An $8 trillion-dollar discovery 17,000 ft underwater (Ad)

A strange rock pulled from the ocean floor may hold the key to a $16 trillion resource boom. Inside it: materials critical for AI chips, EV batteries, smartphones, and advanced weapons systems. While few people know about these metals, global powers—including the U.S., China, and Russia—are racing to secure them. And one tiny public company, recently backed by the U.S. government, holds mining rights to over 340 million tons… and near-monopoly access to the richest zone.tc pixel
