Plasma wakefield acceleration presents an ambitious path toward 10 TeV-scale electron colliders. A defining feature of these machines is strong beam-beam interactions that generate substantial beamstrahlung, drastically reshaping the collision energy spectra. I will present results from a comprehensive study of five wakefield collider configurations, demonstrating that these beam-beam effects do not compromise (and can even enhance) the discovery potential for multi-TeV electroweak states. Key targets such as the thermal higgsino remain accessible across multiple search channels, even if positron acceleration proves challenging. I will also discuss resonance searches via radiative return and beamstrahlung, prospects for measuring the triple Higgs coupling, and comparisons with muon and hadron collider projections.
