STORY: Nvidia posted better-than-expected results for the January quarter on Wednesday (February 25) and forecast current-quarter revenue above market estimates.The chipmaker reported that January-quarter sales rose 94% to $68.13 billion, beating estimates of $66.21 billion. It also expects fiscal first-quarter sales of $78 billion, above forecasts of analysts.But shares in Nvidia traded flat after hours.That is as investors, used to solid revenue beats from the company for 14 straight quarters, were likely disappointed by the uneventful results that were released 10 minutes after the expected time.On the post-earnings conference call, Nvidia executives were asked if the company was looking to give back to shareholders some of the $100 billion cash it was likely to generate this year.In response, Nvidia Chief Financial Officer Colette Kress said the company wanted to keep investing in the AI ecosystem.CEO Jensen Huang said the output generated by AI models would be the foundation of future computing and Nvidia would keep building more infrastructure to support that.The company also said it had secured enough chip inventory and capacity to meet demand beyond the next several quarters. But it added that the shortage will affect its gaming business.:: AMD:: GoogleStill, there are signs of risk to Nvidia’s long-held dominance in making AI chips, with rivals AMD and Google clinching big deals with top customers.
