction — approval of a trading vehicle rather than approval of bitcoin itself — is the SEC's own framing, stated on the day of approvalCITE:E2.
What Is a Spot Bitcoin ETF's Regulatory Status?
IShares Bitcoin Trust ETF (IBIT) is not classified as a commodity pool under the Commodity Exchange Act of 1936, as amendedCITE:E3. Its prospectus states the Trust "is not a commodity pool for purposes of the Commodity Exchange Act," and that its sponsor "is not subject to regulation by the Commodity Futures Trading Commission… as a commodity pool operator or a commodity trading advisor with respect to the Trust"CITE:E3. This sets the spot structure apart from futures-based bitcoin ETFs, which do involve commodity futures contracts and CFTC-adjacent oversightCITE:E3.
Who Actually Holds the Bitcoin?
Coinbase Custody Trust Company, LLC is the named custodian holding IBIT's bitcoin on behalf of the TrustCITE:E4. The prospectus identifies the arrangement directly: "Coinbase Custody Trust Company, LLC (the 'Bitcoin Custodian') is the custodian for the Trust's bitcoin holdings"CITE:E4. Shareholders do not take delivery of bitcoin themselves; the Trust, through its custodian, holds the underlying assetCITE:E4.
How Do Creation and Redemption Work?
Only registered broker-dealers under contract with the sponsor and trustee, known as Authorized Participants, may create or redeem shares in fixed-size units called BasketsCITE:E5. The prospectus specifies: "Only registered broker-dealers that become authorized participants by entering into a contract with the Sponsor and the Trustee ('Authorized Participants') may purchase or redeem Baskets"CITE:E5. Retail investors buy and sell shares on an exchange rather than interacting with this creation/redemption mechanism directlyCITE:E5.
How Large Has the Spot Bitcoin ETF Market Grown?

What Advantage Does Holding Bitcoin Through an ETF Offer?
IBIT's shares are designed to offer exposure similar to owning bitcoin without requiring investors to acquire, hold, or trade the asset directlyCITE:E7. The prospectus states: "The Shares are intended to constitute a simple means of making an investment similar to an investment in bitcoin rather than by acquiring, holding and trading bitcoin directly on a peer-to-peer or other basis or via a digital asset platform"CITE:E7. In practice, that shifts the custody, private-key, and platform-selection burden from the individual investor to the Trust and its named custodianCITE:E4CITE:E7.
What This Means
The SEC's approval on January 10, 2024 opened the door to a trading vehicle, but the agency itself separated that act from any endorsement of bitcoinCITE:E1CITE:E2. What followed is a layered structure: a regulatory classification that keeps the product outside CFTC commodity-pool rulesCITE:E3, a single named custodian holding the underlying assetCITE:E4, and a creation/redemption process gated to registered Authorized Participants rather than open to retail investors directlyCITE:E5. The scale disclosed by BlackRock — $60,018,939,295 in net assets as of September 2, 2026 — shows this structure now operates at a size the 2024 approval did not itself specifyCITE:E6.
Author's Take・EffectStory 編輯部
The structure disclosed in IBIT's own prospectus is more revealing than the January 2024 approval headline: the SEC approved a listing while explicitly refusing to endorse the asset, and everything downstream — commodity-pool exemption, a single named custodian in Coinbase Custody Trust Company, and a creation/redemption chain restricted to registered Authorized Participants — is a governance choice, not a bitcoin verdict. What deserves watching going forward is custody concentration: with one custodian named in the prospectus holding the Trust's bitcoin, that single point in the chain carries more structural weight than the headline net-asset figure of $60,018,939,295 suggests.
