Nvidia's Earnings Report to Determine Fate of $400 Billion Rally.

Nvidia's market value has increased by $400 billion this year, largely due to its involvement in artificial intelligence. However, the company's earnings report, due after markets close on Wednesday, will be closely watched to see if AI-related demand is translating into enough revenue to justify the stock gains. Investors will be looking for evidence that spending on AI computing is boosting sales, particularly in the data center business, which is the dominant provider of AI accelerator chips. Nvidia's revenue forecast for the current quarter is likely to top the average estimate on Wall Street by about $200 million to $300 million thanks to AI-related demand.
