TMC shares surge 20.92% intraday as U.S. alliance efforts to secure critical minerals for AI drive investor interest in deep-sea mining.

TMC the Metals Company surged 20.92% intraday amid renewed U.S. focus on securing critical minerals for AI applications. The rally followed reports that the White House is seeking alliances with eight nations to reduce reliance on China for minerals like cobalt, nickel, and manganese, which the company targets through deep-sea mining. Despite no direct corporate announcements, the stock’s sharp reversal from a prior 9.7% decline was driven by investor optimism over policy tailwinds and the strategic value of TMC’s pre-commercial operations in the Clarion Clipperton Zone. The move aligns with broader market speculation on U.S. onshoring initiatives and heightened demand for metals critical to energy storage and semiconductor manufacturing.
