Yes there is. The solution to the Friedmann equation in a flat universe with a cosmological constant is $$H^2 = \frac{8\pi G}{3}\rho + \frac{\Lambda}{3},$$ Thus, as the universe expands and the relative importance of gravitating matter, characterised by density $\rho$, decreases, then $\Lambda \simeq 3H^2$. We are already (just) in a dark energy dominated ...
