Enterprise software CEOs are on the offensive after a series of post-earnings calls triggered by a market rout that wiped nearly $1 trillion from SaaS stocks in February 2026. The sell-off began when Anthropic launched AI plugins for its Claude Cowork agent — tools capable of automating workflows that companies like Salesforce, Oracle, and Workday have long charged for.

The SaaS-pocalypse Defense

Oracle's Mike Sicilia pushed back directly: "You've all heard that new companies coding quickly using AI will spell the death of SaaS. I don't agree with that at all." Oracle shares jumped 10% after the company predicted AI-driven revenue growth for coming quarters — its moat: deep enterprise data in finance, supply chain, and HR that's difficult to replicate.

Salesforce CEO Marc Benioff invoked the term investors have been throwing around — "SaaS-pocalypse" — and dismissed it, arguing Salesforce now functions as a platform that builds, deploys, and governs AI agents on top of proprietary customer data spanning 50 trillion records.

Nvidia CEO Jensen Huang called the idea that AI would replace software tools "illogical," adding further pushback to the narrative.

The Uncertain Middle

Not every company's defense is equally convincing. Workday, which runs on HR and payroll data formatted in industry-standard patterns, faces a harder challenge: analysts warn that standardized data offers less of a moat. Workday brought back founder Aneel Bhusri as CEO to navigate the transition, but shares are down more than a third this year and hit a five-year low last month.

The emerging consensus: proprietary, hard-to-replicate data is the best defense against the AI agent wave.
