### Description

In this talk, we will discuss the present status of the di-Higgs searches at the LHC. We will quantify the prospects of witnessing signatures of these elusive modes in the $b \bar{b} \gamma \gamma$, $b \bar{b} \tau^+ \tau^-$, $b \bar{b} W W^*$, $W W^* \gamma \gamma$ and the $4W$ channels at the high luminosity run of the LHC (HL-LHC). We will emphasise the prospects of measuring the Higgs self-coupling at the futuristic 100 TeV FCC-hh collider when the two Higgs bosons are either produced in association with an additional hard jet or in association with a pair of top quarks. Finally, these constraints will be translated to the operator coefficients modifying the Higgs self-coupling.
