DOE NIDC supplies helium-3 on a quotation basis rather than through a continuously published price benchmark. The displayed value is an indicative commercial reference, not an assessed spot price.
Helium-3 is included as a terrestrial reference for prospective lunar isotope extraction. It provides market context for a resource with direct lunar relevance and emerging space-to-Earth commercial activity.
Helium-3 is a thin, specialised isotope market rather than a continuously traded commodity. The displayed indicative value should not be interpreted as an assessed spot price. No historical price series or daily percentage change is shown without a defensible public benchmark.
