ChatGPT's soaring popularity has added $5 billion to the wealth of Nvidia's founder as Wall Street bets on AI boom for the chipmaker

• OpenAI's popular language tool, ChatGPT, has spurred investors to bet on AI, which has led them to chip companies like Nvidia.

• Nvidia's cofounder, Jensen Huang, has seen his wealth grow by $5 billion so far this year, Bloomberg data shows.

• Nvidia has emerged as a dominant name in powering AI applications in cars and robots.

With the rise of OpenAI's language tool, ChatGPT, Wall Street traders are increasingly betting on chip-makers like Nvidia, which has climbed more than 34% this month.

As a result, CEO Jensen Huang, who cofounded the company in 1993, has seen his wealth balloon by more than a third to $18.9 billion.

According to Bloomberg's Billionaire Index, the $5.1 billion gain gives Huang the largest percentage gain to his net-worth among US billionaires so far this year.

The 59-year-old Taiwanese immigrant is coming off a less memorable year, as he was among other tech moguls who lost big money, including Meta's Mark Zuckerberg and Tesla's Elon Musk.

Microsoft this month reportedly invested $10 billion into ChatGPT's parent company, OpenAI, which has fueled interest in the artificial intelligence space overall. The bot has shown a capacity for a range of tasks such as writing stock stories, layoff emails, and even dating-app messages.
