## Recent evidence

- [confirms] Nvidia Falls 5% and Cedes Most-Valuable Crown to Apple as AI Financing Fears Hit Global Chip Stocks (2026-07-28): Reports that Nvidia would guarantee roughly $250B of OpenAI data-center debt sent Nvidia down 5% (ceding the most-valuable crown to Apple, which Polymarket now prices at 78% vs Nvidia's 21% for month-end) and knocked South Korea's Kospi down over 10% with Samsung and SK Hynix each off ~12%. This is the thesis's exact mechanism—vendor guaranteeing a customer's debt—now producing a correlated, cross-border repricing, confirming each disclosure makes the trade more fragile.
