  The LHC Run-1 was very successful and included the discovery of a new
particle with mass of about 125 GeV compatible with the Higgs boson predicted
by the Standard Model. The prospects for Higgs physics at the high-luminosity
LHC and at future colliders are presented. In particular, the ultimate
precision attainable for the couplings measurements of the 125 GeV particle
with elementary fermions and bosons is discussed along with prospects for
self-coupling measurements, for the ATLAS and CMS detectors at the upgraded
LHC.
