We propose an emergent cosmological model rooted in the asymptotically safe antiscreening behavior of the Newton constant at Planckian energies. Distinguishing itself from prior approaches, our model encapsulates the variable nature of $G$ through a multiplicative coupling within the matter Lagrangian, characterized by a conserved energy-momentum tensor. The Universe emerges from a quasi--de Sitter phase, transitioning to standard cosmological evolution post-Planck era. Our analysis demonstrates the feasibility of constraining the transition scale to nearly classical cosmology using cosmic microwave background data and the potential to empirically probe the antiscreening trait of Newton's constant, as predicted by asymptotic safety.
