  We investigate the prospects for discovering charginos and neutralinos at a
future $pp$ collider with $\sqrt{s} = 100$ TeV. We focus on models where
squarks and sleptons are decoupled -- as motivated by the LHC data. Our initial
study is based on models where Higgsinos form the main component of the LSP and
$W$-inos compose the heavier chargino states ($M_2 > \mu$), though it is
straightforward to consider the reverse situation also. We show that in such
scenarios $W$-inos decay into $W^\pm$, $Z$ and $h$ plus neutralinos almost
universally. In the $W Z$ channel we compare signal and background in various
kinematical distributions. We design simple but effective signal regions for
the trilepton channel and evaluate discovery reach and exclusion limits.
Assuming 3000 fb$^{-1}$ of integrated luminosity, $W$-inos could be discovered
(excluded) up to 1.1 (1.8) TeV if the spectrum is not compressed.
