The firm remains confident even as the market flips from seeing it as an AI winner to fearing its profit margin will implode

As the FTSE 100 index bobs along close to all-time highs, it is easy to miss the quiet share price crash in one corner of the market. It’s got a name – the “Claude crash”, referencing the plug-in legal products added by the AI firm Anthropic to its Claude Cowork office assistant.

This launch, or so you would think from the panicked stock market reaction in the past few weeks, marks the moment when the AI revolution rips chunks out of some of the UK’s biggest public companies – those in the dull but successful “data” game, including Relx, the London Stock Exchange Group, Experian, Sage and Informa.
