The duo both own significant holdings of Nvidia stock, which has continued to rocket and pushed the chipmaker to a market cap of more than $4 trillion. Over the past year, Nvidia is up near-70%, and for 2025 alone is up 27%.

While Bloomberg’s index doesn’t reveal their exact net worth, the pair’s most recent SEC filings reveal some of their existing holdings.

Kress sold some 27,650 Nvidia shares for approximately $171 each, resulting in a cash influx of around $4.7 million, according to a Form-4 filing on July 15, 2025. But the filing also shows that Kress still directly retains millions of Nvidia shares—2,984,516 to be precise.

On top of that, the filing also shows hundreds of thousands of Nvidia shares are indirectly retained by Kress through trusts or immediate family members.

The story is similar for Puri, who directly owns 634,193 Nvidia shares per a Form-4 filing from late June. Those shares alone are worth more than $108m, but Puri also has indirect beneficial ownership of some 20 million Nvidia shares via various trusts, with a further 46,360 being allocated to a children’s trust of which he is a trustee.

The sales described in the Form-4 filings by Kress and Puri were made pursuant to a Rule 10b5-1 plan, which allows stock sales to be set up in advance by officers of publicly listed companies to avoid any accusations of insider trading.

The rule has a number of stipulations, chief among them that a formula (not a person) determines the number, price, and date of the trade. A third party who cannot be influenced by the client must also be employed to conduct the sales.

Huang himself, with a net worth of $153 billion, owns tens of millions of Nvidia stock both directly and indirectly. He’s also made it clear that compensating talent highly is necessary in the era of AI, when Big Tech giants are jostling for the best people.

While OpenAI, for example, has lost some of its team to Meta’s recently-created AI lab, Huang recently told a panel hosted by venture capitalists running the All-In podcast: “I’ve created more billionaires on my management team than any CEO in the world. They’re doing just fine.” He added: “Don’t feel sad for anybody at my layer. My layer is doing just fine.”

Huang is also well known for his tireless work ethic, saying he works from ‘the moment he wakes up,’ seven days a week—he can’t even watch a movie without his mind wandering to the Santa Clara-based company.

But that diligence also extends to making sure his key personnel are being compensated appropriately. While he errs away from one-to-one meetings with his direct reports, he said he does look at all employees’ pay.

He told the panel this month: “I review everybody’s compensation up to this day. I sort through all 42,000 employees, and 100% of the time I increase the company’s spend on [operating expenses]. And the reason for that is because you take care of people, everything else takes care of itself.”

Nvidia declined Fortune’s request for comment.

Tech billionaires are on the up

Huang has had such a run of wealth that he has surpassed Berkshire Hathaway CEO Warren Buffett, with the founder’s wealth up $38.5 billion this year alone.

The market has been buoyed by the promise of artificial intelligence—which is intrinsically linked to the success if Nvidia—sparked in part because of the launch of OpenAI’s ChatGPT.

He’s not alone in his good fortune. As well as the newly-minted billionaires found among Nvidia’s C-suite, alphabet’s Sundar Pichai also joined the ranks of 10-figure fortunes this week according to calculations by Bloomberg’s Index.

Pichai’s net worth reportedly hit $1.1 billion this month, courtesy of significant cash reserves and the CEO’s 0.02% stake in the company with a market cap of more than $2.3 trillion.

However, Pichai has sold a reported $650 million in Google-owner Alphabet stock over the past decade, while he has served as CEO—sales that today would have amounted to more than $1 billion in gains, winning him a net worth of some $2.5 billion per Bloomberg’s index.

Like his contemporaries at Nvidia, Pichai sold many of his shares through Rule 10b5-1 filings.
