AI suppliers just surged. Now a proposed U.S. ban on Chinese optical modules adds a policy shock to the $1 trillion trade.

CoreWeave, AAOI, AXT and Nebius rose 11%–19%, but Goldman said the buying was driven almost entirely by short covering. Reuters now reports that Washington is drafting a ban on new Chinese optical transceivers for data centers, putting Innolight under pressure and forcing a rethink of U.S. suppliers and cloud costs.

As of 6:04 PM Beijing time, AXTI was up 6.74% pre-market and AAOI 5.16%. Tonight brings AMD and SpaceX earnings; SNDK, WDC and AAOI follow this week, alongside U.S. payrolls and China CPI.
