First principles’ calculations of the Bjorken-x dependence of hadron structure have been a long-standing challenge for QCD. Last year marked a significant milestone: the first determinations of parton distribution functions, which capture the longitudinal momentum structure of fast-moving hadrons, from lattice calculations at physical pion masses. There has also been significant progress in our understanding of the theoretical frameworks underpinning these calculations, although not all sources of systematic uncertainty have been fully explored. I review the various approaches to extracting x-dependent hadron structure from lattice QCD, survey recent results in both the meson and baryon sectors and highlight some of the implications for our understanding of hadron structure in the near future.
