Alphabet's dominant AI positions put it on the brink of overtaking Nvidia as the world's largest company by market capitalization.

Alphabet closed Friday with a market capitalization of $4.8 trillion, while Nvidia reached $5.2 trillion after a three-day rally into the end of the week.

Alphabet holds significant positions across nearly every aspect of the AI ecosystem, from its Gemini AI model (a type of large language model) to hardware, software, and services.

According to Luke O'Neill, chief investment officer at CooksonPeirce Wealth Management, the combination of Alphabet's AI offerings positions it as a prime contender to be the biggest winner of AI.
