We propose a variant of T-model inflation called Tp-model Higgs inflation which is comfortably consistent with the recent ACT data. The model uses quartic potential and a kinetic pole which may originate from a rational Kahler potential. Within supergravity we employ a superpotential consistent with a gauge and an R symmetries and a shift-symmetric, rational Kahler potential. The model can be embedded into a B-L extension of MSSM which allows for a nice solution to the mu problem and baryogenesis via non-thermal leptogenesis  or natural values of the relevant parameters.
