China Rejects Nvidia H200 Chips Despite U.S. Approval: Semiconductor Trade Friction Escalates

On May 15, reports surfaced that the U.S. approved sales of Nvidia's H200 advanced AI chips to 10 Chinese companies, a reversal of months of strict controls. However, China immediately rejected the offer and redirected investment toward domestic alternatives. This pivot contradicts the assumption held by many chip investors: that easing export restrictions would unlock huge TAM expansion and capex spending. Instead, geopolitical deterioration is forcing both sides to build redundant supply chains, destroying unit economics.

The H200 approval itself was striking: it came during Trump's Beijing visit, signaling a brief diplomatic thaw. Yet within hours, Chinese officials made clear they have no interest in buying U.S. chips at any price. State media and official statements emphasized self-sufficiency in semiconductors as a national priority. This is not opportunistic procurement; it is strategic de-coupling. Nvidia and AMD both sold off sharply Friday, with Nvidia down 2.2 percent and AMD down 3.3 percent by close. The broader semiconductor index (SOXX) underperformed, weighed down by the realization that China export assumptions embedded in Q1 guidanceCompany-issued forecasts of future financial performance. may need to be revised lower.

Jensen Huang, Nvidia's CEO, said earlier in the week that energy demand for AI will increase one-thousandfold, justifying massive capex and a structural bull case. But that thesis assumes global fragmentation is reversible and that geopolitics doesn't permanently bifurcate the market. China's rejection of H200 chips suggests the opposite: decoupling is hardening, and each side will tolerate lower margins and higher costs to avoid dependence. For Nvidia, this means the addressable market in China shrinks from 'all enterprises' to 'those approved by Beijing.' For AMD, the same dynamic applies.

Market participants are debating whether this is a negotiating tactic or a structural shift. Some argue China is signaling resolve to extract concessions later. Others see it as confirmation that U.S.-China competition is now zero-sum in semiconductors. Either way, the near-term damage to sentiment is real: earnings calls next week will face questions about China revenue guidanceCompany-issued forecasts of future financial performance. and capex cycle assumptions, likely leading to conservative guidance and stock pressure.
