The LHC experiments are probing the Standard Model in an unprecedented variety of ways. In addition to that, the search of what physics lies Beyond the Standard Model is one of the main quests of the ATLAS and CMS experiments at the LHC. In this regard, the upcoming High-Luminosity upgrade of the LHC is going to unlock new possibilities in terms of new physics searches, expanding the phase space of already probed models and investigating new kinds of exotic models that have never been studied before. We present an overview of the Phase-2 upgrades of the ATLAS and CMS experiments and how these upgrades are going to expand the reach of Beyond Standard Model searches.
