There are plenty of tiny, zero-revenue stocks out there claiming to have vast reserves of untapped lithium ore. These are the crazy Uncle Joes of the market. Smile, nod, and then turn your attention to the suppliers with real market share. Albemarle Corp. (NYSE: ALB), Sociedad Quimica y Minera de Chile (NYSE: SQM), and FMC Corp. (NYSE: FMC) own a combined 70% of the global lithium market. China's Tianqi Lithium owns another 16%. These diverse specialty chemical companies buy up the rights to unmined lithium and convert it into more refined grades that are suitable for downstream customers, such as battery manufacturers.
