US-China AI Deal Unblocked: NVDA Gains China Market Access; Capex Cycle Accelerates

During his two-day Beijing summit with Xi Jinping, President Donald Trump reportedly agreed to ease restrictions on advanced chip exports to China, marking a significant reversal of the tech-war stance that had constrained Nvidia's revenue for years. Social media chatter suggests that an agreement on Nvidia chip sales could restore 25% of NVDA's total revenue, a massive unlock for the semiconductor giant and its supply chain. US Trade Representative Jamieson Greer signaled cautious optimism on bilateral trade rebalancing, with progress on agriculture purchases and rare earths cooperation, suggesting the summit delivered tangible commerce wins beyond just chip access.

Nvidia shares rallied on the announcement, with Nvidia CEO Jensen Huang spotted in Beijing during the talks, underscoring the symbolic importance of the US-China chip accord. The broader AI capex narrative benefits from expanded addressable markets; if Chinese data centers and AI labs can legally purchase NVDA GPUs again, capex spend in China accelerates, validating the thesis that global AI infrastructure buildout is just entering its growth phase. Broadcom (AVGO), Advanced Micro Devices (AMD), and Arm Holdings (ARM) also enjoy tailwinds as the supply chain expands to serve previously off-limits markets. CoreWeave's recent $21B agreement with Meta for long-term inference capacity signals that AI capex is transitioning from training to inference, a multi-year cycle that benefits the entire semiconductor ecosystem.

Implications extend to US-China trade dynamics and strategic tech competition. If chip exports to China are normalized, the US loses one of its few leverage points in trade negotiations and geopolitical standoffs. Defense contractors and allies in Taiwan and South Korea may interpret the move as a signal of reduced US commitment to tech containment, potentially emboldening Chinese AI advancement and accelerating the timeline for parity in LLM capabilities. Additionally, if China gains unfettered access to NVDA H100s and H200s, the US strategic advantage in AI-powered military and intelligence applications narrows.

Bears note that any US-China chip deal is politically fragile and reversible at a moment's notice; Trump's stated goal of "America First" could flip if political winds shift or if China exploits chip access for military AI applications. Furthermore, NVDA's China revenue was a much smaller piece of the capex story pre-restrictions; the restoration of access is a nice-to-have, not a make-or-break driver. Consensus already prices in robust global AI capex across US, EU, and APAC without China. Lastly, Taiwan's TSMC and South Korea's Samsung remain the true chokepoints for advanced chip production; export policy shifts do not change fundamental supply constraints.
