The China chip story keeps landing on $NVDA, and it won't go away. A US official now alleges Chinese AI apps ran on banned Nvidia chips. Same fear that's shadowed the stock all year. The timeline is what makes it stick: Weeks ago, Nvidia cut its Asia buyer list in half to stop chips leaking into China (FT). Ten days ago, chip stocks slid on the same worry. SK Hynix fell 15% in one session. Back in March, the DOJ broke up a ring smuggling advanced Nvidia chips into China, labelled as 'adapters' (thewirechina). Nvidia's side: CEO Jensen Huang says there's 'no evidence of any AI chip diversion' into China. Where the stock sits: $212.06, close to its $236.54 record but inside a wide year (low of $164.27). A typical day moves about $7.26. The real question isn't the headline. It's how far this allegation travels through Washington. Not advice, markets carry risk.
