Rosen Law files securities class action against Nvidia and CEO Jensen Huang over alleged spy-affair disclosures; Senator Coons seeks congressional probe (filed Nov 9)
What happened
Rosen Law Firm filed a proposed securities class action against Nvidia and CEO Jensen Huang in the U.S. District Court for the Northern District of California on Monday, Nov 9 — five minutes after the market close, per Reuters — on behalf of lead plaintiff Mark Kistenmacher and investors who bought Nvidia securities between Oct 9, 2025 and Nov 8, 2026. The suit alleges Nvidia and Huang made false and misleading statements and failed to disclose Huang's affair with Alice Huang, a former Megaspeed executive described as a suspected Chinese intelligence source, and the national-security questions it raised about Nvidia's dealings with Megaspeed. It cites spokesperson John Rizzo's statement that Huang's interactions with her were 'not unusual or unexpected' and Huang's Bloomberg comments that Nvidia's Megaspeed dealings were 'normal and not unusual' as deliberate falsehoods, and claims investors bought at artificially inflated prices and suffered losses when Huang acknowledged the relationship — an admission that wiped roughly $190 billion off Nvidia's market value in a single day. Separately, Delaware Senator Chris Coons called for a congressional investigation into the affair on national-security grounds. Wedbush analyst Dan Ives put the odds of Huang losing the CEO post at roughly 15% (85% he stays), while CNBC's Jim Cramer said investors may need to prepare for a future Nvidia without Huang. At least four law firms are now investigating, per TechCrunch, and a lead-plaintiff motion deadline of Jan 8, 2027 applies.

- Nvidia (NVDA) — direct defendant; down ~10% in two sessions since the probe broke, and down ~4% for 2026 after Monday's drop; the suit adds legal and leadership risk on top of the board probe
- Semiconductors / AI hardware — the governance overhang on the AI leader weighs on the chip trade, which had already been rattled by the post-midterm AI selloff
- Microsoft (MSFT) — passed Nvidia in market value for the first time since June 2025 as NVDA slid (MSFT ~$4.03T)
- Megaspeed-linked China chip-diversion exposure — any findings on Nvidia's dealings with Megaspeed could draw export-control scrutiny
