If sufficiently stable, strange quark nuggets (SQNs) could survive to the present epoch and contribute to the dark matter density. We analyze formation conditions, stability criteria, relic abundance estimates, and observational constraints. The framework remains fully compatible with </span><span>Λ</span><span lang="EN-US">CDM cosmology and does not modify inflationary dynamics or the standard expansion history.</span></p>
