London Stock Exchange Builds AI-Native 24/5 Trading Venue With On-Chain Settlement Path

The London Stock Exchange (LSEG) has announced LSE 24, a new 24/5 trading venue specifically engineered for AI agent-based trading rather than human-scale operations. Unlike US exchanges that are simply extending existing hours, LSE 24 is a greenfield build featuring native machine-to-machine connectivity and a hybrid order-matching architecture using both Central Limit Order Books and Request-for-Quote mechanisms. This venue is designed to accommodate autonomous AI agents that reason and execute trades without human oversight, addressing the friction these systems face with traditional broker-centric infrastructure. A critical component of this initiative is its planned integration with the LSEG Digital Securities Depository, an on-chain settlement platform developed under the UK's Digital Securities Sandbox. By combining AI-native connectivity with blockchain-based settlement, LSEG aims to solve the liquidity and structural challenges inherent in overnight trading. This development marks a significant shift toward institutionalizing autonomous market participation within a regulated framework. The move highlights the growing necessity for financial infrastructure to evolve alongside the transition from fixed-rule algorithms to agentic AI systems.
