While dark energy has dominated cosmic dynamics only since $z\approx0.7$, its energy density was still $\gtrsim5\%$ of the total out to $z\approx2.5$. We calculate model independent constraints on its fraction from future galaxy surveys, finding that the rise of dark energy could be detected at $3\sigma$ nearly out to $z\approx2.5$.
