Nvidia reported a record $39.3 billion in revenue for the fourth quarter, a 78% increase year-on-year, driven primarily by a 93% growth in its data center segment. Despite these impressive results, the stock fell 4% due to supply constraints, rising competition, and macroeconomic concerns, including potential trade tensions with China. Looking ahead, Nvidia forecasts $43 billion in revenue for the next quarter, but the market is wary, awaiting evidence of long-term sustainability amid increasing scrutiny.
