Meanwhile Rightmove led the index\u2019s fallers, with a slump of over six per cent to 444.40. Sage was down over three per cent to 842.53p.<\/p>\n<p>Despite the losses, the FTSE 100 still managed to pull ahead rising by 1.2 per cent in later trading and breaking the 10,400 mark. This was mainly led by a major nine per cent surge from Beazley on its blockbuster takeover and an eight per cent rally from DCC after an upbeat earnings update.<\/p>\n<p>Information-based analytics firm Relx \u2013 which is in the top 20 of the City\u2019s most valuable blue-chips \u2013 had over \u00a36bn wiped from its market value with a fall of over 16 per cent on Tuesday. The firm managed to eke out a gain in Wednesday\u2019s early trading, up a modest 0.3 per cent.<\/p>\n<p>\u201cRELX has a large presence in the legal space and was in the teeth of the resulting storm. It was among several names to endure double-digit declines as investors weighed the wider implications. <\/p>\n<p>\u201cTo what extent AI can disintermediate traditional data analytics and software firms is not yet clear, but a lot of investors weren\u2019t sticking around to find out,\u201d said Dan Coatsworth, head of markets at <a href=\"https:\/\/www.ajbell.co.uk\/?utm_source=google&amp;utm_medium=cpc&amp;utm_campaign=AJBell_Croud_UK_Google_Brand&amp;gclsrc=aw.ds&amp;gad_source=1&amp;gad_campaignid=23068550325&amp;gbraid=0AAAAAD8knHWzgQAflu8NMf2si67D_YN-2&amp;gclid=Cj0KCQiA-YvMBhDtARIsAHZuUzIL_S3nIVAl6dNnBMg7giAVliJuG5eVwh3ZAOUfzA2booyc1w4fL9QaAuIfEALw_wcB\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">AJ Bell<\/a>.<\/p>\n<p>Coatsworth said \u201cconcerningly\u201d for the day\u2019s fallers there was \u201clittle sign of a share price recovery today, with bargain hunters not tempted to step in.\u201d<\/p>\n<p>\t\t\t\t\tRead more<\/p>\n<p>\t\t\t<a class=\"read-more__link\" href=\"https:\/\/www.cityam.com\/ftse-100-live-stocks-set-for-flat-open-after-falling-on-ai-jitters\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">FTSE 100 Live: Beazley seals $15bn Zurich deal, Santander in $12bn takeover<\/a><\/p>\n<p>\tUS markets slide on Anthropic blow<\/p>\n<p>Looking to he other side of the pond, tech stocks fell broadly on Wall Street overnight, with the Nasdaq sliding 1.4 per cent, the S&amp;P 500 down 0.8 per cent and the Dow Jones easing 0.3 per cent as most of the so-called Magnificent Seven tech giants moved lower.<\/p>\n<p>Asian markets were mixed on Wednesday morning, with Japan\u2019s Nikkei pulling back from recent highs while Chinese and Hong Kong equities traded higher.<\/p>\n<p>The falls came after US AI giant\u00a0Anthropic\u00a0unveiled a new tool aimed at automating legal work for corporate in-house teams.<\/p>\n<p>The product, launched by the company behind the Claude chatbot, is designed to carry out tasks that have historically underpinned revenues at many data-heavy businesses.<\/p>\n<p>The \u00a3350bn company\u2019s co-founder Dario Amodei warned last month in a <a href=\"https:\/\/www.cityam.com\/how-seriously-should-we-take-anthropic-founder-civilisational-threat-essay\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">20,000 word essay<\/a> that the development of AI will \u201ctest who we are as a species\u201d.<\/p>\n<p>He predicted that \u201cit cannot possibly be more than a few years before <a href=\"https:\/\/www.cityam.com\/anthropic-chief-ai-will-test-who-we-are-as-a-species\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">AI is better than humans<\/a> at essentially everything\u201d.<\/p>\n<p>\t\t\t\t\tRead more<\/p>\n<p>\t\t\t<a class=\"read-more__link\" href=\"https:\/\/www.cityam.com\/investors-are-nervous-will-google-and-openai-follow-anthropic-with-legal-tools\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">\u2018Investors are nervous\u2019 \u2013 will Google and OpenAI follow Anthropic with legal tools?<\/a><\/p>\n<p>\t\tSimilarly tagged content: <\/p>\n<p>\t\t\tSections\t\t<\/p>\n<p>\t\t\tCategories\t\t<\/p>\n<p>\t\t\tPeople &amp;
