Anthropic's Claude Cowork Release Crashes SaaS and Agency Stocks
Anthropic's expansion of its AI tool Claude Cowork with specialized functions for marketing, law, and finance has triggered a broad sell-off in technology stocks. Investors fear that AI agents can automate tasks traditionally requiring expensive specialized software and human resources, threatening the subscription-based SaaS model and the value of professional information services. Major losses include Thomson Reuters (-18%), RELX (-14.4%), Wolters Kluwer (-13%), and advertising holding companies Publicis (-9%), Omnicom (-11%), and WPP (-11.8%). Chip makers also fell, with AMD seeing its worst day since 2017 (-17.3%) despite solid earnings. The market reaction reflects growing uncertainty about the impact of generative AI on established business models. Anthropic is reportedly preparing a new funding round at a valuation above $350 billion, highlighting the divergent fortunes of AI innovators versus traditional software vendors.

Nokia CEO: Data centers would be built 2x faster without shortages
Nokia CEO Justin Hotard told CNBC that AI data center demand remains robust, and customers would build twice as fast if not for supply constraints like memory chip and energy shortages. This comes despite debates about slowing AI development. Nokia, a major telecom equipment maker, has pivoted to AI infrastructure, selling technology to connect chip racks and interconnect data centers. The company's stock is up about 130% in the past year. Hotard emphasized that even without new frontier models, deploying existing technology offers significant progress. The article also notes that AI buildout investments could total $10.3 trillion from 2025 to 2032, and that recent safety concerns from Anthropic researcher warnings caused a selloff in AI stocks.
Menlo’s Investment in Factory: The System That Builds Software
Coding is AI’s first killer use case, with the world generating more code this year than in all previous years combined. Menlo Ventures has invested in Factory, a company building the system that builds software, as part of the AI coding startup’s latest funding round, announced last month at a $5 billion valuation. The investment follows a public dispute between Factory's CEO, Matan Grinberg, and investor Chris Degnan, who left to join competitor Cognition. Vinod Khosla, an investor in both companies, criticized Factory as a 'struggling second tier competitor.' Menlo's investment is seen as a strong endorsement, with partner Matt Murphy praising the company. The exact amount was not disclosed but described as significant.
AI helps self-represented litigants in courts
This article from Exponential View discusses the growing role of AI in assisting self-represented litigants in court cases.
