SemiAnalysis's Dylan Patel: Blocking Lithography Equipment Slows China's AI More Than Banning Chip Exports

The SemiAnalysis team discusses AI export control strategies following Jensen Huang's resignation. Dylan Patel argues for a core strategy: allow Chinese firms to remotely rent US computing power (acting as a cut-off 'kill switch' while generating massive profits) and simultaneously block the export of DUV lithography equipment via the MATCH Act, forcing China into a structural disadvantage in scale competition.

On November 13, 2026, three members of the semiconductor research firm SemiAnalysis—Jordan Schneider, Dylan Patel, and Jordan Nanos—recorded an emergency podcast regarding Jensen Huang's resignation as CEO of Nvidia. During their discussion on policy directions, Dylan Patel proposed a strategic framework that contradicted the prevailing mainstream thinking in Washington at the time: rather than banning Chinese access to remote US computing power, the focus should be on blocking the equipment required to manufacture chips.

Patel's core logic is to 'flip the table.' He uses a jigsaw puzzle analogy to explain: if you remove one piece from the top of the supply chain (such as banning a specific chip export), China will specifically target and overcome that single piece; but if you flip over the entire puzzle board, the difficulty level changes completely. Specifically, instead of banning the chips themselves or restricting model access, it is more effective to prevent companies like ASML from selling DUV lithography equipment to China. Without this equipment, China cannot mass-produce advanced chips, regardless of how it designs architectures or optimizes algorithms.

The second pillar of this strategy is to permit, rather than prohibit, remote computing access. Patel's game-theory reasoning suggests that if companies such as Alibaba, ByteDance, and Moonshot must rent computing power from US cloud service providers, the United States gains three distinct advantages. First, Chinese data may be processed within the US, allowing intelligence agencies access. Second, if tensions escalate, the US can cut off access at any moment—a 'kill switch.' Third, every megawatt of computing deployed outside China generates massive profits for the US ecosystem: Nvidia earns approximately $7 million per deployment, with cloud service providers adding another $7 million to $10 million.

Patel argues that cutting off remote access would instead incentivize smuggling, accelerate the development of China's domestic chip industry (which was going to happen anyway), and eliminate China's economic incentive to maintain the status quo of manufacturing electronics for American companies. He cites Nvidia's largest PCB supplier as a Chinese company as an example. Maintaining the current situation gives China a financial reason to continue cooperation.

However, this argument faces pushback from within the same podcast. Jordan Schneider points out that parts of the Chinese decision-making apparatus (potentially including Xi Jinping himself) are deeply embarrassed by how desperately domestic enterprises want to import GPUs. Even when Trump offered to sell them, the Chinese government hesitated to allow these companies to make purchases. This implies that the RASA Act might provide China with a political excuse to 'force self-reliance,' rather than triggering the comprehensive economic war Patel fears. Schneider also questions whether China has the capacity or willingness to launch a full-scale retaliation—given its slowing economic growth, unemployment rates reaching 20%, and the fact that Trump continues to push forward despite the high costs of the war in Iran, suggesting the US government's pain tolerance may be underestimated.

Patel responds that every escalation-retaliation cycle in past US-China trade frictions ultimately led to compromise rather than total decoupling, because neither side could afford the cost of broken supply chains. He acknowledges he is arguing from the position of a 'devil's advocate' and concludes that one can be a hawk and still oppose the RASA Act, but it is difficult to oppose the MATCH Act.

From an industrial investment perspective, Patel's framework implies that if the MATCH Act passes, lithography equipment vendors like ASML will face structural risks to their revenue from China; meanwhile, Nvidia, cloud service providers, and compute rental platforms could continue to profit from permitted remote access. This judgment assumes that the US government indeed chooses the equipment blockade path over total decoupling, and that China does not retaliate with equivalent leverage using rare earths, market access, or other tools.
