SEC recorded withdrawal of Cboe’s VanEck SolidX bitcoin trust proposal

The U.S. Securities and Exchange Commission issued Release No. 34-86995 on September 17, 2019, recording that Cboe BZX Exchange had withdrawn its proposed rule change to list SolidX Bitcoin Shares issued by the VanEck SolidX Bitcoin Trust.

The notice closed one of the most closely watched routes toward a U.S.-listed spot bitcoin exchange-traded product. It also removed the proposal before the SEC had to make a merits decision. The agency had extended its review to October 18, 2019, but BZX withdrew the filing on September 13. The September 17 document made that procedural result public in the SEC record.

That distinction matters. The SEC did not approve the product, disapprove it or publish a conclusion that the proposal satisfied—or failed—the Exchange Act. The legal record establishes a withdrawal, not a regulatory judgment on bitcoin itself.

The proposal’s path ended before a decision

BZX filed SR-CboeBZX-2019-004 on January 30, 2019. The proposal sought permission to list and trade shares under BZX’s rule for commodity-based trust shares. The SEC published it for comment on February 20, extended its initial review on March 29 and opened proceedings on May 20 to determine whether to approve or disapprove it.

On August 12, the SEC used the available extension to set October 18 as the deadline for action. Its September 17 withdrawal notice then stated only that BZX had withdrawn the proposal four days earlier. It gave no reason.

The precise actor is also important. Contemporaneous headlines often described VanEck and SolidX as withdrawing their ETF application. The formal exchange-rule filing, however, belonged to Cboe BZX, and the SEC notice says BZX withdrew it. SolidX was the trust sponsor identified in the earlier order, while Van Eck Securities was to assist with marketing.

What regulators had been examining

The SEC’s May 20 order had not prejudged the outcome. It said the proceeding was intended to analyze whether BZX’s proposal was consistent with the Exchange Act requirement that exchange rules prevent fraudulent and manipulative practices and protect investors and the public interest.

The agency asked about surveillance-sharing with a regulated bitcoin market of significant size, the relationship between bitcoin futures and spot price formation, and the proposed use of the MVIS Bitcoin OTC Index for net asset value. It also sought comment on the liquidity and transparency of the over-the-counter bitcoin market, arbitrage, alternative pricing methods, and the trust’s security, control and insurance arrangements.

Those questions explain why the withdrawal mattered institutionally without proving why BZX acted. A spot bitcoin trust needed more than a custody and pricing design; the exchange also had to demonstrate that listing rules could address manipulation and surveillance in markets outside the national-securities-exchange framework.

Market meaning, with limits

The immediate consequence was narrow: this specific proposed rule change could no longer produce an October 18 approval or disapproval order. The withdrawal did not bar BZX, VanEck, SolidX or another sponsor from making a different filing, and it did not change the operation of the Bitcoin network.

No price-response claim is warranted from the cited record. Bitcoin traded continuously across fragmented venues, while the SEC notice concerned a securities-exchange listing process. Without a defined venue, instrument, cutoff and comparison window, attributing a market move to the filing would overstate the evidence.

For the September 17, 2019 record, the defensible conclusion is procedural but consequential: a prominent attempt to place physically backed bitcoin exposure on a U.S. national securities exchange ended without the SEC ruling on its merits, leaving the agency’s market-integrity questions unresolved.
