30-second brief

NVIDIA fell 4.27% against the trend on a rebound day for U.S. stocks, with about US$190 billion in market value wiped out. CEO Jensen Huang's net worth shrank by more than US$6 billion in a single day, as shareholder class-action lawsuits and investigation concerns continued to escalate. Forbes and Bloomberg rank him 10th and 12th respectively, while marital property division has also drawn attention.

Monday was the first U.S. trading day after Jensen Huang admitted marital infidelity, following reports that NVIDIA's board had launched an investigation into him over related concerns. Despite a strong overall rebound in U.S. stocks that day, NVIDIA closed down 4.27% at $178.67 per share, with about US$190 billion in market capitalization wiped out in a single day, or about NT$6.25 trillion, with the market pointing to a class-action lawsuit filed by shareholders as the main cause.

Jensen Huang's personal net worth also shrank in tandem. According to Forbes, his net worth evaporated by US$6.8 billion in a single day, or about NT$2235.98 hundred million, and he now stands at US$155.4 billion, or about NT$5.11 trillion, ranking as the world's 10th richest person. According to Bloomberg, it evaporated by US$6.47 billion in a single day, or about NT$2127.47 hundred million, and he now stands at US$148 billion, or about NT$4.87 trillion, ranking as the world's 12th richest person, falling out of the top 10.

Shareholders file class action alleging concealment of national security risks

According to filings and the lawsuit, NVIDIA shareholders have filed a class-action lawsuit in the U.S. District Court for the Northern District of California against CEO Jensen Huang and NVIDIA. The lawsuit alleges the company concealed Jensen Huang's relationship with Alice Huang, who is suspected of ties to Chinese intelligence agencies. It also alleges the company concealed national security risks related to Megaspeed, ultimately triggering a sharp drop in NVIDIA's share price.

41-year marriage in spotlight with community property in focus

In an email sent to employees on Sunday, Jensen Huang admitted marital infidelity and apologized to his family and colleagues. He and his wife Lori Huang have been married since the mid-1980s for 41 years, having first met while studying at Oregon State University, before he founded NVIDIA. Jensen Huang has said Lori has been involved in every step of NVIDIA's development. According to NVIDIA's 2026 proxy statement, most shares attributable to Jensen Huang are actually held through trusts, with both spouses serving as co-trustees of the relevant trusts, potentially deemed to share beneficial interests. It is currently unclear whether the two signed any prenuptial or postnuptial agreements. California applies community property, under which property acquired during marriage is generally divided equally, with outside estimates putting a hypothetical allocation at at least US$75 billion, or about NT$2.47 trillion. However, there is currently no indication that Lori has filed for divorce or is considering separation, and the actual split would depend on agreements and property characterization. According to Bloomberg analysis, his net worth comes mainly from NVIDIA equity, holding about 3.4% of NVIDIA in his own name and through family trusts per September 2026 filings.
