CP violation in baryon decays has recently garnered significant attention. Traditionally, CP violation in charmed baryon decays is predicted to be at the order of O (10^-4). Utilizing recent measurements from BESIII, Belle and Belle~II experiments, we conduct a comprehensive global analysis to estimate the contribution of topological diagrams in these processes. Our study reveals that topological diagrams alone cannot fully account for the experimental data. By incorporating new effects that are not included in traditional topological diagrams and exploring a novel way to determine the possible new weak phase, our analysis reveals the potential for significant CP violation in c^+ p / n ^+ and c^+ ⁰ K^+. This suggests a promising opportunity to observe CP violation for the first time in charmed baryon decays.
