What changed?
The pipeline is no longer dominated by model laboratories alone. It includes data-center developers, energy and infrastructure providers, autonomous systems, and regional model companies. That broadening is strategically important because public markets will begin assigning separate values to model capability, distribution, compute access, physical deployment, and contracted infrastructure.
The core analytical rule is simple: do not combine an IPO target, a private valuation, a capacity contract, and recognized revenue into one growth narrative. Each carries a different probability, timing profile, financing requirement, and path to cash flow.
