# Legacy SaaS Under Siege: Investors Bet AI Will Erode Traditional Moats

Traditional SaaS stocks tumble as AI-native tools and coding agents threaten seat-based business models.

**The News:** Shares for major traditional SaaS players, including Atlassian, Salesforce, and Workday, have tumbled to 52-week lows. The market shift reflects growing investor sentiment that generative AI—particularly AI coding agents and autonomous workflows—will erode the established business models of traditional seat-based software.

**Analyst Critique:** This is the much-anticipated "SaaS correction" playing out in real time. For years, traditional SaaS relied on "seat-based" pricing and vendor lock-in. However, AI-native platforms are shifting to consumption-based or outcome-based models. Legacy vendors are rushing to "bolt-on" AI to stop the bleed, but the next generation of SaaS companies is building AI into their core product from day one. Expect more consolidation and potential M&A activity as traditional titans try to buy their way into the AI era.
