This report profiles late-stage (Series C+) private AI companies across seven categories, highlighting a combined $1.2T+ valuation and $225B in 2025 AI VC deployment, with foundation models and infrastructure capturing the bulk of value. It ranks IPO readiness based on revenue scale, profitability path, governance, and competitive moat—identifying Databricks, Cohere, Anysphere (Cursor), and Abridge as top near-term IPO candidates, while flagging foundation model leaders like OpenAI and Anthropic as structurally constrained but highly valuable. The analysis also maps key risks (valuation bubbles, compute costs, regulation, hyperscaler competition) and practical public-market exposure routes via big-tech equities, secondary markets, and AI-tilted funds.
