Activist Investor Elliott Expands Stake in LSEG
The activist investor Elliott Management has acquired a "significant" stake in the London Stock Exchange Group (LSEG) and is actively engaging with the company to enhance its performance during a period marked by reduced listings and concerns over artificial intelligence disruption.
The precise size of Elliott’s shareholding in LSEG remains undisclosed. According to the Financial Times, which initially reported the stake, Elliott has been in discussions with LSEG to support efforts aimed at improving the company’s operations, encouraging consideration of a new share buyback program, and narrowing the competitive gap with rival firms.
Shares of LSEG rose by as much as 6% during early trading on Wednesday before retreating slightly.
LSEG’s Business Shift and Market Performance
LSEG is primarily recognized for operating the London Stock Exchange but has recently diversified away from traditional stock market activities. Following its 2020 acquisition of the financial data provider Refinitiv, nearly half of the group’s revenues now stem from its data and analytics division.
Over the past year, LSEG’s share price has experienced a steady decline amid investor concerns that its revenue streams may be pressured by AI-driven disruption amid intensifying competition.
Specifically, LSEG’s shares have fallen by more than 35% in the last 12 months. Earlier this month, the shares dropped 13% following the US Securities and Exchange Commission’s approval of a generative AI tool designed for use by companies’ legal departments, which investors feared could negatively impact LSEG’s data business.
Elliott’s Broader Activist Campaigns
LSEG is the latest target of Elliott Management’s activist investment strategy. Previously, Elliott acquired a stake in BP valued at nearly £3.8 billion, representing 5% of BP’s shares, in early 2025, making it the oil company’s third-largest shareholder.
BP’s chief executive, Murray Auchincloss, was dismissed after less than two years in the role, following pressure from Elliott. The hedge fund also led a successful campaign against BP’s board earlier in 2025.
Elliott typically invests in companies it believes have underperformed due to mismanagement, advocating for changes aimed at enhancing market value. The fund has previously engaged with companies such as BT Group and the housebuilder Taylor Wimpey.
Known as a prominent New York hedge fund, Elliott also owns the combined Barnes & Noble and Waterstones bookstore chains and is reportedly considering a listing preference for London over New York, which would be viewed as a positive development for the UK stock market.
Market Context and Future Outlook
There was an increase in the rate of business listings during the second half of 2025, although concerns persist that takeovers and delistings have reduced the number of public companies in the UK.
Both LSEG and Elliott declined to comment on the ongoing discussions.
