Recent Price History

Rubidium is priced at approximately $12,000-15,000/kg, reflecting its extreme scarcity and specialized production. The market is one of the smallest of any element (~4 tonnes/year) with no public price benchmarks. All sales are through private contracts. Rubidium is so scarce and the market so small that it is barely a commodity in the traditional sense.
