  Building on a previous conjecture, we argue that the holographic dual of the
light-front vacuum state of a superconformal field theory quantized in the
front form of dynamics contains the Kaigorodov spacetime, which is nothing but
a pp-wave propagating in AdS. Evidence in favor of this conjecture is
presented. In particular we verify the matching of global symmetries and
discuss the contribution of the zero mode sector in both sides of the
correspondence.
