, and their antiparticles was measured in inelastic proton–proton (pp) collisions at a center-of-mass energy of 
= 13 TeV at midrapidity (
) as a function of transverse momentum (
) using the ALICE detector at the CERN LHC. Furthermore, the single-particle distributions of , , and 
in inelastic pp collisions at 
TeV are reported here for the first time. The distributions are studied at midrapidity within the transverse momentum range 
GeV/c, depending on the particle species. The spectra, integrated yields, and particle yield ratios are discussed as a function of collision energy and compared with measurements at lower and with results from various general-purpose QCD-inspired Monte Carlo models. A hardening of the spectra at high with increasing collision energy is observed, which is similar for all particle species under study. The transverse mass and 
scaling properties of hadron production are also studied. As the collision energy increases from = 7–13 TeV, the yields of non- and single-strange hadrons normalized to the pion yields remain approximately constant as a function of , while ratios for multi-strange hadrons indicate enhancements. The 
-differential cross sections of , 
and 
(
) are compared with next-to-leading order perturbative QCD calculations, which are found to overestimate the cross sections for and () at high .
