(According to the barrel theory, indium phosphide is the decisive short board restricting hardware expansion in the global AI industry chain. Changxin Technology's surge upon listing on A-shares and Korean memory makers' expansion followed by sharp drops seem contradictory, but together they point to the deepest supply contradiction in the AI computing power industry chain—indium phosphide (InP) substrates are the 'shortest board' determining the upper limit of all hardware expansion.) Tomorrow, China's AI hardware and A-share's only indium phosphide substrate materials companies—Xingye Technology, Yunnan Germanium, Suqian Liansheng, Xiandao Jidian, and Aiai Precision—are bound to surge. On July 30, InP substrate manufacturer $AXT(AXTI)$ disclosed an unusual long-term agreement. ...
