Nvidia has reported a record revenue of $57 billion for the third quarter of 2025, exceeding Wall Street estimates and calming investor fears about the AI bubble. The company anticipates revenue will rise to $65 billion in the fourth quarter. This announcement led to a more than 5% increase in Nvidia's stock price. Meanwhile, Berkshire Hathaway disclosed a $4.3 billion stake in Alphabet, suggesting a strategic investment in Google's potential within the AI landscape. Warren Buffett's firm has historically favored companies with strong competitive advantages, and this move indicates confidence in Google's ability to navigate the evolving digital economy. Despite concerns about the sustainability of AI growth, both Nvidia and Alphabet are positioned to weather potential downturns better than newer tech giants.
