Abstract: We investigate the viability of $f(Q)$ gravity as an alternative framework to address the $H_0$ and $S_8$ tensions in cosmology. Focusing on three representative $f(Q)$ models, we perform a comprehensive Bayesian analysis using a combination of cosmological observations, including cosmic chronometers, Type Ia supernovae, gamma-ray bursts, baryon acoustic oscillations, and redshift-space distortions. Our results demonstrate that most of these models can yield higher values of $H_0$ than those predicted by $Lambda$CDM, offering a partial alleviation of the tension. In addition, one model satisfies the condition $G_{mathrm{eff}} arXiv:2505.18264v1 Announce Type: new
