Imagine a 300-year-old institution, born from a London coffee house, now facing its greatest technological challenge yet. The London Stock Exchange Group (LSEG), once synonymous with trading floors and ringing bells, has transformed into a financial data powerhouse – and activist investor Elliott Management is betting it can survive the AI storm that’s already wiping billions from market valuations. But is this a savvy investment or a dangerous gamble?
The AI Disruption That’s Rattling Markets
For months, investors have been fleeing LSEG shares, wiping more than a third off the company’s value. The trigger? The launch of Anthropic’s Claude for Financial Services tool in July 2025, which demonstrated sophisticated financial modeling capabilities that could potentially replace traditional data analytics services. “Ever since Claude for Financial Services launched last summer, LSEG shares have been a lightning rod for market fears about AI disruption risk,” said Tom Mills, analyst at RBC Capital Markets.
This isn’t an isolated concern. Just last week, shares in major UK wealth managers including St James’s Place, AJ Bell, Quilter, and Aberdeen Group fell significantly after Altruist launched an AI platform that helps financial advisers personalize client investment strategies. Across the Atlantic, US brokerage shares like Charles Schwab and Morgan Stanley tumbled when fintech company Altruist introduced a tax-planning tool within its AI platform Hazel. The pattern is clear: any announcement of AI tools targeting financial services sends traditional players into a tailspin.
Elliott’s Contrarian Bet
While most investors are running scared, Elliott Management – the activist investor known for campaigns at BP and Anglo American – is taking a different approach. According to people familiar with the matter, Elliott has been talking to LSEG’s leadership, encouraging the group to boost share buybacks and close the profitability gap with peers like MSCI and CME Group. Their position points to a belief that LSEG should profit from the expected AI transformation in financial services, not falter.
LSEG CEO David Schwimmer has been resolute in his response to AI concerns, telling investors in October that “AI cannot replicate or replace our real-time data.” The company’s data and analytics division accounted for nearly half of its profits in the third quarter, and LSEG argues that its unique, proprietary data will protect it from AI’s advance. That data can be plugged into others’ models through partnerships with OpenAI, Anthropic, and software group Databricks, among others.
The Broader AI Investment Landscape
To understand why Elliott might be right – or dangerously wrong – we need to look at the broader AI investment landscape. Anthropic, the company behind Claude, has achieved what analysts call a “breakout moment,” growing from $1 billion in annualized revenue at the start of last year to over $9 billion by the end of 2025. The company guides investors that annualized revenue will exceed $30 billion by year-end, with a recent funding round valuing it at $350 billion.
What’s particularly telling is Anthropic’s strategy. Unlike consumer-focused AI products, Anthropic targets enterprises directly. “Anthropic is a well-run company with a simple capital structure that’s just working,” said Mike Paulus, billionaire former Andreessen Horowitz partner. “Sentiment has moved to the idea that enterprise is really where you get paid for AI.” This enterprise focus explains why financial services companies are particularly vulnerable – they’re exactly the customers Anthropic and similar companies are targeting.
The Diverging Tech Giants
The market’s reaction to AI investment tells another story. Since Q4 2025, the “Magnificent Seven” tech stocks have languished, with Nvidia faltering while Alphabet’s gains keep the group in positive territory. Microsoft, Amazon, and Alphabet shares sold off after announcing big investment budget increases, while Meta reported banner revenue growth and got a warmer market welcome. “The investment case for tech is no longer as straightforward,” said Seema Shah at Principal Asset Management. “The AI cycle appears to be entering a more mature phase: shifting from an environment that rewarded almost all tech exposures to one where AI advancement more clearly differentiates adaptive, resilient models from those that are easily automated.”
This maturation means investors are becoming more discerning about AI winners and losers. There’s increasing scrutiny over returns on AI spending, and companies that can’t demonstrate clear value from their AI investments are being punished. For LSEG, this creates both risk and opportunity – if they can leverage AI effectively, they could emerge stronger; if they can’t, they risk becoming another casualty.
The Human Factor in AI Adoption
Perhaps the most insightful perspective comes from how we think about AI in the workplace. Sangeet Paul Choudary, an expert on business innovation and senior fellow at Berkeley’s Haas School of Business, argues that we’re thinking about AI all wrong. “There’s been too much framing of AI as an alternative to humans, and hence job losses and all of those aspects,” he said. “And there’s too little framing of AI just as technology, and how do you leverage it, just as you would leverage any technology.”
This perspective is crucial for understanding LSEG’s position. Rather than viewing AI as a replacement for their data services, they need to see it as technology to be leveraged. “As the AI improves, and as our ability to adopt AI constantly improves, what machines do and what humans do is constantly changing,” Choudary added. “As humans, we have to constantly re-evaluate and redesign our work in response to what the machine can do better now.”
LSEG’s Path Forward
So what does this mean for LSEG and Elliott’s investment? The company has several options. According to Ian White, senior analyst at Autonomous Research, LSEG has the balance sheet space to consider buying back �3.5 billion more in shares, which could help appease Elliott. Cuts in areas such as “third party costs, IT expenses, consultant support” could improve profitability. Another option could be selling its roughly �10bn stake in Tradeweb, an electronic debt trading platform that has grown rapidly in recent years.
Ben Needham, UK quality portfolio manager at Ninety One, a top 20 LSEG shareholder, sees opportunity in the current valuation. The company “is now quality at a very good price and we’ve been leaning in heavily [buying] in the last few weeks,” he said. He added that data and software companies “have been sold off indiscriminately” in the face of AI fears.
But not everyone is convinced. Ian White noted that the appeal of using LSEG for customer-facing AI is being questioned: The UK company is now “not as broad in terms of relevance and applicability as [it] thought [it was] going to be.” He added that the AI threat is more pronounced for LSEG than other exchange groups such as Euronext and Deutsche Boerse, which make more of their money from traditional exchange businesses, rather than data and analytics.
The Bigger Picture
What’s happening with LSEG is a microcosm of a larger trend. As Jim Reid at Deutsche Bank warned, “if more of the Mag 7 are caught off guard in the disruption, the spillover may have profound implications for the macroeconomy.” We’re seeing the early stages of AI fundamentally reshaping industries, with financial services at the forefront.
The question isn’t whether AI will disrupt financial services – it already is. The question is which companies will adapt and thrive, and which will become casualties. Elliott’s bet on LSEG represents a belief that this 300-year-old institution can transform once again. But as one adviser familiar with Elliott’s tactics cautioned: “They kick people hard.” Whether that kicking pushes LSEG toward innovation or breakdown remains to be seen.
What’s clear is that we’re witnessing a pivotal moment in the intersection of finance and technology. The companies that survive won’t be those that resist AI, but those that learn to leverage it effectively. As the market’s reaction to Anthropic’s tools shows, the disruption is already here – the only question is who will be left standing when the dust settles.
