Alphabet is on the cusp of overtaking Nvidia as the world's most valuable company, riding on a record stock rally fueled by its artificial intelligence efforts and booming cloud business. The potential ‌reshuffling would put the Google parent at the No.1 spot for the first time in more than a decade. ‌It last held that position briefly in February 2016 before Apple reclaimed the spot. The move reflects a dramatic shift in sentiment as Alphabet emerges as both a ​major AI services provider with its cloud platform and a key rival to Nvidia in chips through custom processors that have won customers such as Anthropic.
