1. The AI boom goes bust. Nvidia sales and/or margins crater. The stock craters with it.
2. The AI boom is the real deal. Companies aren’t stupid and won’t keep paying Nvidia these prices forever. Pretty soon hardware and software architectures are standardized enough that anyone who can get onboard with TSMC, Samsung, or Intel can churn out hardware optimized for the right few functions and sell for a faction of the price. Nvidia can still be an innovator but they won’t be able to sell “bread and butter” products at these prices. Sales and/or margins crater, as does the stock.
