Republican lawmakers on the U.S. House Financial Services Committee, led by Chairman Patrick McHenry (R-NC), have formally requested documents and communications from the Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA) concerning the regulator's approval of Prometheum as the first and only special purpose broker-dealer (SPBD) for digital assets. In letters sent on August 9, the lawmakers expressed serious concerns about the timing, transparency, and national security implications of the decision, noting that Prometheum has no customers, no operating history, and troubling links to the Chinese government.
Background of the Special Purpose Broker-Dealer Approval
The SEC created the SPBD category in 2020 to allow firms to custody digital asset securities under federal securities laws. In May 2023, FINRA approved Prometheum Ember Capital LLC as the first SPBD. However, multiple other firms have applied for the same designation and remain unapproved. The lawmakers questioned why FINRA would choose to approve a company with “no operating history and no track record of serving customers over all the applications that it has received.”
In their letter to SEC Chair Gary Gensler, the lawmakers demanded the production of “all documents and communications, between and among SEC employees, related or referring to Prometheum’s application to become a special purpose broker-dealer,” by 5:00 pm on August 22, 2023. Similar requests were made to FINRA President and CEO Robert Cook.
Key Concerns Raised by Lawmakers
Timing and Legislative Context: The approval came just as the Committee was deliberating on legislation to create a comprehensive regulatory framework for digital assets. The Financial Innovation and Technology for the 21st Century Act was introduced on June 2, 2023. Lawmakers suspect the approval was intentionally timed to demonstrate that existing regulations are sufficient, thereby undermining the need for new legislation.
Lack of Operational Readiness: Prometheum has not served a single customer. It has refused to publicly disclose which digital asset securities its alternative trading system (ATS) would support. Moreover, it currently cannot perform clearing or settlement services—essential functions for an ATS. The lawmakers stressed it is “unclear why FINRA would have chosen to approve a firm with no operating history” over other applicants.
National Security Ties to China: The lawmakers highlighted concerns about Prometheum's ties to the Chinese government. Congressman Scott Fitzgerald (R-WI) tweeted: “It’s concerning that SEC Chair Gensler’s first and only approval of a special purpose broker-dealer for digital assets was done for a company with strong ties to the CCP.” Representative Ritchie Torres (D-NY) had previously called for an investigation into the SPBD license granted to Prometheum by the SEC. The lawmakers view these ties as a potential data privacy and national security risk.
Implications for the Crypto Industry
The investigation adds to growing scrutiny of SEC and FINRA's handling of digital asset regulation. Critics argue that the approval process lacks transparency and may be politically motivated. If the regulators cannot justify their decision, the episode could erode trust in the U.S. regulatory framework for digital assets and delay innovation.
Prometheum has not publicly responded to the investigation. Meanwhile, the SEC and FINRA have declined to comment on the lawmakers' letters. Industry observers expect the probe to cast a long shadow over future SPBD approvals and to intensify partisan debates on Capitol Hill regarding the appropriate oversight of cryptocurrency markets.
As the August 22 deadline approaches, market participants await the released documents to shed light on what truly drove the approval of a company with no customers and opaque foreign connections.
