London Stock Exchange's LSE 24 signals a bet on digital, AI-driven markets: TD Cowen

The London Stock Exchange will launch LSE 24, a new 24/5 trading venue built to support digital, algorithmic and agent-based trading, the exchange said Tuesday.

The venue will run from 17:00 to 07:50 Monday through Friday, with a 30-minute pause each evening for end-of-day processing, operating separately from the exchange's Main Market, which keeps its existing 08:00 to 16:30 hours.

LSE 24 will be available for client testing by the end of 2026, with exchange-traded products launching as the first asset class in the first half of 2027, subject to regulatory approval. The exchange intends to expand the venue into equities as a next step, drawing on central limit order book and request-for-quote functionality to support price transparency and on-demand liquidity.

"The launch of LSE 24 marks an important step in the evolution of our markets, providing clients with greater flexibility beyond traditional trading hours," said Julia Hoggett, CEO of LSE plc and head of digital and securities markets at LSEG.

The infrastructure play beneath the hours

The extended hours are the headline, but TD Cowen argued the more consequential piece is what the venue signals about where market plumbing is heading.

LSE 24 will draw on LSEG's forthcoming Digital Securities Depository, which the group is developing to digitize issuance, settlement and asset servicing, and which LSEG intends to expand across asset classes over time, analysts Lance Vitanza and Jonnathan Navarrete wrote in a note shared with The Block.

The announcement's emphasis on agent-based trading workflows points to a broader shift in which execution and market access grow more software-driven, particularly during extended hours when human participation runs lower, according to TD Cowen.

The analysts cautioned that the release does not suggest LSE 24 will replace existing market structures or move conventional securities trading onto blockchain-based infrastructure. Their read is that the venue is a step toward greater automation and increasingly digital post-trade infrastructure rather than a wholesale rebuild.

A global race for the overnight session

The move tracks a wider push among exchanges toward round-the-clock trading. In the United States, the New York Stock Exchange has won preliminary regulatory approval for a 22-hour trading day.

Some on Wall Street have warned that overnight sessions can be thinly traded and potentially destabilizing.

ETPs are the starting point given London's position as a leading international hub for the products, according to the exchange.
