Abstract: Using $e^+ e^-$ collision data collected with the BESIII detector at center-of-mass energies between $4.128$ and $4.226$ GeV, corresponding to an integrated luminosity of $7.33~{\rm fb}^{-1}$, the inclusive branching fractions of the decays $D_s^+ \to ηX$ and $D_s^+ \to η^\prime X$ ($X$ denotes any possible particles) are measured to be $(30.72 \pm 0.90 \pm 0.46)\%$ and $(12.30 \pm 0.94 \pm 0.37)\%$, where the first uncertainties are statistical and the second systematic. The results are consistent with the previous CLEO measurements, with precision improved by factors of 2.8 and 1.9 for $D_s^+ \to ηX$ and $D_s^+ \to η^\prime X$, respectively.
