If China lets Nvidia take new chip orders, Micron, Broadcom and Marvell could gain too

The link fails if China's review leads to no real purchase approvals. It also fails if approvals cover only weakened chips such as the H20. Watch Nvidia's next earnings call or guidance update. If Nvidia says Chinese orders remain small despite the policy review, the case for its suppliers falls apart.

This headline may be diplomatic signaling rather than a coming policy change. China has floated chip access as a bargaining chip before without follow-through. Any approvals may cover only weakened chips such as the H20. The weakest step is that Chinese cloud giants would order enough to strain US suppliers. If orders are small or spread out, the extra demand for memory and networking companies never arrives. Nvidia confirming that the H20, and not the H100 or H200, is the approved chip would be a warning sign for these suppliers.

The closest example is 2019-2020, when hopes rose that the Huawei ban would be reversed. Each hopeful US-China trade headline lifted the whole chip supply chain, beyond the companies named. Applied Materials, Lam Research and KLA rose in the weeks after optimism about the Phase 1 trade deal in December 2019, though none was a named winner. Investors first focus on the headline company, then move to its suppliers as analysts work through the chain. Similarly, when the big cloud companies stepped up AI spending in 2023, Micron Technology (MU) lagged Nvidia's first rally, then rose as shortages of high-bandwidth memory became clear. A Chinese return would shorten that lag.
