In this article, we take the scalar diquark and antidiquark operators as thebasic 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. Thepredicted mass $M_{Y}=10.75\pm0.10\,\rm{GeV}$ and width $\Gamma_Y=33.60^{+16.64}_{-9.45}\,{\rm{MeV}}$ support assigning the $Y(10750)$ to be thediquark-antidiquark type vector hidden-bottom tetraquark state, which has arelative P-wave between the diquark and antidiquark constituents.

Vector hidden-bottom tetraquark candidate: $Y(10750)$
