In this article, we take the scalar diquark and antidiquark as the basic constituents, construct the $C\gamma_5\otimes\stackrel{\leftrightarrow}{\partial}_\mu\otimes \gamma_5C$ type tetraquark current to study the $Y(10750)$ with the QCD sum rules. The predicted mass $M_{Y}=10.75\pm0.10\,\rm{GeV}$ supports assigning the $Y(10750)$ to be the diquark-antidiquark type vector hidden-bottom tetraquark state with a relative P-wave between the diquark pair.
