Recent cross-section measurements of top pair production, single-top production, and rare top associated production by the CMS and ATLAS collaborations are presented. These results include the very first Run III results at $\sqrt{s}$=13.6 TeV as well as most precise inclusive and differential top-quark cross sectional measurements and observations to date in Run II and $\sqrt{s}$=13 TeV. This includes the first observation of four-top production in both ATLAS and CMS and the first evidence of tWZ production. This diverse set of measurements showcase very sensitive results beyond historical expectations that are driven by improved analysis strategies and techniques on the parts of both experiments. Results are generally in good agreement with Standard Model expectations with some excesses, motivating continued exploration in Run III and the HL-LHC as well as improved theoretical calculations and modeling strategies.
