Anthropic Launches Plugins, Markets Reprice Trillions

Anthropic's late-January to February launches of Claude plugins and capabilities coincided with sharp market repricing, erasing roughly $1.5 trillion in market value over four weeks. Key rollouts included Claude Cowork (Jan. 30), Claude Opus 4.6 (Feb. 6), and Claude Code Security (Feb. 20), each coinciding with double-digit declines at incumbents like Thomson Reuters, LegalZoom, and RELX. The episodes highlight outsized investor sensitivity to modest AI product announcements.
