Goworld and Goldenmax International jointly rejected online claims that their products had entered Nvidia or Huawei supply chains after sharp share-price gains triggered abnormal-trading warnings on Sept. 13. Goworld said it has no products supplied to Nvidia and that its 800G and 1.6T optical-module companion PCBs remain in follow-up research and development, without scaled supply or revenue. Goldenmax said it has never contacted or cooperated with Nvidia or Huawei, has identified no AI-server or computing-power applications, and that its high-frequency, high-speed copper-clad laminates remain in laboratory development or customer sampling. Goworld's closing-price deviation exceeded 20% over two consecutive trading days, while Goldenmax reached 20% over Sept. 10 and 11. The announcements highlight the gap between AI-infrastructure market speculation and the companies' disclosed commercial progress.
