AI chipmaker Nvidia reported a massive $57 billion in quarterly revenue on Wednesday, a whopping increase of 62 percent compared to the same period last year, exceeding Wall Street’s wildest expectations. “There’s been a lot of talk about an AI bubble,” Nvidia CEO Jensen Huang told investors during Wednesday’s earnings call. The stakes are enormous as the booming AI industry continues to concentrate market value at an astonishing rate. The industry’s market value of $4.4 trillion would make it the fourth-largest economy after the United States, China, and Germany by GDP. Whether Nvidia’s bullish tone will entirely wipe concerns of an AI bubble from the minds of investors remains uncertain.
