China Spurns US Chip Sales: NVDA, AMD Down 2-3% as Beijing Bets on Domestic Semiconductors

Beijing just threw a curveball at Wall Street's semiconductor bulls. Even as the US approved sales of Nvidia's H200 AI chips to ten Chinese companies, China's government signaled it will not buy them, choosing instead to accelerate domestic chip manufacturing. This is not a surprise reversal; it is a strategic shift. For two years, semiconductor investors have assumed China would remain a growth driver for US chip exports, a key variable in NVDA and AMD bull cases. That assumption just got harder to defend.

The move reflects deeper geopolitical fracture. Trump administration approved the H200 sales as a bone to Boeing (which secured a China aircraft order during the Beijing summit) and as a soft hand on trade. But Beijing has clearly decided that relying on US chips is a strategic vulnerability. The government has poured billions into SMIC and other domestic fabs, and the message now is: we will not buy your advanced chips; we will build our own. Nvidia shares fell 2.2 percent Friday on the news, while AMD dropped 3.3 percent, both underperforming the broader tech selloff. The decline was not about earnings disappointment; it was about growth assumptions evaporating.

Implications ripple across semiconductor supply chains. If China cuts Nvidia out of its AI capex budget, that is tens of billions in demand destruction that was factored into bull cases from $NVDA to Broadcom (AVGO) to memory makers like Micron (MU). US chip companies now face a binary choice: re-focus capex on non-China markets (Europe, India, APAC) or accept lower growth. AMD and others have exposure to data-center and consumer-facing supply chains that are more globally distributed, but the message is clear: China is no longer a reliable export market for US semiconductor cutting edge. This also benefits Samsung and SK Hynix, which have positioned fabs in non-US jurisdictions.

The narrative compounds semiconductor sector weakness. Coupled with higher yields (which depress capex forecasts for data-center customers), semiconductor stocks face a double bind: lower China demand and higher discount rates. Investors who were chasing NVDA at 20 percent gains in early May now face an earnings re-cut risk if China guidanceCompany-issued forecasts of future financial performance. disappoints. The sector's near-term catalyst is NVDA earnings next week (May 21); any cautious China commentary will trigger another leg down.
