London, Jan 19, 2026, 07:58 GMT — Premarket update.
- LSEG rose 98 pence, or 1.08%, ending the day at 9,184 pence.
- From Monday, Britain’s revised capital-raising rules will increase the prospectus requirement threshold.
- LSEG revealed another tranche of share repurchases, continuing its existing buyback programme.
London Stock Exchange Group shares are drawing attention as Britain adopts a lighter regulatory approach to capital raises, hoping to attract more deals. The stock finished Friday up 98 pence, or 1.08%, at 9,184 pence and is due to reopen at 0800 GMT on Monday. 1
The new Public Offers and Admissions to Trading rules kicked in Monday, cutting the deadline for companies to release a prospectus — the detailed disclosure investors review before buying shares. This shift aims to reinvigorate London’s equity market. Britain’s finance minister, Rachel Reeves, will spotlight the changes in a speech at the London Stock Exchange, Reuters reported, after new main market listings plunged to just nine last year. 2
The bar for follow-on equity issuance has climbed: firms now typically need a prospectus only if they issue shares equal to 75% of their current share capital in a 12-month span, a jump from the previous 20%, according to a Skadden note on the update. 3
LSEG added to its buyback program on Jan. 16, snapping up 108,969 shares. The purchase prices varied between 9,052 and 9,238 pence, with an average of 9,176.98 pence per share. These shares are set to be cancelled. 4
Investors are paying less attention to the rule changes and more to whether they actually lead to results. If equity raises and IPOs pick up pace, it could lift primary market and trading fees at the London Stock Exchange, even though LSEG’s core revenue still stems from data and post-trade services.
UK stocks kicked off the year with a boost. The FTSE 100 surged past the 10,000 mark on Jan. 5, finishing at 10,004.57, data from FTSE Russell shows. 5
Still, this regulatory change may not trigger a surge in deals. Lawyers warn that firms aiming at U.S. investors typically confront U.S.-style paperwork, and enthusiasm can evaporate quickly when politics enter the scene. On Monday, fresh tariff threats from President Donald Trump rattled European markets at the open. 6
Buybacks provide some backing, but LSEG shares tend to follow market and clearing activity forecasts. Despite rules aimed at smoothing fundraising, subdued trading or sharp “risk-off” swings can still push volumes down.
In the next session, traders will watch for signs that companies are prepared to meet the tougher 75% threshold, especially in secondary offerings where timing is crucial and delays can drive fees higher.
LSEG will release its preliminary results for the year ending Dec. 31, 2025, on Feb. 26. 7
