Anthropic Launches Claude Opus 4.6 Amid AI-Driven Sell-Off in Software Stocks

An AI startup, Anthropic (ANTH.PVT), released Claude Opus 4.6, an upgraded model with improved reliability for long tasks and gains in coding and finance, Feb 5, 2026. The update claims to process 1 million tokens per prompt, matching capabilities earlier claimed by Google and a less powerful Claude model. The release follows a broader selloff in traditional software stocks as Anthropic and other generative AI firms compete to integrate into legacy tools and workflows. Shares of Salesforce, Workday, and Thomson Reuters fell about 3% on Feb 5, extending recent declines. Enterprise head of product Scott White said the company aims to connect AI with older software to "lower the floor" and deliver more value, emphasizing partnerships to enhance existing tools.
