Solid evidence of quantum fluctuations associated to a quantum critical point in cuprate superconductors remains elusive. Here, Auvray et al. report Raman scattering evidence of enhanced electronic nematic fluctuations near the endpoint of the pseudogap phase in Bi$${}_{2}$$ 2 Sr$${}_{2}$$ 2 CaCu$${}_{2}$$ 2 O$${}_{8+\delta }$$ 8+δ .
