One tiny company just cracked Google’s $19B problem (Ad)

For decades, this “AI metal” was trapped in labs, too slow and expensive to ever reach mass production. Then an MIT team cracked the code… dropping the cost from $63,000 to just 90 cents per gram. Now, one US-based factory is gearing up to supply the AI, aerospace, and EV industries with the one material they can’t continue to grow without. Only one company controls it, and its stock is still flying under Main Street’s radar.tc pixel

See why the race for supply has already started.
