The rapid valuation surge of Mercor to $10 billion signals a high-conviction shift toward the "AI data supply chain," where the most valuable investments are now in companies providing expert-level human data for model training. Investors should prioritize Vertical AI firms like Harvey (Harvey.ai), which has secured a dominant moat by integrating with over 60% of the top 100 U.S. law firms. While Mercor remains private, keep a close watch on competitors like Surge, Handshake AI, and Micro One as this "AI tutoring" sector matures and prepares for potential public exits. Monitor the aggressive expansion of OpenAI and Anthropic into high-margin professional services like law and medicine, as these models transition from general chat to specialized white-collar automation. Exercise caution regarding long-term labor plays in this space, as high-end gig work margins may compress once AI models successfully "solve" specific professional tasks.
