LSE to launch overnight venue as exchanges race for 24-hour trading

The London Stock Exchange will open a near-continuous trading venue by early 2027, joining a global push by exchanges to extend trading beyond traditional hours.

The London Stock Exchange plans to launch LSE 24, a near-continuous trading venue operating from 17:00 to 07:50 on weekdays, joining a global race among exchanges to extend the trading day.

"This launch marks an important step in the evolution of our markets, offering clients greater flexibility beyond traditional hours," Julia Hoggett, chief executive of the London Stock Exchange, said.

The venue will run Monday to Friday with a 30-minute pause each evening for end-of-day processing. It is designed to support digital, algorithmic and so-called agentic trading, where AI agents execute orders. Exchange-traded products will be the first asset class to launch in the first half of 2027, subject to regulatory approval, with equities to follow. Client testing is scheduled to begin by the end of 2026.

The move positions the LSE against a wave of extended-hours initiatives across global markets. The New York Stock Exchange has won preliminary regulatory approval for a 22-hour trading day, while Nasdaq has filed with the Securities and Exchange Commission for a 23-hour session across five days, targeting a launch in the second half of 2026. Cboe Global Markets is pursuing similar plans. Foreign investors hold roughly $17 trillion of US stocks, driving demand for around-the-clock access.

Overnight Liquidity Concerns Persist

Not everyone is convinced. Some on Wall Street have warned that overnight trading can be thinly traded and potentially destabilising, raising questions about liquidity depth during off-peak hours. The concern echoes debates that accompanied the rise of after-hours trading in US markets over the past decade, when wider bid-ask spreads and lower volumes created risks for retail participants.

For the LSE, the initiative is as much about competitive positioning as it is about revenue. London has faced growing pressure from rival financial centres and alternative trading platforms, including cryptocurrency exchanges that operate 24/7. By offering near-continuous access to listed products, the exchange aims to retain and attract international investors who increasingly expect round-the-clock market access.

Digital Infrastructure as Competitive Edge

The venue will draw on LSEG's broader digital strategy. The group has been investing in its data and analytics business alongside its traditional exchange operations, seeking to diversify revenue beyond listing and trading fees. The Digital Securities Depository, part of that push, is designed to support tokenised securities and digital asset settlement.

The LSE's Main Market will continue to trade during its existing hours of 08:00 to 16:30, with LSE 24 operating as a separate venue. The exchange's digital markets infrastructure will underpin the new platform, which is built to handle high-frequency and algorithmic order flow.

The shift toward near-continuous trading represents one of the most significant structural changes to equity market infrastructure in decades. Traditional exchanges have long operated on a model of fixed opening and closing auctions with a defined trading day, a structure that dates back to physical trading floors. The rise of electronic trading, cross-border investment and digital assets has eroded the rationale for those boundaries.

For institutional investors in Asia and the Middle East, overnight access to London-listed products removes a barrier to participation. The ability to trade European equities during Asian business hours could deepen liquidity pools and narrow spreads during what are currently low-activity periods.
