Nvidia shares rose 1.2 per cent in after-hours trading after US President Donald Trump made the announcement on Truth Social, having closed 3.16 per cent higher after Semafor first reported the possibility of approval.
Trump said that he had informed President Xi Jinping of China, where Nvidia's chips are under government scrutiny, about the move and he "responded positively," according to Trump's post.
Trump said the US Commerce Department was finalising details of the arrangement and the same approach would apply to other AI chip firms such as Advanced Micro Devices and Intel .
"We will protect National Security, create American Jobs, and keep America's lead in AI," Trump wrote on Truth Social.
"NVIDIA's US Customers are already moving forward with their incredible, highly advanced Blackwell chips, and soon, Rubin, neither of which are part of this deal."
Allowing the shipments could signal a friendlier approach to China, after Trump and Xi brokered a truce in the two countries' trade and tech war in Busan, South Korea in late October.
Administration officials consider the move a compromise between sending Nvidia's latest Blackwell chips to China, which Trump has declined to allow, and sending China no US chips at all, which officials believe would bolster Huawei's efforts to sell AI chips in China, the person familiar with the matter said.
China hawks in Washington are concerned that selling more advanced AI chips to China could help Beijing supercharge its military, fears that had first prompted limits on such exports by the Biden administration.
Earlier media reports of H200 export approvals drew sharp criticism from Senator Elizabeth Warren, a Massachusetts Democrat who supported a bipartisan effort to reserve powerful US AI chips for US firms.
"After his backroom meeting with Donald Trump and his company's donation to the Trump ballroom, (Nvidia) CEO Jensen Huang got his wish to sell the most powerful AI chip we've ever sold to China," Warren said in a statement.
"This risks turbocharging China's bid for technological and military dominance and undermining US economic and national security."
The H200 chip, unveiled two years ago, has more high-bandwidth memory than its predecessor, the H100, allowing it to process data more quickly.
According to a report released on Sunday by the non-partisan think tank the Institute for Progress, the H200 would be almost six times as powerful as the H20, the most advanced AI semiconductor that can legally be exported to China, after the Trump administration reversed its short-lived ban on such sales this year.
Export of the chip would allow Chinese AI labs to build AI supercomputers that achieve performance similar to top US AI supercomputers, albeit at higher costs, the report also said.
Faced with Beijing's muscular use of export controls on rare earth minerals, which are critical for producing a raft of tech goods, Trump this year threatened new restrictions on tech exports to China, but ultimately rolled them back in most cases.
China's cybersecurity regulator summoned Nvidia to a meeting to explain whether its H20 AI chip had any backdoor security risks, an allegation Nvidia has denied, Reuters reported in August.
