  Abstract A measurement of CP asymmetry in D-0 -> (KSKS0)-K-0 decays is reported, based on a data sample of proton-proton collisions collected with the LHCb detector in 2024 at a centre-of-mass energy of 13.6TeV, corresponding to an integrated luminosity of 6.2 fb(-1). The D-0 -> K-S(0)pi(+)pi(-) decay is used as calibration channel to cancel residual detection and production asymmetries. The time-integrated CP asymmetry for the D-0 -> (KSKS0)-K-0 mode is measured to be A(CP) (D-0 -> (KSKS0)-K-0) = (1.86 +/- 1.04 +/- 0.41)%, where the first uncertainty is statistical, and the second is systematic. This measurement represents the most precise single-experiment determination of this quantity to date.
