  We study the $\Phi^3_2$-measure in the infinite volume limit. This is the
invariant measure for several stochastic partial differential equations
including the parabolic and hyperbolic $\Phi^3_2$-models. In the large torus
limit, we observe a concentration phenomenon of the $\Phi^3_2$-measure around
zero, which is the single minimizer of the corresponding Hamiltonian for any
fixed torus size. From our sharp estimates for the partition function, we
obtain a triviality result for the $\Phi^3_2$-measure on infinite volume: the
ensemble collapses onto a delta function on the zero field.
