Electromagnetic form factor, especially its asymptotic behavior for large momentum transfer ($Q^2$), of kaon provides crucial insight into the partonic structure of a Nambu-Goldstone boson in strong interaction. Studies of the electromagnetic form factor of kaon up to $Q^2 \sim 6$ GeV$^2$ are underway at the ongoing JLab12 experiment, and its measurements in an extended range of $Q^2 \sim 9 - 30$ GeV$^2$ are planned at the future Electron Ion Collider (EIC). For the first time, we will present results for the kaon electromagnetic form factor in the range of $Q^2 \sim 2 - 10$ GeV$^2$ from state-of-the-art lattice QCD calculations carried out using physical values of up, down and strange quark masses. These results will provide benchmark QCD predictions for model-based studies and the experimental measurements, in particular at the boundaries between the JLab$12$ and the EIC.
