The origin of baryon asymmetry of the Universe is one of the most fundamental open questions in physics. Charge-Parity (CP) violation is a key ingredient for explaining this asymmetry. While CP violation has been well established in meson systems for decades, the search for CP violation in baryon decays has drawn increasing attention in recent years. This proceeding summarizes the latest results on baryon CP violation from two major experiments: BESIII (Beijing Spectrometer III experiment) and LHCb (Large Hadron Collider beauty experiment). We review the experimental methods, key measurements, and the first observation of CP violation in baryon decays, highlighting their implications for testing the Standard Model and probing new physics.
