Abstract:In the note it is proved that, for an arbitrary action of a semisimple group G on an affine variety X, there is a positive integer n such that the diagonal action 
$$G:X times X times X times cdot cdot cdot times X$$
(m copies) is stable for any 
$$m geqslant n$$
.
Keywords:semisimple group  affine variety  stable action  generic orbit
