A small-x helicity evolution has been derived in 2016–2018 and re ceived an important modification in 2022. This article discusses its general framework and summarizes recent theoretical developments, including the asymptotic behaviors of helicity PDFs and g1 structure function at small x. The latest fits to various polarized scattering data are also discussed. The results from this research program will provide important theoretical inputs for the future polarized small-x measurements at the EIC.
