London, May 13, 2026, 12:04 BST
- LSEG traded around 9,280p, down about 0.7%, giving back part of Tuesday’s 3.64% rally even as it announced a Google Gemini Enterprise data connector.
- The move looked less like a rejection of the AI deal and more like profit-taking mixed with a rough UK rates tape, after 10-year gilt yields hit their highest level since 2008.
- Bulls point to Q1 growth, buybacks and AI distribution; bears point to valuation, proof of AI monetisation, and a still-volatile UK macro backdrop.
London Stock Exchange Group slipped in London trading, sitting near 9,280p at midday, down roughly 0.7%. That came after a sharp Tuesday move higher, when the stock closed at 9,348p, up 3.64%. The odd part: the drop landed on the same morning LSEG announced that its financial data and analytics would be brought into Google Cloud’s Gemini Enterprise through a new connector.
So the price action was not a clean “bad news” move. It looked more like a stock giving back part of a rally while investors marked down UK-listed financial assets against a harder rates backdrop. UK government bond yields, known as gilts, have jumped as politics and inflation worries raised the cost of borrowing; Reuters reported that the 10-year yield touched 5.13%, the highest since 2008. Higher yields make future earnings worth less today, which matters for a high-quality but highly valued market infrastructure name like LSEG. Reuters
That is why the chart slipped despite the Google news. The company story is moving in the right strategic direction, but the market was also pricing in a tougher discount rate. In plain English, investors may still like the business, but they were less willing today to pay the same multiple for its future cash flows.
The Google deal matters because it goes straight at the question hanging over LSEG: whether artificial intelligence weakens the old desktop-and-data model, or makes trusted financial data more valuable. The new connector uses Model Context Protocol, or MCP, which is basically a controlled pipe that lets AI agents pull licensed data into the tools where clients work. Emily Prince, LSEG’s group head of enterprise AI, said financial institutions want “to move faster with AI.” MarketScreener
This is not a one-off partnership. In its April trading update, LSEG said clients were already accessing its data through Anthropic, Microsoft, OpenAI, Databricks and Snowflake, and that 90 customers were connected to its MCP server while 64 more were onboarding. The point is distribution. LSEG wants its data to follow users into AI workflows, not wait for users to come back to a terminal.
The last hard numbers gave bulls plenty to work with. LSEG reported first-quarter total income growth of 9.8% on an organic constant-currency basis, meaning after stripping out currency effects and other distortions. Markets revenue rose 15.5%, Data & Analytics grew 5.1%, subscriptions rose 6.3%, and the company said full-year revenue growth should land in the upper half of its 6.5% to 7.5% range. Chief Executive David Schwimmer called it a “great start to 2026.” LSEG
Capital returns add another prop. LSEG completed £1.1 billion of buybacks in the first quarter and remains on track for a £3 billion programme by February 2027. It also guided for an EBITDA margin gain of 80 to 100 basis points, or 0.8 to 1.0 percentage points, this year. That combination — growth, margin lift, buybacks — is why the stock can rally hard when the market mood allows it.
The bull case is simple enough. LSEG sits at the intersection of trading, benchmarks, risk data and workflow software, and bouts of volatility can help parts of the business. The official analyst consensus published by LSEG on May 8 showed 16 Buy ratings, no Holds or Sells, and an average target price of 12,131p, against a 9,186p close on May 7. Reuters also quoted Will Howlett of Quilter Cheviot as saying the Q1 beat and stronger guidance should ease concerns about the durability of growth.
The bear case is not weak, though. LSEG trades at about 35.5 times estimated 2026 earnings, using MarketScreener’s data; price-to-earnings, or P/E, is the share price divided by expected profit per share. At that level, investors do not forgive much. AI headlines need to turn into paid usage, higher retention or better pricing power, not just more integrations.
The peer tape also points to a broader exchange-and-data wobble, not just an LSEG issue. Deutsche Börse and Euronext were both lower, while Nasdaq traded higher, leaving LSEG somewhere in the middle of a mixed global market infrastructure group. That soft European read-through fits the day: solid company news, weaker macro tape.
Prediction-market signals were not the driver, but they help frame the risk. Polymarket showed Andy Burnham and Wes Streeting both at 24% in its “Next UK prime minister in 2026” market, while a separate market put the probability of a Bank of England rate hike in 2026 at 65%. Those odds are not official forecasts, and the rate market was thinner, but they show traders treating UK policy risk as live rather than settled. Polymarket
For LSEG, that cuts both ways. More market stress can lift trading and risk-management demand, as seen in the strong Q1 Markets result. But persistent high rates can weigh on valuation, especially for a stock that the market already prices as a compounder.
Today’s move, then, is a reality check rather than a broken thesis. The Google tie-up strengthens the AI distribution story. The selloff says investors still want proof — and, in this tape, they want it while UK yields, politics and valuation are all pulling at the same share price.
