We discuss the status and some recent results of the CMS experiment at the LHC. The performance of the detector is assessed using a luminosity of $\approx 5~\mathrm{fb}^{-1}$ recorded in the first part of the 2017 data-taking period. Run~2 physics studies use data collected at a center-of-mass energy of $\sqrt{s}=13~\mathrm{TeV}$, corresponding to an integrated luminosity of $36~\mathrm{fb}^{-1}$. Highlights from studies in the Higgs sector are the first observation of its decay into tau leptons by a single experiment, the most precise measurement of its mass, $\mathrm{m_H} = 125.26 \pm 0.21~\mathrm{GeV}$ and a first search for the $\mathrm{H}\to\mathrm{b\overline{b}}$ decay in a phase space region that is sensitive to the gluon-fusion production mechanism. In the electroweak sector, CMS provides the currently most precise measurement of the effective weak mixing angle at the LHC: $\sin\theta^{\rm lept}_{\rm eff} = 0.23101\pm 0.00052$, using an integrated luminosity of $\approx 20~\mathrm{fb}^{-1}$ at $\sqrt{s}=8~\mathrm{TeV}$. Other CMS highlights of this conference are new stringent limits on di-Higgs production and improved searches for dark matter and electroweakinos.
