A year ago, the London Stock Exchange Group was the market’s favorite cautionary tale about what AI might do to legacy data businesses. Now it’s trying on a different outfit: growth story.
LSEG’s shares have climbed 27% since activist investor Elliott Management revealed its stake earlier in 2026, a recovery that speaks to a broader recalibration of how Wall Street thinks about AI’s impact on financial data providers. The company that saw its stock tumble as much as 35% over the year leading up to February 2026 is now posting organic revenue growth numbers that would make its critics pause.
The numbers behind the narrative shift
In the first quarter of 2026, LSEG’s Data & Analytics segment delivered organic revenue growth of 5.1%. Within that segment, Workflows grew 2.9% while Analytics posted a 5.2% increase. Total income, excluding recoveries, rose 9.8% on an organic constant-currency basis, beating prior expectations.
For the full year, LSEG has guided for organic constant-currency total income growth of 6.5-7.5%.
