The London Stock Exchange LON:LSEG is refusing to sleep. Today it announced LSE 24, a new near-continuous trading venue operating from Monday to Friday. The platform will run from 17:00 to 07:50 with a brief 30-minute pause for end-of-day processes, leaving the Main Market’s traditional 08:00-16:30 hours untouched.

The goal is to accommodate the next generation of digital, algorithmic and “agentic” trading while preserving the resilience of core session liquidity.

LSE 24 builds on LSEG’s established infrastructure. It will initially focus on Exchange Traded Products when it launches in the first half of 2027, following client testing by the end of 2026.

ETPs make sense as a starting point: London is already a global hub for such products, and demand for efficient, round-the-world exposure is strong.

The venue will blend central limit order book and request-for-quote features for transparency and on-demand liquidity, with plans to expand into equities later. Subject to regulatory approval, it will also connect to LSEG’s forthcoming Digital Securities Depository, which aims to modernise issuance, settlement and asset servicing.

More than just an extension of trading hours for LSEG

This is more than an extension of trading hours. Julia Hoggett, CEO of LSE plc and head of digital and securities markets at LSEG, frames it as an evolution towards “more digital, connected global markets”. LSE 24 is explicitly designed for automated workflows and agent-based trading, offering secure native connectivity to market data, order management and execution.

In an era of AI-driven strategies, the ability to trade outside traditional windows while maintaining regulated market controls could prove attractive to global participants managing risk across time zones.

LSE’s response to competitive pressure

The move reflects competitive pressure. Asian and US markets have long offered extended or near-24-hour access in certain instruments. European exchanges have been slower, but the rise of algorithmic and high-frequency trading, coupled with the growing role of passive and systematic strategies, makes round-the-clock capability almost inevitable for a venue that wants to stay relevant.

London’s post-Brexit challenge has been to reinforce its status as an international financial centre. Extending effective trading availability is one way to compete for order flow that might otherwise gravitate elsewhere.

Success is far from guaranteed. Extended-hours sessions often suffer from thinner liquidity, wider spreads and greater volatility. By starting with ETPs rather than core equities, LSEG is being pragmatic: these products are typically more liquid and easier to trade electronically. Yet attracting meaningful volume outside traditional hours will require critical mass.

The integration with future digital settlement infrastructure is a smart hedge, potentially lowering frictions and broadening participation, but digitisation projects have a habit of slipping timelines.

Good news for LSEG shareholders?

For LSEG shareholders, the announcement signals continued investment in infrastructure and technology, areas where the group has historically excelled. If LSE 24 captures even a modest share of growing global algorithmic flows and reinforces London’s position in ETPs, it could enhance the exchange’s long-term franchise value.

The real test will come in execution: delivering reliable performance, robust controls and genuine new liquidity rather than merely shifting existing activity.

London has long prided itself on innovation within a stable regulatory framework. LSE 24 represents a bet that the City can blend tradition with the demands of a 24/7 digital world. In an industry where time is quite literally money, giving clients more of it may prove a shrewd move, provided the liquidity follows.
