4 tech moguls who attended or donated to Trump's inauguration got $288 billion richer, cumulatively, in his first year back

• Elon Musk, Jeff Bezos, Mark Zuckerberg, and Jensen Huang got wealthier during Trump's first year back.
• The tech billionaires supported Trump's inauguration either through attendance, a donation, or both.
• Musk, who was the closest to the Trump White House, saw his wealth increase by over 50%.

It's been one year since President Donald Trump was sworn back into office — and four of the wealthiest tech billionaires who attended or donated to his inauguration have gotten richer.

Elon Musk, Mark Zuckerberg, Jeff Bezos, and Jensen Huang — all of whom are featured on Bloomberg's list of 500 wealthiest people in the world — were among the tech royalty who signaled support for the administration, either through attendance or a donation. Others included Tim Cook, Sam Altman, Sundar Pichai, Satya Nadella, and Shou Zi Chew.

The tech billionaire with the largest increase in his net worth during Trump's first year is also the one who was closest to the Trump administration: Elon Musk. According to the Bloomberg Billionaires Index, the Tesla CEO's wealth increased by 52% over the past year.

While Musk, Zuckerberg, Bezos, and Huang are all wealthier today than they were on Inauguration Day in 2025, there have been some ups and downs. Collectively, the group lost $194 billion in wealth during Trump's first 100 days as markets reacted to the administration's tariffs. They've since made up for those losses and then some. As of January 19, the group was cumulatively $288 billion wealthier than a year prior.

Here's where all four stood as of Monday, January 19, 2026.

Elon Musk

Net worth January 19, 2025: $449 billion

Net worth January 19, 2026: $681 billion

Percent change: +52%

After spending at least $277 million backing Trump and Republicans during the 2024 election, Musk attended the inauguration and worked closely with the White House as the public face of the White House DOGE Office. Following his departure in May, Musk and Trump had a very public falling out, though they later reconciled.

Musk's work with DOGE resulted in backlash against Tesla, with the company's share price declining in the first few months of Trump's presidency. It has since recovered, and in the year since Trump was elected Musk has solidified his standing as the world's richest man. In November, Tesla shareholders approved a $1 trillion-dollar pay package for the Tesla CEO, if he hits a series of goals, and there are plans for a SpaceX IPO in 2026.

Jeff Bezos

Net worth January 19, 2025: $245 billion

Net worth January 19, 2026: $261 billion

Percent change: +7%

Bezos's wealth, most of which is tied to Amazon stock, has increased since Trump took office a second time. Bezos, the Amazon founder and chairman, attended the inauguration alongside his now-wife Lauren Sánchez. Amazon also donated $1 million to the president's inaugural committee.

Analysts have said that Amazon was especially at risk of being negatively impacted by Trump's trade war, and CEO Andy Jassy said this week prices on the platform are increasing as a result of tariffs. Amazon's share price is roughly the same as it was a year ago.

Mark Zuckerberg

Net worth January 19, 2025: $217 billion

Net worth January 19, 2026: $220 billion

Percent change: +1%

Zuckerberg and Trump once had a contentious relationship that went back several years prior to the 2024 election, with the latter at one time threatening to have the Meta CEO jailed over Facebook banning Trump's account in the wake of the January 6 Capitol riot.

Zuckerberg publicly warmed to Trump during the 2024 cycle, offering him praise and attending the inauguration. Zuckerberg was seated next to Trump at a White House dinner attended by tech leaders last year. Meta also donated $1 million to the inaugural committee.

Jensen Huang

Net worth January 19, 2025: $117 billion

Net worth January 19, 2026: $154 billion

Percent change: +32%

Huang did not attend the inauguration, but Nvidia donated $1 million to the inaugural committee. The Nvidia CEO also met with Trump shortly after he took office and the company has worked with the White House on AI policy.
