Citigroup launches a blockchain-based marketplace intended to let investors buy and sell exposure to shares of private companies using tokenized depositary receipts. Multiple reports say the platform is designed to broaden access to private markets and improve liquidity for shareholders of companies that remain unlisted for longer periods, often relying on fragmented secondary trading. According to the coverage, Citi applies its established depositary receipt framework to private-company equity and issues tokenized depositary receipts backed by private market shares. The service is initially aimed at foreign investors, with the stated goal of making it easier for issuers to reach investors and for investors to access private market opportunities. One report describes the offering, called “Digital Depositary Receipts,” as built on blockchain infrastructure operated by SIX, a Swiss financial market operator and digital central securities depository. Under Citi’s model, Citi functions as both issuer and custodian of the digital receipts, handling issuance, settlement and safekeeping. The reports frame the launch as part of wider industry interest in tokenized assets and tokenized financial infrastructure.
