Tokenized securities at $24B as Prometheum expands

Prometheum has launched new infrastructure allowing broker-dealers and RIAs to offer tokenized securities through traditional brokerage accounts.

Prometheum launched new infrastructure on May 25 allowing broker-dealers and registered investment advisers to offer tokenized securities and crypto assets through traditional brokerage accounts. The company positions the launch as a bridge between blockchain-based securities and the conventional financial system.

“Crypto has solved tokenization, but it hasn’t solved distribution,” said Aaron Kaplan, co-founder and co-CEO of Prometheum. “There are tens of billions of dollars of tokenized securities already issued on blockchain rails, but almost no mainstream distribution channel to reach investors at scale.”

Why the distribution problem matters more than issuance

More than $24 billion in securities products have already been issued on blockchain networks according to RWA.xyz data. Crypto.news has tracked the rapid growth of tokenised Treasuries from $380 million in 2023 to $13.4 billion by April 2026, with tokenised equities emerging as the fastest-growing sub-sector.

The challenge Kaplan identifies is structural. Issuers can now tokenize securities relatively easily, but reaching mainstream investors requires access to regulated brokerage accounts, settlement infrastructure, and investor onboarding that most blockchain-native platforms do not provide.

Prometheum’s network of SEC-registered and FINRA-member broker-dealers provides correspondent clearing, custody, execution, and recordkeeping for third-party broker-dealers, enabling their clients to access on-chain securities within existing legal frameworks.

What Prometheum’s infrastructure adds to the tokenization market

Crypto.news has reported on BlackRock filing a second tokenised fund application with the SEC through Securitize, signalling institutional demand for regulated tokenization infrastructure is growing from both issuer and distribution sides. The Prometheum approach targets the distribution gap that well-resourced issuers still face, since retail brokerage access to on-chain securities remains limited to a small number of registered platforms.

Crypto.news has also covered Securitize’s plans to launch natively tokenized public stocks with full on-chain settlement. Whether Wall Street brokerage firms adopt Prometheum’s infrastructure will depend partly on whether the Clarity Act’s passage reduces regulatory uncertainty enough to justify the compliance investment.
