What happened
On 15 June 2023 a registration statement on Form S-1 was filed with the Securities and Exchange Commission for the iShares Bitcoin Trust, sponsored by a subsidiary of BlackRock. The trust would hold bitcoin directly, and shares in it would be listed on a national securities exchange.
What it changes
The filing itself changes nothing about what is permitted. It is worth being precise about why, because the process has two tracks and most coverage collapses them into one.
An S-1 registers the securities being offered. It does not authorise anyone to list them. For an exchange-traded product to trade, the listing exchange must separately file a proposed rule change with the Commission, and the Commission must approve that rule change after a public comment period. The registration statement is the smaller half of the problem.
What is different here is the filer rather than the filing. The largest asset manager in the world putting its name to a spot bitcoin product is a judgment that the remaining obstacle is addressable. That is information about what one firm believes, not about what the agency will decide.
What it does not change
The standard has not moved, and it is a specific one. In its 2018 order disapproving the Winklevoss Bitcoin Trust, the Commission held that where an exchange cannot otherwise show it can prevent fraud and manipulation, it "must enter into a surveillance-sharing agreement with a regulated market of significant size."
The order then defines that phrase in a way that has proved hard to satisfy: a market where "there is a reasonable likelihood that a person attempting to manipulate the ETP would also have to trade on that market", and where "it is unlikely that trading in the ETP would be the predominant influence on prices in that market." The Commission's finding was that the exchange "has not established that it has entered into, or currently could enter into" such an agreement.
Nothing about a new applicant changes that test. Applications have been filed and refused for roughly a decade against it.
Nor does any of this change what a share would be. A trust share is an interest in an entity that holds coins through a custodian, which is price exposure and not possession of bitcoin.
Context
The Commission has approved products that reference bitcoin without holding it. The first US bitcoin futures ETF launched in October 2021 under the Investment Company Act, while every spot application remained refused. That asymmetry, regulated funds tracking bitcoin futures but none holding bitcoin, is the tension this filing walks into.
The 2018 order left a door open, saying an exchange "may be able to demonstrate" it can address manipulation risk by sharing surveillance information with a regulated market of significant size. Whether any exchange can now walk through that door is exactly the question, and a registration statement filed today does not answer it.
