Trump Bought Nvidia Stock While Shaping China Chip Policy

Donald Trump bought between $1 million and $5 million of Nvidia stock in the days before he scrapped export controls designed to keep America's most advanced AI chips out of China. That's what his own financial disclosures show, according to an analysis by the anti-corruption group DeKleptocracy. The rule he rescinded in May 2025 was a Biden-era measure. Its purpose was twofold: strengthen the US chip industry and block China from developing superior AI, which officials widely regarded as a national security threat.

The timing is the story. Trump's purchases landed in the days before the rescission. Nvidia's shares rose in value just after he announced the decision — and after he had bought the stock. Nvidia wasn't his only tech holding, either. The same disclosures show he bought shares in Microsoft, Meta and Apple.

Why did the 'diffusion rule' matter to Nvidia?

The rule, known as the diffusion rule, would have limited Nvidia's ability to sell into one of its largest markets. China accounted for roughly a quarter of Nvidia's sales between 2010 and 2022. Killing the rule opened that market back up. The stock responded accordingly.

Then the policy loosened further. In December 2025, Trump said he would allow Nvidia to sell H200 chips to China. The Department of Commerce greenlit the decision in January 2026. This was controversial, and for a concrete reason: experts said the H200 was one of Nvidia's most advanced chips and roughly six times better than anything available in China at the time. The Council on Foreign Relations warned that selling H200s would "supercharge" China's future AI factories and strengthen a US rival.

What did Trump buy after the H200 decision?

His disclosures show at least three more Nvidia purchases in the days after that December announcement. Each one fell between $250,001 and $500,000. These are among his larger Nvidia buys. They sit within what appears to be dozens of transactions involving the chipmaker's shares since he took office. One president, one chipmaker, a steady drip of trades.

DeKleptocracy didn't mince words in its analysis: "While the country debates how a possible Chinese spy may have manipulated White House policy for one AI company, it must grapple with how Trump's corruption may have motivated him to deliver the entire AI industry's technology to China."

How does the Jensen Huang affair connect?

The stock trades don't sit in a vacuum. The US — and the global economy — have been grappling with revelations that Jensen Huang, Nvidia's former chief executive, had an affair with an alleged Chinese spy named Alice Huang. Reports have suggested the relationship allowed Alice Huang's company, Megaspeed, to obtain billions of dollars worth of Nvidia's chips while other companies struggled to get supply.

US intelligence officials briefed Trump twice on their conclusion that Alice Huang was a Chinese asset. He did not act on that assessment. The intelligence reached him. Nothing changed.

The relationship between Trump and Jensen Huang adds another layer. Huang has been described as a close Trump ally and has met the president a number of times. In October 2025, Nvidia made a $25 million contribution to Trump's ballroom. Huang said he was "delighted to be a part of it."

What are the stakes?

The pattern here matters beyond one portfolio. Export controls on AI chips are among the most consequential policy tools the US has in its competition with China. The rules decide which companies can sell which silicon, into which markets, and at what strategic cost. When the person setting those rules also trades the stock of the company most affected — in both directions, on repeated occasions, timed to his own announcements — the policy process loses its claim to neutrality.

Nvidia's China exposure makes the conflict direct. A quarter of the company's sales over more than a decade came from China. The diffusion rule threatened that revenue. Trump bought the stock, then removed the threat. Later, he approved the sale of the H200 — a chip experts called six times better than China's domestic options — and bought more stock in the days that followed.

DeKleptocracy's framing pushes the question from individual trades to systemic risk: if the White House's China AI policy is shaped by personal financial interest, then the safeguards designed to keep advanced US technology out of rival hands aren't safeguards at all. The disclosure filings that reveal these purchases are public. Whether Congress or regulators treat them as a trigger for investigation, rather than a footnote, is the question that now sits with Washington — and with an AI industry whose most valuable export market was reopened by the man trading its shares.
