White House Tightens AI Tech Controls, Halts Nvidia’s China Shipments

TLDRs;

• The White House has barred Nvidia from selling its advanced Blackwell AI chips to China.
• Nvidia’s China revenue plunged from $17 billion to $2.8 billion amid escalating export restrictions.
• U.S. and allied cloud providers will now receive redirected Blackwell chip supplies.
• The move cements the U.S.-China divide in the global AI semiconductor competition.

In a major escalation of U.S. technology export restrictions, the White House has confirmed it will block Nvidia from selling its most advanced artificial intelligence chip, the Blackwell, to China. The move underscores the Trump administration’s determination to maintain a technological edge over Beijing in the AI and semiconductor sectors.

White House spokesperson Karoline Leavitt made the announcement during a November 4 press briefing, saying the administration “does not plan to allow sales of the Blackwell chip to China at this time.” The decision follows months of speculation about whether a downgraded version of the chip might still reach Chinese customers.

President Donald Trump himself had hinted at possible leniency earlier this year, suggesting that limited exports might be permitted under strict conditions. However, in recent weeks, the administration shifted tone, arguing that advanced AI chips should be reserved for U.S. companies and trusted allies. Trump also noted that he did not discuss the issue with Chinese President Xi Jinping during their recent meeting in South Korea.

Nvidia’s China Revenue Nosedives

The renewed export restrictions come at a sensitive moment for Nvidia, whose exposure to the Chinese market has already taken a hit. The company’s China-related revenue fell from $17 billion last fiscal year, about 13% of its total sales, to $2.8 billion in the most recent quarter, according to industry data.

Before the latest policy change, Nvidia’s H20 chip, a lower-performance version of its flagship AI hardware, was developed to comply with earlier U.S. export limits. But even those sales have since evaporated. Reports indicate that Nvidia recorded roughly $4.5 billion in charges tied to the H20 project during the first fiscal quarter, with no subsequent sales into China in Q2.

As a result, Nvidia’s once-dominant position in China’s AI chip market, estimated at nearly 95% share, has fallen to near zero. Analysts say the latest White House move effectively cements that decline, at least for the foreseeable future.

Focus Shifts to U.S. and Allied Markets

With China now cut off from its most advanced AI processors, Nvidia is expected to redirect supply toward U.S. cloud providers and allied countries. Industry forecasts show that the company shipped around 6 million AI chips over the past year and is projected to deliver 14 million more in the next five quarters, almost all to Western markets.

These chips are vital to powering the data centers of major cloud providers, which have seen capital expenditures rise 53% year-over-year in early 2025. The demand surge is being driven by hyperscalers, the world’s largest internet and cloud platforms, racing to expand their AI infrastructure.

Nvidia, for its part, is doubling down on U.S. manufacturing. The company is constructing over one million square feet of new production space in Arizona and Texas, part of a broader plan to invest up to half a trillion dollars in AI infrastructure over the next four years.
