In this article we present a calculation of the tetraquark ground-state energy using a diffusion Monte Carlo method to solve the non-relativistic many-body system. The static potential for the four quark system is chosen to align with the flux-tube picture of QCD. Using this approach, we find that the state has a mass of , which is around 100 MeV below twice the mass. This bound state can behave as a four-lepton resonance via its decay to Υ(1S)Υ(1S)*→ℓ⁺ℓ^-ℓ⁺ℓ^-
