LSEG sheds ‘AI loser’ tag as shares rebound 27%
TL;DR:
- London Stock Exchange Group shares have risen 27% since activist Elliott Management’s stake emerged, as investors reassess whether AI threatens its data business.
- A February selloff wiped nearly 13% off the stock in a day on fears that large language models could undercut financial-data providers.
- LSEG’s pitch — including a data server that feeds proprietary datasets to third-party AI agents — is winning analysts round, though some caution remains.
For a flagship UK firm, the AI question cut both ways. In February, London Stock Exchange Group lost almost 13% in a single session as investors fretted that models like Anthropic’s Claude would erode demand for paid financial data. Four months on, the company is steadily convincing the market it can be an AI beneficiary rather than a casualty.
From threat to growth story
The turnaround coincided with US activist Elliott Management building what it called a “significant stake” from early February; the shares are up 27% since, though still 23% below their 2025 peak. UBS recently removed LSEG from a basket of firms it judged vulnerable to disruption, while still calling it a “show me” story on AI revenue.
The clearest evidence sits in LSEG’s Model Context Protocol server, which pipes some proprietary datasets to external AI agents and large language models. At its Q1 update the company reported more than 90 customers connected and 60 in the pipeline, with total income up 9.8% — its strongest quarterly performance in over five years. “They are part of the AI ecosystem rather than competing against it,” noted BofA’s Hubert Lam.
Not everyone is convinced. Blue Whale’s Stephen Yiu said the disruption risk is far from minimal, and a long-running fight over UK plans for an equities “tape” could still threaten the data business. The episode echoes the wider AI-driven selloff in data and software stocks earlier this year, and sits within the FCA’s lighter-touch approach to AI in financial services.
Looking forward
With 90% of covering analysts rating the stock a buy and a £3bn ($4bn) buyback under way, LSEG has bought itself credibility and time. The harder task is converting MCP usage into paid revenue — the difference between an AI growth story investors believe and one they merely tolerate.
