Meet the 10 Market Stars Behind Millionaire-Making in 2025

6. TMC the metals company Inc. (NASDAQ:TMC)

TMC the metals company soared by 450.89 percent in 2025, thanks to a flurry of catalysts, including the surging demand for its mined metals, as well as the Trump administration’s confirmation that it would start to review its deep-sea mining intent this month.

TMC the metals company Inc. (NASDAQ:TMC) was notably trading just around the $1 level a year ago, until it announced in April its official intent with the US government to mine in the international seabed—a move that significantly propelled its share prices higher but also earned the ire of members of the International Seabed Authority (ISA).

According to the ISA, of which Canada is a member, TMC the metals company Inc. (NASDAQ:TMC) bypassed the agency for submitting its deep-sea mining intention with the US—a non-ISA member—while originally being a Canadian company.

For its part, the listed firm said that the submission was made through its US subsidiary.

Meanwhile, the US government last month confirmed that it would review the listed firm’s application through a series of public hearings beginning this January.

In other developments, TMC the metals company Inc. (NASDAQ:TMC), also benefited from the electric vehicle and energy boom, which has accelerated the buildout of more power infrastructures. This, in turn, drove stronger demand for battery and industrial metals such as copper, nickel, cobalt, and manganese, which are the key focus of its mining operations.
