We show that the jet power Pj and geometrically corrected γ -ray luminosity Lγ for the X-ray
binaries (XRBs) Cygnus X-1, Cygnus X-3, and V404 Cygni, and γ -ray upper limits for GRS
1915+105 and GX339-4, follow the universal scaling for the energetics of relativistic jets from
black hole (BH) systems found by Nemmen et al. for blazars and GRBs. The observed peak
γ -ray luminosity for XRBs is geometrically corrected, and the minimum jet power is estimated
from the peak flux density of radio flares and the flare rise time. The Lγ –Pj correlation holds
across ∼17 orders of magnitude. The correlation suggests a jet origin for the high-energy
emission from XRBs, and indicates a common mechanism or efficiency for the high-energy
emission 0.1–100 GeV from all relativistic BH systems.
