Elon Musk and billionaire investor Bill Ackman on Monday publicly rallied behind NVIDIA CEO Jensen Huang, urging support for the chip giant's founder after reports emerged that he had been targeted by a Chinese espionage operation — and had acknowledged an extramarital affair with a former executive at a Singapore-based chip company. The controversy has triggered a broader debate over Huang's indispensability to US artificial intelligence leadership at a moment of acute geopolitical competition in semiconductors.

What Ackman and Musk Said

Bill Ackman, CEO of Pershing Square Capital Management, took to X to defend Huang, acknowledging the mistake while calling for public support. “An alert: @JensenHuang is human. And he is an incredible human. Even incredible humans make mistakes. He takes full responsibility as he should. We should all support him and his family. Onward,” Ackman wrote.

In a follow-up post, Ackman clarified that he was not advocating a “free pass”, adding that the gravity of the situation would depend on the nature of the controversy. “I like the guy. He has done a lot of good for the world and I hope the damage here is minimal,” he said, expressing hope that the matter was limited to a personal affair rather than constituting a national security risk.

Elon Musk responded briefly to a post by Sequoia Capital partner Shaun Maguire, writing: “I agree.” Maguire had described Huang as “one of the greatest entrepreneurs of this generation” while acknowledging he had made a serious mistake, noting it was “bad for America” but adding that he believed there was “probably no malicious intention” behind Huang’s actions. “Two mistakes don’t make a right, and I believe Jensen is irreplaceable for America’s AI leadership,” Maguire wrote.

The Espionage Allegations

US policymakers have alleged that the woman with whom Huang had the affair was recruited by China’s Ministry of State Security to gather intelligence on NVIDIA’s chief. The claim places a deeply personal matter at the intersection of US-China technology rivalry, where NVIDIA’s advanced AI chips — including the flagship H100 and Blackwell series — sit at the centre of export controls and sanctions disputes.

Notably, this comes amid an already tense backdrop of Washington restricting NVIDIA chip sales to China, making Huang’s personal conduct a potential national security flashpoint rather than a purely private matter.

NVIDIA Board Launches Independent Probe

NVIDIA’s board of directors announced it was initiating an independent investigation in response to the reports. In a statement, the board said it was acting “in light of recent reports that the company’s founder and CEO had been the target of a foreign intelligence effort.” No timeline for the investigation’s conclusion was provided.

Huang’s Apology to Staff and Family

In an email to NVIDIA employees, Huang issued a direct personal apology. “I was unfaithful to my wife. My actions hurt her and our children. There is no excuse for what I did. I am deeply sorry. Throughout my life, my family has given me love and support. They deserve my honesty and loyalty. Instead, I let them down and damaged the life we built together. I take full responsibility for what I did and the hurt I caused, and I accept the criticism that comes with it,” he wrote.

The public acknowledgement is unusual for a sitting CEO of a company valued at over $3 trillion, and it underscores the scale of pressure Huang is navigating simultaneously on personal, corporate, and geopolitical fronts.

Why This Matters for AI Leadership

NVIDIA currently commands an estimated 80% of the market for AI training chips globally, and Huang is widely credited as the architect of that dominance. Any prolonged distraction — reputational, legal, or investigative — raises questions about continuity of strategy at a company whose roadmap directly shapes the pace of global AI development. How the board’s independent investigation unfolds will be closely watched by investors, policymakers, and rivals alike.
