The z value, or redshift value, for an object on our cosmic light horizon is theoretically infinite. This is because the cosmic light horizon represents the furthest distance from which light has had time to reach us since the beginning of the universe. As objects move away from us due to the expansion of the universe, their light is redshifted. At the cosmic light horizon, this effect is maximized, leading to an infinite redshift.
