US Approves H200 Chip Sales to 10 Chinese Firms; NVDA Rallies on Export Win

In a significant policy reversal, the US approved NVIDIA's sale of advanced H200 artificial intelligence chips to 10 Chinese companies, lifting a major export constraint that had shadowed semiconductor valuations for months. NVIDIA shares surged 4.4% on the news, and the broader semiconductor complex (AMD, AVGO, SMCI) benefited from the catalytic relief. China historically represented approximately 25% of NVIDIA's total revenue, making the approval a material rerating of forward earnings visibility.

The geopolitical calculus appears to have shifted. The White House rationale framed the move as part of "wholesome discussions" with Beijing on AI safety standards, suggesting the administration believes measured engagement serves US technological leadership better than blanket bans. This aligns with broader US-China summit messaging on stabilization of bilateral ties. Traders immediately repriced the scenario: if H200 exports remain open, NVIDIA's addressable TAM expands meaningfully, and the company's 5.5-trillion-dollar market cap (a record in May 2026) could attract fresh institutional capital on earnings upside.

However, the approval comes with embedded political risk. The export license remains subject to revocation if geopolitical tensions escalate, and Taiwan remains a flashpoint in negotiations. Defense and chip-export hawks in Congress view unrestricted AI chip sales to China as a strategic gift, particularly as Beijing races to close the inference gap with US models. Additionally, the approval may face renewed scrutiny if US-China trade talks deteriorate or if Beijing accelerates military spending on AI systems.

For semiconductor players, the window may be temporary. Arista Networks (ANET) noted supply-chain constraints from legacy chip suppliers (e.g., Broadcom), and AMD guidanceCompany-issued forecasts of future financial performance. on China channel demand remains cautious. The narrative hinges on durationBond price sensitivity to interest rate changes.: if China can purchase NVIDIA chips indefinitely, capex tailwinds extend multi-year. If the approval expires in 6-12 months, demand panics and inventory cycles could amplify downside.
