Nvidia's market cap dropped around $500 billion since it became the world's most valuable company. Skittish investors were awaiting comments at its annual meeting that might reverse the trend. CEO Jensen Huang discussed Nvidia's success but didn't offer new information on how it will compete with rivals or details on its next-gen AI chip, Blackwell. Huang failed to provide a timeline for when Blackwell will be available, though he said it will be Nvidia's most successful product. The stock stayed down more than 2% after the meeting.
