In this paper, we investigate the spectra of the prospective hidden-bottom and -charm hexaquark states with quantum numbers 
, 
, 
and 
in the framework of QCD sum rules. By constructing appropriate interpreting currents, the QCD sum rules analyses are performed up to dimension 12 of the condensates. Results indicate that there exist two possible baryonium states in b-quark sector with masses 
GeV and 
GeV for 
and , respectively. The corresponding hidden-charm partners are found lying respectively at 
GeV and 
GeV. Note that these baryonium states are all above the dibaryon thresholds, which enables their dominant decay modes could be measured at BESIII, BELLEII, and LHCb detectors.
