Resolves YES if the Trump administration officially announces a floor price for samarium 3N (99.9% purity) exceeding $60 per kilogram (USD/kg) as part of Project Vault under Section 232 critical minerals initiatives or strategic reserve mechanisms; resolves NO if at or below $60/kg or no floor price is announced for samarium. Resolution source is the first official White House, Department of Commerce, or U.S. Trade Representative publication specifying the samarium floor price (e.g., press release, Federal Register notice); market stays open until this announcement. Samarium (Q1819) is a vital rare earth for aircraft engines, magnets, and defense amid 90% Chinese supply dominance; current oxide price is ~$58/kg (Feb 2026), with suggested floor of $60/kg (1.5-2x multiple) to mitigate volatility and boost U.S. production. Project Vault's $12B rare earth stockpile launch signals aggressive supply chain protection, but exact floors remain unannounced; threshold reflects uncertainty between conservative ~1.5x and aggressive 2x levels.
