Using century-long monitored OJ287 supermassive black hole binary we set first DM-independent, dynamical constraints on their masses $\\mu = (8.5-22) \\times 10^{-22}$ eV. These dynamical constraints, driven by boson cloud friction, are robust against DM-model uncertainties and offer a novel ultralight boson probe.
