The London Stock Exchange Group (LSEG) has introduced its Digital Markets Infrastructure (DMI), a blockchain-powered platform for private funds, marking the first such launch by a major global exchange

Developed with Microsoft and hosted on Azure, DMI is designed to manage the full lifecycle of digital assets – from issuance and tokenization to post-trade settlement – while bridging traditional finance with distributed ledger technology (DLT).

Private funds are the initial asset class supported, with expansion to other asset classes planned

Through Workspace, general partners can now connect directly with professional investors

Early participants include MembersCap, a capital management firm that executed the platform’s first transaction, and Archax, a UK-regulated crypto exchange, acting as a nominee for the Cardano Foundation.

Microsoft hailed the platform as a milestone in its strategic partnership with LSEG, while LSEG executives stressed the overdue modernization of private market processes

The broader goal is to enhance efficiency, transparency, and investor access in private markets.

Industry voices, including JPMorgan’s Kinexys and Chainlink Labs, noted the move could accelerate convergence between traditional finance and decentralized finance (DeFi).
