Citi and Swiss firm SIX Digital Exchange (SDX) have announced a partnership to launch a blockchain-based platform for tokenizing late-stage private shares, targeting the pre-IPO market. The initiative is scheduled to begin in the third quarter of 2025 and aims to provide institutional investors with on-chain access to trade shares of high-growth, venture-backed private companies. This development represents a notable advancement in the integration of private equity with blockchain technology. Meanwhile, the Arbitrum blockchain stack continues to gain traction among crypto projects, with companies like Cred Protocol and Ethena expanding their use of Arbitrum for capital formation and decentralized finance applications.
