The FTSE 100 closed lower on Tuesday as a rally in mining stocks was offset by hefty falls in software, data analytics and advertising companies amid perceived AI threats.

The FTSE 100 index closed down 26.97 points, or 0.3%, at 10,314.59.

The FTSE 250 ended down 135.68 points, or 0.6%, at 23,290.37, and the AIM All-Share closed up 3.99 points, 0.5%, at 818.33.

On the FTSE 100, Relx slid 14%, London Stock Exchange Group tumbled 13%, Experian slumped 8.3%, Sage Group declined 6.5% and Pearson 7.7%.

The sharp falls came after US artificial intelligence firm Anthropic released new ‘agentic AI’ tools for corporate legal teams, including a legal plug-in for its Claude generative AI chatbot.

The US AI company said the tool can automate legal work such as reviewing contracts, triaging non-disclosure agreements, composing briefings and providing templated responses.

The roll-out renewed fears that AI will threaten existing business models, hitting sales and growth.

Relx owns LexisNexis, a provider of information and analytics to law firms, while London Stock Exchange is a financial data provider.

Experian is a credit checker, Pearson a provider of educational content and assessments while Sage sells accountancy software.

PayPal sank 19% after naming a new chief executive as fourth quarter results and guidance missed forecasts.

The San Jose, California-based financial transaction processing services company said performance had been “solid”, but execution “has not been where it needs to be, particularly in branded checkout”.

As a result, PayPal appointed Enrique Lores as president and chief executive, effective March 1.

Mr Lores, who has served on the PayPal board for nearly five years and as chairman since July 2024, succeeds Alex Chriss.
