  Based on arXiv:1705.07935 and arXiv:1705.07917, we present the first global
fits of supersymmetric models using the new Global And Modular
Beyond-the-Standard-Model Inference Tool (GAMBIT). With GAMBIT we have
performed frequentist fits of the GUT-scale CMSSM, NUHM1 and NUHM2 models, as
well as the weak-scale MSSM7, extending existing results in terms of the number
of observables included, scanning techniques and treatment of nuisance
parameters. For the GUT-scale models our analyses show that a stop
co-annihilation scenario provides the best fit to current data, and that in the
CMSSM the stau co-annihilation scenario is ruled out at 95% confidence level.
For the MSSM7 we find that the best-fit scenario has light higgsinos and highly
under-abundant relic density due to efficient chargino co-annihilation.
