Nvidia Has Shed $450 Billion Since Huang Admitted the Affair

By Tom Whitfield

Nvidia has lost more than $450 billion in market value since Nov. 8, when CEO Jensen Huang admitted an affair with an executive U.S. officials link to China's Ministry of State Security. The number keeps growing, and most of the people holding the loss never chose the stock.

Shares fell nearly 8% in after-hours trading Wednesday after the Wall Street Journal reported the board is preparing to oust Huang and could meet imminently to decide his future. The stock had closed the regular session up about 3%, at $173.73, then slid to roughly $160 post-market, per Yahoo Finance. The same day, the New York Times reported a second extramarital relationship, with Kimberly Powell, Nvidia's vice president of health care.

The admitted affair involves Alice Huang of Singapore-based Megaspeed International, whom U.S. officials believe is a Chinese intelligence agent, per the AP. The two are not related. What Nvidia's board knew, and when, remains undisclosed. The board's investigation may also examine past statements the company and its executives made about Megaspeed — a thread nobody has yet pulled publicly.

Takeaway: an 8% after-hours drop on top of $450 billion already erased, with the leadership question unresolved.

How much of a typical 401(k) is Nvidia?

Nvidia, No. 16 on the 2026 Fortune 500, was worth about $4.1 trillion at Wednesday's close — second only to Apple, per Companies Market Cap. A company that size sits inside the index funds and target-date funds that anchor millions of 401(k)s, whether savers chose it or not. Founded in April 1993 and public since January 1999, Nvidia became the first company to reach a $5.5 trillion market cap in May 2026.

Leonard Gilroy, senior managing director of the Reason Foundation's Pension Integrity Project, put numbers on the exposure:

• "The average American's exposure to NVIDIA stock volatility depends on how they invest, but a reasonable estimate is 3% to 5%."
• Nvidia is about 6% of the S&P 500's total market cap and about 10% of the NASDAQ100's.
• A total wipeout of Nvidia would cost a pure index-fund investor roughly 5% to 10% — the worst case, and most accounts spread far wider.
• About 70% of 401(k) assets sit in public equities.

Public pensions are less exposed. Gilroy said Nvidia accounts for about 2.5% of the average public pension fund's assets, since public equities make up only 46% of assets under management. "So it's worth watching, but overall the current direct exposure to NVIDIA is not a major concern for public pension systems," he said. Concentration risk persists, given Nvidia's weight relative to other holdings.

Takeaway: direct exposure is 3% to 5% for a typical saver — real, but bounded.

What about spillover to other AI stocks?

The larger danger may be the domino effect. "What happens to one major player in a dynamic market can spill over to other firms, such as AI companies and other large consumers of NVIDIA chips, so indirect investment risks beyond NVIDIA's own performance can be significant," Gilroy said.

Leadership compounds it. Huang has run Nvidia since co-founding it in 1993; Bloomberg reports the company is working with an outside firm to explore replacements. No successor has been named, and no timetable disclosed.

Takeaway: the second-order exposure — Nvidia's chip customers — is the risk nobody has quantified.

Why experts say savers should sit tight?

Jill Fisch, a professor at the University of Pennsylvania Carey Law School, advises restraint. "Ordinary retirement accounts are invested for 20, 30, or 40 years or more," she said. "So I would say over the long term, this is going to be a tiny blip."

She drew a line between the affair and what could follow. "With respect to possible outcomes, we don't know much of anything at this point," Fisch said, adding that the affair itself should not materially affect the company's value. "Obviously, if there are security issues or if the existence of the affair has raised questions about long-term leadership of the company, those are more problematic." She pointed to Apple, whose stock swung on Steve Jobs's cancer diagnosis in the 2000s yet proved a strong long-term holding.

Gilroy urged institutions, too, not to overreact: maintain diversified, risk-managed portfolios that "avoid single points of failure." Fisch's advice is simpler. "They're going to go up and they're going to go down; don't check the value of your portfolio that often," she said. "Go play with your grandkids."

Caveat duly noted: both prescriptions assume the board's probe ends at an affair. If it ends at a security breach, the arithmetic changes.
