Nvidia's equity-investment book makes earnings vulnerable to an AI valuation downturn even if GPU sales hold up. Private and public stakes totaled about $99bn, or 31% of assets, in July; gains were $15.9bn in April and $7.8bn in July. Private holdings are marked on observable transactions or impairments, so losses could arrive in lumps. Nvidia generated about $127bn of free cash flow over four quarters, and the filing does not split private stakes by sector. x.com x.com
