As investors debate whether custom AI chips will eventually chip away at Nvidia Corp.’s (NASDAQ:NVDA) dominance, Gabelli Funds portfolio manager John Belton says the latest releases from Meta Platforms Inc. (NASDAQ:META) and Space Exploration Technologies Corp‘s (NASDAQ:SPCX) xAI suggest the chipmaker’s competitive moat remains firmly intact.
In a recent note, Belton pointed to Meta’s Muse Spark 1.1 and xAI’s Grok 4.5 as evidence that frontier AI developers continue to rely on Nvidia’s infrastructure to train their most advanced models.
