Nvidia and Chief Executive Jensen Huang face a proposed securities class action alleging they misled investors about business risks tied to Huang’s reported relationship with a former executive of Singapore-based Megaspeed. The federal complaint, filed Nov. 9 in Northern California, seeks damages for a proposed class of Nvidia securities buyers. On Tuesday, Nvidia’s independent directors announced the appointment of outside counsel to lead their separate inquiry.

Nvidia shares closed Tuesday at $168.89, down $9.78, or 5.47%, from Monday’s close, according to market data. The lawsuit was filed after Monday’s regular trading session, Reuters reported. Earlier TAQ coverage examined the potential effects of Monday morning’s sell-off on margin accounts and had found no publicly available complaint at that time. The new filing sets out an investor’s allegations; it does not establish misconduct or entitle investors to compensation.

What the shareholder alleges

Mark Kistenmacher, the named plaintiff, alleges that Nvidia and Huang made misleading statements or omitted information investors needed to assess the company’s dealings with Megaspeed and its exposure to export-control and reputational risks. The Associated Press reported that Nvidia previously said its compliance team had reviewed Megaspeed and found no illegal activity by the company. The plaintiff contends that Nvidia’s statements were misleading in light of the reported relationship. The allegations have not been decided by the court.

The complaint seeks unspecified damages and a jury trial. It asserts securities fraud claims under federal law, including a claim that Huang is liable as a person who controlled the company. The case concerns what Nvidia and Huang told investors and what the plaintiff says they left out. It is a civil lawsuit, and neither the filing nor Nvidia’s decision to investigate establishes that any information passed to a foreign government.

The case was filed in the U.S. District Court for the Northern District of California under docket number 5:26-cv-13448. The filing cites an October 2025 news report that described contacts between Huang and the Megaspeed executive and quoted Nvidia’s account of its compliance checks. The plaintiff is challenging the adequacy of disclosures around those reports, rather than asking the court to enforce restrictions on chip exports.

The board hires outside counsel

On Nov. 8, Nvidia’s board said it was initiating an independent investigation after reports that Huang had been the target of a foreign intelligence effort. On Nov. 10, the independent directors said they had retained Joon H. Kim and his firm, Wachtell, Lipton, Rosen & Katz. Kim is a former acting U.S. attorney for the Southern District of New York. The directors announced the appointment without releasing any investigative findings.

Nvidia did not immediately respond to the AP’s request for comment on the lawsuit. The news agency separately reported that Huang told employees he supported the board investigation and would cooperate. Those are different responses to different proceedings: the board is examining the reported conduct, while the plaintiff is asking a judge to determine whether investors were misled and suffered losses as a result.

Who the proposed class would cover

The proposed class covers investors who bought or otherwise acquired publicly traded Nvidia securities from Oct. 9, 2025, through Nov. 8, 2026, subject to exclusions. The dates come from the plaintiff’s filing; they are not a court-approved definition. Under Rule 23 of the federal civil rules, the court must decide whether to certify a class and, if it does, define who belongs to it and which claims it covers.

Federal securities law also sets out a separate process for appointing a lead plaintiff. The lawyers who filed the case issued a public notice on Tuesday identifying Jan. 8, 2027, as the deadline to seek that role. That is a deadline to ask to represent the proposed class, not a deadline to claim a payout. No class certification or damages award was identified in the public record reviewed for this article.

What the latest price move shows

The stock had already fallen 4.27% on Monday, closing at $178.67, according to the price history. Tuesday’s close left the shares about 9.5% below Friday’s close. The Journal reported that Tuesday’s selling came amid broader concerns about inflation and artificial intelligence stocks. A closing price measures the market move; it cannot isolate how much investors attributed to the lawsuit, the board review or the broader sell-off.

That distinction matters in court. The federal statute puts the burden on the plaintiff to prove that the alleged violation caused the loss for which damages are sought. A fall in the share price is observable, but the amount of any legally recoverable loss remains unresolved. Separately, Nvidia is scheduled to discuss its quarterly results on Nov. 17. That is a scheduled investor update; the board did not give a date for any findings in its inquiry. The next developments to watch are the defendants’ response to the complaint and any findings the independent directors choose to release.
