Por que o Jensen Huang da Nvidia está no centro de um escândalo de espionagem entre EUA e China? | Notícias de Tecnologia | Al Jazeera Pular links Pular para o conteúdo Reproduzir ao vivo Inscreva-se Mostrar menu de navegação Menu de navegação.

Allegations linking CEO to Chinese intelligence shake markets with chipmaker’s shares falling more than 4 percent.

Huang – who cofounded Nvidia, the world’s second-most valuable company after Apple, more than three decades ago – admitted on Sunday to being unfaithful to his wife, but the company said it has no reason to believe United States national security or confidential information has been compromised.

No entanto, o conselho da Nvidia anunciou uma investigação independente sobre se o cidadão de dupla nacionalidade Taiwan-US, de 63 anos, havia sido alvo de uma operação de inteligência estrangeira, após relatos da mídia que o ligavam a Alice Huang, ex-executiva de uma empresa de centros de dados sediada em Cingapura.

The controversy erupted as Washington seeks to prevent China from obtaining advanced American semiconductors, including Nvidia’s most powerful artificial intelligence chips, as the US and China fiercely compete for AI supremacy.

So what do we know about the affair, and how will this impact US-China relations and the race for AI dominance.

The allegations first emerged in a New York Times investigation late last month, which reported that US intelligence officials believed Alice Huang had been recruited by Beijing to gather information about Nvidia’s chief executive and potentially influence the company’s chip sales to China.

However, the precise nature of the information she allegedly obtained, whether any sensitive material was passed to Beijing and how much Jensen Huang knew about the alleged operation remain unclear.

Jensen Huang e Alice Huang não são parentes, apesar de compartilharem o sobrenome.

Os dois foram supostamente vistos juntos em eventos do setor, incluindo um jantar organizado por Jensen Huang em Taipei durante a exposição de tecnologia Computex em 2025.

On Sunday, the Nvidia chief acknowledged his infidelity in a staff memo.

However, in late October, Jensen Huang had told Bloomberg News that his interactions with Alice Huang were related to her company, Megaspeed, describing them as “completely normal and not unusual”.

Também conhecida como Huang Le, Alice Huang é cidadã chinesa e ex-executiva sênior da Megaspeed International, que fornece infraestrutura de computação usada para operar e treinar sistemas de IA.

Um perfil de Alice Huang encontrado em um banco de dados de investimentos chinês listou empregos anteriores na HSBC e nas emissoras de televisão chinesas CCTV e Hunan TV, segundo a agência de notícias AFP, que disse que não pôde verificar esses detalhes de forma independente.

Alice Huang has not publicly responded to the espionage allegations, and her whereabouts are currently unknown.

Nvidia has launched an independent investigation overseen by a committee of directors and external legal counsel to determine whether its president and CEO was targeted by foreign intelligence.

The company said it had no reason to believe national security or its proprietary information had been compromised while expressing confidence in Jensen Huang’s leadership.

No entanto, as alegações têm abalado os investidores.

Jensen Huang’s daughter, Madison, who also works at Nvidia, cancelled a planned visit to South Korea for an Nvidia AI event amid the controversy.

What action has the US government taken.

Autoridades dos US têm investigado a Megaspeed desde 2024 por suspeitas de que a empresa ajudou a China a obter chips avançados da Nvidia em violação das restrições de exportação dos US.

However, no criminal charges against Jensen Huang or Alice Huang have been reported. The controversy has prompted bipartisan pressure in Washington.

Republican lawmakers on Wednesday called on Jensen Huang to testify before Congress on November 18, arguing that the allegations raise serious questions about China’s potential access to sensitive US technology.

A senadora democrata Elizabeth Warren também exigiu respostas da Nvidia e pediu legislação mais forte para impedir que tecnologia avançada dos EUA chegue à China.

Presidente Donald Trump, enquanto isso, defendeu Jensen Huang, descrevendo-o como um 'honourable guy.

Asked whether he should have acted after reportedly receiving an intelligence briefing about the allegations, Trump said, “No, I don’t think so.”.

Meanwhile, ⁠⁠⁠⁠Chinese Ministry of Foreign Affairs spokesperson ⁠⁠⁠⁠Guo Jiakun on Monday said the “so-called ⁠⁠⁠⁠Chinese spy ⁠⁠⁠⁠narrative” was unsubstantiated.

Jensen Huang, who is seen as a close adviser to Trump on the AI trade, has repeatedly pushed to loosen chip sales restrictions to China.

The scandal threatens to intensify tensions between Washington and Beijing over access to the powerful semiconductors needed to develop advanced AI systems. Semiconductors are needed to run nearly all electronics from smartphones to cars and military equipment.

Nvidia is a central player in that competition, supplying chips used by major US technology companies to train and operate AI models. It was until October 30 the most valuable company in the world.

Washington restringiu as exportações de seus processadores mais avançados para a China por motivos de segurança nacional. Os chips de GPU Blackwell, de última geração da Nvidia, estão proibidos de exportação para a China.

The US has also clarified that restrictions apply to Chinese-owned companies operating outside China amid concerns that overseas subsidiaries could provide a route around export controls.

However, in December, Trump said Nvidia could sell its H200 chip to China, marking a major easing of US export restrictions. The H200, while not Nvidia’s top chip, is roughly six times more powerful than the model previously approved for sale to China, the H20.

As alegações envolvendo Megaspeed, portanto, poderiam aumentar a pressão sobre Washington para examinar os clientes estrangeiros da Nvidia e reforçar os controles sobre as remessas de chips.

However, Chinese companies have continued developing competitive AI systems despite restrictions on advanced US chips.

Em janeiro, o lançamento do modelo de IA da startup chinesa DeepSeek fez manchetes depois que foi construído usando apenas uma fração do dinheiro que seus concorrentes haviam gasto em seus próprios modelos de IA.

Share prices of US tech companies plummeted.

China has advantages in other areas of the AI supply chain, most notably in the production of critical rare earth minerals used in advanced technology. It also generates more than twice as much electricity as the US, giving it access to the vast amounts of relatively cheap power needed to operate AI data centres.
