The market is buzzing about a "SaaSpocalypse" after Anthropic released their Claude Cowork platform. The S&P 500 Software index is down nearly 19% since the launch, erasing $300 billion in value. The main worry is that AI agents can now execute workflows autonomously, which threatens the traditional per-seat pricing model. If an AI does the work, companies need fewer user licenses. Salesforce, Workday, and Atlassian are all down sharply. Capital is rotating into AI infrastructure like Nvidia and Microsoft, and even crypto is taking a hit as funds shift focus to this new tech.
