While dark energy has dominated cosmic dynamics only since $zapprox0.7$, its
energy density was still $gtrsim5%$ of the total out to $zapprox2.5$. We
calculate model independent constraints on its fraction from future galaxy
surveys, finding that the rise of dark energy could be detected at $3sigma$
nearly out to $zapprox2.5$.
