Nearly a decade after raising $100 million, Prometheum has finally executed its first crypto trades, launching Ethereum (ETH) custody and trading. The milestone, however, arrives just as the specialized regulatory license the company fought to obtain has been rendered obsolete by a broader SEC policy shift.
Founded roughly ten years ago, Prometheum in 2023 became the first firm to secure a special purpose broker-dealer license from both the SEC and FINRA, a designation that was supposed to give it an exclusive legal pathway to custody and trade digital asset securities. Co-CEO Aaron Kaplan had long argued that the SEC’s framework offered a clear compliance route, a stance that drew industry mockery—at one point critics likened the platform to a “vending machine with no snacks” due to its lack of volume.
The landscape has changed dramatically. Following Gary Gensler’s departure as SEC chair, the agency dropped its lawsuit against Coinbase and withdrew most crypto-related enforcement actions. More critically, revised SEC guidance now allows any traditional broker-dealer to custody digital asset securities under standard customer protection rules, eliminating the need for Prometheum’s hard-won license.
Kaplan remains optimistic, emphasizing that the platform can now integrate crypto into hundreds of millions of brokerage and advisory accounts, bypassing ETF management fees and “a layer of abstraction.” The firm plans to add more digital assets soon. However, the regulatory moat that underpinned its business model has evaporated, underscoring how quickly competitive advantages can vanish in the evolving U.S. crypto policy environment.
