$\alpha_s$ extractions from CMS (status and plans)

Numerous extractions of the strong coupling constant have been performed at hadron colliders, in particular from jet cross sections. The latest results achieved by the experiments at the $ep$ collider HERA, at the $p\bar{p}$ collider Tevatron, and at the $pp$ collider LHC are reported with emphasis on the CMS experiment for the latter. Future prospects for precision determinations of $\alpha_s(M_Z)$ and for testing the running of the strong coupling beyond the TeV range are discussed.
