On Friday, Sen. Elizabeth Warren (D-Mass.) accused President Donald Trump of leveraging his office for personal financial gain after ethics disclosures revealed millions of dollars in Nvidia Corp (NVDA) stock trades ahead of major AI chip policy developments involving China.

Trump's Nvidia Trades Trigger Ethics And National Security Questions

Warren criticized Trump in a post on X after newly released financial disclosure forms showed the president reported more than 3,700 transactions worth hundreds of millions of dollars during the first quarter of 2026.

This included sizable trades in Nvidia, Microsoft Corp (MSFT), Amazon.com, Inc. (AMZN) and Meta Platforms, Inc. (META).

"Trump brought the NVIDIA CEO on his trip to China to lobby Xi Jinping to buy advanced AI chips," Warren wrote on X. "The President's corruption is a national security disaster."

According to the filings, Trump purchased between $1 million and $5 million in Nvidia stock on Feb. 10. Roughly one week later, Nvidia announced a significant chip agreement with Meta.

Separate disclosures also showed Trump acquired an additional $500,000 to $1 million in Nvidia shares shortly before the Commerce Department approved certain Nvidia chip sales to China.

Disclosure Forms Reveal Massive Trading Activity

The Office of Government Ethics filings list transaction ranges rather than exact figures, making the total scope difficult to determine precisely.

While some trades were labeled "unsolicited," the filings do not clarify whether Trump personally directed the transactions or whether they were managed through brokers or discretionary accounts.

The timing of the investments has intensified scrutiny over potential conflicts of interest, particularly as Trump continues to shape U.S. semiconductor and China trade policy.

OGE Declines To Clarify Trump Trading Details

When asked whether the trades reflected direct presidential activity, an OGE spokesperson declined to comment on specific disclosures, stating only that the agency remains committed to "transparency and citizen oversight."

Earlier this week, the U.S. government approved Nvidia's sale of its advanced H200 AI chips to 10 major Chinese technology companies, including Alibaba Group Holding Ltd. (BABA) and Tencent Holdings Ltd. (TCEHY).

However, Chinese government intervention has effectively halted all shipments.

Price Action: Nvidia shares closed Friday at $225.32, down 4.42% with the stock slipping an additional 0.40% to $224.41 in after-hours trading.
