Cathie Wood's ARK Buys 90,443 Nvidia Shares Amid Huang Probe

Cathie Wood's ARK Invest bought 90,443 Nvidia shares on Monday, November 9, 2026 — the first trading session after Nvidia's board opened an independent investigation into CEO Jensen Huang. At that day's closing price, the purchase was worth an estimated $16.2 million, according to ARK's daily trade file.

The buy was spread across five actively managed ETFs. The largest slice, 51,097 shares, went into the ARK Innovation ETF (NYSEARCA: ARKK), the fund most investors associate with Wood's name. The scale matters more than the headline number: $16.2 million is small relative to the size of ARK's funds, which points to a measured add rather than a major new commitment. In plain terms, ARK topped up a position it already believed in.

Why Nvidia Fell on November 9

Nvidia (NASDAQ: NVDA) closed down 4.27% at $178.67, its lowest close since April 7, 2026. The drop was stock-specific, not market-driven. The SPDR S&P 500 ETF Trust (NYSEARCA: SPY) gained 2.37% the same day, and ARKK itself rose 4.66%. When a stock falls 4% while its sector and its biggest holder's fund both rise, the cause sits with the company's own news.

That news broke on Sunday, November 8, in a staff memo from Huang. In it, he said he had fallen short and admitted he had been unfaithful to his wife. The board announced its probe the same day. The memo followed an October 29 report that U.S. intelligence officials had concluded Megaspeed executive Alice Huang — no relation to the CEO — was a suspected Chinese intelligence asset. China's Foreign Ministry called that account unsubstantiated.

The stakes here go beyond one CEO's personal conduct. Nvidia is the dominant supplier of AI chips, and the controversy touches two live wires at once: dependence on a single leader, and export controls. Any finding that links Huang's conduct to national security could make Washington tougher on chip sales to China. That's the mechanism investors are watching — a governance scandal could harden into a policy problem.

What Does the Probe Mean for ARK's Position?

ARK is betting the business survives the controversy. The numbers behind that bet are large. Nvidia's fiscal second-quarter revenue was $96.221 billion, up 105.85% year over year. For the third quarter, the company forecast $108.0 billion, plus or minus 2%. Sales are still more than doubling, and nothing disclosed so far affects demand for its chips.

This was also ARK's third straight session adding Nvidia. During the November 5 post-midterm AI-chip selloff, ARKK and a sister fund bought 252,592 shares, worth about $45.9 million at that day's $181.60 close. Going into November 9, ARKK already held 1,153,992 Nvidia shares — the fund's eighth-largest position at 3.67% of assets. In each fund, the new purchase came to roughly 0.15% to 0.16% of assets.

One caveat on the data: ARK's trade file is unofficial and leaves out creation and redemption activity — the process of issuing and retiring ETF shares. The firm's updated holdings files will show the final position.

What Did ARK Sell to Fund the Buy?

Wood's pattern is familiar to anyone who follows ARK: she buys weakness in names she favors and pays for it by trimming other holdings. November 9 fit that template exactly:

• ARKK sold 72,700 Tempus AI shares, 68,997 Block shares, and its last 519 Broadcom shares
• Other ARK funds sold 8,509 Palantir shares, 150,588 BYD shares, 3,712 Synopsys shares, and 64,295 shares of ARK's own spot Bitcoin ETF
• ARK also bought 405,720 SoFi shares

In this reshuffle, Wood moved AI money out of Broadcom and Palantir and into Nvidia at a lower price. That's an active rotation within the AI trade, not a retreat from it.

How Does Nvidia's Valuation Stack Up?

Nvidia trades at a trailing price-to-earnings ratio of about 36x — share price divided by the past year's earnings per share. That multiple looks modest against a company whose revenue is still more than doubling. The valuation question now hinges less on growth and more on whether the Huang probe stays personal or bleeds into export policy.

It's worth keeping ARK's exposure in perspective. Nvidia makes up only 3.67% of ARKK, so most of the fund's assets sit in Tesla, crypto and biotech names that drive its returns. The Nvidia add is a conviction signal, but it isn't the fund's engine.

Other prominent investors have weighed in publicly. Bill Ackman wrote on X: "Even incredible humans make mistakes." He said he hoped the matter would stay personal rather than become a national-security problem. That framing — personal lapse versus systemic risk — is the exact fault line the board's investigation will have to resolve.

What Comes Next?

Nvidia's next earnings report will show whether the business is holding up. It is expected on Tuesday, November 17, after the close, although the company has not confirmed the date. The report lands a week and a half into the board's probe, giving investors the first hard read on whether chip demand has absorbed any of the noise.

There's also a clean technical marker for judging ARK's timing. If Nvidia closes below its April low of $178.10 after that report, ARK bought too early. The stock's November 9 close of $178.67 sits less than a dollar above that line — meaning the market has already priced the controversy almost exactly down to its 2026 floor. The takeaway: ARK's add was small, deliberate, and premised on the business outrunning its CEO's headlines; November 17 will test that premise.
