The recent surge of interest in altermagnetism, distinct from both ferromagnetism and antiferromagnetism, highlights its potential for a wide range of technological applications. Quantifying their topological transport properties can provide essential guidance on the characterization of such materials while assessing their suitability for spintronic and optical applications. In this work, we collect around 200 known altermagnets (including also those with odd parity) based on symmetry arguments and perform medium-throughput density functional theory calculations to evaluate their topological transport properties such as anomalous Hall conductivity, magneto-optical Kerr effect, and shift current. Focusing on cases with broken inversion symmetry (i.e., polar altermagnets and odd-parity magnets), it is observed that the shift current can be large, making them promising for bulk photovoltaic applications. Furthermore, taking ferroelectric Fe2Mo3O8 as an example, it is demonstrated that its shift current can be controlled by external electric fields. Our results provide significant features characterizing altermagnets, and the obtained electronic structure can be starting point to investigate other intriguing physical properties.
