Nvidia CEO's Resignation Over Alleged Affair With Suspected Chinese Spy Sends Shockwaves Through Phoenix's Chip Industry
Jensen Huang's abrupt departure from Nvidia amid a national security scandal is rattling Arizona's semiconductor ambitions, as the company's deep partnership with TSMC's north Phoenix fab hangs in the balance. Interim CEO Colette Kress, a University of Arizona alum, takes the helm as stock prices slide.
PHOENIX â The sudden resignation of Nvidia founder and CEO Jensen Huang, triggered by an extramarital affair with a woman suspected of being a Chinese spy, is raising urgent questions about the future of Arizona's flagship semiconductor project and the state's role in the U.S. artificial intelligence economy.
Huang stepped down after admitting to the relationship, which prompted national security concerns. The New York Times reported that five Nvidia employees also accused Huang of a romantic involvement with a subordinate, the company's vice president of healthcare. The scandal has shaken a company that sits at the center of the global AI boom and whose fortunes are tightly woven into the north Phoenix manufacturing hub operated by Taiwan Semiconductor Manufacturing Co.
TSMC's Arizona complex, a multi-fab site that has drawn billions of dollars in investment, manufactures the world's most advanced semiconductors â the chips Nvidia designs and depends on. The two companies have been partners for nearly three decades, a relationship Huang celebrated in Phoenix just over a year ago when the plant began mass production of AI chips.
"TSMC was our partner and made it possible for us to invent many new technologies, including the GPU," Huang said at the October 2025 event. "During the PC revolution, we were the fastest-growing company in the world. That would not have been possible without TSMC." He noted that in the time he stood on the stage, TSMC had earned $250 million.
The leadership upheaval is already rippling through financial markets, with stock prices for both Nvidia and TSMC falling. U.S. House Speaker Mike Johnson, a Republican, told CBS News the development was "big and shocking," adding that Nvidia is "a very important company not only in the U.S. economy, but for national security purposes."
Dan Ives, a partner and senior managing director at Yorkville Ives & Co., warned that the change at the top could alter the global balance of power in AI. "With him out as CEO, China could significantly narrow the gap vs. the U.S.," Ives said.
For Arizona, the stakes are substantial. The TSMC campus represents one of the largest private economic development projects in state history and a linchpin of efforts to build a domestic semiconductor supply chain. Any instability at Nvidia â TSMC's anchor customer for advanced AI chips â could affect production plans, hiring, and the broader cluster of suppliers and contractors that have grown up around the Phoenix site.
Nvidia has named Colette Kress as interim CEO. Kress, a University of Arizona graduate who joined the company in 2013, will continue serving as chief financial officer while the board searches for a permanent replacement. Her Arizona ties may offer a measure of reassurance to local officials and industry leaders watching the turmoil closely.
The resignation comes at a delicate moment for the U.S. chip industry, which has been pouring public and private money into domestic manufacturing to reduce reliance on overseas suppliers. Arizona has positioned itself as a central player in that effort, and the Nvidia-TSMC partnership has been a key selling point. How the new leadership navigates the scandal â and whether the partnership remains on solid footing â will be critical for the region's economic outlook.
