Stagwell has partnered with Palantir (PLTR) to build AI products for marketing. Penn notes that CEOs rank AI investment as their #1 priority, displacing sustainability. Wall Street is "jumpy" about AI ROI, but the actual implementation phase (application layer) is just starting. Companies like Stagwell that build the specific tools to *use* the data (via Palantir) will capture the productivity gains that justify the capex. LONG Stagwell and Palantir as application-layer winners. AI adoption slows due to regulatory hurdles or hallucination issues.
