A summary of the story of the Higgs discovery is briefly discussed first. Further the most recent results in the Higgs sector from the CMS/ATLAS experiments obtained with the Run 2 dataset are detailed. Even if many results were found consistent with the Standard Model predictions, nevertheless a full reality of the Higgs mechanism and a precise measurement about the Higgs properties could not be established with the statistics of Run 2 data; in addition a wide scenario for searches for physics beyond Standard Model, even in the Higgs sector, opened. Double Higgs searches are a key element to access to the information of the Higgs self-coupling, even if non standard scenarios; recent results are summarized. An upgrade program is planned for the LHC, to possibly reach an integrated luminosity of 3000 fb-1, at the end of that decade. For this ultimate scenario the LHC detector will be upgraded to fully exploit the highly-demanding operating conditions and the delivered luminosity. Prospective studies to explore the CMS/ATLAS potential in the Higgs sector in the high luminosity scenario of the LHC will be also briefly summarized.
