- London traded in regular hours, with the London Stock Exchange open from 08:00 to 16:30 BST. Its next scheduled holiday is May 25.

London Stock Exchange Group shares slipped on Monday, lagging the FTSE 100, as investors looked at the company’s recent growth upgrade while the UK market stayed cautious and activists circled European exchange groups again.
LSEG traded at 9,118p to sell and 9,122p to buy on Hargreaves Lansdown data, off 14p or 0.15% on delayed prices. The FTSE 100 gained 62.48 points, up 0.61% at 10,257.85.
Timing is key. London was trading a normal session, running from 08:00 to 16:30 BST, with the next exchange holiday not until May 25.
LSEG shares are moving without a new company filing. The stock is still reacting to its April 23 first-quarter update. Back then, the group said total income excluding recoveries rose 9.8% on an organic constant-currency basis, taking out currency impacts and some deal noise. Markets revenue climbed 15.5%, on stronger trading volumes. Data & Analytics was up 5.1%.
Chief Executive David Schwimmer called it a “great start to 2026” and said LSEG’s trading venues were “critical sources of liquidity.” Liquidity, he said, is how easily assets can be bought or sold without causing large price swings. LSEG said it expects 2026 total income growth to come in at the upper half of its 6.5%-7.5% target range. LSEG
Data is still driving the stock. LSEG reported over 150 customers have either hooked up to or are getting started with its Model Context Protocol, or MCP, server. The MCP gives AI systems access to outside data with context and accuracy checks.
Will Howlett, a financials analyst at Quilter Cheviot, said the first-quarter beat and higher guidance “should help ease concerns” about growth holding up. Howlett also said LSEG has been caught up in the market’s back-and-forth on AI’s impact for data providers. Quilter
This debate keeps the shares under scrutiny. Reuters said in February that Elliott Management had taken a position in LSEG, pressing the group on buybacks, performance, and margins against peers. LSEG said then it maintained an “active and open dialogue” with investors. Reuters
Peer action gave fresh news on Monday. Deutsche Börse moved higher after hedge fund TCI said it holds a 5.15% stake. Reuters said TCI is not planning to be an activist, quoting a source. Deutsche Börse said it welcomes TCI’s involvement.
UK markets were choppy. Reuters said the FTSE 250 slid 0.59% as inflation fears and doubt around Prime Minister Keir Starmer pulled sentiment lower. The FTSE 100 traded up earlier in the day. Oil prices stayed high and shipping through the Strait of Hormuz remained tight, keeping inflation risks on the table.
LSEG’s data and capital-markets business is seeing a clearer picture thanks to a better M&A environment. UK M&A is at $192 billion so far in 2026, which is more than three times higher than this point in 2025, LSEG numbers shared by Reuters show. Dominic Ross, a partner at Clifford Chance, called the UK a “tried and tested market.” Reuters
But the risk side is still there. If inflation from oil holds bond yields up, stock valuations might keep feeling the heat and IPOs could stay uneven. LSEG still needs to show AI can drive paid demand for its data instead of hurting its pricing muscle. That debate is still hanging over the shares.
