We develop a theoretical framework for ferroelectric–superconducting coupling in bilayer MoTe₂. Motivated by experiments showing hysteretic switching of superconductivity under an out-of-plane displacement field, we propose that inter-orbital pairing provides the microscopic origin of this behavior. Using Bogoliubov–de Gennes modeling and Landau–Ginzburg theory, we show that superconductivity can coexist with moderate polarization but is suppressed beyond a critical value, producing ferroelectric hysteresis between superconducting and resistive states. Our theory also captures the enhancement of Tc​ near polarization reversal and predicts experimental signatures that can help test the inter-orbital pairing scenario.
