Nvidia revenue hits $81 billion

Despite the blowout earnings and a forecast of $91 billion for the next quarter, Nvidia's stock remained relatively flat as investors questioned the sustainability of the AI boom.

CEO Jensen Huang sought to reassure markets by highlighting a broad base of customers and the upcoming launch of next-generation 'Vera Rubin' chips.

The company also announced a massive $80 billion share buyback program and increased its dividend to reward shareholders.

Analysts warn that while Nvidia remains dominant, rising competition and geopolitical tensions over chip exports to China pose significant long-term risks.
