Rubidium Price per kg (United States)

Over the past 12 months it has ranged from $24,530 to $24,530 per kg contained.

Over one year the price has changed +7.1%.

Rubidium (Rb) has a very small market, much of it in rubidium atomic clocks, the compact frequency standards used in satellites, telecoms networks and defence systems. It is also used in research, from quantum computing to ultra-cold atom physics, and in specialty glass and photoelectric cells.

Other uses

• Rubidium-82 for cardiac PET imaging
• Specialty glass and fibre optics
• Catalysts
• Photocells and vapour cells for sensors

Rubidium is a by-product of cesium and lithium mining from a few pegmatite deposits, and its market is small and illiquid. Demand from atomic clocks, research and specialty glass is steady, and prices are negotiated privately between a handful of suppliers and buyers.

What moves the price

• Output from the few cesium and lithium pegmatites
• Atomic clock and quantum research demand
• Specialty glass and photocell demand
• Supplier pricing

Rubidium has a tiny market, supplied by a few producers to a few buyers, and its price rarely changes.

As of October 2026, the Stockatomics benchmark price is $24,530 per kg contained.

Rubidium is a by-product of cesium and lithium mining from a few pegmatite deposits, notably in Canada and Africa, and production data are scarce. China is believed to be the main producer of rubidium compounds.

Rubidium is on the US critical minerals list. Volumes are tiny, deposits are few, and timing and research uses have no ready substitute.

Stockatomics publishes a US benchmark price for rubidium in US dollars per kg contained, reading as of October 2026. The price is for rubidium metal. The market is tiny, so the price moves less often than those of exchange-traded metals.
